A 10-Newton object displaces 12 Newtons of water. Will this object sink of float?I'm confused, my guess is sink.

Answers

Answer: The object will float.

Explanation:

Balanced force is defined as the force that gets cancelled out when equal forces are acting in the opposite direction. The net force on the system comes out to be 0.

Unbalanced force is defined as the force that does not get cancelled out because unequal forces act on the system in opposite direction. The motion of the object is in the direction of net force.

According to the question:

Object is exerting a downward force of 10 N on the water and water is exerting an upward force of 12 N on water.

As, the upward force by water is more than the downward force by object. So, the object will float on the surface of water.

If the downward force by the object is been more than the upward force, the object will sink.

Hence, the object will float.
This object would float

If I'm doing a project for school about a simple machines and I got a wheel and axle, how does the thing work ?!?!?

Answers

The wheel and axle is a simple machine consisting of a circular object called a wheel and a shaft known as an axle, which is attached to the wheel. All simple machines change the amount of effort needed to work and are the basis for all other machines, according to Mediahex. Two examples of a wheel and axle are a doorknob and a round water facet. In a doorknob, a larger handle turns a much smaller axle to move the door latch. In addition, a faucet has a larger handle that turns a much smaller axle to open a water valve. Another example of a wheel and axle is a car steering wheel, where the driver exerts a force on the outer edge of the wheel to cause the front wheels to turn..
