Answer:
The standard acceleration due to gravity (or standard acceleration of free fall), sometimes abbreviated as standard gravity, usually denoted by ɡ0 or ɡn, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is defined by standard as 9.80665 m/s2 (about 32.17405 ft/s2).
Explanation:
The tension does no (zero) work
F· S = W
Since the tension is perpendicular to the direction of motion, and there is no change in S the work done is zero.
Answer:
The role of a commutator in a electric generator is a rotary switch (in certain types of electrical generators that periodically reverse the current direction between the rotor and the external circuit by that reversing it in the current direction teb rotating windings all half turn a force called torque is produced)
Answer:
The independent variable is plotted on the x-axis. This is the variable that is being manipulated or controlled.
Answer:
The magnitude of the electric field strength = 7.2 x 10⁸ N/C
Explanation:
The linear density:
Point r = 3 cm = 3/100 m
r = 0.03 m
The electric field strength is calculated below
The magnitude of the electric field strength = 7.2 x 10⁸ N/C
