Answer:

2 is the numerical answer.

Explanation:

Hello there!

In this case, according to the given information and formula, it is possible for us to remember that equation for the calculation of the average kinetic energy of a gas is:

KE=\frac{3}{2} \frac{R}{N_A} T

Whereas R is the universal gas constant, NA the Avogadro's number and T the temperature.

Which means that for the given ratio, we can obtain the value as follows:

=\frac{\frac{3}{2} \frac{R}{N_A} T_1}{\frac{3}{2} \frac{R}{N_A} T_2} \\\\=\frac{T_1}{T_2} \\\\=\frac{500K}{250K} \\\\=2

Regards!

nadezda [96]

Answer:

An increase in angular speed due to conservation of energy priciple.

Explanation:

This leads to a decrease in your moment of inertia. This means that your angular velocity must increase as a result of conservation of energy principle and therefore you will spin faster.

It's also the same way this conservation of energy principle applies to ice skaters that makes them spin faster when they suddenly draw their arms inwards.

Pure water has a hydrogen ion concentration of 1 x 10 (-7) M and a ph of 7. A student measures a basic solution and finds that i
Lena [83]

The student must have made an error in her measurement in the concentration of hydrogen ion in the basic solution given. From her measurement, the concentration is  1 × 10−3 M. If we calculate the pH, we get:

pH = -log ( 1 × 10−3) = 3

A pH of 3 does not signifies a basic solution it is in the acidic range. So, the measurement is wrong.

A helicopter (m = 3250 kg) is cruising at a speed of 56.9 m/s atan altitude of 185 m. What is the total mechanical energy of the
taurus [48]

Answer:

The mechanical energy of the helicopter is 1.12\times 10^7\ J.

Explanation:

It is given that,

Mass of the helicopter, m = 3250 kg

Speed of the helicopter, v = 56.9 m/s

Position of the helicopter, h = 185 m

The energy possessed by an object due to its motion is called its kinetic energy. It is given by :

E=\dfrac{1}{2}mv^2

E=\dfrac{1}{2}\times 3250\times (56.9)^2  

E=5.26\times 10^6\ J

The energy possessed by an object due to its position is called its potential energy. It is given by :

E=mgh

E=3250\times 9.8\times 185  

E=5.89\times 10^6\ J

The sum of kinetic and potential energy is called mechanical energy of the system. It is given by :

M=5.26\times 10^6+5.89\times 10^6

M=11.15\times 10^6\ J

or

M=1.12\times 10^7\ J

So, the mechanical energy of the helicopter is 1.12\times 10^7\ J. Hence, this is the required solution.
