The answer is B because there is a total of 10N to the right and 5 to the left, 10-5=5
Answer:
Explanation:
work done=force * displacement
=500 N * 40 m
=2000 joule
The term you need to know is equilibrium. Technically it means that heat gained = heat lost. Normally in beginning chemistry classes the evidence for this condition is a stable temperature.
Answer:
1. All electromagnetic waves travelS at 3×10⁸m/s in vacuum
2.They are transverse in nature.
3.they can travel through vacuum.( doesn't require any materials for their transmission.
4.They under go phenomena of diffraction,reflection, refraction, interference and polarization.

Answer:
v = 54.2 m / s
Explanation:
Let's use energy conservation for this problem.
Starting point Higher
Em₀ = U = m g h
Final point. Lower
= K = ½ m v²
Em₀ = Em_{f}
m g h = ½ m v²
v² = 2gh
v = √ 2gh
Let's calculate
v = √ (2 9.8 150)
v = 54.2 m / s
