Answer:
True
Explanation
When an object slows down the Acceleration is in the other direction which “ slows it down
Answer:
15.75 m/s
Explanation:
v = Velocity of the combined mass of astronaut and tools = 1.8 m/s
= Mass of astronaut = 124 kg
= Mass of tools = 16 kg
= Velocity of astronaut = 0
= Velocity of tools
As linear momentum is conserved

The velocity of the tools is 15.75 m/s
Answer:
The length of the specimen after the load is released is 11.67 cm
Explanation:
Given;
yield stress, Y = 350 MPa
ultimate tensile stress, T = 300 MPa
Elongation factor, e = yield stress, Y / ultimate tensile stress, T
Elongation factor, e = 350 Mpa / 300 Mpa
Elongation factor, e = 1.1667
New length of the specimen = 1.1667 x 10 cm = 11.67 cm
Therefore, when the load is released from 10 cm long tensile specimen, the length of the specimen becomes 11.67 cm
Answer:
Explanation:
It transmits energy into the medium through its vibration. More energetic vibration corresponds to larger amplitude. The molecules move back and forth more vigorously. The loudness of a sound is also determined by the sensitivity of the ear.
