The density is 4.76 gcm^-3
and if mass is in kg then density is equal to 4.76*10^-3
Answer:
Explanation:
Given that
Volume
As we know that
So
So we cab say that is equal to .
Answer:
Planets were like gods.
Explanation:
To the people of many ancient civilizations, the planets were thought to be deities. Our names for the planets are the Roman names for these deities. For example, Mars was the god of war and Venus the goddess of love.
We can conclude that as the mass on the right increases, the distance of the mass towards the right decreases. Also when the two masses balance, the net torque is zero.
<h3>What is torque</h3>
The torque experienced by an object a given position is the product of the applied force and the perpendicular distance of the object.
When 5 kg mass is at 2 m on the left, another 5 kg at 2 m on the right will balance it.
<h3>Position of 10 kg mass on the right</h3>
Apply principle of moment
<h3>Net torque</h3>
<h3>Position of the 20 kg mass</h3>
<h3>Net torque</h3>
Thus, we can conclude that as the mass on the right increases, the distance of the mass towards the right decreases. Also when the two masses balance, the net torque is zero.

Answer:
0 kgm/s
Explanation:
The momentum is the product of mass(m) and velocity(v).
Initially the velocity of truck is 0 m/s so the product of mass and velocity becomes 0.
It does not matter what is the weight of truck, because the velocity will make the product of m*v = 0
It does not matter what is the momentum of car.
