Most likely B. Will erode, if not it will grow weeds
IF that were true, then you could take some of the work from the output,
put it back into the input to keep the machine running, and use the rest
to run the lights and the hot water heater in your house. That way, you'd
never need to buy energy from the electric company.
You NEVER get more work out of a machine than you put into it.
Never never never.
(Unless there's a battery or a tiny gasoline engine or a hamster
on a treadmill inside.)
Answer:
1398.12 N
Explanation:
We define the x-axis in the direction parallel to the movement of the truck on and the y-axis in the direction perpendicular to it.
x-components of the ropes forces
T₁x = 615N*cos31°=527.1579 N :Tension in direction x of the rope of the car 1
T₂x= 961 N*cos25°=870.96 N :Tension in direction x of the rope of the car 2
Net forward force exerted on the truck in the direction it is headed (Fnx)
Fnx = T₁x + T₂x
Fnx = 527.1579 N + 870.96 N
Fnx = 1398.12 N
Answer:
The temperature of the coil will increase (over heating will occur)
Explanation:
This overheating generally occurs when the motor is overloaded, when a bearing seizes up, when something locks the motor shaft and prevents it from turning, or when the motor simply fails to start properly.
Back emf is zero when the motor is not turning, and it increases proportionally to the motor's angular velocity. As the motor turns faster and faster, the back emf grows, always opposing the driving emf, and reduces the voltage across the coil and the amount of current it draws.
Answer:
False.
Explanation:
Up regulation involves the increase of receptors and it makes the cells more sensitive to the hormones.It's the down regulation that involves the loss of receptors and prevents the target cells from overreacting to persistently high hormone levels.
