Answer:
Acceleration (a) is defined as the rate of change of velocity. Velocity is a vector quantity, and therefore acceleration is also a vector quantity. The SI unit of acceleration is metres/second2 (m/s2).
Answer:
Explanation:
Magnitude of tension
= centripetal force
= m ω²R
= m (2π/T)² R , T is time period of revolution.
= .085 x (2 x 3.14 / .55)² x .84
= 9.3 N .
Answer:
By throwing wrenches and screwdrivers away the side of spaceship he might be able to get back.
Explanation:
<em>Theory</em>
<u>The law of conservation of linear momentum</u>
The sum of linear momentum of a closed system under no external unbalance force remains the same.
Here consider the astronaut and the wrenches and screwdrivers as a system.
System in the empty space so no external unbalance force exerted on the astronaut. As the linear momentum is conserved when he throw wrenches and screwdrivers away form the space ship he will gain an equal momentum in the opposite direction. So he gains a certain velocity which he can use to drift towards the spaceship.
