Answer:

Explanation:

Given

there is fix Quantity of gas i.e. mass of gas is constant

From ideal gas Equation

PV=nRT

(a) volume always increases is not true as Pressure can also be increased .

(b)If Pressure is constant along with mass then as Temperature increases, Volume also increases.

(c)true , Product of Pressure and volume depends upon temperature thus it also increases with temperature.

(d)Density of gas may or may not increases

As density is \frac{mass}{volume}

volume may increase or decrease as temperature increase .

(e)false

as it clearly stated that quantity of fixed therefore there is no change in gas

Marizza181 [45]
Using the pressure law (P1 x V1)/ T1 = (P2 x V2)/ T2 where P1= the initial pressure V1= initial volume T1= initial temperature and P2= the final pressure V2= the final volume T2 = the final temperature and temperature is always in kelvin

You pull on a crate with a rope. If the crate moves, the rope's pull on the crate must have been larger than the crate's pull on
GalinKa [24]

Answer:

the  affirmation  is False

Explanation:

This expression can be analyzed using Newton's laws and specifically Newton's third law that establishes that the force that one body (1) exerts on another body (2) is of the same magnitude as the force exerted by the second body on the first, but in the opposite direction.

Based on this law, the body applies a force to the box and the box reacts with a force on the string of equal magnitude, no matter if it is moving or not, but it  contrary direction,

in view of this explanation the  affirmation  is False

3. If a 50-kg person is running at 2 m/s and a 25-kg person is running at twice
lubasha [3.4K]

Answer:

The two people have the same momentum.

Explanation:

Given that,

Mass of person 1 is 50 kg and he is running at 2 m/s.

Mass of person 2 is 25 kg and he is running at twice  that speed i.e. 4 m/s

The momentum of an object is given by :

p = mv

For person 1,

p=50\times 2\\\\p=100\ kg-m/s

For person 2,

p'=25\times 4\\\\p'=100\ kg-m/s

So, it can be seen that both persons will have the same momentum. Hence, the correct option is (c).

Why did you need a permanent magnet? What do you think would happen if you increased the
inysia [295]

Permanent magnets are important for their industrial uses especially when it comes to power generation and electric motors. The induction process for turbines and generators needs permanent magnets to turn mechanical motion into energy.

Exposing magnetized magnets to opposing external fields produces a demagnetizing effect. This effect is most apparent in permanent magnet materials having a non-linear demagnetization curve, such as Alnico. ... Other factors such as SHOCK and VIBRATION have very little effect on today's permanent magnet materials.
