because its is being pulled by south and west it will travel south west.
In a forward bias, the p-type is connected to the positive side of the terminal and the n-type is connected to the negative terminal of the voltage source. The electrons in the n-type junction travels towards the holes in the p-type junction
In a reverse bias, the junctions are connected to the opposite terminals compared to the forward bias. The free electrons build up on the center creating a neutral layer that widens as voltage is increased.
Answer:
a) 6.4 kJ
b) 43.4 kJ
Explanation:
a)
= Heat absorbed = 37 kJ
= Coefficient of performance = 5.8
= Work done
Heat absorbed is given as
=
37 = (5.8)
= 6.4 kJ
b)
= work per cycle required
= +
= 37 + 6.4
= 43.4 kJ
Answer:
A = 150 cm at 120 degc
Where A + B = C find B
B = C - A add -A to both sides
Ax = 150 cos 60 = -75
Ay = 150 sin 60 = 129.9
Likewise
Cx = 114.7
Cy = 80.3
Bx = Cx - Ax = 114.7 + 75 = 189.7
By = Cy - Ay = 80.3 -129.9 = -49.6
B = (189.7^2 + 49.6^2)^1/2 = 196.7 length of B vector
tan B = By / Bx = -49.6 / 189.7 B = -14.65 deg
Also
sin B = By / B = -49.6 / 196.1 = -14.65 deg
So B is 196.1 cm at -14.65 deg
1.
Answer:
Hand on book
Earth on book
Explanation:
Since we are holding the book so the forces that acts on the book is
1. Hand on book
this is the contact force between hand and the book
2. Earth on book
here this is the gravitational attraction force of earth on the book
2.
Answer:
A. book on hand - NA
B. hand on book - upwards
C. floor on book - NA
D. earth on book - downwards
Explanation:
Since book is holding in hand so at equilibrium position we can say that the forces on the book must be in equilibrium
so first of all the force of attraction due to earth on the book is downwards and this is counterbalanced by the force of hand on book which is upwards.
3.
Answer:
A. book on hand
Explanation:
As per Newton's III law we know that every action has equal and opposite reaction.
so if our hand apply the force on the book in upward direction then book will apply same magnitude force on the hand in downward direction.
