Answer:
as we find the resultant of the magnetic field we get in the xy plane. Just perpendicular to this plane i.e. along z-axis the charge is moving. Hence the force acting on the charge will also be in the xy plane.
Net field = ./(0.078^2 +0.070^2) = 0.105 T
Angle with x axis is arc tan 0.070/0.072 = 44.2 deg
So the force acting on the moving charge is got by Bqv
0.105*5.5*10^-5 * 6*10^3 = 0.03465 N
So the angle inclined by this force with x axis will be 90+44.2 = 134.2
Explanation:
It must have a medium to travel through.
Happy to help. Marking me the brainliest would really be appreciated.
Answer:
<h2>The period is 0.04 sec</h2>
Explanation:
This problem is based on oscillatory motion.
What is the period of oscillation?
This can be defined as the time taken to complete one full revolution or oscillation.
given that the fly flaps its wings back and forth 25 times in one second. then the frequency is 25 Hz
we know that period T= 1/F
T= 1/25
T=0.04 sec
Answer:
C
Explanation:
It is the atomic number that constantly goes up on the periodic table
An excited atom can return to its ground state by absorbing electromagnetic radiation is false about the electromagnetic radiation.
Option B
<u>Explanation</u>:
In the scope of modern quantum theory, the term Electromagnetic radiation is identified as the movement of photons through space. Almost all the sources of energy that we utilize today such as coal, oil, etc are a product of electromagnetic radiation which was absorbed from the sun millions of years ago.
Various properties of electromagnetic radiations are a directly proportional relationship between the energy and the frequency, Inverse proportionality between frequency and the wavelength, etc. Hence, we can conclude that an "excited atom" can never return to its ground state by assimilating electromagnetic radiation and the 2nd statement is false.
