Suppose a woman raises a 65 N object in 2m in 4 seconds.
Calculate the work is done and her power.
Science
Answer:
[tex]\huge\boxed{\sf P.E = 130\ Joules}[/tex]
[tex]\huge\boxed{\sf P = 32.5\ Watts}[/tex]
Explanation:
Given Data:
Weight = W = 65 N
Height = h = 2 m
Time = t = 4 secs
Required:
Power = P = ?
Work Done in the form of Potential Energy = P.E. = ?
Formula:
P.E. = Wh
P = P.E. / t
Solution:
P.E. = (65)(2)
P.E = 130 Joules
P = P.E. / t
P = 130 / 4
P = 32.5 Watts

What property of light waves makes it possible to use waves to transmit information between a space shuttle and NASA mission control centers on the ground?
Answer:
Explanation: Because it was able to exhibit an electromagnetic property hence, it is transverse meaning that
each wave is perpendicular to the direction of propagation.
And recall that an Electromagnetic waves can travel through a vacuum.
Ms. Lachance has to pick up her daughter from the airport and is running late. As she pulls her car out of the driveway and starts to drive down the road, she takes off as fast as her car will go. When she does this her coffee cup, which she left on the hood by accident flies into the windshield making it hard for her to see. Using Newton’s first law, explain why the coffee spilt all over the windshield.
Answer:
the gravity was pulling the cup to the front of the window even though the wind was pushing it the other way.
Explanation: the gravity must be strong
By using the Newton's first law of Motion, it can be explained why the coffee spilt all over the windshield. This is because there is gravitational force which acts upon it and it pushes the substances in the downward direction towards the Earth.
What is Newton's first law of motion?
Newton's first law of Motion states that a body remains in the same state of rest or uniform motion in a straight line unless and until an external force is applied on it. This means that a body will not start moving by itself until and unless an external force acts on it.
In this case, lachance's daughter is trying to pick her coffee cup, the coffee cup at the windshield is spilt which makes it difficult for her to see. This is because, there is the gravitational force or gravity which is pulling the coffee cup to the front of the window even though the wind was pushing it in the other way.

How do latitude and proximity to bodies of water relate to the temperature?
Answer:
The answer is below.
Explanation:
According to geographical coordinates and related information, when the latitude is lower, that is closer to the equator the temperature becomes warmer. While the far away from the equator the latitude is the temperature decreases.
Similarly, the water bodies have a relative effect that is considered little or less severe on the temperature throughout any of the seasonal period or day and night.
The greenhouse effect is when the sun's heat is trapped in the atmosphere warming the earth. True or false
Answer:
True
Explanation:
I believe the answer is true.
According to the rock cycle, when liquid magma cools into a solid, what is formed?
Answer:
Similarly, liquid magma also turns into a solid — a rock — when it is cooled. Any rock that forms from the cooling of magma is an igneous rock. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind. ... The kind of rock formed in this way is called intrusive igneous rock.
Explanation:
Answer: Igneous rock.

Answer:
The x-component of [tex]F_{3}[/tex] is 56.148 newtons.
Explanation:
From 1st and 2nd Newton's Law we know that a system is at rest when net acceleration is zero. Then, the vectorial sum of the three forces must be equal to zero. That is:
[tex]\vec F_{1} + \vec F_{2} + \vec F_{3} = \vec O[/tex] (1)
Where:
[tex]\vec F_{1}[/tex], [tex]\vec F_{2}[/tex], [tex]\vec F_{3}[/tex] - External forces exerted on the ring, measured in newtons.
[tex]\vec O[/tex] - Vector zero, measured in newtons.
If we know that [tex]\vec F_{1} = (70.711,70.711)\,[N][/tex], [tex]\vec F_{2} = (-126.859, 46.173)\,[N][/tex], [tex]F_{3} = (F_{3,x},F_{3,y})[/tex] and [tex]\vec O = (0,0)\,[N][/tex], then we construct the following system of linear equations:
[tex]\Sigma F_{x} = 70.711\,N - 126.859\,N +F_{3,x} = 0\,N[/tex] (2)
[tex]\Sigma F_{y} = 70.711\,N + 46.173\,N+F_{3,y} = 0\,N[/tex] (3)
The solution of this system is:
[tex]F_{3,x} = 56.148\,N[/tex], [tex]F_{3,y} = -116.884\,N[/tex]
The x-component of [tex]F_{3}[/tex] is 56.148 newtons.
1. How does speed affect the amount of kinetic energy in a moving object? Explain how you
know by stating your claim, the evidence for your claim, and your reason why this evidence
supports your claim.
I’ll mark as brainliest
Explanation:
The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with equal mass and twice the speed will have quadruple the kinetic energy.
Mass of 2 x 1021 number of atoms of a
element is 0.49. What is the mass of 0.5 mole of a b
element?
Answer: The mass of 0.5 mole of element ab is 81.67 g.
Explanation:
According to the mole concept, 1 mole of a substance contains [tex]6.022 \times 10^{22}[/tex]. As, the mass of [tex]2 \times 10^{21}[/tex] atoms is 0.49 g.
So, [tex]\frac{2 \times 10^{21}}{6.022 \times 10^{23}} mol = 0.49 g[/tex]
[tex]0.003 mol = 0.49 g[/tex]
Therefore, mass of 1 mole = [tex]\frac{0.49}{0.003}[/tex]
= 163.33 g/mol
Hence, mass of 0.5 mole of ab element is calculated as follows.
[tex]0.5 mol \times 163.33 g/mol[/tex]
= 81.67 g
Therefore, the mass of 0.5 mole of element ab is 81.67 g.
Why can we say that the ratio of net force to mass is constant forany dropped object on Earth?
Answer:
All objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.

A badminton shuttlecock leaves the racquet traveling 30 m/s. It goes over the net 0.5
seconds later with a speed of 10 m/s. Calculate its average acceleration.
Answer:
[tex]a=40\ m/s^2[/tex]
Explanation:
Given that,
Initial speed of a shuttlecock, u = 30 m/s
Final speed of the shuttlecock, v = 10 m/s
Time, t = 0.5 s
We need to find its average acceleration. The acceleration of an object is equal to the change in speed divided by time taken. It is given by :
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{10-30}{0.5}\\\\a=-40\ m/s^2[/tex]
So, the average acceleration of badminton shuttlecock is [tex]40\ m/s^2[/tex].

Answer:
22. 2 sec
23. 3 sec
24. 50 sec
Explanation:
J = (P)*(t)
t = J/P
22.
t = (80 J)/(40 W)
t = 2 s
23.
t = (2,700,000 J)/(900,000 W)
t = 3 s
24.
t = (10,000 J)/(200 W)
t = 50 s

A) Pitch depends on the frequency of a sound wave. The higher the pitch, the higher the frequency and the lower the pitch, the lower the frequency. Sound waves have different pitches due to varying frequency levels.
B) Sound is created as the pen vibrates. This vibrations also interacts with the air atoms and molecules, causing them to vibrate too, therefore, creating sound waves. The reason the brain grows annoyed at this continual sound is because the brain will focus on this sound only, causing the brain to go into overdrive, creating annoyance.
C) Sound waves are travelling vibrations of particles. Space does not have any atoms or particles for the sound vibrations to interact with, therefore creating zero sound waves to travel.
