Is directly proportional to the length and resistivity of the conductor.
2 answers:
The resistance of conductor is directly proportional to length and resistivity.
Answer: Option B
<u>Explanation: </u>
Resistance is present in an electrical object or rather introduced to counter check the flow of the current. It is similar to the mechanical friction in the conceptualization of its existence and effect.
It is directly proportional to the length of the electric circuit. It is being measured and noted in ohm. The formula for resistance is –
Where,
R - the Resistance of the wire,
- the resistivity of the wire
L - The length of the wire
A - the area of cross section of the wire

The range of the projectile is 188 m
Explanation:
The motion of the arrow in this problem is a projectile motion, so it follows a parabolic path which consists of two independent motions:
- A uniform motion (constant velocity) along the horizontal direction
- An accelerated motion with constant acceleration (acceleration of gravity) in the vertical direction
The path of a projectile is the combination of these two motions: see figure in attachment.
In order to find the horizontal range of the projectile, we just need to calculate the horizontal distance travelled.
We have:
t = 5.0 s (time of fligth of the projectile)
and the horizontal velocity is constant, and it is given by
where
is the initial velocity
is the angle of projection
Substituting,
And therefore, the range of the projectile is:
