Answer:
923.44N
Explanation:
Obviously Fn cannot equal Fg since the elevator is moving up
Where Fn is the force read on the scale
Fg is gravitational force=mg=77.6 x 9.8=760.48N
So we use this equation:
Fnet = Fn - Fg
ma = Fn - mg
77.6 x 2.1 = Fn – 760.48
162.96N = Fn – 760.48N
923.44 N = Fn
The answer is 923.44 N
The answer is D
The body of water contains more molecules; more molecules, more kinetic energy, which creates thermal energy.
The molecules are moving faster is the coffee, so the temperature is higher.
Answer:
3/5 v
Explanation:
The computation of speed will the alpha particle have after the collision is shown below:-
In a perfectly elastic the kinetic energy and collision the momentum are considered.
The velocity of the particles defines the below equation:
As we know that
Here, we consider A is the alpha particle and B is the proton and now by the above values we can solve the equation which is below:-
Therefore the correct answer is 
Answer:
a force and a movement in the same direction as the force.
