The terminal speed of the marble is 0.588 m/s.

<h3>Calculation:</h3>

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

​

Hence, the terminal speed of the marble is 0.588 m/s.

0.588 m/s

0.588 m/s is the terminal speed of the marble.

<h3>Calculation:</h3>

We know that,

F = mg  ----> eq(1)

where,

F = force

m = mass

g = acceleration due to gravity

We also know,

v = F/k ----> eq(2)

where,

v = terminal speed

k = proportionality constant

On substituting the value of F from eq(1) in eq(2)

v = mg/k  

Given,

m = 30 g = 0.030 kg

k = 0.500 kg/s

g = 9.8 m/s²

we need to find,

v =?

substitute the values in equation (3)

v = mg/k            

v = 0.03(9.8)/ 0.500

 = 0.294/0.500

 = 0.588 m/s

Hence, the terminal speed of the marble is 0.588 m/s.

A 40kg load is raised to a height of 25m. If the operation requires 1 min, find the power required​
OlgaM077 [116]

Answer:

163.33 Watts

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 40 Kg

Height (h) = 25 m

Time (t) = 1 min

Power (P) =..?

Next, we shall determine the energy. This can be obtained as follow:

Mass (m) = 40 Kg

Height (h) = 25 m

Acceleration due to gravity (g) = 9.8 m/s²

Energy (E) =?

E = mgh

E = 40 × 9.8 × 255

E = 9800 J

Finally, we shall determine the power. This can be obtained as illustrated below:

Time (t) = 1 min = 60 s

Energy (E) = 9800 J

Power (P) =?

P = E/t

P = 9800 / 60

P = 163.33 Watts

Thus, the power required is 163.33 Watts

PLS HELP<br><br> compare longitudinal and transverse waves
babymother [125]
<span>A transverse wave is one for which the direction of oscillation is perpendicular to the direction of propagation of the wave whereas, for longitudinalwaves oscillations are in the direction of propagation. Ripples in pond water move about the surface of water and they simultaneously move away from the point-0 too.</span><span>
Longitudinal waves include sound waves(vibrations in pressure, particle of displacement, and particle velocity propagated in an elastic medium) and seismic P-waves (created by earthquakes and explosions). In longitudinal waves, the displacement of the medium is parallel to the propagation of thewave.
