If the magnetic field in a traveling EM wave has a peak value of 17.9nT, what is the peak value of the electric field strength?
Doss [256]

Answer:

5.37 N/C

Explanation:

Peak value of magnetic field, Bo = 17.9 nT = 17.9 x 10^-9 T

The electromagnetic wave is produced when an oscillating electric and magnetic field interacts each other perpendicularly.

The direction of propagation of electromagnetic wave is perpendicular to both electric and magnetic field.

the relation between the electric field and magnetic field amplitudes is given by

c = \frac{E_{0}}{B_{0}}

where, c be the velocity of light, Eo be the peak value of electric field strength, Bo is the peak value of magnetic field strength.

3\times 10^{8} = \frac{E_{0}}{17.9\times 10^{-9}}}

Eo = 5.37 N/C

How does universal gravitation affect you and objects around you?
Olegator [25]

<u>Answer</u>:

Newton proposed the "law of Universal Gravitation". He said that gravity is universal in nature and it affects all the objects. Gravity is present between you and every object having mass around you. The "Strength of the gravity" between two objects with mass is depends on the product of masses and distance between the objects.

The "Gravitational force" increases with the increase in mass of the objects and decreases with the increase in distance between the objects. The gravity exerts a force on every object. The direction of force of gravity is towards the centre of the Earth.

A circut contains a 2 microfarads and a 20 microfarads capacitor connected in parallel. What is the total capacitance of the cir
garik1379 [7]
The answer to this question would be:C. 22mf

In this question, there are two capacitors that connected in parallel. The formula to count the capacitor is the opposite of the formula used for the resistor. If constructed in series, the capacitor will have reduced capacitance. For parallel condition the equation would be:

Ctotal= C1+C2
C total= 2 mf+ 20mf= 22mf
