Answer:
-v/2
Explanation:
Given that:
- Collides with the wall going through a sliding motion on on the plane smooth surface.
- Upon rebounding from the wall its kinetic energy becomes one-fourth of the initial kinetic energy before collision.
<u>We know, kinetic energy is given as:</u>
consider this to be the initial kinetic energy of the body.
<u>Now after collision:</u>
Considering that the mass of the body remains constant before and after collision.
Therefore the velocity of the body after collision will become half of the initial velocity but its direction is also reversed which can be denoted by a negative sign.
One way to increase or decrease the strength of the magnetic field is to change the number of loops in the coil. The more loops you add, the stronger the field will become. The more loops you remove, the weaker the field will become.
Answer:
the extension would be less the new extension might be 3 cm
Explanation:
Answer:
Geothermal power can provide consistent electricity throughout the day and year - continuous baseload power and flexible power to support the needs of variable renewable energy resources, such as wind and solar. Sustainable Investment.

Answer:
81.81 kg
Explanation:
= Mass of person = 78.4 kg
= Mass of canister
= Initial velocity of person = 0
= Initial velocity of canister = 3.5 m/s
= Final velocity of person = 2.4 m/s
= Final velocity of canister = 1.2 m/s
The momentum balance in the system is given by
Mass of the canister is 81.81 kg.
