Mosa believes that ocean currents help to regulate the climate of the earth. Explain why.
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 .
What is an ocean currents ?
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.

10 turns of wire are closely wound around a pencil as shown in the figure. when measured using a scale as shown, the length of total turns is obtained 25mm. then a) What is the thickness of the wire? b) Express the thickness of the wire in centimetre.
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.

A lift moves i)up
and ii) down with an
acceleration of 2 ms
{s}^{ - 2} . In cach case, calculate
the reaction of the floor on a man
of mass 50kg standing in the lift.
Answer:
i) The reaction of the floor on the 50 kg man in the lift to lift up the man is 590 Newtons
ii) The reaction of the floor on the 50 kg man in the lift to move down the man is 390 Newtons
Explanation:
i) The acceleration of the lift upwards, a = 2 ms⁻²
The mass of the man standing in the lift, m = 50 kg
According to Newton's third law of motion, action and reaction are equal and opposite
Therefore, the force with which the elevator lifts the man = The reaction of the floor on the 50 kg man in the lift to lift up the man = The action of the man on the floor
∴ The force with which the elevator lifts the man up, F = The weight of the man, m·g + The force of the upward motion of the man, m·a
F = m·g + m·a
Where;
g = The acceleration due to gravity = 9.8 m/s²
m = The mass of the man = 50 kg
a = The acceleration of the lift = 2 m/s²
∴ F = 50 kg × 9.8 m/s² + 50 kg × 2 m/s² = 590 Newtons
The reaction of the floor on the 50 kg man in the lift to lift up the man = The force with which the elevator lifts the man up, F = 590 Newtons
ii) The reaction of the floor on the man when the acceleration of the lift is downwards, a = 2 ms⁻², is given as follows;
The force with which the elevator takes the man downwards, F = The reaction of the floor on the 50 kg man in the lift to lift up the man
The force with which the elevator takes the man downwards, F = The weight of the man, m·g - The force of the downward motion of the man, m·a
F = m·g - m·a
∴ F = 50 kg × 9.8 m/s² - 50 kg × 2 m/s² = 390 Newtons
The reaction of the floor on the 50 kg man in the lift to move down the man = The force with which the elevator takes the man downwards, F = 390 Newtons

An object of mass 150 kg accelerates from a velocity of 5m/s to a velocity of 10m/s in the same direction. What is the impulse provided to cause this acceleration?
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:
The impluse in acceleration direction is: I = 750 N s
Given parameters
Body mass m 150 kg The initial velocity vo = 5 m / s The final velocity vf = 10 m / sTo find
Impulse
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:
The impluse in acceleration direction is: I = 750 N s

Susie rolls a bowling ball down the alley and knocks over most of the pins. Explain why fewer pins were knocked over when her little brother rolled a basketball, at the same velocity, down the alley.
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
Read the excerpt from " Crossing the Brooklyn Ferry." Flood-tide below me! I see you face to face! Clouds of the west – sun there half an hour high – I see you also face to face. Which statement best describes the effect of repeating the phrase "face to face"? It shows that the narrator sees the facial features of others. It demonstrates that the narrator is surrounded by nature. It demonstrates that the narrator is surrounded by people. It shows that the narrator is suspicious of the sea and sky.
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.

What are the mechanical advantage and mechanical efficiency of a lever that requires an input force of 40 N and lifts and lifts a boulder that weighs 80 N?
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 %

If you are sitting 8.20 m from a
70.0 W speaker, what is the
sound level in dB?
(Treat the speaker as a point source.)
(Unit = dB)
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.
What is sound level?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.
