Answer:
Explanation:
Energy is directly proportional to frequency and it is given as:
E = hf
where h = Planck's constant
f = frequency
To get frequency, we use the formula of speed:
c = λf
where c = speed of light
λ = wavelength
=> f = c/λ
Therefore, the energy of the photon will be:
E = hc/λ
The energy of the photon is

The term that describes the movement of an object under the influence of gravity without air resistance is free fall
Answer:
both cannonballs hit the ships with the same horizontal speed
Explanation:
Hello!
A parabolic motion is characterized in that its vertical component in Y is constantly changing, this is due to the constant downward acceleration of gravity.
When the movement starts the speed at Y is maximum, then when it reaches its maximum height point its speed is zero, and finally it begins to increase downwards until it touches the floor.
On the other hand, the horizontal speed remains constant AS THERE IS NO ACCELERATION IN HORIZONTAL DIRECTION.
therefore both cannonballs hit the ships with the same horizontal speed
