Answer:
Actual answers are: Renewable energy supplies may not be completely reliable and It is difficult to generate electricity in large quantities using renewable resources.
Explanation:
cation
anion is negatively charged, so more electrons then protons,
cation is positively charged, so more protons thatn electrons
Answer:
60 m
Explanation:
Arthur and Betty will be walking for the same amount of time t
Speed of Arthur = 3 m/s
Speed of Betty = 2 m/s
Distance = Speed × time
Distance covered by Arthur = 3t
Distance covered by Betty = 2t
Distance that Arthur and Betty will cover will be 100 m
3t+2t = 100
⇒5t = 100
⇒t = 100/5
⇒t = 20 s
So, Arthur and Betty will be walking for 20 seconds
Spot is by Arthur's side and keeps running in between them until they meet. So, Spot will be running for 20 seconds and the displacement covered will be the distance covered by Arthur which is
3t = 3×20 = 60m
Displacement is the shortest distance between two points so, Spot's displacement will be 60 m
The box accelerates at 1. 0 m/s² to the right because the net force is 17N to the right . This statement clearly depicts the relation between force and acceleration. Hence option A is correct.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec².It is a vector quantity. It requires both magnitudes as well as direction to define.
According to Newton's second law of motion, the net force acting on the body is equal to the product of mass and acceleration of the body.
The direction of acceleration is in the direction of net force acted.
Hence option A is correct.

The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting.
