Potential energy is what something has energy of staying still. if a car was the the top of a hill that’s where it has the most potential. kinetic energy is energy in motion. as that car on the hill starts to roll down, the potential of it lowers as the kinetic raises
Answer:
v₁ = 1 [m/s].
Explanation:
This problem can be solved by using the principle of conservation of linear momentum. Where momentum is conserved before and after catching the snowball.
![P=m*v](https://tex.z-dn.net/?f=P%3Dm%2Av)
where:
P = linear momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
![P=m*v\\P=5*10\\P=50[m/s]](https://tex.z-dn.net/?f=P%3Dm%2Av%5C%5CP%3D5%2A10%5C%5CP%3D50%5Bm%2Fs%5D)
As the momentum is conserved, it will be the same as that received by the person who catches the snowball.
![50= 50*v_{1}\\v_{1}=1[m/s]](https://tex.z-dn.net/?f=50%3D%2050%2Av_%7B1%7D%5C%5Cv_%7B1%7D%3D1%5Bm%2Fs%5D)
That is, the person who catches the snowball moves backwards with a speed of 1 [m/s].
Conductors are materials with many free electrons, so they allow electrical current to flow through them. Therefore, conductors are required in order to bring electricity to every room of the house.
Insulators, instead, are materials with few or no free electrons, so electrical currents do not flow through them. In the electrical wiring of the houses, they are used in order to isolate the conductive elements of the wire from other conductive materials (in fact, if the conductive elements touch other conductive elements of the house, part of the current would be dissipated)
Answer:
The volume of the balloon will increase when temperature rises, and the volume of the balloon decreases to its initial value as temperature cools down.
Explanation:
An inflated balloon contains a definite amount of gas. Since the temperature varies, its volume would vary with respect to temperature.
The increasing temperature causes an increase in the average kinetic energy of the molecules of the gas inside the balloon. Therefore, the volume of the balloon increases as the temperature rises.
As the temperature cools down, assuming that the balloon didn't burst in the process, the kinetic energy of the molecules of the gas decreases. So that the volume of the balloon decreases to its initial value.
Answer:
Renewable energy: Tidal, solar and wind
Non renewable energy: nuclear power
Explanation:
Renewable energy is any energy in which its source is always replenished or renewed.
While non renewable energy sources cannot be replenished or renewed immediately because of its limited availability of resources.
Most renewable energy sources are natural sources.
Solar, tidal and wind energy are renewable energy known as clean energy. While nuclear energy is a non renewable energy in which its source of energy is fuel ( uranium e.t.c)
