Answer: The correct answer is balanced force.
Explanation:
Balanced forces are balanced when the forces are acting equal in magnitude but opposite in direction. The balanced forces will not cause change in the speed of the object.
Unbalanced forces are unbalanced when the forces acting on the object are not equal in magnitude. The combined force is the difference between the forces. It will cause the change in the speed of the body.
Therefore, forces that are equal in size but opposite in direction are balanced.
The weight of anything is (mass) x (gravity in the place where the thing is).
Gravity on Earth is about 9.8 newtons per kilogram, so on Earth,
the weight of the book is
(2.06 kg) x (9.8 N/kg) = <em>20.19 newtons</em> .
Another way to get around it is:
On Earth, 1 kg of mass weighs about 2.205 pounds, so on earth,
the weight of the book is
(2.06 kg) x (2.205 pounds/kg) = <em>4.54 pounds </em>.
Did you try googling it lol thats what i do if its a problem like that. sometimes there are websites that answer it you just have to look really hard
Answer:
Explanation:
<u>Given:</u>
Mass = m = 200,000 kg
Vertical Distance = h = 120 m
Speed = v = 14 m/s
Acceleration due to gravity = g = 10 m/s²
<u>Required:</u>
1) Gravitational Potential Energy = P.E = ?
2) Kinetic Energy = K.E. = ?
<u>Formula:</u>
1) P.E. = mgh
2) K.E. = 
<u>Solution:</u>
1) P.E. = (200,000)(10)(120)
P.E. = 240,000,000 Joules
P.E. = 240 Mega Joules
P.E. = 240 MJ
2) K.E. = 1/2 (200000)(14)^2
K.E. = (100000)(196)
K.E. = 19,600,000 Joules
K.E. = 19.6 MJ
