Explanation:
string roller is called an example of wheel and axel because The thin rod which needs to be turned is called the axle and the wider object fixed to the axle, on which we apply force is called the wheel.
hence the we apply force on the roller and the string gets tight.
Answer:
The total resistance of the circuit = 188ohms
Explanation:
potential difference = 25volts
For resistors in series, equivalent resistance
Rt = R1 + R2 + R3
Rt = 120 + 18 + 50
Rt = 188ohms
The total resistance of the circuit = 188ohms
The things that a scientist should consider while observing
the force is the environmental conditions,the force that is expected to act on
the dam, the means to contain that force,
and compare different types of designs in accordance with the location
of the dam
The distance is 30 km and the displacement is 22.4 km North East
