4 0

Answer:

9.6m/s

Explanation:

Using the equation S=d/t where s=speed, d=distance, and t=time

plug in the known variables

S=120m/12.5s

S=9.6m/s

Suppose Person A runs off the edge of the cliff at 2 m/s and Person B runs off the edge at 1 m/s. Which will hit the ground fart
djverab [1.8K]

Answer:

<h2>Person A will hit a distance father</h2>

Explanation:

Based on the fact that the velocity of person A is more than that of person B, that is from the question, person A has a velocity of 2m/s and person B has a velocity of 1m/s, this clearly shows that person A has the tendency to hit a distance farther from the cliff than person B.

What is the energy stored in the 10.5 μ F 10.5 μF capacitor of a heart defibrillator charged to 8250 V ?
Kay [80]

Answer:

356.33 J

Explanation:

Energy: This can be defined as the ability or the capacity to do work. The S.I unit of Energy is Joules (J).

The Energy stored in a capacitor = 1/2CV²

E = 1/2CV².............................. Equation 1.

Where E = Energy stored in a capacitor, C = capacitance of the capacitor, V = potential difference across the plates of the capacitor.

Given: C = 10.5 μF  = 10.5×10⁻⁶ F, V = 8250 V.

Substitute into equation 1

E = 1/2(10.5×10⁻⁶)(8250)²

E = 357.33 J.

Thus the energy stored in the defibrillator = 356.33 J
