jeremie ran around the track at the ymca for 2 hours. when he was done he figured that he had traveled 20 kilometers. what was h
laila [671]
(1) Speed is the ratio of the total distance covered by the object and the total time it takes for him to finish it. 

    Speed = distance / time 

In this item, we are given that the distance is 20 kilometers and that the time it takes for the trip is 2 hours. Substituting the known values,
   Speed = 20 kilometers / 2 hours 
    speed = 20 km/h

(2) Velocity on the other hand takes into account the displacement of the object from his original position. It is assumed that Jeremie was basically back to his original position after two hours. Hence, the velocity is equal to zero.

The capacitance of a capacitor depends on what?​
bonufazy [111]

Answer:

The capacitance of a capacitor depends on the charge and voltage of a system. It is also dependent, if present, on the dielectric as well.

General Formulas and Concepts:
<u>Gauss's Law</u>

Capacitance Formula: \displaystyle C = \frac{Q}{V}

  • <em>Q</em> denotes charge
  • <em>V</em> denotes voltage

Dielectric Capacitance Formula:  \displaystyle C = \kappa C_0

  • <em>C₀</em> denotes original capacitance
  • <em>κ</em> denotes the dialectic constant

Explanation:

A <u>capacitor</u> <em>stores</em> charge when run through an electrical current. The <u>capacitance</u> is <em>how much </em>charge a capacitor can hold.

We can define the relationship of capacitance by using the formula. Capacitance is <em>inversely proportional</em> to the potential energy, or <u>voltage</u>, of the system. Therefore, you will need to know what the <u>charge</u> Q of the system as well has voltage V in order to find the capacitance.

If there is a dielectric involved inside the capacitance, you also must incorporate the value of the <u>dielectric constant </u>into your capacitance. A dielectric is <em>directly proportional </em>to the capacitance; the bigger the dielectric constant, the bigger capacitance, as denoted in our equation.

How long a star lives and what it becomes at the end of its life depends primarly on what
liraira [26]
I believe the answer would be mass. Low mass stars and medium mass stars often become white dwarfs when they die while high mass stars explode in violent explosions called supernovas and usually leave behind a black hole or a neutron star.

Janet ran 30 meters in 4 seconds,what is her speed.
lubasha [3.4K]

Answer:

7.5 meters per second

Explanation:

30 / 4 = 7.5

7.5 * 1 = 7.5

7.5 * 2 = 15

7.5 * 3 = 22.5

7.5 * 4 = 30
