Answer:
<em>12 m/s</em>
Explanation:
<u>Projectile Motion</u>
It's also known as 2D motion because the movement takes place in both axis x and y. The x-axis motion is at a constant speed since in absence of friction, no external force stops or accelerates the object. The y-axis motion is at variable speed, which is changed by the acceleration of gravity that makes the object to reach a maximum height and then go back to ground level.
The maximum horizontal distance reached (also called Range) is given by

Knowing that
, we solve for Vo


Thus, the initial speed of Mike Powell was 12 m/s
The type of transformer that is found outside a residential house is :
step-down transformer
In step-down transformer, the secondary voltage is less than the primary voltage, which will reduce the voltage from the primary win.
Answer:
It is Conductivity because it is the measure of the ease.
