'Gram', 'kilogram', and 'metric ton' are units of mass, not weight.
'Pound' can be either a unit of mass or of force. Most people
use it most of the time to mean weight.
Answer:
The turning effect of a force is known as the moment. It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn. When undoing a nut fastened to a screw by hand one realises that the amount of force required is a lot greater than when undoing the same nut using a spanner.
Explanation:
Answer:
V = 0.0392 volt
Explanation:
given that the
Current I = 0.7 mA
Resistance R = 56 Ohms
According to Ohm's law,
V = IR
Where V is the Voltage in the circuit.
Substitute I and R into the formula
V = 0.7 ×10^-3 × 56
V = 0.0392 volt
The ammeter can be use to read current in a circuit when it is connected to the device in which the resistors are connected in series.
While for the Voltmeter, the resistors are connected in parallel.
<span>the body is moving horizontally, it doesnt matter watever kind of horizontal forces are acting.
Therefore the normal force is equal to the weight
N=mg=4.2*9.8=41N
Note: the other data in the problem have no relevance
answer
</span> the normal force on the sled is 41N
Need Height and Mass, since Gravitational Potential Energy is equal to mgh. Not really sure what you’re asking though. Please elaborate and I can give a better answer!
