The average kinetic energy of a gas particle is directly proportional to thetemperature. An increase intemperature increases the speed in which the gas molecules move. Allgases at a given temperature have the same average kinetic energy. Lightergas molecules move faster than heavier molecules.
We have negative acceleration when an object projected upwards, while positive acceleration is a free fall.
Solution:
Formula for finding wavelength from frequency is wavelength=wave velocity(c)/frequency(f).
General value of Wave velocity (c) = 3 x 10^8 m/s
Given frequency = 2.0 x 10^6 Hz
Now,
Wavelength = 3 x 10^8 m/s / 2.0 x 10^6 Hz
= 150 m
Therefore the value of wavelength is 150m.
Explanation:
The atmosphere is heated in several ways - heat from the core of the Earth, by radiation from the Sun, conduction from contact with warm land and water, convection to even out the temperature and by absorption of infrared radiation from the warm land and water. The core of the Earth is very hot.
Answer:
The height of the water above the hole in the tank is 58 mm
Explanation:
In order to solve this problem we need to draw a sketch of the dimensions that include the input variables of the problem.
Where:
x = 0.579[m]
y = 1.45 [m]
Using the following kinematic equation we can find the time that takes the water to hit the ground, and then with this time, we can find the velocity of the water in the x-component.
It is necessary to clarify the value of each of the respective variables below
y = - 1.45 [m] "It is negative because this point is below the water outlet"
yo = 0
vo = 0 "The velocity is zero because the component of the speed on the Y-axis does not exist"
therefore:
The next step is to determine the velocity in component x, knowing the time.
Now using torricelli's law we can find the elevation.
