Answer:
Ratio of length will be
Explanation:
We have given time period of the pendulum when length is is
And when length is time period
We know that time period is given by
So ----eqn 1
And -------eqn 2
Dividing eqn 2 by eqn 1
Squaring both side
Answer:
c. 972
Explanation:
The volume of a rectangular solid is calculated as the product of its dimensions, that is, its width, its length and its height:
1 feet is equal to 12 inches, so:
Now, we calculate the volume of the object in cubic inches:
Answer:
Let's see the similarities between the two forces
* are proportional to the product of a magnitude, mass or charge
* They are inversely proportional to the square of the distance
* They are long-range forces since zero is not made up to an infinite distance. The gravitational force is always attractive, the electrical force can be attractive or repulsive.
The differences in them
* The electric force in much greater than the gravitational force
* The gravitational force is always attractive, the electrical force can be attractive or repulsive.
Explanation:
Let's start by calculating each force.
Gravitational force
F =
let's calculate
F = 6.67 10⁻¹¹ 1 1 / 1²
F = 6.67 10⁻¹¹ N
Electric force
F =
indicates that the charge is q = 10 C
F = 9 10⁹ 10 10 / 1²
F = 9 10¹¹ N

Answer:
See the explanation below
Explanation:
To better understand this problem, a cylinder sketch is attached before and after the cut, we see that after the cut, the shape of this resembles that of a right triangle.
We can find, the centroid in the xy plane, knowing that the centroid for a triangle is located a third of its base.
In the z axis there is no displacement of the centroid.
