The human eye is most sensitive to light having a frequency of about 5.30 1014 Hz, which is in the yellow-green region of the electromagnetic spectrum. How many wavelengths of this light can fit across the width of your thumb, a distance of about 2.0 cm

If the speed of the circular room is not changing at a constant rate, the angular velocity of the room would also not be constant. In this case, the magnitude of the centripetal acceleration would not be constant either.

To represent this scenario, we would need to plot the angular velocity (ω) as a function of time. The angular velocity would vary over time, resulting in a non-uniform centripetal acceleration. Consequently, the magnitude of the frictional force required to prevent the rider from sliding down the wall would also vary.

Without specific information about how the speed changes, it is challenging to provide detailed drawings or calculations. The situation would require a more complex analysis involving equations of motion, varying angular velocities, and time-dependent forces.

However, the general concept remains the same: to prevent the rider from sliding down the wall, the frictional force must be equal to or greater than the weight of the rider. The coefficient of static friction required would depend on the specific values of the varying angular velocity and other factors influencing the centripetal acceleration.

Answer:

1 m/s so number 2 is the right one

Explanation:

so when it is at rest it still has some of the left over energy so it would be at 1 m/s

Answer:

D: 4.4m/s

Explanation:

From a known theorem the total work on a body is equal of the variation of kinetic energy:

\(W = \Delta K = K_f-K_i = \frac12 mv_f^2 - \frac12 m v_i^2\)

Taking the first and last step in the chain of equalities and replacing the values we have, we get:

\(5 = \frac12(1)v_f^2 - \frac12(1)(3)^2\\10= v_f^2 -9 \rightarrow v_f^2 = 19 \rightarrow v_f=\sqrt19 \approx 4.4m/s\)

The correct answer for the given question for the distance that the piston on the right will move is 0.1 m option (A).

When an explosion occurs in the left piston, it exerts a force on the fluid, which in turn exerts an equal and opposite force on the right piston due to the enclosed volume.

The cross-sectional area of the left piston is 0.25 m², and assuming the force is uniformly distributed over the entire area, the force exerted by the left piston is given by F = P × A, where P is the pressure and A is the area.

Using the work-energy principle, the work done by the left piston is equal to the work done on the right piston. Therefore, the work done on the right piston is equal to the force exerted on it multiplied by the distance it moves.

The force exerted on the right piston can be calculated using the same formula as before (F = P × A), where the cross-sectional area A is 0.5 m².

Since the force exerted on the right piston is equal to the force exerted by the left piston, we can equate the two expressions for force and solve for the distance moved by the right piston.

Using the equation F_left = F_right, we have P_left × A_left = P_right × A_right.

Plugging in the given values, we get (P_left × 0.25) = (P_right × 0.5).

Since the pressure is the same throughout the fluid, P_left = P_right.

Simplifying the equation, we have 0.25 = (0.5 × A_right).

Solving for A_right, we get A_right = 0.25 / 0.5 = 0.5 m².

The distance moved by the right piston can be calculated using the work formula:

Work_right = Force_right × Distance_right.

Plugging in the values, we have (P_right × A_right) × Distance_right = (P_left × A_left) × Distance_left.

Since P_left = P_right, we can further simplify the equation:

A_right × Distance_right = A_left × Distance_left.

Plugging in the given values, we get (0.5 × Distance_right) = (0.25 × 0.2).

Solving for Distance_right, we have Distance_right = (0.25 × 0.2) / 0.5 = 0.1 m.

Hence, the correct answer is option A: 0.1 m.

Answer:

Kilograms (kg)

Explanation:

The amount of matter present in an object is called its mass. It is different from weight of an object as weight is the force of gravity acting on an object. Mass of an object remains same at every location. Mass of an object can never be equal to 0.

Mass of an object can be measured in many units like grams, pounds etc. But the SI unit of mass is kilogram or kg.

Hence, the correct option is (b).

The potential energy of the fighter jet of mass 'm' at a height of 10000 meters will be 98000m.

The energy of the body due to its position is called potential energy. If a body of mass 'm' is at height 'h' above the ground, then its potential energy with respect to earth will be -

E[P] = mgh

Given is a fighter jet traveling at a height of 10,000 meters.

The potential energy of a body at height 'h' above the ground is given by-

E[P] = mgh

where -

m is the mass of body

g is the acceleration due to gravity

Assume that the mass of jet fighter is 'm'. Then its potential energy will be -

E = mgh

E = m x 9.8 x 10000

E = 98000m

Therefore, the potential energy of the fighter jet of mass 'm' at a height of 10000 meters will be 98000m.

Entropy changes that are positive (+) indicate more chaos. The entropy of the universe is increasing. The entropy of a universe increases whenever there is any spontaneous change.

As the ice melts, the molecules grow disorganised as they are now able to move about. The water is then heated to transform into a gas, releasing the molecules to move freely through space. Both of the above reactions would have a positive entropy (DS).

Positive entropy indicates an increase in randomness in a system. Positive entropy processes include boiling and evaporation. A system has less randomness when the entropy is negative. A few instances of negative entropy processes include freezing and condensation.

Upon travelling at an altitude of 10.0 km, a passenger aircraft weighing 7.0 x \(10^{6}\) N  potential is the energy.

Potential energy and kinetic energy are fundamentally different from one another because one is the energy of what can be and the other is the energy of what is. Or to put it another way, potential energy is immobile and ready to be unleashed;

Due to the object's motion, kinetic energy loses some energy in the form of light energy, heat energy, and friction; these things do not occur in the potential energy, which is the reason why kinetic energy is not more than the potential energy.

The final speed of the heavier object= -v

In a head-on elastic collision, the conservation of momentum and kinetic energy principles can be applied to determine the final velocities of the objects. Let the final velocity of the mass m be v_m and the final velocity of the mass 3m be v_3m.

The conservation of momentum can be expressed as:

m * v + 3m * (-v) = m * v_m + 3m * v_3m

The conservation of kinetic energy can be expressed as:

0.5 * m * v^2 + 0.5 * 3m * (-v)^2 = 0.5 * m * v_m^2 + 0.5 * 3m * v_3m^2

By solving these equations simultaneously, we can find the final velocity of the heavier object, 3m:

Swimming in a pool requires that you push back on the water in order to go forward is Newton's 3rd Law.

Newton's 3rd Law, also known as the law of action and reaction, states that for every action, there is an equal and opposite reaction. This means that if an object A exerts a force on object B, then object B will exert an equal and opposite force on object A.

For example, if you push against a wall, the wall will push back on you with the same force in the opposite direction. This is because every force is a result of an interaction between two objects, and each object exerts an equal and opposite force on the other.

This law is important in understanding how objects interact with each other and is fundamental to many areas of physics, including mechanics, fluid dynamics, and electromagnetism.

The correct statement of Newton's Second Law is: An object's acceleration is inversely proportional to its mass and proportional to the net force acting on it.

Newton's Second Law of Motion states that the force acting on an object is directly proportional to the mass of the object and its acceleration. In other words, the greater the force applied to an object, the greater its acceleration, and the greater the object's mass, the less it will accelerate for a given force.

This law is often expressed mathematically as F = ma, where F is the force applied to an object, m is the object's mass, and a is its acceleration.
