Answer:
m = 48.93kg
The load is 48.93kg.
Explanation:
Given;
Power P = 100watts
Efficiency e = 60% = 0.60
distance d = 10 m
time taken t = 80 s
Acceleration due to gravity g = 9.81m/s
Workdone W can be expressed as;
W = ePt = Fd = mgd
ePt = mgd
Making m the subject of formula;
m = ePt/gd
Substituting the values;
m = (0.60×100×80)/(9.81×10)
m = 48.93kg
The load is 48.93kg.
Answer:
2 x 10^20 N
Explanation:
Me = 5.98 x 10^24 kg
Mm = 7.36 x 10^22 kg
r = 3.82 x 10^5 km = 3.82 x 10^8 m
The gravitational force between earth and moon is
F = G Me x Mm / r^2
F = (6.67 x 10^-11 x 5.98 x 10^24 x 7.36 x 10^22) / (3.82 x 10^8 x 3.82 x 10^8)
F = 2 x 10^20 N
Answer: direction
Explanation:
Given
The resultant vector of a force gives us information regarding the direction of the resultant force.
If there are multiple forces acted in a different direction then, the resultant vector describes the direction of the resultant force.
Answer:
Amplitude make wave property affect the loudness of sound
The radial force on the particle is given by the Lorentz force. They don't give you the velocity so you have to solve for it in terms of the radius and get them to cancel.
