Answer:
Gpe = 15680 Joules
Explanation:
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
G.P.E = mgh
Where;
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Given the following data;
Mass = 20 kg
Height = 80 m
We know that acceleration due to gravity is equal to 9.8 m/s²
To find the gravitational potential energy;
Gpe = mgh
Gpe = 20 * 80 * 9.8
Gpe = 15680 Joules
Pig because it is made up of many organs system like cardiovascular and muscular system
Answer:
0.02
Explanation:
Force,
where N is normal reaction and coefficient of kinetic friction is
. Also, N is equivalent to mg ie N=mg where m is mass of an object and g is acceleration due to gravity. Making
the subject of the formula then

Substituting F with 2 N, m with 10 kg and g with 9.81 then

Answer:
Tar
Explanation: Tar is a big ingredient in cigarettes and can cause the sticky substance
I think the answer is C. The speed increases. I hope this helps. I'm sorry if I'm wrong :)
