In order to solve this problem, it is necessary to apply the concepts related to the Pressure according to the Force and the Area as well as to the pressure depending on the density, gravity and height.
In the first instance we know that the pressure can be defined as
Where
F= Force
A = Mass
In the second instance the pressure can also be defined as
Where,
Density of Fluid at this case Water
g = Gravitational Acceleration
h = Height
If we develop the problem to find the pressure then,
Through the second equation we can find the depth to which it can be submerged,
Re-arrange to find h
Answer:
YES
Explanation:
An echo may be defined as a sound which is repeated because of the sound waves that are produced are reflected back after striking a surface. Sound waves can smoothly bounce off the hard objects in the same manner as a rubber ball bounces back the ground.
When a sound wave strikes a hard surface, the sound waves gets reflected back and bounces back to the observer and produces an echo. If the sound waves strikes a soft surface it absorbs the sound.
Although the direction of a sound changes but the echo sounds in the same way as the original sound.
The speed of sound will increase because the rate at which the air particles move will increase. As rarefaction and compressions are formed at a faster rate, the frequency increases, thereby increasing the speed.
Answer:
Explanation:
Given that,
The mass of a golf ball, m = 45.9 g = 0.0459 kg
Speed of the tee, v = 63 m/s
We need to find the corresponding wavelength. The relation between wavelength and speed is given by :
So, the corresponding wavelength is 
.
