2y²-18xy+2x²
what type of expression is this
Answer:
There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases.
Explanation:
At high pressures, the two factors that cause deviation during ideal gas law calculation are the size of molecular and intermolecular force.
The high pressure causes the molecules to approach each other at a very close distance. In that case, if the intermolecular force of attraction is high, the molecules may undergo a state transition, which will result in a completely different outcome as predicted by Ideal gas law.
If the size of the molecule is more, that is for heavy gases like refrigerants, the ideal gas law deviates due to the fact that, with increase in pressure, the volume of gas can no longer be considered as negligible.

It’s because of refraction! the light bends at an angle and makes the straw look bent/broken. it’s just the way the light hits the glass that makes the straw look like that
The speed with which runner is running is 7.07m/s
<u>Explanation:</u>
Given:
Mass, m = 60kg
Kinetic energy, KE = 1500J
Velocity, v = ?
We know,
Kinetic energy = 
On substituting the value we get,
Therefore, the speed with which runner is running is 7.07m/s
