Answer:

It will be more than deta t

Explanation:

Because

deta t' = န deta t

But န= 1/√ (1 - v²/c²

At constant pressure, a sample of a gas occupies 420 ml at 220 K. what volume does the gas occupy at 250 K?
soldier1979 [14.2K]

Answer:

480 mL

Explanation:

Ideal gas law states:

PV = nRT

At constant pressure, nR/P is constant.  Therefore:

V / T = V / T

420 mL / 220 K = V / 250 K

V ≈ 480 mL

Rearranging the equation m= 5Kg and a= 2 m\s2
olganol [36]

The force of the object with the given mass and acceleration is determined as 10 N.

<h3>Force of the object</h3>

The force of the given object is calculated from Newton's second law of motion as follows;

F = ma

where;

  • m is mass of the object = 5 kg
  • a is acceleration of the object = 2 m/s²

F = 5 x 2 = 10 N

Thus, the force of the object with the given mass and acceleration is determined as 10 N.

The complete question is below:

Rearranging the equation m = F/a and solve for F, m= 5Kg and a= 2 m\s2

A hydraulic machine can be used to lift extremely heavy objects. Why is the fluid in the hydraulic machine a liquid rather than
Sauron [17]
Hi,

The force that acts on hydraulic machine is heavy therefore the content must be something that cannot be compressed by that kind of force, the gas can easily be compressed while a liquid is nearly impossible to.
