Explanation:
Take a measuring cylinder and fill it with a certain amount of water. Measure this amount of water.
Place the paper clip in the filled measuring cylinder. You will notice that the water level has gone up. When we place the paper clip in the cylinder the volume of the paper clip gets added to the volume that was present in the cylinder.
The volume of the paper clip will be the final volume of water with the paper clip - The initial volume of water without the paper clip.
Any irregularly shaped object's volume can be determined by this method.
Answer:
1225 J
Explanation:
The Gravitational potential energy (PEG) gained by a mass lifted above the ground is given by
where
m is the mass
g = 9.8 m/s^2 is the acceleration due to gravity
h is the height at which the object has been lifted
In this problem, we have
m = 250 kg
h = 0.5 m
So, the PE of the object is
This information could be used in the following ways: the braking distance of a skidding car will depend on its initial speed and the coefficient of kinetic friction.
Thus, if the coefficient of friction is known the initial speed can be determined from the length of the skid marks.
What do you mean by Initial speed?
Initial speed can be described as how fast an object travels when gravity first applies force on the object. It can be represented in the form of (u) and is generally measured in metres per second (m/s).
It can be represented in three ways.
- v2=u2+2as
- v=u+at
- s=ut+0.5at2
Through these formulas we can calculate the initial speed of any object. It helps in understanding various velocities, time principles.

Answer: force from sun to mars = 
, force from mars to sun = 
Explanation: The force of attraction or repulsion between 2 object ( in this case the sun and mars ) in space is given by newton's law of gravitation which is given mathematically below as
where 
G = gravitational constant, 
= mass of mars, 
= mass of sun
the mars also exerts the same magnitude of force above on the sun but in the opposite direction, thus the force mars exerts on the sun is
