Answer:
22.5 miles due North
38.7 miles due East
Explanation:
From the information given above, we infer :
Let there be a <u>vector <em>AB</em></u><em> </em>(indicating distance travelled) with <em><u>magnitude = 45 </u><u>mi</u></em><u> </u> and makes an angle of <em>30° with East axis</em> as well as an angle of <em>60° with North axis</em>.
<u>Displacement covered in North Direction </u><u>:</u>
AB Cos 60° = <em><u>22.5 miles due North </u></em>
<u>Displacement covered in East Direction</u> :
AB Cos 30° = <em><u>38.7 miles due East</u></em>
Answer:
option (a)
Explanation:
To make a galvanometer into voltmeter, we have to connect a high resistance in series combination.
The voltmeter is connected in parallel combination with teh resistor to find the voltage drop across it.
An ideal voltmeter has very high resistance that means it has a resistance as infinity.
Answer:
3.2m
Explanation:
Given parameters:
Frequency of the FM radio = 9.23 x 10⁷Hz
Velocity of the waves = 3 x 10⁸m/s
Unknown:
Wavelength of the wave = ?
Solution:
To solve for the wavelength of the wave, we need the velocity equation;
Velocity = frequency x wavelength.
Radio waves are all electromagnetic radiations produced by both electrical and magnetic fields perpendicularly oriented to one another.
Since the unknown is wavelength, we solve for it:
3 x 10⁸ = 9.23 x 10⁷ x wavelength
wavelength =
wavelength = 3.2m
Explanation:
SI system is advantageous over mks system because SI system is intended to extend by its definition and has 7 base which is more than MKS system .
