(a) The momentum of the proton is determined as 5.17 x 10⁻¹⁸ kgm/s.
(b) The speed of the proton is determined as 3.1 x 10⁹ m/s.
<h3>
Momentum of the proton</h3>
The momentum of the proton is calculated as follows;
K.E = ¹/₂mv²
where;
- m is mass of proton = 1.67 x 10⁻²⁷ kg
- v is speed of the proton = ?
<h3>Speed of the proton</h3>
v² = 2K.E/m
v² = (2 x 50 x 10⁹ x 1.602 x 10⁻¹⁹ J)/(1.67 x 10⁻²⁷)
v² = 9.6 x 10¹⁸
v = 3.1 x 10⁹ m/s
<h3>Momentum of the proton</h3>
P = mv = (1.67 x10⁻²⁷ x 3.1 x 10⁹) = 5.17 x 10⁻¹⁸ kgm/s

Answer:
B) The wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave
Answer:
c) 17 m
Explanation:
From the conservation of energy.
Change in kinetic energy= change in potential energy
Now,
Now according to the situation.
Here, v is the velocity, m is the mass of an object, h is the height, g is the acceleration due to gravity.
Given that the speed of the bicycle is
And the acceleration due to gravity is
Substitute these values.
Which means it is equivalent to 17 m
Therefore, the maximum height is 17 m
the answer A. since power is Joules/seconds and energy is rated in Joules
