Answers:
The transportation industry is no stranger to the manipulation of everyday physics. Cars and trains utilize the wheel, which provides a smooth, steady motion.
The ears hear sounds which occur through the movement of air molecules, and the chemistry that drives all of biology depends on the physics of energy and molecules. Every day, for example, plants absorb sunlight, water, and carbon dioxide, creating glucose and releasing oxygen as a byproduct.

Movement of minerals in plant
Explanation:
In Biology, Active transport means Movement of molecules from lower concentration to Higher concentration through a membranous substance.
It is clearly shown in transportation of minerals from root hairs to root cells.
From root hairs( Lower concentration) minerals are transported to other parts of plant ( Higher concentration, Active transport takes place.
It is clearly evident that in this natural process active transport of minerals takes place effectively through root hairs to various parts of plant.
Answer:
less energy is needed to heat the house
the roof is a better insulator
Answer:
u = 13.67 m/s
Explanation:
given,
window height = 2 m
window is 7.5 m off the ground on its path up
total distance from the ground to pass the window = 2 + 7.5 = 9.5 m
time taken to go past the window = 1.30 s
using equation of motion



u = 13.67 m/s
hence, the initial velocity of the ball is equal to 13.67 m/s
