Answer:There's an increase in it potential energy
Explanation:there is an increase in it potential energy
Answer:
option 3
Explanation:
work is said to be the ability to move an object from it initial position. therefore, holding a tray is not a work
To solve this problem we will use the concepts related to the flow rate, which describes the volumetric amount of a fluid that travels a point in a given time. Mathematically it can be expressed as
Q = AV
Where
A= Area
V = Volume
Our values are given as
V = 2.5m/s
Replacing we have to
At this point we know that 1 m ^ 3 of water is equivalent to 1000Kg (Its value in density at normal conditions)
