We are given a bucket with pennies. We are asked to increase the gravitational potential energy. The gravitational potential energy is the energy that is related to the position of the object and is determined by the following formula:
This means that the gravitational potential energy depends on the height and the mass. Therefore, to increase the gravitational potential energy we must increase the height of the bucket. Therefore, we need to add more books. Therefore, the right option is B.
Answer:
Explanation:
Behind the second car , no of cars = 13
total mass of 13 cars = 13 x 37000 Kg
acceleration = .46 m /s²
If T be the tension
This tension is pulling 13 cars
force = mass x acceleration.
T = 13 x 37000 x .46
= 221260 N .
For this you will need to use the Pythagorean’s theorem
Drawing this out may help!!
If you draw it out, you will get a triangle with a hypotenuse that’s you need to find out.
So 50^2 + 75^2
Square root = 8.67 approx
So displacement is 8.67 metres
Answer:
Since there is only one path for the charges to flow through, the current is the same through each resistor. The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances.
