Answer:

The force used

Explanation:

This has to be because of the force used. Both Susie and her younger brother might have hit the ball with the same velocity, but they surely couldn't have hit it with the same force. The force with which Susie hurts it is heavier than that with which her younger brother hits it, and as such, Susie gets to fall down more pins than her brother will be able to. The ball has to have a lot of force in it for it to be able to knock off all the pins there. So basically, the more the force, the higher it's chances of hitting all the pins

Explanation:

Answer:

Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth's land would be habitable.

Ocean currents help to regulate the climate of the earth as it transports warm water  from the equator to the polar region and carry cold water from poles back towards the equator .

An ocean current is a continuous , directed movement of sea water generated because wind , breaking waves , temperature , salinity differences etc .

Ocean currents that move from north to south ,transports warm water  from the equator to the polar region and carry cold water from poles back towards the equator .  This is  how ocean currents help to counteract the uneven distribution of solar radiation  , without ocean current it would be really hot in equator and really cold at poles.

Answer:

It demonstrates that the narrator is surrounded by nature.

Explanation:

Walt Whitman's "Crossing the Brooklyn Ferry" is a free verse poem written about the speaker's return trip on a ferry. He talks about his daily commute on the Brooklyn ferry, like the other commuters, and how they all share the same experience.

The given lines are from the very first stanza of the poem. The speaker repeats "face-to-face" when talking about nature. He sees the "flood-tide below" and the "clouds" high in the sky. This repetition demonstrates that he is surrounded by nature, amidst the throng of people around him. This shows the speaker's attitude of seeing the beauty of nature in any way he can, despite the bustle of commuting from Brooklyn to Manhattan.

Thus, the correct answer is the second option.

Answer:

1. 2.5 mm

2. 0.25 cm

Explanation:

Since the length of the 10 turns of the wire around the pencil is 25 mm, then;

1. the thickness of the wire = [tex]\frac{length of total turns}{number of turns}[/tex]

                                         = [tex]\frac{25}{10}[/tex]

                                        = 2.5 mm

The thickness of the wire is 2.5 mm.

2. Since 10 mm = 1 cm, then;

25 mm = 2.5 cm

So that,

the thickness of the wire in centimetre = [tex]\frac{length of total turns}{number of turns}[/tex]

                                         = [tex]\frac{2.5}{10}[/tex]

                                         = 0.25 cm

The thickness of the wire is 0.25 cm.

The sound level will be 109 decibels. If a person exceed hear a sound more than the certain sound level, the person hearing may damage.

Sound level is the intensity to measure the sound. Decibels are used to quantify sound level.

Sound level or the sound intensity is the ratio of  the power to the surface area;

[tex]\rm Intensity = \frac{Pow\pi er }{Surface \ area} \\\\ \rm Intensity = \frac{70}{ 4 \times \pi \times 8 \times 20^{2} } \\\\ I = \ 0.082 \ W/m^2[/tex]

The conversion of  the obtained value into the decibel as;

[tex]\rm I = 10 \times log \frac{I}{1 \TIMES 10^{-12}} \\\\\ I = 109 \ decibel[/tex]

Hence, the sound level will be 109 decibels.

Answer:

If it accelerated from 5 to 10 in one second then we know that acceleration is final (velocity-initial velocity)/

time

this gives (10-5)/1

=5m/s^2

force = mass x acceleration so = 150 x 5

this gives us a force of 750N

impulse is force x time so = 750 x 1

this tells us the impulse is 750 N.s

All of this is assuming it accelerated to 10m/s in one second.

The definition of impulse allows to find the impulse response for the acceleration of the body is:

Given parameters

To find

The impulse is the change of the momentum of a body, it is a vector quantity

    I = ∫ F. dt = Δp

Where the bold indicate vectors, I is the momentum, F the force, t the time, Δp the change in moment

The momentum is defined as the product of the mass of the body and its speed.

     p = m v

We substitute in the expression of impulse  

    I = [tex]m v_f - m v_o[/tex]  

Let's calculate.

    I = 150 (10 -5)

    I = 750 N s

In the direction of acceleration.

In conclusion using the definite of impulse we can find the impulse response for the acceleration of the body is:

Answer:

2 , 200%

Explanation:

Mechanical advantage of a machine is defined as how much the machine multiplies the applied force.

It is given that :

Input force of the lever = 40 N

The weight of the boulder or the output force = 80 N

Therefore, the mechanical advantage = output force / input force

                                                               [tex]$=\frac{80}{40}$[/tex]

                                                               = 2

Mechanical efficiency is obtained by the dividing the output by the input and multiplying it with 100.

i.e. Efficiency = output / input x 100

                      [tex]$=\frac{80}{40}\times 100$[/tex]

                     = 200 %
