if the velocity of a vehicle starting from rest reaches 5m/2s in 2seconds, is the velocity of the vehicle uniform ?explain.​
Vanyuwa [196]

Explanation:

Avg speed × total times = total distance

20×25=500

Since acceleration in the 1st interval is same as deceleration in the 3rd interval and deceleration is from the same velocity achieved after acceleration, t

Describe the procedure of water reaching the leaves from the roots of a plant
Lisa [10]
The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
