The image that shows an object or objects moving with <u>non-accelerated motion</u> is <u>the first image</u>.
Why?
When we are thinking about a non-accelerated motion, we know that the speed will be constant all the time, it means that no matter the time, if we took two consecutive moments of time knowing the object's position, and we are able to calculate the distance between those instants of time, <u>the distance will be the same.</u>
On the other hand, if we have an accelerated motion, it means that the speed will not be constant, so the distance between two consecutive instants of time might not be the same.
From the given image, we can see that the only image that describes a non-accelerated (constant speed) is the first image.
Have a nice day!

You haven't given us enough information to figure out an answer.
It depends on whether the light bulb is part of a series or parallel circuit,
and whether there are also OTHER light bulbs in the same circuit.
-- If the light bulb is the ONLY one in the circuit, or if it's one of
several bulbs that are connected in parallel across the same battery,
and you replace it with a bulb that has higher resistance, then the
new one will be LESS BRIGHT than the original one.
-- If the light bulb is one of two or more bulbs connected in series
across the battery, and you replace it with a bulb that has higher
resistance, then the new one will be BRIGHTER than the original
one was.
Explanation:
Given that,
Radius = 10.5 cm
Magnetic field = 0.117 T
Time = 0.243 s
After stretched, area is zero
(I). We need to calculate the magnetic flux through the loop before stretched
Using formula of magnetic flux
Where, B = magnetic field
r = radius
Put the value into the formula
(II). We need to calculate the magnetic flux through the loop after stretched
Here, A = 0
So, The magnetic flux through the loop after stretched is zero.
(III). We need to calculate the magnitude of the average induced electromotive force
Using formula of the induced electromotive force
Hence, This is the required solution.
Weight Force of Junior = m g = 115kg x 9.81 m/s^2 = 1128.15N then
compute for the friction force
Friction Force= WF x (coefficient of kinetic friction) = 1128.15N x 0.35 = 394.8525N or 395N
But you can compute in a straightway:
Solution:
= 115 x 9.81 x 0.35
= 394.85
= 395 N
It will still give the same results.
