Answer:
6.78571 m/s
55.13387 Joules
Explanation:
= Velocity of squid = 2.5 m/s
= Velocity of water
= Mass of water = 1.75 kg
Mass of squid
Momentum of squid
As the momentum of the system is conserved
The speed of the water is 6.78571 m/s
Kinetic energy the squid creates is given by
Kinetic energy of the squid + Kinetic energy of water
Kinetic energy the squid creates by this maneuver is 55.13387 Joules
Answer:
The intensity in 10-3 W/m2 at 39.3 m is
Explanation:
Given Data:
frequency=1,054 Hz
intensity=6.429 mW/m^2
distance=7.945 m.
Required:
intensity in 10^-3 W/m^2 at 39.3 m=?
Solution:
Intensity at distance r from point source which is emitting sound waves of power P is given by the following formula:
Intensity=I=
Where:
P is the power
r is the distance
The intensity in 10^-3 W/m2 at 39.3 m is

Answer
-Directly; outside air pressure
Vapor pressure is directly related to the temperature of the liquid. user: in an open system, the vapor pressure is equal to the outside air pressure.
Explanation;
-As the temperature of a system increases, the average kinetic energy of the molecules increases in both the liquid and gas phases.
-A higher average kinetic energy facilitates the escape of molecules from the liquid phase into the gas phase. At the same time, the rate of return of gas phase molecules to the liquid also increases. A new equilibrium point is reached at a higher gaseous vapor pressure. The increase in vapor pressure with temperature is exponential.
