The weight of a body floating in a liquid is

Answers

Answer 1

Answer:

Answer:

The apparent weight is the weight of the body minus the weight of the liquid displaced. The body will float only when both the weights are same. In this case, the given body of weight W is floating and hence the apparent weight is zero.

Answer 2

Answer:

Answer:

Zero

A photon with a wavelength of 2.29 × 10^–7 meter strikes a mercury atom in the ground state.Based on your answer to question 79, state if this photon can be absorbed by the mercury atom.
Explain your answer.

Answers

The photon can be absorbed and the energy of the photon is exactly equal to the energy-level difference between the ground state and the level d.

Train is traveling at an initial velocity of 68.325m/s. After 23.75 seconds it speeds up to a final velocity of 79.32m/s. What is the train's acceleration during this time

Answers

So,

We know that:
$acceleration = ( final\ velocity\ -\ initial\ velocity)/(time)$

Plug in the values.
$acceleration = (79.32 m/s^(2)\ -\ 68.325m/s^(2))/(23.75 secs)$
$acceleration = (10.995m/s^(2) )/(23.75 secs)$
$acceleration = 0.4629 m/s^(2)$

Brody and Ethel are arguing about waves. Brody says that waving his hand back and forth is a scientific wave. Ethel says that it is not. Which statement best describes who is correct?-Brody is correct because the wave involves an input of energy.
-Ethel is correct because energy is not carried from one place to another.
-Brody is correct because the pattern repeats.

Why does a moving object come to a stop on a frictional surface? a.The object’s kinetic energy is transformed into mainly heat energy. b.The object’s potential energy is transformed into mainly kinetic energy. c.The object loses all its energy in deformation. d.The object’s kinetic energy is transformed into mainly potential energy.

Answers

The correct answer to the question is - A) Object's kinetic energy is transformed into mainly heat energy.

EXPLANATION:

The friction is the opposing force which acts tangentially between two surfaces when there is a relative velocity between them.

As per the question, the moving object comes to rest after the application of frictional force.

Initially the object is in motion.Hence, the energy possessed by the moving object is kinetic energy.

When frictional force is applied on the moving object, the kinetic energy of the moving object will be converted into mainly heat energy. It is due to the fact that friction causes heat production between two surfaces in contact.

Hence, correct option will be that the object's kinetic energy is transformed into mainly heat energy.

A) the objects kinetic energy is transformed into mainly heat energy

That "heat energy" is called fricton
