Ina vacuum, it is a constant value that does not depend on the observer.
Answer:
Push and pull both are forces , but the difference is in their direction at which it is applied . If the force applied in the direction of motion of the particle then we call it as push . If that force applied in the direction OPPOSITE to the motion of particle then it is termed as pull
Parts made from blow molding are plastic, hollow, and thin-walled, such as bottles and containers that are available in a variety of shapes and sizes. Small products may include bottles for water, liquid soap, shampoo, motor oil, and milk, while larger containers include plastic drums, tubs, and storage tanks.
The final velocity of the 15 kg mass is 18.33 m/s.
<h3>
Conservation of linear momentum</h3>
The final velocity of the 15 kg mass can be determined by applying the principles of conservation of linear momentum as follows;
Where;
- m₁ is the mass of the first object = 25 kg
- u₁ is the initial velocity of the first object = 15 m/s
- m₂ is the mass of the second object = 15 kg
- u₂ is the initial velocity of the second object = -10 m/s
- v₁ is the final velocity of the first object = -2 m/s
- v₂ is the final velocity of the second object
Thus, the final velocity of the 15 kg mass after the collision is 18.33 m/s.

Answer and Explanation:
Warm air tends to rise, and cold air tends to fall, consequently, the hot air of the equator rises and at the same time the cold air of the poles descends to the ground. This generates wind currents that displace heat throughout the atmosphere.
The movement of water creates ocean currents that transport energy heat up the biosphere. Surface ocean currents heat or cool the air above
