Answer:
it transforms it into high carbon alloy that is harder and can be sharper but is also more brittle in the process.
Explanation:
Answer:
The velocity of the arrow after 3 seconds is 30.02 m/s.
Explanation:
It is given that,
An arrow is shot upward on the moon with velocity of 35 m/s, its height after t seconds is given by the equation:

We know that the rate of change of displacement is equal to the velocity of an object.

Velocity of the arrow after 3 seconds will be :

So, the velocity of the arrow after 3 seconds is 30.02 m/s. Hence, this is the required solution.
Answer:
True
Explanation:
In an alternating current, voltage levels can be easily increased or decreased as per the requirements of the energy distribution in practical world.
Hence, the given statement is true
Answer:
25 meters = 1 minute
505 meters = ? minutes
Therefore, 505/25
Therefore, 101/5
Therefore, 2.2 minutes
It moves 505 meters in 2.2min
The answer is A) velocity, because velocity is speed and displacement.
Hope this helps
