Answer:
V2 = 21.44cm^3
Explanation:
Given that: the initial volume of the bubble = 1.3 cm^3
Depth = h = 160m
Where P2 is the atmospheric pressure = Patm
P1 is the pressure at depth 'h'
Density of water = ρ = 10^3kg/m^3
Patm = 1.013×10^5 Pa.
Patm = 101300Pa
g = 9.81m/s^2
P1 = P2+ρgh
P1 = Patm +ρgh
P1 = 1.013×10^5+10^3×9.81×160.
P1 = 101300+1569600
P1 = 1670900 Pa
For an ideal gas law
PV =nRT
P1V1/P2V2 = 1
V2 = ( P1/P2)V1
V2 = (P1/Patm)V1
V2 = ( 1670900 /101300 Pa) × 1.3
V2 = 1670900/101300
V2 = 16.494×1.3
V2 = 21.44cm^3
Answer:Ek=673.109 kJ
Explanation:
Use equation for Kinetic energy: Ek=m*V²/2
m=650 kg (mass of roller coaster)
V=20.0Miles/s=20.0*1.609m/s=32.18m/s
Ek=m*V²/2
Ek=650kg*(32.18m/s)²
Ek=(650kg*1053.55m²/s²)/2
Ek=673 108.8 J
Ek=673.109 kJ
Answer: 5 m/s
Explanation:
Momentum = mv (mass*velocity)
60kg*m/s = (12kg)*(v)
v = (60kg*m/s)/(12kg)
v = 5 m/s
Unlike the IQ, your emotional intelligence (EQ) <u>may be improved over time by becoming more mindful</u>
<u />
Emotional intelligence is the understanding and usage of one's own emotions in a positive way to relieve their stress. It also helps for effective communication, to overcome challenges, to empathize and to defuse any bad situation.
Option A is the correct for IQ ( Intelligence quotient ). Option C is wrong because EQ can be built in any stage of your life. EQ is basically emotions. So option D is incorrect.
Therefore, Unlike the IQ, your emotional intelligence (EQ) may be improved over time by becoming more mindful

Do you remember the formula for potential energy ?
PE = (mass) (gravity) (height)
If the mass and the height are always the same, then the least PE comes from the least gravity. Surely you can find THAT in the table.
