What is the relationship between resistance and current in a circuirt?

The relationship between resistance and current in a circuit is that if either resistance or current increase, then voltage increases; or vice versa for that matter. Another part in their relationship, is that resistance multiplied by current equals voltage so in order to calculate voltage, you must have resistance and current. I hope this helps!

A projectile is fired upward at an angle θ above the horizontal with an initial speed v0. At its maximum height, what are its ve
aliya0001 [1]

Answer:

\vec{v}_{\rm max} = v\cos(\theta)(\^x)\\|\vec{v}_{\rm max}| = v\cos(\theta)\\\vec{a} = \vec{g} = -9.8\^y

Explanation:

The equations of kinematics will be used to solve this question:

y - y_0 = v_{y_0}t + \frac{1}{2}a_yt^2\\v_y^2 = v_{y_0}^2 + 2a_y(y - y_0)\\v_y = v_{y_0} + a_yt

At its maximum height, the projectile has zero velocity in the y-direction. But its velocity in the x-direction is unaffected.

First, let's apply the above equations to the x-direction.

There is no acceleration in the x-direction. So, its velocity in the x-direction is constant during the motion.

v_x = v_{x_0} + a_xt = v_{x_0} + 0\\v_x = v_{x_0} = v\cos(\theta)

Therefore, the velocity vector of the projectile is

v_{max} = v_x = v\cos(\theta)

The speed of the projectile is the same.

The acceleration vector is constant during the motion and equal to the gravitational acceleration, which is -9.8 downwards.
