To calculate speed, you need to know the total distance covered
and the time it took to cover the distance.

To calculate velocity, you need the starting location, the ending location,
and the time it took to go from start to finish.

If a 0.5 kg pair of running shoes would weigh 11.55 Newton’s on Jupiter, what is the strength of gravity there?
OverLord2011 [107]
The weight of an object is given by
F=mg
where m is the mass of the object, while g is the strength of the gravity (which corresponds to the gravitational acceleration of the planet).

In our problem, the shoes have a mass of m=0.5 kg, and their weight is F=11.55 N. So, we can re-arrange the previous formula to find the value of g:
g= \frac{F}{m}= \frac{11.55 N}{0.5 kg}=23.1 N kg^{-1}
and this is the strength of the gravity on Jupiter's surface.

The distance between the lenses in a compound microscope is 18 cm. The focal length of the objective is 1.5 cm. If the microscop
Blababa [14]

Answer:

The focal length of eye piece is 6.52 cm.

Explanation:

Given that,

Angular Magnification of the microscope M = -46

the distance between the lens in microscope L= 16 cm

The focal length of objective f₀ = 1.5 cm

Normal near point N = 25 cm

Have to find focal length of eye piece f ₙ =?

The angular magnification is given by

M ≈ - (L-fₙ)N/f₀fₙ

Rearranging for fₙ

fₙ =L(1 - Mf₀/N)⁺¹

   =18/2.76

fₙ =  6.52 cm

The focal length of eye piece is 6.52 cm.

I mon runs a distance of 10km in 5 ms<br>he overage speed​
Harrizon [31]

<em>Note: Your question inputs seem a little odd. But, I am assuming that you really mean '10km in 5 ms'.</em>

<em></em>

Answer:

The Average speed = 15000 / 0.005 = 3000000 m/s

Explanation:

  • Average speed can be calculated by dividing the total distance covered by the total time.

Average speed = Total Distance / Total time

Given

  • Total distance = 15km = 15(1000) = 15000 m
  • Total time = 5 ms = 0.005 seconds

Thus,  

Average speed = Total Distance / Total time

Average speed = 15000 / 0.005 = 3000000 m/s

If the pipe of the previous exercise is connected to a hose and the speed there is 3.8 m/s, what is the diameter of the hose?
Amiraneli [1.4K]

The diameter of the hose is 6.34 cm.

<em>"Your question is not complete, it seems to be missing the following information";</em>

the flow rate of water in the pipe is 0.012 m³/s

The given parameters;

  • velocity of water in the hose, v = 3.8 m/s
  • flow rate of water in the hose, Q = 0.012 m³/s

Volumetric flow rate is directly proportional to the product of the area of the hose through which the water flows and the velocity of the water flowing through the hose.

 Q = Av

where;

<em>Q is the volumetric flow rate</em>

<em>A is the area of the hose</em>

<em>v is the velocity of flow</em>

The area of the hose is calculated as follow;

A = \frac{Q}{v} \\\\A = \frac{0.012}{3.8} \\\\A = 0.00316 \ m^2

The diameter of the hose is calculated as follows;

A = \frac{\pi D^2}{4} \\\\\pi D^2 = 4A\\\\D^2 = \frac{4 \times A}{\pi} \\\\D =  \sqrt{\frac{4 \times A}{\pi} } \\\\D = \sqrt{\frac{4 \times 0.00316}{\pi} } \\\\D = 0.0634 \ m\\\\D = 6.34 \ cm

Thus, the diameter of the hose is 6.34 cm.
