Answer:
50 arcsec.
Explanation:
Diameter of the Jupiter is 139822 km.
Minimum distance of the Jupiter from the earth is,
Now angular diameter of the Jupiter from the Earth can be calculate as,
Here, D is the diameter, and S is the minimum distance from the observing planet.
Now,
We know that,
Therefore,
Therefore, the angular diameter of planet Jupiter is 49.07 arcsec which is quite close to the 50 arcsec which is given in options.
A motor is used to lift a person sitting on a platform that, combined weighs 650 N. The platform is lifted 25.0 m straight up in 18.0 seconds. What power is developed by the motor in watts?
<span>G:ivens: Force, F, displacement, s and time, t </span>
<span>U:nkowns: Power, P </span>
<span>E:quation: P = Fs/t </span>
<span>S:ubstitute P = (650 x 25)/18 </span>
<span>S:olve P = 902 7/9 watts</span>
