Sound waves will either be reflected (echo effect) or absorbed (dissipated) depending upon the material make-up of the barrier
Answer:
speed of light waves change when they travel in air to aquarium because want's the light hits the water you see bunches of color along with bigger looking objects
Explanation:
These weights are minus the transmission which can push the car engine weight to around 600 pounds. While most formula ones cars are extremely fast the engines used are lightweight and weigh 100 kg or 210 pounds.
Answer:
Same reading.
Explanation:
Assume that after the string breaks the ball falls through the liquid with constant speed. If the mass of the bucket and the liquid is 1.20 kg, and the mass of the ball is 0.150 kg,
A.) Before the string break, the total weight = weight of the can + weight of the water.
According to Archimedes' Principle which state that: “A body immersed in a liquid loses weight by an amount equal to the weight of the liquid displaced.” Archimedes principle also states that: “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it
B.) After the string break.
The scale will have the same reading as before the string break.
Frequency = rate of sploosh = 2 per second = 2 Hz.
Period = ( 1/frequency ) = 1/2 second
Speed = (wavelength) x (frequency) = (0.15m) x ( 2/sec) = 0.075 m/s .
