As we already know that intensity of light used is proportional to the no of electrons emitted per unit of time from the metal plate in the photoelectric effect and does not affect the energy of the emitted electrons and so the stopping potential of the photoelectric cell.

so, if we treat light as a packet of energy and follow quantum theory then it can only emit the electrons as energy is provided as a whole and there is no gap between the striking of photons and the emission of electrons from the metal plate but if we follow the classical theory of light being a wave than the intensity does not matter and no electron can be emitted as energy is provided in continuous form as energy can't be stored and used together.

According to the available choices, the criterion that the sleep cycle alarm clock failed to meet is "It did not solve the problem." This is because the options were shown to you.

The goal of a sleep cycle alarm clock is to assist its users in waking up at the most restorative and energising point in their natural sleep cycle. This will allow for a more revitalised and productive start to the day.

On the other hand, if the sleep cycle alarm clock was unable to properly achieve this goal and did not provide a solution to the issue of waking up feeling refreshed, then it would not match the desired requirement.

The other possibilities that were brought up, such as cost-effectiveness, availability, and safety, are examples of other criteria that could have an effect on the overall evaluation of the sleep cycle alarm clock.

Answer:

this statement is true because I looked it up

Sergio put a force of 1.2 newtons on the object to perform 30 joules of work by pushing it 25

What is force?

Force is a physical quantity that describes the interaction between two objects, causing a change in their motion. It is measured in units of newtons (N) and is defined as the product of an object's mass and acceleration, as described by Newton's second law of motion.

The force exerted by Sergio on the object can be calculated using the formula:

Work = Force × Distance × cos(theta)

where Work is the work done (in joules), Force is the force applied (in newtons), Distance is the distance moved (in meters), and cos(theta) is the cosine of the angle between the force and the direction of motion (assuming the force is applied parallel to the direction of motion, cos(theta) = 1).

Rearranging the formula, we get:

Force = Work / (Distance × cos(theta))

Substituting the given values, we get:

Force = 30 J / (25 m × cos(0°))

Since cos(0°) = 1, we can simplify the expression to:

Force = 30 J / 25 m

Force = 1.2 N

Therefore, Sergio put a force of 1.2 newtons on the object to perform 30 joules of work by pushing it 25

Answer:

A force of 355 N is applied to an object that accelerates at a rate of 7.8 m/sec2 . What is the mass of the object ?

Explanation:

The average change in momentum for the car during the trip is 8400 kg·m/s.

What is Momentum?

Momentum is a vector quantity, meaning it has both magnitude and direction. The direction of momentum is the same as the direction of velocity, and its magnitude is proportional to both the mass and the velocity of the object.

Then, we calculate the final momentum of the car during the remaining 3 hours:

Final momentum during the remaining 3 hours = mass × final velocity during the remaining 3 hours = m × v2

Now, we can calculate the average change in momentum:

Average change in momentum = Final momentum - Initial momentum

= (Final momentum during the first 2 hours + Final momentum during the remaining 3 hours) - Initial momentum

= [(m × v2) + (m × v2)] - (m × v1)

= 2m × v2 - m × v1

Plugging in the given values:

Mass of the car (m) = 1400 kg

Initial velocity (v1) = 32 m/s

Final velocity during the first 2 hours (v2) = 38 m/s

Average change in momentum = 2m × v2 - m × v1

= 2 × 1400 kg × 38 m/s - 1400 kg × 32 m/s

= 53200 kg·m/s - 44800 kg·m/s

= 8400 kg·m/s

Answer:

30 N

Explanation:

Since the car travels at a steady speed of 20m/s and has a driving force of 30N, there is no net acceleration and thus, the resistive force is also 30 N in magnitude but in the opposite direction to the driving force. This is shown below.

F - f = f' where F = driving force = 30 N. f = resistive force and f'= net force.

f' = 0 since there is no acceleration. So,

F - f = 0

F = f = 30 N

The right answer is "30 N"

Answer explanation:

If a car is travelling at a steady speed, the resultant force must be zero, so the driving force and resistive force must be equal and opposite.

In the circuit, the total current is 60 A and the voltage is 240 V. If R1

resistance is 20 Ω, then the R2 resistance  would be 5 Ω

Resistance is the obstruction of electrons in an electrically conducting material. The SI unit of the resistance is Ohm

The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.

V=IR

where V is the voltage

I is the current

R is the resistance

For the given problem V= 240 V and I = 60 A

R = V/I

R =240/60

R =4 Ω

For calculating equivalent resistance in parallel combination.

1/Re = 1/R1  + 1/R2

The 10 MSun black hole would exert the weakest tidal forces on an object near its event horizon.

option A.

The strength of tidal forces experienced by an object near the event horizon of a black hole depends on the mass and the size of the black hole. The tidal forces increase as the black hole's mass and size increase.

Therefore, the 10 MSun black hole would exert the weakest tidal forces on an object near its event horizon, followed by the 100 MSun black hole and the 10^6 MSun black hole, respectively.

This is because a smaller black hole has a smaller radius, which means that the gravitational pull on an object near the event horizon is weaker. Additionally, the tidal forces are determined by the difference in gravitational force felt by different parts of an object, which is smaller for a smaller black hole.

When the distance between the charged parallel plates of a capacitor is halved from d to d/2, the potential difference across the plates will remain the same.

The potential difference (V) across the plates of a capacitor is directly proportional to the electric field (E) between the plates and the distance (d) between them. Mathematically, V = Ed.

When the distance between the plates is halved to d/2, the electric field between the plates will double in magnitude. This is because the electric field is inversely proportional to the distance between the plates. Thus, E' = 2E.

Now, let's consider the potential difference across the plates when the distance is halved. Since V = Ed, the new potential difference V' can be calculated as V' = E'd/2. Substituting the values, we get V' = (2E)(d/2) = Ed = V.

From the equation, we can observe that the potential difference V' across the plates remains the same as the initial potential difference V. Therefore, when the distance between the charged parallel plates of a capacitor is decreased to d/2, the potential difference across the plates will remain unchanged.
