What is the resistance of a 150 W light bulb running on a 120 V circuit 

Answer:

4.96×10¯¹⁰ N

Explanation:

The following data were obtained from the question:

Mass 1 (M1) = 300 Kg

Mass 2 (M2) = 300 Kg

Separating distance (r) = 110 m

Gravitational constant (G) = 6.67×10¯¹¹ Nm²/Kg²

Gravitational force (F) =?

The gravitational force between the two goal posts can be obtained as follow:

F = GM1M2 / r²

F = 6.67×10¯¹¹ × 300 × 300 / 110²

F = 6.003×10¯⁶ / 12100

F = 4.96×10¯¹⁰ N

Therefore the gravitational force between the two goal posts is 4.96×10¯¹⁰ N

Answer: The force produced by piston B is 0.006 N.

Explanation:

No problem! We can convert the area of piston B to square meters to make the units consistent:

Area of piston B = 0.1 cm^2 = 0.1 x (0.01 m/cm)^2 = 0.00001 m^2

Now we can use the formula:

pressure = force/area

For piston A, we have:

pressure = 6 N / 0.01 m^2 = 600 Pa

So the pressure in the liquid is 600 Pa.

To find the force produced by piston B, we rearrange the formula:

force = pressure x area

Using the pressure we just found and the area of piston B, we get:

force = 600 Pa x 0.00001 m^2 = 0.006 N

So the force produced by piston B is 0.006 N.

Explanation:

Edothermic process is the absorbtion of heat.

It is the opposite of exothermic process which is the release of energy. In edothermic process thermal energy is absorbed from the surrounding

The final temperature of the aluminum piece is approximately 69.44 °C.

To calculate the final temperature, we can use the formula:

Q = m * ce * ΔT

Where:

Q is the amount of heat absorbed (20 kJ, or 20,000 J),

m is the mass of the aluminum (450 g),

ce is the specific heat capacity of aluminum (0.9 J/g °C),

ΔT is the change in temperature.

We need to solve this formula for ΔT to find the change in temperature. Rearranging the formula, we have:

ΔT = Q / (m * ce)

Substituting the given values, we get:

ΔT = 20,000 J / (450 g * 0.9 J/g °C)

Simplifying further:

ΔT = 44.44 °C

Since the initial temperature is 25 °C, the final temperature is calculated by adding the change in temperature to the initial temperature:

Final temperature = Initial temperature + ΔT

Final temperature = 25 °C + 44.44 °C

Final temperature ≈ 69.44 °C

Therefore, the final temperature of the aluminum piece is approximately 69.44 °C.

Answer:

We don't know how much it cost bc u didn't give us a number of how much one person cost or any details but if you add both of the balls together they have 1,400 balls

To calculate the cost of paintballing for Ryan and his dad, we need to know the cost per paintball. Once we have that information, we can multiply it by the total number of paintballs they used (700 balls each).

Let's say the cost per paintball is $0.50.

For Ryan:

Cost for Ryan = Cost per paintball × Number of paintballs used by Ryan

Cost for Ryan = $0.50/ball × 700 balls = $350

For his dad:

Cost for Dad = Cost per paintball × Number of paintballs used by Dad

Cost for Dad = $0.50/ball × 700 balls = $350

Total cost for both of them:

Total Cost = Cost for Ryan + Cost for Dad

Total Cost = $350 + $350 = $700

So, the total cost of paintballing for Ryan and his dad is $700, assuming the cost per paintball is $0.50.

The magnitude of the total force exerted by two charges on a third charge is approximately 2.656e-07 N.

The magnitude of the total force exerted by two charges on a third charge is given by the following equation:

\(F = k |q1q2| / r^2\)

where:

In this problem, we are given the following information:

q1 = 1.0e-9 C

q2 = 2.0e-9 C

q3 = 5.30 nC

y3 = -0.420 m

The distance between the third charge and the midpoint of the two charges can be calculated using the following equation:

\(r = \sqrt((y1 - y3)^2 + (y2 - y3)^2)\)

where:

In this problem, we are given that y1 = 0.200 m and y2 = 0.400 m. Therefore, the distance between the third charge and the midpoint of the two charges is:

\(r =\sqrt((0.200 - (-0.420))^2 + (0.400 - (-0.420))^2) = 0.353 m\)

Therefore, the magnitude of the total force exerted by the two charges on the third charge is:

\(F = 8.987551787e9 * |1.0e-9 * 2.0e-9| / (0.353)^2\) = 2.6560145212572496e-07 N

The distance between the 7th and the tenth second is 29.4 m.

We know that we can have to formulate the information that has been given here so as to obtain a proper progression and this would help us to get the common difference of the progression that we are looking at.

Now we know that the progression would look something like; 4.9, 14.7, 24.5 ....

We can see that this is an arithmetic progression that has a common difference of 9.8.

