The terminal speed of the marble is 0.588 m/s.
Given:
We know that,
F = mg ......(1)
where,
F = force
m = mass
g = acceleration due to gravity
Also,
v = F/k ......(2)
where,
v = terminal speed
k = proportionality constant
Substituting the value of F from equation (1) in equation (2)
v = mg/k .......(3)
Given,
m = 30 g = 0.030 kg
k = 0.500 kg/s
g = 9.8 m/s²
To find,
v =?
Put the values in equation (3)
v = mg/k
v = 0.03(9.8)/ 0.500
= 0.294/0.500
= 0.588 m/s

<h3><u>Answer;</u></h3>
The above statement is False
<h3><u>Explanation;</u></h3>
- Decreased output from the vasomotor center allows arterioles and veins to dilate.
- The vasomotor center controls vessel tone or contraction of the smooth muscle in the tunica media.It is responsible for central regulation of cardiac electrical activity, myocardial performance, and peripheral vascular tone.
- Changes in diameter affect peripheral resistance, pressure, and flow, which in turn affect cardiac output.
D: An electromagnet with 20 coils.
That is because the more coils of the wire, the stronger the electromagnet is.
The μs between the clock and floor is 650(M*g) and the μk between the clock and the floor is 560(M*g)
