Answer:

Explanation:

Metals are good conductor of electricity, because as per there structure they have free electrons which help them to move freely within the metal thus helps to maintain a good flow of electricity.

This theory has really helped engineers especially for making powerful batteries. As good batteries means amount of electricity drawn from it will be great and that too for longer time.

Hence such metals are used to make batteries that has more number of free electrons and thus can contribute to generate more electricity.

Good conductors can give us more electrical energy. Advanced batteries today use ion charges for the batteries.

In a collision, a 25.0 kg mass moving at 3.0 m/s transfers all of its momentum to a 5.0 kg mass.
nadezda [96]

Answer:

Explanation:

The momentum of the 25 kg mass is

p=mv

p=25kg*3m/s= 75kg*m/s

If this whole momentum of the object is transferred to the 5.0 kg object then according to the law of conservation of momentum, the momentum of the 25.0 kg object must be transferred to the 5.0 kg object:

75kg*m/s = 5.0kg*v

v=\dfrac{75}{5}

\boxed{v=15m/s}

An object experiences an impulse, moves and attains a momentum of 200 kg·m/s. If its mass is 50 kg, what is its velocity?
Nady [450]

Answer:

4 m/s

Explanation:

Momentum is defined as:

p=mv

where

m is the mass of the object

v is its velocity

For the object in this problem, we know:

p = 200 kg m/s is the momentum

m = 50 kg is the mass

Solving for the velocity, we find:

v=\frac{p}{m}=\frac{200}{50}=4 m/s
