Answer:
The silicon used to make monocrystalline solar cells has a high level of purity. ... Because of the way light interacts with a monocrystalline silicon layer, monocrystalline solar panels appear black in color.
Answer:
Only a backward force is acting, no forward force.
Explanation:
- Once released from the initial push, in absence of friction, the shopping cart would continue moving forward at a constant speed forever.
- As it would move at a constant speed, no net force would be acting on it.
- So, if it is gradually slowing, there must be a net force producing an acceleration in a direction opposite to the movement.
- This force is the kinetic friction force, and is the only force acting on the cart in the horizontal direction.
- As any friction force, opposes to the relative movement between the cart and the horizontal floor, which means that is directed backward.
- This is consistent with the direction of the acceleration of the cart.
Answer:
Explanation:
We are given that
Gravitational force=
r=0,U(0)=0
We know that
Gravitational potential energy=
Substitute r=0 ,U(0)=0
Substitute the value
Rest - it is the state in which body doesn’t move from it’s place
motion - it is the state in which body moves from it’s place
Ok so I already studied this and I realized it was water or also Oxygen
