The correct answer is:

An apple falling from a tree is transitional kinetic energy

Explanation:

The energy of motion of a body, according to the work it would do if it were produced to rest. The translational kinetic energy depends on motion through space, and for a determined body of regular mass is equal to the output of half the mass times the intersection of the speed. and translational (the energy due to a motion from one position to another.

Answer: Option (e) is the correct answer.

Explanation:

There are three types of kinetic energy which are vibrational, rotational and translational kinetic energy.

A plucked string on a guitar will produce sound and it represents vibrational kinetic energy.

The moving blades of a ceiling fan shows the rotation of blades and it represents rotational kinetic energy.

A spinning top also displays rotation therefore, it represents rotational kinetic energy.

A tuning fork struck on a rubber block will produce sound and it will vibrate. Therefore, it represents vibrational kinetic energy.

An apple falling from a tree shows that apple is linearly falls on the ground therefore, it represents translational kinetic energy.

Thus, we can conclude that an apple falling from a tree is the best example which represents translational kinetic energy.

A 140 kg load is attached to a crane, which moves the load vertically. Calculate the tension in the

Nesterboy [21]

Answer:

A.) 1372 N

B.) 1316 N

C.) 1428 N

Explanation:

Given that a 140 kg load is attached to a crane, which moves the load vertically. Calculate the tension in the cable for the following cases:

a. The load moves downward at a constant velocity

At constant velocity, acceleration = 0

T - mg = ma

T - mg = 0

T = mg

T = 140 × 9.8

T = 1372N

b. The load accelerates downward at a rate 0.4 m/s??

Mg - T = ma

140 × 9.8 - T = 140 × 0.4

1372 - T = 56

-T = 56 - 1372

- T = - 1316

T = 1316N

C. The load accelerates upward at a rate 0.4 m/s??

T - mg = ma

T - 140 × 9.8 = 140 × 0.4

T - 1372 = 56

T = 56 + 1372

T = 1428N

If the SAME person does a cannonball from these different heights, which height will produce the biggest SPLASH? WHY?

sveta [45]

Answer:

the impact on the water varies from different heights, therefore the mass stays the same, yet the force on the water increases from a higher height. A taller height will produce a bigger splash!

If Earth orbited the Sun in 9 months instead of 12, then, compared with a sidereal day, a solar day would be

Tcecarenko [31]

Answer:

longer

Explanation:

The relationship between the solar day and sidereal is as follows:

The length of the sidereal day is

= (Solar day) (solar year ÷ solar year + 1 day)

As it can be seen that the day i.e. solar its length would be greater as compared with the sidereal day.

In the case when the earn orbited the sun in 9 months rather than 12 so here the sidereal day would be the similar but the solar day would be longer as compared with the original one

Which of the following values represents an index of refraction of an actual material?

serg [7]

Sadly, we're forced to answer the question without the benefit of the
list of choices, which, for some reason, you decided not to let us see.

Index of refraction of a substance =

(speed of light in vacuum) / (speed of light in the substance).

Any number greater than ' 1 ' can be an index of refraction. A number
less than ' 1 ' can't be . . . that would be saying that the speed of light
in this substance is greater than the speed of light in vacuum.
