Answer: Boat P

Explanation:

Multiple all of them mass times acceleration and which ever one was the greatest was the answer. Which was Boat P 0.2436

The minimum time taken to unwind the rubberband is by boat P.

The highest amount of force to unwind the rubberband is generated by boat P.

The table shows all the mass, acceleration and time of each boat. To unwind the rubber band, the required force can be calculated as given below.

Force = Mass [tex]\times[/tex] Acceleration

For boat N, force is [tex]f_n = 0.125\times 1.6 = 0.2 \;\rm N[/tex]

For boat P, force is [tex]f_p = 0.116\times 2.1 = 0.24 \;\rm N[/tex]

For boat Q, force is [tex]f_q = 0.130\times 1.0 = 0.13 \;\rm N[/tex]

For boat R, force is [tex]f_r = 0.118\times 1.8 = 0.21 \;\rm N[/tex]

Hence we can conclude that the highest amount of force to unwind the rubberband is generated by boat P.

Answer:

[tex]d=7970\ kg/m^3[/tex]

Explanation:

Given that,

The density of iron is 7.97 g/cm³.

We need to find the density in SI unit. The SI unit of density is kg/m³.

We know that,

1 kg = 1000 g

1 m = 100 cm

So,

[tex]7.97\ g/cm^3=7.97 \times \dfrac{(\dfrac{1}{1000})\ kg}{(\dfrac{1}{100}^3)\ m^3}\\\\=7970\ kg/m^3[/tex]

So, the density of the iron is [tex]7970\ kg/m^3[/tex].

Answer:

Input work is the work done on a machine as the input force acts through the input distance. This is in contrast to output work which is a force that is applied by the body or system to something else. Output work is the work done by a machine as the output force acts through the output distance, hope that helped

Answer:

All music in the world, is form only two notes and those notes are described below in detailed explanation.

Explanation:

In the chromatic scale, there are basically seven central musical notes, designated A, B, C, D, E, F, and G. They individual express a separate pitch or frequency. For illustration, the "central" A note has a pitch of 450 Hz, and the "common" B note has a pitch of 495 Hz.

Varieties Of Musical Notes You Require To Understand

Semibreve (Whole Note)

Minim (Half Note)

Crotchet (Quarter Note)

All music, listened to in the world, is from only twelve (12) notes.

A music can be defined as the systematic combination of an instrumental sound and human vocals, in order to produce harmonious tunes or sounds.

A note can be defined as a symbol which is used to denote a musical sound with respect to its pitch and duration.

Basically, all the music that are available and listened to in the world are typically produced from only twelve (12) notes.

This ultimately implies that, any musical piece that you may have come across in this world comprises only twelve (12) notes and these include:

Answer:

The direction of these oscillations is the difference between longitudinal or transverse waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. In transverse waves, the vibrations are at right angles to the direction of wave travel.

Explanation:

The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

A sound wave is the wave that shows the disturbance patterns that should be lead by the movement of the energy that should be travelled via the medium like air, water, since it should be propagated away from the sound source.

Therefore, The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

Moonlight; phases; eight; 29 days; sunlit; earth; sun; moon.

Explanation:

A moon generally do not have or possess light but rather it reflects the light from the sun.

The moon is lit by light bouncing off of it. That light reaches Earth as moonlight. The different shapes that the moon appears to have are called phases. The moon goes through eight (8) phases as it revolves around the earth every 29 days. The phase that we see depends on how much of the sunlit part of the moon we can see. This depends on the positions of the earth, sun, and moon.

The eight (8) phases of the moon include the following;

1. Last quarter half moon.

2. Waning crescent moon.

3. New moon.

4. Waxing crescent moon.

5. First quarter half moon.

6. Waxing Gibbous moon.

7. Full moon.

8. Waning Gibbous moon.

Answer:

2900 N

Explanation:

We are given;

Magnetic flux density; B = 3.6 × 10² T

Length of wire; L = 19 m

Current; I = 0.043 A

Formula for force in this regards is;

F = BIL

Where;

B is Magnetic flux density

I is current

L is length

Thus;

F = 3.6 × 10² × 0.043 × 19

F = 2941.2

To 2 significant figures gives;

F = 2900 N

Answer:

1. The ice molecules are at a temperature of 0°C;

2. The ice molecules are absorbing latent heat which would result in their turning to liquid water. Therefore, melting or fusion is occurring.

Note: The question did not provide any options to choose from.

Explanation:

The process of change of state occurs when heat is added or removed from a substance. For example, solid may change to a liquid when heat is added to it whereas a liquid may change to liquid when heat is removed from it.

During the process of change of state, the temperature of the substance undergoing a change of state does not change throughout the time it is undergoing the change. The temperature will begin to increase or decrease when all the molecules of the substance has undergone a change of state. The heat supplied to or removed from a substance during a change of state is known as latent heat.

When a solid changes to liquid, it is known as fusion and the heat absorbed by the solid substance is known as latent heat heat of fusion. If a liquid changes to gas, it is known as vaporization and the heat absorbed by the liquid is known as latent heat of vaporization.

In the experiment by the students above, since the temperature of the ice remains constant at 0°C when heat is supplied from the Bunsen burner to it, the following processes could be occurring:

Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not.

Ultraviolet Rays in the electromagnetic Spectrum Ultraviolet rays are a kind of electromagnetic radiation that extends from the visible light spectrum to the X-ray area.

Harmful rays have a long-term effect on humans, causing skin and eye problems. It is also a source of Vitamin C.

Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not,

Hence light from the ultraviolet flashlight harden the filling when light from the lamp does not.
