Another engineer is running a series of experiments with hydraulic systems. If she doubles the area of the input piston, what happens to the amount of pressure transmitted by the system?
Answer:
The pressure remains the same.
F = P * A the amount of force transmitted would double if only the input area is changed. Pressure is the same at all points in the system.
Explain swimming based on one of the laws of motion?
Answer:
Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. Thus, swimmers must stroke downward in the water to stay afloat and propel forward. This movement is equal and opposite to the force the water exerts against the swimmer to stop them from moving.
_______is the force that keeps us all stuck to the surface of our planet.

Calculate the tension on the rope.
A. 57.89 N
B. 32.73 N
C. 69.84 N
D. 12.55 N
Hi there!
[tex]\large\boxed{\text{B. 32.73N}}[/tex]
To calculate the tension, we must calculate the acceleration of the system.
Begin with a summation of forces:
∑F = -M₁gsinФ + T - T + M₂g
Simplify and solve for acceleration: (Tensions cancel out)
[tex]a = \frac{-M_1gsin\theta + T - T + M_2g}{M_1+M_2}[/tex]
Plug in values. Let g = 10 m/s²
[tex]a = \frac{-3(10)(sin30)+8(10)}{3+8} = 5.91 m/s^{2}[/tex]
Now, to find tension, let's sum up the forces acting on ONE block. For simplicity, we can look at the hanging block:
∑F = -T + W
ma = -T + W
Rearrange to solve for T:
T = W - ma
We know the acceleration, so plug in the values:
T = (8)(10) - (8)(5.91) = 32.73 N
Will give 45 points to who ever solves this
Answer:
1)m=230 kg
w= 2254( approximately 2300) newtons
g= 9.8 m/s^2(approximately 10)
2)m= 90.5( approximately 88.7) kg
w= 887 N
g= 9.8 m/s^2(approximately 10)
3) m= 420 kg
w= 4,116 (approximately 4220
g= 9.8 m/s^2(approximately 10)
4) m=15kg
w=55.5N
g=3.7 m/s^2
Explanation:
The wanswers given in brackets is to signify the results of using 10m/s^2 as the gravity if u have any misunderstanding text back

when is/was gravitational contraction an important energy generation mechanism for the sun?
Answer: It was important when the Sun was forming from a shrinking interstellar cloud of gas.
Hope this helps!!
This process is thought to have been the main source of energy for the sun in the early stages of its development before nuclear fusion reactions in the sun's core became the dominant source of energy.
What is Gravitational contraction?Gravitational contraction is the process by which a celestial body, such as a star, generates energy through the release of gravitational potential energy as it contracts and becomes denser.
Here,
This process is thought to have been the main source of energy for the sun in the early stages of its development before nuclear fusion reactions in the sun's core became the dominant source of energy.
As the sun contracted and became denser, the temperature and pressure in its core increased, leading to the initiation of nuclear fusion reactions. These reactions transformed hydrogen into helium and released a tremendous amount of energy in the form of light and heat, which has sustained the sun for billions of years.

You toss a tennis ball straight upward. At the moment it leaves your hand it is at a height of 1.5 m above the ground, and it is moving at a speed of 7.0 m/s.
(a) How much time does it take for the tennis ball to reach its maximum height? (s)
(b) What is the maximum height above the ground that the tennis ball reaches? (m)
(c) When the tennis ball is at a height of 2.4 m above the ground, what is its speed? (m/s)
a). 1.2 s
b). 3.81 m
c) v= 6.8 m/s
d) v= 27.05 m/s
What is speed?Speed is define as the distance per unit time. It is also define as how fast an object is moving.
According to the question:
Height = 1.5 m , speed = 7.0 m/s.
a)By using 1st equation of motion
[tex]V = V_{0} + g*t.\\V = 0 \\V_{0} = 7.0 m/s.g = -9.8 m/s^2\\0 = 7 + (-9.8 m/s^2)*t\\t = 1.2 s[/tex]
b.
[tex]h = 1.5 + V_{0} *t + 0.5g*t^2\\V_{0} = 7.8 m/s\\t = 1.2s , g = -9.8 m/s^2\\h = 3.81 m[/tex]
c.
[tex]V^2 = V_{0} ^2 + 2g*d\\V_{0} = 7.8 m/s\\g= -9.8 m/s^2.\\d= 2.2-1.5 = 0.7 m\\V = 6.8 m/s[/tex]
d.
[tex]V^2 = V_{0} ^2 + 2g*h\\V_{0} = 0\\g = +9.8 m/s^2.\\h = 6.8 m\\V = 27.05 m/s[/tex]
