Answer: - 25.2 kgm/s
Explanation: The mass of the ball is 0.5kg, and the initial velocity = 10.6m/s.
The final velocity is in opposite direction of the initial hence final velocity (v) = - 19.9 m/s
Impulse = change in momentum = final momentum - initial momentum.
Final momentum = mass × final velocity
Final momentum = - 19.9 × 0.5
Final momentum = - 9.95 kgm/s
Initial momentum = mass × initial velocity
Initial momentum = 0.5 × 10.6 = 5.3kgm/s
Change in momentum = final momentum - initial momentum = - 19.9 - 5.3
Change in momentum = - 25.2 kgm/s
The negative sign implies that the change in momentum is the opposite direction relative to the first.
False. First Law of Newton states that object tends to be at rest until an external force is applied and vice-versa.
decay series consists of radioactive nuclides produced by
successive radioactive decay until a stable nuclide is reached. (…)
Answer:
what are you asking exactly?
The frequency of the light beam is 4.72 x 10¹⁴ Hz.
<h3>
Frequency of the light beam</h3>
The frequency of light beam and wavelength of light is related in the following equations;
c = fλ
where;
- c is the speed of light = 3 x 10⁸ m/s
- f is the frequency
- λ is the wavelength
f = c/λ
f = (3 x 10⁸) / (636 x 10⁻⁹)
f = 4.72 x 10¹⁴ Hz
Thus, the frequency of the light beam is 4.72 x 10¹⁴ Hz.
