Kinetic energy is the energy associated with the motion of an object. It's a scalar quantity, there is no direction associated with KE and it has no components.
.
Therefore Kinetic energy is 817.96J.
<span>We put a motion detector at </span>one end of the track<span> and put a cart on the track. ... Next, we put a motorized fan on the cart and let it push the cart down the track. ... This is what I would expect based on the velocity graph, since </span>acceleration<span> equals the slope of the velocity graph, which remains</span>constant<span> in time.</span>
Answer:
A) True. Voltmeters measure voltages
C) True. They are placed in parallel
E) True ammeters are used to measure current
Explanation:
The devices for voltage measurement are the voltmeter and ammeter
Voltmeters have very high intense resistance and are placed in parallel
The ammeters have very small resist and are placed in series
Based on this establishment, let's analyze the statements
A) True. Voltmeters measure voltages
B) False has high intense resistance
C) True. They are placed in parallel
D) False ammeters are placed in series
E) True ammeters are used to measure current
F) False ammeters have a low internal resistance
Answer:
4 N
Explanation:
Electrostatic force is directly related to the charge of each object hence when the charge is doubled in only one of the objects, the force also double. If it's doubles on both objects, the force becomes four times. In this case, it's doubled on one object hence 2*2= 4 N
