Answer:

Explanation:
F₁ = Force on one side of the jack
A₁ = Area of cross-section of one side of the jack
F₂ = Force on second side of the jack
A₂ = Area of cross-section of second side of the jack = 2 A₁
Using pascal's law




Answer:
converts high-voltage, low-current power into low-voltage, high-current power.
Explanation:
Answer:
the distance of the top of the window below the windowsill from which the flowerpot fell is 0.31 m
Explanation:
given information:
time, t = 0.420 s
height, h = 1.9 m
the the vertical motion equation:
h =
t + 
where
h = height (m)
= initial velocity (m/s)
t = time (s)
g = gravitational force (9.8
)
first we calculate the velocity of the flowers pot when it reaches top window
h =
t + 
1.9 =
(0.42) + (
)
= (1.9 - (
))/0.42
= 2.47 m/s
now we can find the distance of the windowsil
+ 2gh
v = 0, thus
2gh = - 
h = -
/2g
=
/ (2 x 9.8)
= 0.31 m
Answer: To convert this into dimes it's basically like 25 divided by 10.
25 / 10 = 2.5, So you'd need two dimes and a nickel.
It’s mass is 100 kg, because if you divide both numbers, you get 100
