The energy transferred by the appliance using mains electricity is 17.3 KJ
<h3>Data obtained from the question </h3>
- Potential difference (V) = 230V
- Charge (Q) = 150 C
<h3>How to determine the energy transferred </h3>
The energy transferred can be obtained as follow:
E = ½QV
E = ½ × 150 × 230
E = 75 × 230
E = 17250 J
Divide by 1000 to express in kilojoules
E = 17250 / 1000
E = 17.3 KJ

Answer:
<em>The grapefruit dropped 2.54 m and hit the ground at 7.06 m/s</em>
Explanation:
<u>Free Fall Motion
</u>
A free-falling object falls under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. Free-falling objects do not encounter air resistance.
If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is 
The final velocity of a free-falling object after a time t is given by:
vf=g.t
The distance traveled by a dropped object is:

Given a grapefruit free falls from a tree and hits the ground t=0.72 s later, we can calculate the height it fell from:

y = 2.54 m
The final speed is computed below:

vf = 7.06 m/s
The grapefruit dropped 2.54 m and hit the ground at 7.06 m/s
The answer is B,
because it is more round and lower than the other mountains.
The steeper and more pointy and higher a mountain is, the older it is.
Hope this helps!
