The answer is that FRICTION PRODUCES HEAT.
Answer:
1.147 %
Explanation:
= Density of mercury = 
g = Acceleration due to gravity = 9.81 m/s²
h = Height of mercury = 8.69 m
Standard atmospheric pressure = 
6.55 mmHg converting to Pa
Dividing air pressure by the above value
The fraction of atmospheric pressure is 1.147 %
Answer:
The reason why first impressions are so important is that they last well beyond that moment. This is thanks to something called the primacy effect, which means that when someone experiences something before other things in a sequence, they remember that first thing more.
It’s not true! Due to the earth already moving around earth it’s not possible for earth to meet the Apple so instead the Apple meets earth due to the gravitational pole! If earth met the Apple it would mess up circling the sun causing us to meet out demise

Answer:
1620000J
Explanation:
Given parameters:
Resistance = 24ohm
Current = 5A
Time = 45min
Unknown:
Work done = ?
Solution:
Electrical work done is given as the product of power with time;
Electrical work done = power x time
Power = I²R
Electrical work done = I²R x time
Convert the given time to seconds;
1min = 60s
45 min = 45 x 60 = 2700s
Now,
Work done = 5² x 24 x 2700 = 1620000J
