<span> radio: longitudinal, light: transverse. x rays are produced by voltage and they are more penetrating Gamma Xrays Ultrasound Visible light Infrared Radiowaves. that is the order. colours are different since they absorb part of the colour spectrum & emit the rest </span>
Answer:
Explanation:
Resultant of two forces, F = 8 N
It is required to find the angle between two forces. The resultant of two force is given by the :
is the angle between F₁ and F₂
So,
So, the angle between two forces is 165 degrees.
The answer is c. More would be making a comparison. :)
Answer:
W=0.94J
Explanation:
Electrostatic potential energy is the energy that results from the position of a charge in an electric field. Therefore, the work done to move a charge from point 1 to point 2 will be the change in electrostatic potential energy between point 1 and point 2.
This energy is given by:
So, the work done to move the chargue is:
The work is positive since the potential energy in 1 is greater than 2.
Explanation:
To find the answer use the equation speed of light=wavelength multiplied by frequency (c=lambda*f) by substituting the value for the frequency the the speed of light
