Answer:
Explanation:
The relation between time period of moon in the orbit around a planet can be given by the following relation .
T² = 4 π² R³ / GM
G is gravitational constant , M is mass of the planet , R is radius of the orbit and T is time period of the moon .
Substituting the values in the equation
(.3189 x 24 x 60 x 60 s)² = 4 x 3.14² x ( 9380 x 10³)³ / (6.67 x 10⁻¹¹ x M)
759.167 x 10⁶ = 8.25 x 10²⁰ x 39.43 / (6.67 x 10⁻¹¹ x M )
M = .06424 x 10²⁵
= 6.4 x 10²³ kg .
The ammeter reading (current) will decrease.
V=IR
I = V/R
so I is inversely proportional to R, i.e. increasing R will cause I to decrease
Answer:
The force exerted by the cart on Bonnie is - 18.0 N
Explanation:
Given;
weight of the cart, w = 195 N
Bonnie's applied force on the cart, F = 18.0 N
According to Newton's 3rd law, action and reaction are equal and opposite.
Thus, the cart will pull back at Bonnie with force of equal magnitude but in opposite direction.
The force exerted by the cart on Bonnie = - 18.0 N
