Answer: Apply battery-terminal grease to the terminals to help prevent corrosion. It's available at any auto parts store and usually comes in a little ketchup-like packet. Another great option is AMSOIL Heavy-Duty Metal Protector. It creates a protective coating on terminals that wards off corrosion.
Explanation:
Answer:
D. 90 degrees.
Explanation:
Torque is a rotational force which moves an object in other direction. There should be 90 degrees out of phase to start, run winding currents with each other. Torque is produced by the rotational motion of an object. The angle of the object must be 90 degrees set in order to create torque.
Answer:
Temperature on the inside ofthe box
Explanation:
The power of the light bulb is the rate of heat conduction of the bulb, 
The thickness of the wall, L = 1.2 cm = 0.012m
Length of the cube's side, x = 20cm = 0.2 m
The area of the cubical box, A = 6x²
A = 6 * 0.2² = 6 * 0.04
A = 0.24 m²
Temperature of the surrounding, 
Temperature of the inside of the box, 
Coefficient of thermal conductivity, k = 0.8 W/m-K
The formula for the rate of heat conduction is given by:
Answer:
Technician A and B both are correct.
Explanation:
According to Technician A, we can stop noise by applying lubricant (Break friction).
According to Technician A, we can stop noise by set-up right position for break pad.
Answer:
T=kg·m^2/s^2
Explanation:
T = kg (m^2/s^2) m^3 /m^3
Here I wrote down the unit for every dimension.
T=kg m^2 / s^2
m^3 is divided between m^3, this is equal to 1.
Result: T=kg·m^2/s^2
PD: I'm not sure if this is what you ask for. I hope it helps
