The answer is refraction. When a wave from one medium enters another medium, its direction changes due to the change of speed (phase velocity changes but frequency remains the same). The wave slows down when it enters a denser medium from the one it came from hence its path seems to bend.
Answer:
The pressure is
Explanation:
From the question we are told that
The gauge pressure at the mouth is
The radius of the column is
The speed of the liquid outside the body is
The area of the column is
The area inside the mouth
Generally according to continuity equation
=>
=>
=>
So
=>
=>
substituting values
Now the height of inside the mouth is
Now the height of the column is
Generally according to Bernoulli's equation
Now which is the density of water
is the gauge pressure of the atmosphere which is zero
So
Protons have a positive charge
Answer:
α = 11.05 rad/s^{2}
Explanation:
torque (T) = 2.1 N.m
moment of inertia (I) = 0.19 kg.m^{2}
angular acceleration (α) = ?
from torque = moment of inertia x angular acceleration
2.1 = 0.19 x α
α = 11.05 rad/s^{2}

Precipitation is a vital component of how water moves through Earth’s water cycle, connecting
the ocean, land and atmosphere. Water evaporates from the surface of the land and oceans,
rises and cools, condenses into rain or snow, and falls again to the surface as precipitation. The
water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it
flows back into the oceans. The cycling of water in and out of the atmosphere is a significant
aspect of the weather patterns on Earth. so that will be probs the best i can do