U7 = a + (n - 1)d

a = first term

n = Number of terms

d = common difference

U7 = 4.9 + (7 - 1) 9.8

= 63.7

U10 = 4.9 + (10 - 1) 9.8

U10 = 93.1

The statement is True because If the control requirements are very complex or extensive, a double relay can be installed. A double relay is a type of electrical relay that includes two separate relay circuits within a single housing.

Double relays are a type of control system that consists of two separate relay circuits that work in parallel to control a process or system. If one relay circuit fails, the other circuit takes over and continues to provide control, preventing any dangerous situations from occurring.

This redundancy is crucial in applications where safety is a top priority, as it ensures that the system will continue to operate even in the event of a failure. In industrial settings, such as chemical plants, power plants, and oil refineries, double relays are often used to prevent accidents that could be caused by equipment failure or malfunction.

These relays can also be found in aerospace and military systems, where failure could have catastrophic consequences. Overall, the use of double relays is an important safety measure that helps to ensure the reliable and safe operation of critical systems.

The apparent weight of the person in the elevator during acceleration is 85% of their actual weight.

When an elevator accelerates, there is an upward or downward force acting on the passengers inside. In this case, the elevator is accelerating downward, which means there is a net downward force acting on the person. This force is responsible for the person's apparent weight, which is different from their actual weight.

During the acceleration phase, the apparent weight is 85% of the actual weight. This means that the net force acting on the person is equal to 85% of their weight. The remaining 15% of the weight is counteracted by the normal force exerted by the elevator floor.

Once the elevator reaches a constant speed, it is no longer accelerating. At this point, the net force acting on the person becomes zero, and their apparent weight matches their actual weight. The normal force exerted by the elevator floor is now equal to their full weight, balancing the force of gravity.

It's important to note that the apparent weight is determined by the net force acting on the person, which is the difference between the force of gravity and the normal force.

When the elevator accelerates, this net force changes, leading to a difference between the apparent weight and the actual weight. However, once the elevator reaches a constant speed, the net force becomes zero, and the apparent weight returns to the actual weight.

a) The tangential speed of the ball is 1.26 m/s

b) The centripetal acceleration of the ball is 1.99 m/s^2.

We need to use the formulas for tangential speed and centripetal acceleration:

Tangential speed = radius x angular speed

Centripetal acceleration = (tangential speed)^2 / radius

Given:

Mass of the ball, m = 5.00 kg

Radius of the circle, r = 0.800 m

Angular speed, ω = 0.500 rev/s

We need to convert the angular speed from revolutions per second to radians per second:

ω = 0.500 rev/s x 2π rad/rev = 1.57 rad/s

(a) Tangential speed of the ball:

v = rω = 0.800 m x 1.57 rad/s = 1.26 m/s

The angle of refraction when a ray of light passes from air into water at an angle of 50.0° to the surface of the water is approximately 34.4°, and the speed of light in water is about 2.26 x 10⁸ m/s.

When light passes from one medium to another, it undergoes refraction, which involves a change in direction and speed. The angle of refraction is determined by Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the speeds of light in the two media.

In this case, the angle of incidence is 50.0° and the medium changes from air to water. By applying Snell's law, we can calculate the angle of refraction to be approximately 34.4°.

The speed of light in a medium is determined by the refractive index, which is the ratio of the speed of light in vacuum to the speed of light in the medium. The refractive index of water is approximately 1.33.

Therefore, the speed of light in water can be found by dividing the speed of light in vacuum (approximately 3 x 10⁸ m/s) by the refractive index, resulting in approximately 2.26 x 10⁸ m/s.

X will lift faster and easier than Y because of X lift with maximum speed with minimum energy consumption.

First we have to find from that we get to know that which windlass will lift faster,

For windlass X,

Torque(X)=weight x radius of drum

                 =50x9.81x0.25=122.625 Nm

Torque (Y)=weight x radius of drum

                  =50x9.81x0.375=183.93 Nm

As we know that,

Equation of Power= Torque x Angular velocity

And Angular velocity (w)= 2 x pi x N/60

Therefore Torque is inversely proportional to speed. Thus, when speed of the car is increasing , decreaseing of torque will start.According to above sentence ,windlass X have maximum speed of lift and windlass Y have comparatively low speed.Also power is directly proportional to Torque, so maximum torque used maximum energy and vice versa.

The distance traveled between seconds 3 and 4 is greater than the distance traveled between seconds 1 and 2 because: an object falling due to gravity moves faster every second. Hence, option (C) is correct.

Any motion of a body in which gravity is the only force acting on it is referred to as free fall in Newtonian physics.

An object may not necessarily be falling down in the traditional sense of the word while it is in a "free fall" in a technical sense. Even if an object going upwards isn't typically thought of as falling, it is said to be in free fall if it is just being affected by gravity.

As during feel force gravitational force works on the object continuously, the velocity of the object increases continuously. Hence, the distance traveled between seconds 3 and 4 is greater than the distance traveled between seconds 1 and 2 .
