Answer:
d. The hammer falls with a constant acceleration
Explanation:
Since gravity is the only thing that is acting on the hammer as it falls and gravity is a form of acceleration then acceleration of 9.81m/s² which is gravity is the correct answer.
Answer:
b)
movement creates a difference in air pressure.
as warm air rises up it creates a vaccum so due to that the pressure in that region decreases.
Any metal element can form a positive ion because they lose electrons to become stabilized
Newton’s second law is that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
