Answer:
100 times
Explanation:
Question:
The cylinders of a hydraulic part are 15cm and 150cm in diameter. How many times will the force acting on the piston with the smaller diameter be multiplied?
Solution:
Smaller diameter = 15cm
Bigger diameter = 150cm
Using Pascal's principle
F/A = f/a
Pressure = Force/Area
Pressure on piston with bigger diameter = pressure on piston with smaller diameter
Let Pressure on piston with bigger diameter = P
P =F/A
pressure on piston with smaller diameter = p
p = f/a
F/A = f/a
F×a = f×A
F/f = A/a
Area = πr^2
F/f = [π×(150)^2]/ [π×(15)^2]
F/f = (150)^2/ (15)^2
F/f = 100
F = 100f
The force acting on the piston with the smaller diameter will be multiplied 100 times.
Answer:
724,000,000,000 = ![7 * 10^{11}](https://tex.z-dn.net/?f=7%20%2A%2010%5E%7B11%7D)
Explanation:
To convert a number into scientific notation, we have to find how many digits are after the first digit so:
7, 2 4 0 0 0 0 0 0 0 0 0
11 digits are after 7
Meaning to make it into scientific notation, the power of 10 would be 11
![10^{11}](https://tex.z-dn.net/?f=10%5E%7B11%7D)
Answer:
The gram is the basic unit of measurement
Explanation:
You use it to weigh small items such as sugar, flour, coffee, and other items that are similar.
If you want to measure in grams using a scale is the most accurate solution.

Answer:
Explanation:
Gravitational law states that, the force of attraction or repulsion between two masses is directly proportional to the product of the two masses and inversely proportional to the square of their distance apart.
So,
Let the masses be M1 and M2,
F ∝ M1 × M2
Let the distance apart be R
F ∝ 1 / R²
Combining the two equation
F ∝ M1•M2 / R²
G is the constant of proportional and it is called gravitational constant
F = G•M1•M2 / R²
So, to increase the gravitational force, the masses to the object must be increased and the distance apart must be reduced.
So, option c is correct
C. Both objects have large masses and are close together.
