From the photoelectric effect we learn that A. a blue photon has less energy than a red photon B. a blue photon has equal energy
emmainna [20.7K]

Answer: E. None of the above

Explanation: The energy of a photon is given by the formula below.

E=hf or E = hc/λ

E = energy, h = planck constant, c= speed of light and

λ= wavelength.

From E=hf we can see that energy is directly proportional to frequency since h is a constant, this implies that as we move up the visible light spectrum, red light has the least frequency this accounting for the lowest energy while violet has the largest energy accounting for a very high energy.

Blue light is higher in the spectrum than red light.

This implies that blue light has more energy than red.

Visible light is part of the electromagnetic spectrum which implies that they all travel with the same speed of a constant value ( speed of light = 3* 10^8 m/s).

Thus in conclusion, blue light has more energy that red light but they both travel with the same speed.

This point nullifies the options thus making none of it correct.

A 2kg ball is thrown upward with a velocity of 15 m/s what is the kinetic energy of the ball being thrown?
vivado [14]
Kinetic Energy, or K.E is equal to 1/2 times the mass of an object times the velocity squared.

Therefore K.E
=  \frac{1}{2}  \times 2 \times  {15}^{2}
which is 225

Energy is expressed in joules (J)
so the K.E of the ball is 225J

Hope this helped

Identify the physical property of a material that plays an important role in determining if the collision is elastic or not base
Nutka1998 [239]

Answer:

They are spherical and hollow (not compact or dense)

Explanation:

An elastic collision is a form of a collision where kinetic energy and momentum are conserved in the process. When there is zero loss of kinetic energy and momentum, it is called a perfectly elastic collision.

This form of collision is observed in atmospheric gases and colliding balls which happens to be spherical and hollow.

Unrestrained occupants of a car keep moving during the time the car takes to stop due to ________.
elena-14-01-66 [18.8K]

Answer:

C.inertia

Explanation:

Inertia is a property of matter to<u> maintain its state of motion</u>.

In this case, if the car was moving along with the people in it when the car stopped, the inertia of the people will cause them to continue moving.

This is why in a crash a person can be shot from the car, due to the inertia he has from his previous state of motion.

The complete sentence is: Unrestrained occupants of a car keep moving during the time the car takes to stop due to<u> inertia. </u>(option C)

Two students stand at rest, facing each other on frictionless skates. They then start tossing a heavy ball back and forth betwee
Rzqust [24]
<span>The students will move away from each other as explained by Newton’s Third Law which states that “To every action, there is an equal and opposite reaction.” If the students are on frictionless skates, their action of throwing the ball will propel them in the opposite direction. Once the motion is initiated, they continue to move away from each other unless stopped by another force.</span><span />
