The gravitational effect on
other bodies determines the weight (or the mass) of a planet. We
must somehow measure the strength of its "tug" on another object in
order to use gravity to find the mass of a planet. We can harness Newton's
equations to deduce what the mass of the planet must be through observing
the time it takes for the satellite to orbit its primary planet.
Given:
Mass of Venus = 4.87 x 1024 kg
= 4986.88
Mass of Jupiter = 1.898 x 1024 kg
= 1943.552
Mass of Jupiter compared to mass of
Venus
1943.552 / 4986.88
= 0.3897330595482546
= 0.3897330595482546 x 100%
= 38.97%
So, in this problem, <span>the mass of Jupiter is about 0.39 times the mass of Venus.</span>
Explanation:
Let us assume that the separation of plate be equal to d and the area of plates is 
. As the capacitance of capacitor is given as follows.
C = 
It is known that the dielectric strength of air is as follows.
E = 
Expression for maximum potential difference is that the capacitor can with stand is as follows.
dV = E × d
And, maximum charge that can be placed on the capacitor is as follows.
Q = CV
= 
= 
= 
= 
or, = 10.62 nC
Thus, we can conclude that charge on capacitor is 10.62 nC.
Only ' A ' is always true.<em> (choice-1)</em>
' B ' is not true when you drop a red hot spoon into cold soup.
' C ' is not true when you drop a red hot marble into a cool swimming pool.
Since the car is driven 125km west and then 65km north, we simply add the two values together to get 190km
