Quantum entanglement<span> is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the </span>quantum<span> state of each particle cannot be described independently — instead, a </span>quantum<span> state must be described for the system as a whole.</span>
Explanation:
The wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.

Answer:
0.88
Explanation:
velocity (v) = 22 m/s
radius (r) = 56 m
acceleration due to gravity (g) = 9.8 m/s^{2}
What minimum coefficient of static friction between the tires and road is necessary for the car to round the curve without slipping?
for the car to successfully go round the curve, the frictional force must be equal to or greater than the normal force, therefore
Normal force = frictional force
ma = μmg
where
- μ = coefficient of friction
- g = acceleration due to gravity
- a = = = 8.6
- putting in all required values the equation now becomes
8.6m = μm x 9.8
8.6 = 9.8 x μ
μ = 8.6/9.8 = 0.88
