Answer:
Twice as fast
Explanation:
Solution:-
- The mass of less massive cart = m
- The mass of Massive cart = 2m
- The velocity of less massive cart = u
- The velocity of massive cart = v
- We will consider the system of two carts to be isolated and there is no external applied force on the system. This conditions validates the conservation of linear momentum to be applied on the isolated system.
- Each cart with its respective velocity are directed at each other. And meet up with head on collision and comes to rest immediately after the collision.
- The conservation of linear momentum states that the momentum of the system before ( P_i ) and after the collision ( P_f ) remains the same.

- Since the carts comes to a stop after collision then the linear momentum after the collision ( P_f = 0 ). Therefore, we have:

- The linear momentum of a particle ( cart ) is the product of its mass and velocity as follows:
m*u - 2*m*v = 0
Where,
( u ) and ( v ) are opposing velocity vectors in 1-dimension.
- Evaluate the velcoity ( u ) of the less massive cart in terms of the speed ( v ) of more massive cart as follows:
m*u = 2*m*v
u = 2*v
Answer: The velocity of less massive cart must be twice the speed of more massive cart for the system conditions to hold true i.e ( they both come to a stop after collision ).
Answer:
Scientists have determined that humans are disrupting the nitrogen cycle by altering the amount of nitrogen that is stored in the biosphere. The chief culprit is fossil fuel combustion, which releases nitric oxides into the air that combine with other elements to form smog and acid rain.
Answer:
Circular wave
Explanation:
Circular waves are special types of mechanical waves. They all travel through a material medium or some times a vacuum.
An example of such wave is a ripple caused by dropping a stone in a tank of water.
A wave that propagates in circular form on the surface of water falls into this category.
Answer:
Its a parallel connection
Explanation:
The bulbs aren't in one line but two different parts, which makes it a parallel connection instead of a series connection.
The tearing of paper is physical as it's still paper even when you tear it. A chemical reaction is when the substance is chemically change. ... When paper is burn, the cellulose in the air reacts with the oxygen to form carbon dioxide and water.
Therefore it's chemistry.
