I am 11 year old and I don't known the answer to this question
Answer:
Option B. The distance between the objects in Figure A is shorter than the distance between the objects in Figure B.
Explanation:
The force of attraction between two masses is given by the following equation:
F = GM₁M₂ / r²
Where:
F => is the force of attraction
M₁ and M₂ => are the masses of the two objects
G => is the gravitational constant.
r => is the distance between the two objects
From the above formula,
The force of attraction (F) is directly proportional to the product of the two masses and inversely proportional to the square of their apart.
This implies that:
1. An increase in the masses of the object will bring about an increase in the force of attraction and a decrease in the masses will leads to a decrease in the force of attraction.
2. An increase in the distance between the two masses will leads to a decrease in the force of attraction and a decrease in the distance between the two masses will lead to an increase in the force of attraction.
Considering the options given in the question above, option B gives the correct answer to the question.
If the frequency is large then the period is short and if the frequency is small then the period is long
Answer:
Explained
Explanation:
Lunar mountains are smoothly rounded rather than having sharp, pointed peaks because the lunar moons are formed because of the impact of asteroids and comets on its surface whereas the Earth mountains are formed because of the surface activity of volcanos, collision of land masses and activity of plate tectonics that is why they have sharp and pointed tops.
Answer:
<em>The input power is 200 W</em>
Explanation:
<u>Motor Efficiency</u>
The efficiency of a motor can be calculated as follows:
Where:
β = efficiency
Po = Output power
Pi = Input power
Solving for Pi:
The efficiency is β=0.75 and the output power is Po=150 W, thus the input power is:
The input power is 200 W
