A steel block has a volume of 0.08 m³ and a density of 7,840 kg/m³. What is the force of gravity actingon the block (the weight) in water?
A. 5,362.56 N
B. 7,600.18 N
C. 6,700.56 N
D. 6,150.64 N

Answers

The mass of the block is

   (0.08 m³) x (7,840 kg/m³) = 627.2 kg.

The force of gravity on the block is

   (mass) x (gravity)

   = (627.2 kg) x (9.8 m/s²)

   =    6,146.6 newtons .

As long as the block is on Earth, that's its weight. In vacuum, in air,
in water, in sugar, in bed, in trouble, or in molasses ... that's the force
of gravity attracting it toward the center of the Earth.

If it happens to be in water, then there's another force acting on it ...
the upward force of buoyancy, equal to the weight of the water it
displaced.

The block displaced 0.08 m³ of water, so the buoyant force is the weight
of 0.08 m³ of water.

The density of water is 1,000 kg/m³, so the mass of the displaced
water is

    (0.08 m³) x (1,000 kg/m³) = 80 kg .

and its weight is (80 kg) x (9.8 m/s²) = 784 newtons.

That's the buoyant force on the block . . . 784 newtons.
It acts upward on the block, opposite to the force of gravity.
So, if there's a bathroom scale on the bottom of the pool,
and the block is resting on it, the scale will read

   (actual weight) minus (buoyant force)

   = (6,146.6 newtons) - (784 newtons) = 5,362.6 newtons .

The real weight of the block is 6146.6 newtons.
That's choice-D.

The apparent weight of the block in water is 5,362.6 newtons.
That's choice-A.

The question asked for the force of gravity on the block, and then
in parentheses it says (weight). Both of these are 6146.6 newtons.

If you answer 'D', and your answer is marked wrong and somebody
tries to tell you that the correct answer is 'A', then I want you to either
show them what I have written here, or else tell them to come see me,
and I will straighten them out.

Answer:The answer for PF students is D.

Explanation:

If the amplitude of the resultant wave is twice as great as the amplitude of either component wave, and this wave exhibits reinforcement, the component waves must A. be traveling in the opposite direction of the resultant wave.
B. have a different frequency than the resultant wave.
C. be in phase with each other.
D. have a different wavelength than the resultant wave.

Answers

The correct answer for the question that is being presented above is this one: "B. have a different frequency than the resultant wave." If the amplitude of the resultant wave is twice as great as the amplitude of either component wave, and this wave exhibits reinforcement, the component waves must have a different frequency than the resultant wave.

Correct answer choice is:

C. Be in phase with each other.

Explanation:

Components waves mix to produce a resultant with the equivalent wavelength but the amplitude which is bigger than the amplitude of both of the unique component waves, and this results in constructive interference, which states that the interference of two or more waves of identical frequency and phase, constructing in their respective reinforcement and constructing a single amplitude equivalent to the total of the amplitudes of the unique waves.

Briefly summarize how the pulleys worked with respect to changes in effort force and effort distance compared with resistance force and resistance distance what are the advantages of using pulleys what do you think would happen to the mechanical advantage if you needed a third movable pulley

Answers

A pulley is a wheel with two raised edges so that a rope or a string will run along the wheel. The effort force is the one where there is a weight attached to it and enables the pulley to work while the effort distance is the distance between the pulley and the weight attached.
