In which it is the plane in which charges move. for example in electromagnetic waves polarization<span> means the plane in which electrons oscillate. ... it is the distribution of electric charges (electron) in an object. </span>induction<span> of charges takes place in some insulators just by some mechanical interaction such as rubbing</span>
Answer:
(a) Current will be
(b) Number of ions will be
Explanation:
We have given that resistance of the biological cell
(a) We have given potential difference of 75 mV
So
From ohm's law we know that current is given by
(b) We have given time t = 0.74 sec
We have to find the charge
We know that charge is given by Q = it, here i is current and t is time
So charge will be
So number of ions will be
A basic mechanical device that is used for applying a force.
Examples are: inclined plane, lever, wedge, wheel and axle, pulley, and screw...Hope this helps, have a BLESSED and wonderful day!
The <u>apparent magnitude</u> of a star refers to its brightness as seen from your eyes and <u>absolute magnitude</u> being the actual brightness of a star.
<h3>What is magnitude?</h3>
Magnitude can be defined as a unitless measure which is used to show the brightness of an object in comparison with the brightness of another object.
Basically, there are two types of magnitude and these include the following:
In conclusion, the <u>apparent magnitude</u> of a star refers to its brightness as seen from your eyes and <u>absolute magnitude</u> being the actual brightness of a star.

Answer:
Fa=774 N
Fb=346 N
Explanation:
We will solve this problem by equating forces on each axis.
- On x-axis let forces in positive x-direction be positive and forces in negative x-direction be negative
- On y-axis let forces in positive y-direction be positive and forces in negative y-direction be negative
While towing we know that car is mot moving in y-direction so net force in y-axis must be zero
⇒∑Fy=0
⇒
⇒
⇒
Given that resultant force on car is 950N in positive x-direction
⇒∑Fx=950
⇒
⇒
⇒
⇒
⇒
⇒
⇒
Therefore approximately, Fa=774 N and Fb=346 N
