Answer:
35 Joules
Explanation:
Applying
Input Energy(Q) = Useful energy output(U)+Wasted Energy(W)
Q = U+W.............................. Equation 1
Make U the subject of the equation
U = Q-W................... Equation 2
From the question,
Given: Q = 120 Joules, W = 85 Joules
Substitute these values into equation 2
U = 120-85
U = 35 Joules
On the off chance that u know the condition I = NEVA where N= no. thickness of electrons, E= charge on a solitary electron, V=drift speed ,and A=area of cross-segment.
since the widths are same , the zone of cross-segment must be same and thusly the float speed likewise will be the same
b) as u know current streams from higher to bring down potential.The electrons will spill out of lower potential to higher potential. Higher potential suggests higher potential vitality and accordingly potential vitality must increment.
Answer:
Explanation:
Coordinate system is one that describe the location of an object in a given plane. It implies the use of axes (coordinates) and points.
Given that the man in the question walks 400 m due north of east. The cardinal points can be used in this case, with the north and east cardinals as the required axis.
scale =
=
=
scale = 1:40
This is a reduced scale which implies that 1 cm on the drawing is equal to 40 m on the original length.
The man's direction is north of east.
The graphical drawing of the vector is herewith attached to this answer.
