If a 70kg man and a 40k boy are both running at the same velocity, who has more momentum?

Physics
1 answer:
arlik [135]3 years ago
3 0

Answer:

70 kg man

Explanation:

Let their velocities be v

Mass of the man= 70 kg

Hence, momentum of the man= 70v

Mass of the boy= 40 kg

Hence, momentum of the boy= 40v

70v > 40v

Clearly the momentum of the man is greater than that of the boy.

Scientists have been able to estimate the age of our solar system by dating _____
Alisiya [41]

Answer: The correct answer is "radiometric dating".

Explanation:

Radiometric dating: It is a technique which is used to estimate the age of the rocks. In this technique, there is neither daughter product or parent nuclide can leave or enter the material after its formation.

Radioactive atoms are unstable. It decays into stable daughter atom.

Firstly, measure the quantity of the unstable atoms which are left in rock. Then, compare remaining the quantity of the unstable atoms with the quantity of stable daughter atoms in the rock to calculate the passed time since that rock formed.

Therefore, Scientists have been able to estimate the age of our solar system by radiometric dating.

What is the relationship between the center of gravity and the support base for an object that is in stable equilibrium?
Norma-Jean [14]

Answer:

when the center of gravity is within the washing area, the torque returns in the body to its initial position and is in a stable equilibrium

Explanation:

The concept of center of gravity is equivalent to the concept of center of mass, in this place all external forces applied can be considered.

When we analyze the balance of a body that is the torque it is the one that defines the balance

      τ = F xd

If the torque tends to restore the body to the initial position the balance is stable, but if the torque has to increase the body's rotation the balance is unstable

. When the body tends to rotate the torque with respect to the pivot point at the base it decreases because the distance from the center of gravity to the end of the base decreases in value, but it has to return it to the initial position, the balance is stable. The critical point of this process is when the center of gravity is at the limit of the body base area in this case the torque is zero; If the body rotates a little more the center of gravity is outside the base, the torque changes sign and has to increase the turn, going to an unstable balance.

In summary, when the center of gravity is within the washing area, the torque returns in the body to its initial position and is in a stable equilibrium.
