Answer:
0.2m/s2
Explanation:
acceleration= change in velocity ( in this case speed)/ change in time.
4.5-3.5=1m/s
change in time=5-0 =5
1m/s divided by 5 seconds acceleration as the result
Temperature lower than absolute zero is not possible. Lower than absolute zero a gas contain negative pressure and volume which is not possible. temperature is the energy created by moving atoms absolute zero is a complete stand still you can make particles move to the end of the universe but the coldest temperature will be stuck at the point where atoms are motionless
hope that helped :)
The answer is c. skill of the balls exert a gravitational force because they all have mass.
Ek = 6KJ.
In physics, the kinetic energy of a body or object is the one that owns due to its movement and is given by the equation , where m is the mass of the object in kilograms and v is the velocity in m/s.
An object that it has a mass of 30 kilograms and moves with a velocity of 20m/s, its kinetic energy is given by:
