The rate of change of velocity per unit time is called acceleration.
Its SI unit is m/s².

Answer:
240N
Explanation:
The formula for force is F=mass×acceleration.
Therefore, Force= 120×2= 240N
Answer:
true
Explanation:
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
Answer:
30Km/h
Explanation:
acceleration is the change of speed in a given time so when we substract the accelerations we can know how much the car goes per an hour
Because many fuels are fossil fuels they take millions of years to form and the known reserves are being used much faster than the new ones being made
