The weight of an object is given by
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:
and this is the strength of the gravity on Jupiter's surface.
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.
<em>Note: Your question inputs seem a little odd. But, I am assuming that you really mean '10km in 5 ms'.</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
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;
The diameter of the hose is calculated as follows;
Thus, the diameter of the hose is 6.34 cm.
