Answer:
<em>110.7Joules</em>
Explanation:
<em>Work is said to be done when the force applied to a body cause the body to move through a distance.</em> Mathematically:
Work done = Force * Distance
Given the following
Force = 270 -0 = 270N
Distance moved = 0.410m
Required
The work done
Substitute the given parameters into the formula
Workdone = 270 * 0.41
Workdone = 110.7Joules
<em>Hence the work done in pulling the bow is 110.7Joules</em>
Answer:
Explanation:
Mass of the cable car, m = 5800 kg
It goes 260 m up a hill, along a slope of 
Therefore vertical elevation of the car = 
Now, when you get into the cable car, it's velocity is zero, that is, initial kinetic energy is zero (since K.E. = 
). Similarly as the car reaches the top, it halts and hence final kinetic energy is zero.
Therefore the only possible change in the cable car system is the change in it's gravitational potential energy.
Hence, total change in energy = mgh = 
where, g = acceleration due to gravity
h = height/vertical elevation
Answer:
B= 4,000 km

I just took the test on edge :)
Answer:
The solar wind is created by the outward expansion of plasma (a collection of charged particles) from the Sun's corona (outermost atmosphere). This plasma is continually heated to the point that the Sun's gravity can't hold it down. It then travels along the Sun's magnetic field lines that extend radially outward.
<u>No</u>, Photons are absorbed in a quantum jump from a lower energy level to a higher energy level.
When an electron moves closer to the nucleus and emits a photon, to move an electron further from the nucleus requires the absorption of a photon.
A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules.
