4 newtons, 4 amps, 4 joules, 4 watts, 4 ohms, 4 volts what does I=
1 answer:
Answer:
I amperes
Explanation:
Newton is the unit of force. Hence 4 newton is not the current “I”
Joules is the unit of energy and hence it do not signify current I
Watt is the unit of power i.e the rate of transfer of energy.
Ohm is the unit of resistance produces thereby obstructing the flow of current
And Volts is the unit of voltage or potential difference between two ends of an electric circuit. Thus, it is also does not signifies current.
Thus, I amperes

The weight of the meterstick is:
and this weight is applied at the center of mass of the meterstick, so at x=0.50 m, therefore at a distance
from the pivot.
The torque generated by the weight of the meterstick around the pivot is:
To keep the system in equilibrium, the mass of 0.50 kg must generate an equal torque with opposite direction of rotation, so it must be located at a distance d2 somewhere between x=0 and x=0.40 m. The magnitude of the torque should be the same, 0.20 Nm, and so we have:
from which we find the value of d2:
So, the mass should be put at x=-0.04 m from the pivot, therefore at the x=36 cm mark.
