<h2>Answer:The total momentum before collision is equal to the total momentum after collision.</h2>

Explanation:

Conservation of momentum states that whenever no external force is acting on a system,the total momentum is constant.

When we consider collisions,take the system as the two bodies that are colliding.

There are no external forces acting on the system.The forces that one body exerts on other come under internal forces.

So,momentum can be conserved in this case.

So,the total momentum before collision is equal to the total momentum after collision.

A wind generator, such as the one shown , uses the power of wind to generate electricity What do you think is happening inside t
sesenic [268]

Answer:

A wind turbine captures the wind, which then produces a renewable energy source. The wind makes the rotor spin; as the rotor spins, the movement of the blades drives a generator that creates energy. The motion of the blades turning is kinetic energy. It is this power that we convert into electricity.

Unlike most real bulbs, the resistances of the bulbs in the questions below do not change as the current through them changes. A
Shkiper50 [21]

Answer:

Option 1 is correct.

The current passing through the brighter bulb is larger.

Explanation:

The brightness of the bulb is determined by the power, I²R

And since they all have equal resistances, the only factor different that could result in more or less power is the current, I through the bulb.

Calculate the mass of air in a room 5m × 4m ×2m given that the density of air is 1.3kgm-²​
valentina_108 [34]

32.5 kg of air

Explanation:

To calculate the mass of the air, we use the density formula:

density = mass / volume

mass = density × volume

density of air = 1.3 kg/m³

volume = 5 × 3 × 2 = 25 m³

mass of the air = 1.3 kg/m³ × 25 m³

mass of the air = 32.5 kg
