Work done = force * distance
work done = 200 * 20
work done = 4000J
Answer:

Explanation:
As we know that magnitude of two vectors is given as

here we know that
A = magnitude of vector A
B = magnitude of vector B
= angle between two vectors
so here we know that
A = 30 units
B = 40 units
angle = 90 degree
so we have



protons, neutrons, and electrons.
Answer:
Vector sum of two vectors at right angles
p={p₁²+p₂²} =2 =1.41 kg•m/s
Explanation:
The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet.
