Answer:
∴The air cannot be made to flow in with the given pump at the given conditions.
Explanation:
Given:
- gauge pressure of bicycle tyre,
- length of cylinder of the pump,
- area of the the cylinder of the pump,
- we have the density of air at STP,
The piston must be pushed more than the pressure inside the tyre:
∴The air cannot be made to flow in with the given pump at the given conditions.

Explanation:
Coating surfaces with oil reduce friction between the surfaces because it is like when lubricating a machine, it makes it run or it makes it become smoother.
Answer:
power = 384.92 W
Explanation:
given data
resistance = 44.0 Ω
impedance = 71 Ω
ΔVrms = 210 V
to find out
average power
solution
we know here power formula that is
power = cos∅ .........1
we know here cos∅ =
cos ∅ = = 0.6197
so from equation 1
power = × 0.6197
power = 384.92 W
Yes, you are pulling on the Earth, with equal force.
Your weight on Earth is equal to the Earth's weight on you.
I can't think of a way for you to go out and see it or measure it,
but there are two things we learn in Physics that tell us that it
must be true.
#1). Newton's 3rd Law of motion:
For every action, there is an equal, opposite reaction.
If the Earth pulls on me, then I must pull on the Earth with an
equal, opposite force.
#2). Newton's law of universal gravitation:
Gravitational force = (a Constant) · (mass₁) · (mass₂) / (distance)² .
Take a good, long, hard look at this formula for the gravitational force.
It tells the strength of the gravitational force between the Earth and you.
But it doesn't say WHICH object is (mass₁) and which object is (mass₂) !
It doesn't matter ! BOTH objects feel the same gravitational force !
The nut distance from the Bullwinkle after uniform motion is 21 m.
We need to know about the uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule
vt = vo + a . t
vt² = vo² + 2a . s
s = vo . t + 1/2 . a . t²
where vt is final velocity, vo is initial velocity, a is acceleration, t is time and s is displacement.
From the question above, the parameters given are
m = 0.5 kg
s = 15 m
vx = 12 m/s
vo = 0 m/s
a = g = 9.8 m/s²
Find the time taken of the nut for landing
s = vo . t + 1/2 . a . t²
15 = 0 + 1/2 . 9.8 . t²
t² = 3.06
t = 1.75 s
Find the distance of nut in horizontal direction
vx = x / t
12 = x / 1.75
x = 12 . 1.75
x = 21 m
