Potential energy is the energy possessed by a body by virtue of its position or configuration . And energy is the capacity of doing work since power is work divided by time therefore change in potential energy divided by time is equal to the power of the object.
The rate at which the location of an object shifts in any direction. Speed is measured as the ratio of the distance travelled to the time it took to cover that distance. Speed is a scalar quantity since it just has a direction and no magnitude.
<h3>Explain about the speed?</h3>
It speaks of the motion of an object. Speed is calculated as distance travelled divided by time. Speed is measured in m/sec. Speed is a scalar quantity equal to the magnitude of the velocity vector. When a thing's speed is higher, it moves more quickly.
Speed refers to the rate at which a distance varies over time. It has a time-distance dimension. As a result, the SI unit of speed is created by combining the basic units of time and distance. As a result, the SI unit of speed is the meter per second (m/s)
The formula for an object's general speed is [Speed = Distance Time]. M/s is the SI unit of speed.

The magnitude of this vector:
18.4 mi-28.7 mj is 34.09m
Given:
vector is
18.4 mi-28.7 mj
Magnitude =
This magnitude of a vector formula summarizes the distinct vector measures along the x-axis, y-axis, and z-axis. It is represented by the symbol |v|. A vector's magnitude is either a positive number or zero, and it can never be negative. Let us finally understand the magnitude of a vector formula by considering a few solved cases.
A vector's magnitude is equal to its length. The magnitude of the vector an is indicated by the symbol a. For further information on vector magnitude, see the introduction to vectors.
This article deduces formulas for the magnitude of vectors in two and three dimensions in terms of their coordinates. The magnitude formula for a two-dimensional vector a=(a1,a2)

The correct answer is picture 1 because the grey arrow represents the real object size and the orange - yellowish arrow represents the image size. So since the image size is bigger than the object size. So this means picture 1 has a larger image.
