According to the formula of KE.
KE = 1/2m • v^2.
Both of the variables of mass and energy m determines an object's kinetic energy. Assuming the mass of an object is held constant, the change in velocity, or velocity change will dictate the amount of kinetic energy that a particular object posses.
Answer:
Determine the mass of substance and it's molar mass. Divide the given mass by it's molar mass to get moles and multiply time
6.002*1023 molecules 1mole
A monkey needs to use more force and strength than a bat when swinging and they can get more momentum to push forward. and bat needs shorter limbs so they don’t have much weight to carry when they are flapping their wings. they will go faster with less mass in their arms.
