One disadvantage<span> with </span>renewable energy<span> is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators
One advantage</span><span> with renewable energy is that as it is renewable it is therefore sustainable and so will never run out.
I dont know who you are referring to as "rosa" i hope this helps

Answer:
5.37 m/s
0.98 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
Velocity of the ball when it passes an observer sitting at a window is 5.37 m/s
Time taken by the ball to pass the observer sitting at a window is 0.98 seconds
It's a normal force exerted by the floor. It balances the gravitational force. Option A is correct. The normal force is balanced by the gravitational force.
<h3>What is the friction force?</h3>
It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N). Mathematically it is defined as the product of the coefficient of friction and normal reaction.
On resolving the given force and accelertaion in the different components and balancing the equation gets components in the y-direction.
The normal force is balanced by the gravitational force. It's a normal force exerted by the floor. It balances the gravitational force.
Hence, option A is correct.

Metals are good conductors of heat, which is important for cooking (both heating and cooling occurs rapidly
Answer:The actual answer is heat.
Explanation:There is always water under a forming hurricane, the strength of the hurricane depends on the heat of the water since heat is a raw form of energy. It can transfer to the storm.
