Answer:
270Joues
Explanation:
Step one:
given data
Force F= 45N
distance moved d= 6m
Required
The work done in moving the block 6m
Step two:
We know that the expression for the work done is
WD= force* distance
WD= 45*6
WD=270Joues
Answer:
73N
Explanation:Just multiply 1.2^2 by 50
Answer: A
Explanation: isotopes of the same thing element have the same number of protons in the nucleus but differ in the number of neutrons.
Answer:
An object's acceleration depends on its mass and on the net force acting on it.
Explanation:
Newton's second law states 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.
