Answer:
54.67 N
Explanation:
The total energy produced is the product of power and time duration:
E = Pt = 82 * 1 = 82 J
Which is converted from work, product of forced extended over a displacement
W = E = Fs = F*1.5 = 82
F = 82 / 1.5 = 54.67 N
So the magnitude of the force exerting on the handle is 54.67 N
Answer:
151.2 m/s
Explanation:
m1 = 0.020 kg
m2 = 2.5 kg
vf = 1.2 m/s
m1v1 +m2v2 = (m1 +m2)vf
0.020v1 + 0 = (0.020 +2.5)(1.2)
---> 151.2 m/s
Answer:
Input power, Ip = 4 Watts
Explanation:
Given the following data;
Power output = 0.8 Watts
Efficiency = 20%
To find the power input of the sunlight onto the solar panel;
Mathematically, the efficiency of a machine is given by the formula;
Substituting into the formula, we have;
Cross-multiplying, we have;
Input power, Ip = 4 Watts
Answer:
Independent variables ; Water and Gatorade
Dependent variable ; You ( sport person )
Explanation:
The independent variables are ; Water and Gatorade
This is because these are the variables the team will always alternate in other to determine which has more hydrating effect on the user in the long run
while
The dependent variable here is You
This is because your level of hydration depends on the Drinking water or Gatorade been fed to you in the next 6 games.
1) 487 miles / 65 miles per hour = 7.5h at max speed
2) 9.8h - 7.5h = 2.3h rest time avaliable
