5 0

Answer:

E = 21.22 ×10⁻³⁶ J

Explanation:

Given data:

Energy of photon = ?

Frequency of photon = 3.2×10⁻² Hz

Solution:

Formula:

E = hf

h = 6.63×10⁻³⁴ Js

Now we will put the values in formula.

E = 6.63×10⁻³⁴ Js × 3.2×10⁻² Hz

E = 21.22 ×10⁻³⁶ J    (Hz= s⁻¹)

vlabodo [156]

Answers: -

For high kinetic energy, the object must have high speed of movement.

1) An airplane has a lot of kinetic energy. Airplanes move at high speed and thus posses a lot of kinetic energy.

2) A bullet from a gun has a lot of kinetic energy due to the high speed of bullet.

3) A formula one car moving at high speeds have a lot of kinetic energy.

4) A train moving at high speed has lots of kinetic energy.

5) An asteroid has a lot of kinetic energy due to it's high speed.

6) A roller coaster moving at high speeds have a lot of kinetic energy.

7) A missile fired from a fighter plane has lots of kinetic energy.
