Hi! I'm a few days late since I just saw this question just now, but I'll answer anyway.
Answer:
When an unbalanced force acts on a moving object, the velocity of the object will change. Change in velocity means a change in speed, direction, or both. For example, if you kick a soccer ball and it moves from one place to another, it means that unbalanced forces are acting upon it. The ball moves from one place to another after kicking it so the position changed.
Answer:
83816746.4254 m/s
Explanation:
m = Mass of electron = 
q = Charge of electron = 
V = Voltage = 
The kinetic energy of the electron is

Energy is given by

Balancing the energy

The velocity of the electrons is 83816746.4254 m/s
Answer:
hi there i need the answer nowwwwwwww
Explanation:
NONE
Answer:
<h2>89,460 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 8.52 × 10,500
We have the final answer as
<h3>89,460 g</h3>
Hope this helps you
