Answer:
Explanation:
Velocity can be found using the following formula:
where p is the momentum and m is the mass.
The woman has a mass of 55 kilograms and a momentum of 200 kilogram meters per second.
Substitute the values into the formula.
Divide. Note that the kilograms, or kg, will cancel each other out.
The woman's velocity is 3.63636364 meters per second.
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body.
Metals are good conductors because the molecules that are inside the metal are tightly packed together. This is why the heat moves through the metal quickly.
Answer: See answers below.
Explanation: In this problem, we must be clear about the concept of weight. Weight is defined as the product of mass by gravitational acceleration.
We must be clear that the mass is always preserved, that is, the mass of 15 [kg] will always be the same regardless of the planet where they are.
where:
W = weight [N] (units of Newtons)
m = mass = 15 [kg]
g = gravity acceleration [m/s²]
Since we have 9 places with different gravitational acceleration, then we calculate the weight in each of these nine places.
Mercury
Venus
Moon
Mars
Jupiter
Saturn
Uranus
Neptune
Pluto
