In the Boyle’s law experiment, what was used to increase the pressure on the air (gas)?

MA_775_DIABLO [31]

Answer:

Volume.

Explanation:

Boyle’s law experiment :

This is also known as Mariotte's law or in the other words it is also known as Boyle–Mariotte law.

This law tell us about the variation of gas pressure when the volume of the gas changes at the constant temperature.According to this law the abslute pressure is inversely proportional to the volume .

We can say that

$P\alpha \dfrac{1}{V}$

Where P=Pressure

V=Volume

PV = K

K=Constant

When volume decrease then the pressure of the gas will increase.

That is why the answer is "Volume".

A student removes a 10.5 kg stereo amplifier from a shelf that is 1.82 m high. The amplifier is lowered at a constant speed to a

Nonamiya [84]

Answer:

(a) the work done by the student is 110.1 J

(b) The gravitational force that acts on the amplifier is 102.9 N

Explanation:

Given;

mass of the amplifier, m = 10.5 kg

initial position of the amplifier, x₀ = 1.82 m

final position of the amplifier, x₁ =0.75 m

The dispalcement of the amplifier Δx = x₁ - x₀ = 1.82 m - 0.75 m = 1.07 m

(b) The gravitational force that acts on the amplifier;

F = mg

F = 10.5 x 9.8

F = 102.9 N

(a) the work done by the student is calculated as;

W = FΔx

W = 102.9 x 1.07

W = 110.1 J

A large ant is standing on the middle of a circus tightrope that is stretched with tension T_s. The rope has mass per unit lengt

k0ka [10]

Answer:

$A = \frac{g \lambda^2 \mu}{4\pi^2 T_s}$

Explanation:

As we know that the speed of the wave in string is given as

$v = \sqrt{\frac{T_s}{\mu}}$

now we will have

frequency of the wave is given as

$f = \frac{v}{\lambda}$

$f = \frac{1}{\lambda}\sqrt{\frac{T_s}{\mu}}$

now if the ant will feel weightlessness then we will have

$mg = m\omega^2 A$

so we will have

$A = \frac{g}{\omega^2}$

$A = \frac{g}{4\pi^2 f^2}$

$A = \frac{g \lambda^2 \mu}{4\pi^2 T_s}$

Ryan applied a force of 10N and moved a book 30 cm in the direction of the force. How much was the workdone by Ryan?

Orlov [11]

Force=10N
Displacement=30cm=0.3m

$\\ \sf\bull\longmapsto Wd=Force(Displacement)$

$\\ \sf\bull\longmapsto Work=10(0.3)$

$\\ \sf\bull\longmapsto Work=3J$
