Answer:
Induced emf in the coil,
Explanation:
Given that.
Number of turns in the coil, N = 200
Side of square, d = 18 cm = 0.18 m
The field changes linearly from 0 to 0.50 T in 0.80 s.
To find,
The magnitude of the induced emf in the coil while the field is changing.
Solution,
We know that due to change in the magnetic field, an emf gets induced in the coil. The formula of induced emf is given by :
= magnetic flux
A is the ares of square
So, the induced emf in the coil is 4.05 volts. Hence, this is the required solution.
Answer:
0.78m/s
Explanation:
Now the momentum ensued by the boy throwing the package Is
Mass of package × velocity of package =4.5×13=58.5m/s
This momentum initiated a momentum on the boy-boat system
Total mass of the boy-boat system is 24+53=75kg
Let the velocity ensued by the boat be v.
Hence from conservation of momentum
58.5 =75×v
v= 58.5/75= 0.78m/s
Answer:
1.6 pF
Explanation:
The capacitance of a parallel-plate capacitor in air is given by:

where
is the vacuum permittivity
A is the area of each plate
d is the separation between the plates
In this problem we have:
- Separation between the plates: d = 5.00 mm = 0.005 m
- Area of the plates: 
Therefore, the capacitance is

Answer:
Answer :- In a light wave the property of wave which tells about the color of light is it's Wavelength .
Wavelength is the distance between one crest and one through , also it is the distance after which the wave repeat itself !
It's SI unit is meter !
It is scalar quantity !!
Different Wavelength of light have different color !!
• VIBGYOR
i.e, Violent , Indigo , Blue , Green , Yellow Orange, and Red along with their shades are the colors which we can see !!
• They almost range from 400nm to 700nm ( visible range of light ) !!
The process that explains why one part of the earth's surface is arid and dry and a nearby part is lush and wet is areal differentiation. It is<span> an approach to geography that shows </span>the dependence of the distribution of physical and human phenomena and the relation to each other from the physical location. Areal integration on the other hand is the approach that studies how places interact with each other.
