Answer:
The length of the wire is "1.93 m".
Explanation:
Given:
Current,
I = 0.66 A
Angle,
= 58°
Magnetic field of magnitude,
F =
N
The length of the wire will be:
⇒ 
or,
⇒ 
By putting the values, we get



Answer:
Area is a scalar quantity because there is no need of direction to define and also follow the algebraic summation. When we talk about vector there exists a frame of reference with a certain origin. It actually depends on the fact of the physical area, but if that factor changes to a non-directional object such as a rug spread on the floor, you can consider the area or a region as a scalar. (*Scalars are quantities that are fully described by a magnitude (or numerical value) alone.)
Hope this helps!
First calculate the time it would take for the crate to
fall using the formula:
h = v0 t + 0.5 g t^2
110 m = 0 + 0.5 (9.8 m/s^2) t^2
t = 4.74 s
The crate is also moving at 46 m/s on with respect to the
horizontal surface, therefore distance covered is:
d = (46 m/s) * 4.74 s
d = 217.95 m
The crate would fall 217.95 m from the tail of the car.
if spring constant is doubled, the mass on spring will be doubled as well. according to this formula, F=ke
k stands for spring constant and e stands for the length extended
