Answer:If a 5-kilogram mass is raised vertically 2 meters from the surface of the Earth, its gain in potential energy is approximately 1) 0 J 2) 10 J 3) 20 J 4) 100 J 43.
Explanation:
When the average kinetic energy of the molecules go up ( a rise in temperature) the average speed of the molecules increases, the molecules now on average have more kinetic energy .
Answer:
Multiply the resistances. Example: Two resistors in parallel, 100 and 200 ohms. 100 x 200 = 20,000
Add the resistances. Example: 100 + 200 = 300
Divide the result in Step 1 by the result in Step 2. This gives you the total resistance. Example: 20,000 / 300 = 66.7 ohms.

Answer: The perpendicular force to be used to tighten the bolt is
F=347.8N
Explanation:
Mathematically the torque is expressed as
T=F*L
Where T= torque in Nm
F= force in N
And L = perpendicular distance
Now given
T=63.3Nm
L=18.2cm to meter 18.2/100
0.182m
F=?
Making F the subject of the formula in our equation
F=T/L
F=63.3/0.182
F=347.8N
What is torque?
Torque is the product of force and perpendicular distance of the line of action.
