Answer:
a) 5.63 atm
Explanation:
We can use combined gas law
<em>The combined gas law</em> combines the three gas laws:
- Boyle's Law, (P₁V₁ =P₂V₂)
- Charles' Law (V₁/T₁ =V₂/T₂)
- Gay-Lussac's Law. (P₁/T₁ =P₂/T₂)
It states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant.
P₁V₁/T₁ =P₂V₂/T₂
where P = Pressure, T = Absolute temperature, V = Volume occupied
The volume of the system remains constant,
So, P₁/T₁ =P₂/T₂

Thermal energy - the internal kinetic energy in a substance caused by vibration of atoms and molecules. Thermal energy is also known as heat.
Radiant energy - is the electromagnetic energy that travels in waves. Radiant energy is kinetic energy that includes light, x-rays, microwaves, and radio waves.
Elastic energy - potential energy produced from stored or released elastic materials. This is stored mechanical energy energy resulting from being stretched or compressed.
Mechanical energy - the energy an object possesses due to movement. Mechanical energy is kinetic energy because it is the movement from one position to another.
Gravitational energy - the potential energy an object has because of position. This is produced from gravitational force acting upon an object.
Chemical energy - the potential energy stored in the bonds of molecules and compounds.
Nuclear energy - potential energy stored in the core (nucleus) of an atom.
Electrical energy - the kinetic energy produced from the movement of an electric charge.
Answer:
the answer is the explaination
Explanation:
Present beach erosion prevention methods include sand dunes, vegetation, seawalls, sandbags, and sand fences. Based on the research conducted, it is evident that new ways to prevent erosion must be obtained. Each way that is currently used has extensive negative effects on beaches and their natural tendencies.

Explanation:
Volume of the air bubble, V1=1.0cm3=1.0×10−6m3
Bubble rises to height, d=40m
Temperature at a depth of 40 m, T1=12oC=285K
Temperature at the surface of the lake, T2=35oC=308K
The pressure on the surface of the lake: P2=1atm=1×1.103×105Pa
The pressure at the depth of 40 m: P1=1atm+dρg
Where,
ρ is the density of water =103kg/m3
g is the acceleration due to gravity =9.8m/s2
∴P1=1.103×105+40×103×9.8=493300Pa
We have T1P1V1=T2P2V2
Where, V2 is the volume of the air bubble when it reaches the surface.
V2=
