The least number of component of a vector quantity is two. These are the x-component and the y-component.
The resultant vector, or vector as we refer to it in this item, can be calculated through the equation,
RV = sqrt ((Vx)² + (Vy)²)
From the equation, it can be noted that if we let Vx equal to zero,
RV = Vy
Similarly, if we let Vy be equal to zero then,
RV = Vx
Thus, it is still possible for the vector to become nonzero even if one of its components is zero.
Answer with Explanation:
Electric field:It is the force per unit charge experienced by rest charge at any given point.
It is the area around the charge which is placed at rest.It is represented by E.
Mathematical formula:

Magnetic field:It is an area around moving charge in which moving charge particle experienced magnetic force in that area.
Magnetic field is represented by B.
Mathematical formula :

Where B=Magnetic field
q=Charge on particle
v=Velocity of particle
F=Magnetic force exert on particle
Answer:
179 degree
Explanation:
Solid copper will lose heat to warm up and melt ice . Since all the ice has not melted so final temperature of mixture will be zero.
heat gained by ice to reach temperature of zero degree
= mass of ice x specific heat of ice x rise of temp
= 2 x 2093 x 16 = 66976 J
Heat gained to melt 1.1. kg of ice
mass x latent heat of ice
1.1 x 334000
= 367400
total heat
= 367400 + 66976
=434376
Heat lost by copper
= 6.3 x 385 x T
where 385 is specific heat of copper and T is initial temperature
heat lost = heat gained
6.3 x 385 T = 434376
T = 434376 / (6.3 x 385)
= 179 degree .
