I think it should be option (b)
Answer:
true
Explanation:
a wheelbarrow has its load situated between the fulcrum and the force the wheel Barrow is 2nd class because of its resistance between the force and the axis
Answer with Step-by -step explanation:
We are given that
b.
below the positive x-axis
Therefore, the angle made by vector A in counter clockwise direction when measure from positive x-axis=
x-component of vector A=
y-Component of vector A=
Magnitude of vector B=86 m
The vector B makes angle with positive x- axis=
x-component of vector B=
y-Component of vector B=
Vector A=
Vector B=
Vector C=A+B
Substitute the values


c.Direction=
The direction of the vector C=21.5 degree
This
B: False, because the definition
is lacking.
Force
is when two objects interact with one another causing it to either move or not
move. In our daily lives there are a lot of times force is exerted upon us,
rather force is everywhere and here are the evidences:
*Pushing
a cart
*Pushing
a wall
*Hitting
a baseball bat
*Apple
falling down from a tree.
*Balls
hitting one another
*A
swinging pendulum
*Throwing
a paper with stone above it
*Breaking
of glass in the floor
*Falling
of leaves on the grass

Ok, I think this is right but I am not sure:
Q = ϵ
0AE
A= π π
r^2
=(8.85x10^-12 C^2/Nm^2)
( π π (0.02m)^2)
(3x10^6 N/C) =3.3x10^-8 C = 33nC N = Q/e = (3.3x10^-8 C)/(1.60x10^-19 C/electron) = 2.1x10^11 electrons
