Answer:
(a) Fₓ = 0 N
= 9.08 N
(b)
(a) Fₓ = 0 N
<u></u> = 9.08 N
(c) = 0 N
Fₓ = 9.08 N
Explanation:
The magnitude of the force will remain the same in each case, which is given as follows:
F = ma (Newton's Second Law)
where,
F = force = ?
m = mass = 4.54 kg
a = acceleration = 2 m/s²
Therefore,
F = (4.54 kg)(2 m/s²)
F = 9.08 N
Now, we come to each scenario:
(a)
Since the motion is in the vertical direction. Therefore the magnitude of the force in x-direction will be zero:
<u>Fₓ = 0 N</u>
For upward direction the force will be positive:
<u></u><u> = 9.08 N</u>
<u></u>
(b)
Since the motion is in the vertical direction. Therefore the magnitude of the force in x-direction will be zero:
<u>Fₓ = 0 N</u>
For upward direction the force will be negative:
<u></u><u> = - 9.08 N</u>
<u></u>
(c)
Since the motion is in the horizontal direction. Therefore the magnitude of the force in y-direction will be zero:
<u></u><u> = 0 N</u>
<u>Fₓ = 9.08 N</u>
No, because the distance-time would show a constant velocity but the velocity-time graph shows an increasing velocity.
difference across the 12.0 Ω resistor is 1.20 V, calculate the emf of the cell. 45. Req = 13.5 Ω ... (b) I = V / Reff = 1.5 / 2 = 0.75 A.
Answer:
0.4 Kilograms of flour
Explanation:
If you convert 400 grams into kilograms (400 ÷ 1,000), you would get 0.4 kilograms.
D) decreases, inverse
Explanation:
The average speed of each lap decreases. This is an example of an inverse relationship.
Speed is the rate of change of distance with time. In calculating the average speed, we should understand that the total length of path is taken into consideration and so is the total time taken.
Average speed = 
It was explained that after every 5 seconds the speed of the runner becomes slower.
There is definitely an inverse relationship between average speed and the total time taken.
An inverse relationship is such that as one variable increases, the other diminishes.
As average speed reduces the time taken increases.
