Answer:

volt, unit of electrical potential, potential difference and electromotive force in the metre–kilogram–second system (SI); it is equal to the difference in potential between two points in a conductor carrying one ampere current when the power dissipated between the points is one watt.

The volts (symbol V) measure the different potential energy that exists between one point and the other. The volts are thus named in honor of Alessandro Volta, the inventor of the battery.

Batteries move anions (negatively charged things) and cations (positively charged things) to opposite terminals, creating a voltage. Voltage is better expressed as electric potential.

Voltage is the electrical force that causes free electrons to move from one atom to another. Just as water needs some pressure to force it through a pipe, electrical current needs some force to make it flow. "Volts" is the measure of "electrical pressure" that causes current flow.

A motorcyclist drove 7 km at 57km/h and then another 7 km at 81 km/h. What was the average speed?

alex41 [277]

<u>Answer:</u>

<em>The average speed of the car is 66.9 km/h</em>

<u>Explanation:</u>

Here distance covered with the speed <em>57 km/h=7 km </em>

distance covered with the speed of <em>81 km/h=7 km</em>

<em>Average speed is equal to the ratio of total distance to the total time. </em>

<em>total distance= 7 + 7= 14 km </em>

<em> $time= \frac{distance}{speed}$ </em>

<em>time taken to cover the first 7 km= 7/57 h </em>

<em>time taken to cover the second part of the journey = 7/81 h </em>

<em>average speed = $14/(7/57+7/81)=(14 \times 57 \times 81)/945=66.9 km/h$ </em>

<u><em>Shortcut: </em></u>

<em>When equal distances are covered with different speeds average speed=2 ab/(a+b) where a and b are the variable speeds in the phases. </em>

The strength of the force of gravity depends on a. the masses of the objects and their speeds. b. the masses of the objects and

Lostsunrise [7]

Gravitational force = Gxm1xm2 /r^2 This equation depends only upon object's masses and distance between them. So option b is correct
