Answer:
Water is essential to life because of four important properties: cohesion and adhesion, water's high specific heat, water's ability to expand when frozen, and its ability to dissolve a wide variety of substances.
Answer:
they are given below
The sum or resultant of all external forces acting on the body must be equal to zero.
The sum or resultant of all external torques from external forces acting on the object must be zero.
Answer:
Mirage is an optical illusion due to the refraction of light as it travels through different layers of air at different temperature.
Explanation:
On a clear hot afternoon, the sun heats up the ground, and the ground heats up the air immediately above it. The result is that the air directly above the ground is hotter than the air above it, leaving the air layers with different refractive indies. Since refractive index decreases with increase in temperature, the air immediately above the ground bends the light that travels through it from the sky, directly into our eyes. The image seen is perceived to be reflected from the ground, but in an actual sense is a direct image of the sky, giving one the impression of seeing a pool of water on the ground.
- Initial velocity=20m/s
- Final velocity=0m/s(As the car stops)
- Acceleration=-8m/s^2
- Distance=s=26m
We need to verify the thrid equation of kinematics here
The squirrel has a good luck ,Car gets stopped just 1m away from the squirrel .
