How many moles of h2 gas would be contained in 4.00 of the gas at 202.6KPa and 127c?

Physics
1 answer:
JulsSmile [24]3 years ago
4 0

Answer : The volume of one mole of gas is dependent of temperature and pressure.

Explanation:

At <span><span>0o</span>Cand1atm</span> one mole of an ideal gas would be <span>≈22.4L</span>, which is the same as <span>22.4d<span>m3</span></span>

If you double the pressure, the same amount (mole) of gas would take up only half the space.

If the temperature changes (and pressure stays constant), the gas will expand or contract by about <span>1%/<span>3o</span></span>.

When applying a horizontal force of 30N, an object of mass 6 kg accelerates at 4m/s2. The force of friction on the surface must
Rus_ich [418]
Using Newton's Second Law, F = ma, where F is the net force

So the net force is:

F = (6kg)(4m/s^2) = 24N

Since you are applying a horizontal force of 30N, we can find the force of friction by the difference of the net force and the applied force.

30N-24N = 6N

F_{f} = 6N

2) What must be connected for an electrical current to flow in a simple current?
hjlf

2) What must be connected for an electrical current to flow in a simple current?

<em>d.moving magnets,conductors, load to do work </em>

here moving magnets will work as generator and conductors is used as connectors.

5)What is the purpose of a load in a circuit?

<em>c.provide resistance to keep the voltage strong </em>

Load will provide the resistance to the circuit and help to build the voltage across it

6) What cause an electric current from a generator

<em>d.Magnets and conducting wires move near each other </em>

here when magnets move near wires then it will induce the electric current and behaves like generators

7) What do all generators have in common

<em>b.they transform mechanical into electrical energy </em>

They have magnets and rotating coils which will convert magnetic energy to electrical energy

8) How can we measure electrical current

<em>b.the pressure force is voltage;the # of electrons moving is amperes </em>

this voltage and number of electrons will help to calculate current

How much work output can a 150hp snowmobile do in 15 seconds if it is 18 % efficiency?
Sav [38]

The work output is 3.02\cdot 10^5 J

Explanation:

The power of the snowmobile is

P=150 hp

Keeping in mind that

1 hp = 746 W

We can convert it into Watts:

P=(150)(746)=111,900 W

The energy used by the snowmobile can be found as follows:

E=Pt

where

P = 111,900 W is the power used

t = 15 s is the time interval

Substituting,

E=(111,900)(15)=1.68\cdot 10^6 J

However, the snowmobile is 18% efficient: this means that only 18% of this energy is converted into useful work. Therefore, the work output is

W=0.18E=(0.18)(1.68\cdot 10^6)=3.02\cdot 10^5 J
