A vessel that contains a gas has two pressure gauges attached to it. One contains liquid mercury, and the other an oil such as d

ibutyl phthalate. The difference in levels of mercury in the two arms of the mercury gauge is observed to be 9.50 cm.
Given density of mercury is 13.60 g cm², density of oil is 1.045 g cm², acceleration due to gravity is 9.806 m s².
(a) What is the pressure of the gas?
(b) What is the difference in height of the oil in the two arms of the oil pressure gauge?

Answer:

Pressure of the gas = 12669 (Pa) and height of the oil is 1,24 meters

Explanation:

First, we can use the following sketch for an easy understanding, in the attached image we can see the two pressure gauges the one with mercury to the right and the other one with oil to left. We have all the information needed in the mercury pressure gauge, so we can determine the pressure inside the vessel because the fluid is a gas it will have the same pressure distributed inside the vessel (P1).

Since P1 = Pgas, we can use the same formula, but this time we need to determine the height of the column of oil in the pressure gauge.

The result is that the height of the oil column is higher than the height of the one that uses mercury, this is due to the higher density of mercury compared to oil.

Note: the information given in the units of the fluids is not correct because the density is always expressed in units of (mass /volume)

A light bulb is rated at 25 w when operated at 110 v. how much charge enters (and leaves) the light bulb in 1.0 hour?
DedPeter [7]

According to the current, the charge is 818.18 coulombs.

We need to know about current to solve this problem. Current can be defined as the flow rate of charge through the medium. It can be determined as

I = Q / t

where I is current, Q is charge and t is time.

From the question above, we know that

P = 25 W

V = 110 V

h = 1 hour = 3600 second

Calculate the current

P = V . I

25 = 110 . I

I = 0.23 A

By substituting the given parameters, we can calculate the charge

I = Q / t

0.23 = Q / 3600

Q = 818.18 coulombs

Hence, the charge is 818.18 coulombs.

Which factors affect gravitational force? Check all that apply.
alina1380 [7]

Answer:

distance between the objects

masses of the objects

Explanation:

Gravitational force is a force of attraction that pulls two objects with masses together.

To best understand the concept of gravitational force, newton's law of universal gravitation provides a good insight. The law states that "every object in the universe attracts each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distances between them".

From the law, we see that gravitational force is dependent on the masses of the object and their distances.

Squids rely on jet propulsion to move around. A 1.50 kg squid (including the mass of water inside the squid) drifting at 0.40 m/
yanalaym [24]

Answer:

-22.5 m/s

Explanation:

m_1 = Mass of squid = 1.5 kg

m_2 = Mass of water ejected = 0.14 kg

v_1 = Velocity of squid = 0.4 m/s

v_2 = Velocity of squid after ejection = 2.5 m/s

v = Velocity of water ejection

In this system the momentum is conserved

m_1v_1+(m_1-m_2)v_2+m_1v=0\\\Rightarrow 1.5\times 0.4-2.5(1.5-0.14)-1.5v=0\\\Rightarrow v=\frac{-1.5\times 0.4+(1.5-0.14)\times 2.5}{-0.14}\\\Rightarrow v=-20\ m/s

The velocity of the water ejection relative to the squid is

-20+(-2.5) = -22.5 m/s

The negative sign indicates the opposite direction to the direction of the squid.
