When you're using a crowbar to lift a large rock, you are working against the force called

\boxed {\bf Gravity}


\bf Explanation:
Gravity on Earth is what gives weight to all objects, it's defined as all things that have mass or energy are gravitated towards each other. Therefore when you're using a crowbar to lift a large rock, the weight is caused by gravity.


I hope this helps you!

A bucket is filled partly with water such that its combined mass is 2.5 kg. It is tied to a rope and whirled in a circle with a
Ivenika [448]

Answer:

1. Simply τ = m x g x r = 54kg x 9.8m/s² x 0.050m = 26 N·m

2. The bucket creates a torque

τ = 75kg x 9.8m/s² x 0.075m = 55 N·m,

so we must create the same torque with the handle.

55 N·m = F x 0.25m

F = 220 N

Explanation:

Hope this is helpful

What is the Voltage of a circuit that has a resistance of 50 and a current of 2 A?
Nutka1998 [239]

Answer:

It's actually 100V

Explanation:

To answer this, you'd need to use Ohm's law, which states that Voltage is equivalent to the product of Current and Resistance (V=IR).

V = 50 × 2

V = 100

Therefore the voltage is a 100V.

None of the answers you have listed match this though, so I'm guessing it either must be typo or the question itself is wrong.

Write some harms of friction.
Veseljchak [2.6K]

Answer:

Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects. Forest fires are caused due to the friction between tree branches. However, friction can also cause problems in a car. Friction between moving engine parts increases their temperature and causes the parts to wear down. Friction can be both harmful and helpful, so it may be necessary to decrease or increase friction.
