Answer:
Everything that has mass has gravity. The greater the amount of mass, the greater the gravity. And the closer objects are to each other, the stronger their gravitational pull is. The reason we have weight is because of the gravitational pull on our bodies (our mass) by the Earth.

Voltage = Current * Resistance
In the given question, there are numerous information's that are already given.
Current = 6.2 A
Resistance = 18 ohms
Then
Voltage = 6.2 * 18 Volts
= 111.6 Volt
So, the voltage in the circuit will be 111.6 volts. I hope it helps you.
If you are doing a USA TEST Prep:
D) 111.6 V

Translational motion is the motion by which a body shifts from one point in space to another. One example of translational motion is the the motion of a bullet fired from a gun. An object has a rectilinear motion when it moves along a straight line. Hope this helps! :)
Answer:
Translational motion is the motion of body where body moves in the linear path. It is the motion in which all points of a moving body move uniformly in the same line or direction.

Answer:
The average velocity is 50 km/h south
Explanation:
The average velocity of an object is its total displacement divided by
the total time taken.
That means it is the rate at which an object changes its position from
one place to another.
Average velocity is a vector quantity.
The SI unit is meters per second.
A bicycle that starts 100 km south and is 120 km south of town after
0.4 hour.
The displacement = 120 - 100 = 20 km south
The time = 0.4 hour
The average velocity = , where D is the displacement
and t is the time
The average velocity of the bicycle = km/h
The average velocity is 50 km/h south
If you want it in meter per second, change the kilometer to meter
and change the hour to seconds
1 km = 1000 m
1 hour = 60 × 60 = 3600 seconds
The average velocity of the bicycle = m/s south
