The gravitational force will be one quarter.
The gravitational force between two objects is given by the formula
F=GMm/r^2
here, r is the distance between the objects.
Thus the gravitational force is inversely proportional to the square of the distance between the objects, Therefore if the distance between two objects is doubled the force will be one quarter.
To solve this problem we will apply the linear motion kinematic equations, specifically the concept of acceleration as a function of speed and time, as well as Newton's second law.
PART A) Acceleration can be described as changing the speed in a period of time therefore,
Force is the proportional change between mass and acceleration therefore
PART B) We will apply the same concept given but now we will change the time to 21s therefore:
Now the force
When the resistance R is doubled, I = 1 A
One of the most fundamental and significant principles controlling electrical and electronic circuits is called Ohm's Law. For a linear device, it relates current, voltage, and resistance.
According to Ohm's Law, the current flowing through a circuit is inversely proportional to the resistance in the circuit and directly proportional to the applied potential difference.
Ohm's law can be written mathematically as follows:
V = IR
Where:
V = voltage expressed in Volts
I = current expressed in Amps
R = resistance expressed in Ohms
If any two quantities are known, the third can be computed by manipulating the formula.
I= V/R
R= V/I

Total resistance will be R1 + R2.
And the formula will be I equals V over R.
V=5
I=?
R=6
I= 0,83 amps
Answer:
Explanation:
We need the power equation for this which is
P = Work/time
We have everything we need to solve this (the mass of the object is extra information):
P = 6860/4
P = 1715W
