Actual distance between earth and sun: 1 AU
Supposed distance: 4 AU
Given that the gravitational force is inverse to the square of the distance that separate the masses, this would be weaker if the distance is greater.
Here you hava a mathematical demonstration:
Gravitational force α 1/r^2 (α is used to indicate proportionality)
Actual Force / [1 /(1AU)^2] = New Force / [1 / (4AU)^2]
=> New Force = [1 / 16 AU^2 ] * Actual Force / [1 / 1 AU^2]
New Force = Actual Force / 16
Then, the new force would be weaker; exactly it would be one sixteenth of the actual force.
The first form of electric communication was called Morse Code. It uses long and short electric pulses (beeps) to encode letters. It is still used today.
Answer:
Force that the output plunger applies to the car; F2 = 3888N
Explanation:
For a hydraulic device, the relationship between the force and the area using Pascal's principle is;
F1/A1 = F2/A2
Where;
F1 is force applied to the input piston
F2 is force that the output plunger applies to the car
A1 is Area of input piston
A2 is area of larger piston
We are given;
R2/R1 = 9
So,R2 = 9R1
F1 = 48N
Area of input piston;
A1 = π(R1)²
Area of output piston;
A2 = π(9R1)²
Since, (F1/A1) = (F2/A2)
Thus;
F1/(π(R1)²) = F2/(π(9R1)²)
If we simplify, π(R1)² will cancel out to give;
F1 = F2/9²
Thus;
F2 = 9² x F1
Plugging in 48N for F1, we have;
F2 = 9² x 48
F2 = 81 x 48
F2 = 3888N
Answer:
very small amounts of mass
Explanation:
Nuclear fission is the splitting of large atomic nucleus into smaller nuclei.
Answer: because when you remove the battery, the the magnet no longer has electricity flowing through it, therefore the magnetic field disappears. Thats why its called a temporary magnet
