Answer: A satellite with a mass of 110 kg and a kinetic energy of 3.08×10^9 J must be moving at a speed of 7483 m/s.
Explanation: To find the answer we need to know about the kinetic energy of a body.
<h3>
How to solve the problem the equation of kinetic energy?</h3>
- We have the expression for kinetic energy of a body as,
- We have to find the speed of the satellite,
Thus, we can conclude that, the velocity of the satellite will be 7438m/s.

Answer:
laser's wavelength λ = 597.4 nm
Explanation:
Given:
Slit spacing, d = 1.17mm
Tenth bright fringe y = 4.57cm
Distance from slits, D = 8.95m
n = 10
λ = (d * y) / (D * n)
λ = (1.17x10⁻³ * 4.57x10⁻²) / (8.95 x 10)
λ = 5.3469x10⁻⁵ / 8.95x10¹
λ = 0.5974 x 10⁻⁵⁻¹
λ = 0.5974 x 10⁻⁶ m
λ = 597.4 x 10⁻⁹ m
λ = 597.4 nm
Answer:
Impulse is 0.4 x 18= 7.2
Explanation:
Impulse is defined as the integral of force over the time duration. When you do the integration of Newtons second law, momentum is
= Δp
If momentum p is defined as the integral of force per unit time, then we can take the area under the curve to find momentum, as the area under the curve can approximate the integral of the function.
Therefore, to quickly summarize, taking the maximum force, 18N , multiplied by duration of the interaction, which is 0.5s-0.1s=0.4s, will give your momentum, in the units of kg•m/s.
Hope that helps!
