Answer:
967500000 years
Explanation:
The Speed at which the radius of the orbit of the Moon is increasing is 4 cm/yr
Converting to m
1 m = 100 cm
The distance by which the radius increases is 3.84×10⁷ m
Time = Distance / Speed
967500000 years will pass before the radius of the orbit increases by 10%.
ANSWER
8.99 F
EXPLANATION
We know that two capacitors of capacitances 2.8 F and 5.57 F are connected in series, while a third capacitor of capacitance 7.13 F is connected in parallel to that combination,
The capacitance works similarly to the resistance, except that when capacitors are connected in parallel, their capacitances add up, while when they are connected in series, the equivalent capacitance is like we were finding the equivalent resistance of resistors connected in parallel,
Hence, the total capacitance is 8.99 F, rounded to the nearest hundredth.
Answer:
d. remains same
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
If both the mass of the body and the force acting on it are doubled, then acceleration remains the same.
Given the following data;
Mass = 2Mass
Force = 2Force
Substituting into the formula, we have;
