Which is A child weighing 20 kg sitting inside a car of mass 1000 kg moves with a velocity of 10 m s What is the momentum of the child?

-- "20 kg" is the child's mass, not her weight.
-- The car's mass doesn't matter.
The child's momentum is (M V) = (20) (10) = 200 kilogram-meters per second.

How do slip off slopes form?
When alluvium is deposited on the inside of meanders. It is deposited because velocity is slower there
Can You calculate the velocity of a fart?
Generally wind speed is measured using a cup anemometer (wind speed measuring device). The velocity of a flatulation will decrease as it leaves the anus, so to properly measure the velocity the measurement would have to be done before the exit. Theoretically you could measure the velocity of the gases by placing a miniature cup anemometer with walls inside the rectal tract close to the anus to give an approximate wind speed (velocity) of the gases.
What is a synonym for inside?
the answer for inside is interior
Does area mean outside or inside?
inside
Should a question mark be inside bracket or outside?
Inside if the sentence inside the brackets is a question.
Which is A child weighing 20 kg sitting inside a car of mass 1000 kg moves with a velocity of 10 m s What is the total momentum of the child and the car together?
Use the momentum equation! ∑M * V = (20 + 1000)(10) = 10,200
How do the mass and velocity of a moving object affects its momentum?
As the velocity decreases, the momentum increases. Mass is the matter inside of something and momentum is how hard it is to stop something. Therefore momentum needs mass to function because without mass there would be no momentum. So think of the sentence above like this: velocity ( a measure of momentum) decreases, the momentum (including mass inside an object) goes up therefore making the mass increase while the velocity decreases.
Define the conservation of momentum?
the principle that the total linear momentum in a closed system is constant and is not affected by processes occurring inside the system.
Can sitting inside a running car with windows closed harm you?
sitting in a running car with windows closed is any fumes released inside of car.
A molecule inside a cell consists of 3500 covalently linked atoms weighing about 105000 daltons?
A macromolecule
Which side of the stream is shallower the inside curve or outside?
Since the outside curve has a higher velocity, it has more erosion meaning the inside curve has a slower velocity more deposition causing it to be shallower. The outside curve is deep.
Dimension of angular momentum?
case 1 is mass (m) on weightless length (r) of string at constant velocity (v), so angular momentum L = r * (m * v), SI units are n.m.s. or kg.m^2.s^-1 . case 2 is mass(m) rotating around an axis inside its own mass ie solid sphere rotating about its fixed symmetry axis, angular momentum L = I * w, where I is the mass moment of inertia of the sphere about its fixed symettry axis, and w is the rotation in radians per second, units are kg.m^2 for I, and rad / sec for w
How do you measure instantaneous velocity?
You can transform linear velocity into rotational velocity with a rolling wheel. Rotational velocity can be measured inside a gravity field because of generated centrifugal force. When you suspend your arms freely while rotating, the angle between your body and your arm is a measure for the rotational speed.
