So, If the resistance decreases, then the current increases. Assume voltage is constant.

If the voltage increases, then the current increases. Assume resistance is constant.

Explanation:

According to the ohm's law; I = V/R;

If the resistance decreases the current increases assuming that the voltage is constant
if the voltage increases, then the current increases assuming that the resistance is constant.

Based on Ohm's law, we know that the current through a metallic conductor is directly proportional to the voltage across the ends.

From the relationship;

I = $\frac{V}{R}$

we see that V = IR

These equations affirms that

If the resistance decreases the current increases assuming that the voltage is constant based on the second equation

if the voltage increases, then the current increases assuming that the resistance is constant based on the first equation.

A mass m is attached to an ideal massless spring. When this system is set in motion with amplitude a, it has a period t. What is

Luden [163]

The period will be the same if the amplitude of the motion is increased to 2a

What is an Amplitude?

Amplitude refers to the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Here,

mass m is attached to the spring.

mass attached = m

time period = t

We know that,

The time period for the spring is calculated with the equation:

$T = 2\pi \sqrt{\frac{m}{k} }$

Where k is the spring constant

Now if the amplitude is doubled, it means that the distance from the equilibrium position to the displacement is doubled.

From the equation, we can say,

Time period of the spring is independent of the amplitude.

Hence,

Increasing the amplitude does not affect the period of the mass and spring system.

ycow [4]

Answer:

$\large\boxed{\large\boxed{10ft/s}}$

Explanation:

The question, translated, is:

A steel ball rolls and falls off the edge of a table from 4ft above the floor. If you hit the ground 5ft from the base of the table, what was your initial horizontal velocity?

<h2>Solution</h2>

This is a projectile motion, for which, the equations that you will need are:

$V_x_0= V_x=x\cdot t$
