lys-0071 [83]

Answer:

hope this helps!

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=

 Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.Displacement<span> is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

</span>To calculate displacement<span>, simply draw a vector from your starting point to your final position and solve for the length of this line. If your starting and ending position are the same, like your circular 5K route, then your </span>displacement<span> is 0. In physics, </span>displacement<span> is represented by Δs.
 
 For me to solve this I would need to know the time, but I can give you a handy displacement calculator I used that helped me.

Avi, a gymnast, weighs 40 kg. She is jumping on a trampoline that has a spring constant value of 176,400 . If she compresses the
viva [34]

<u>Answer</u>

9 m


<u>Explanation</u>

The energy stored in a spring is given by:

Energy = 1/2 k²e

Where e is the compression and k is the spring constant.

 Energy = 1/2 × 176,400 × 0.2²

              = 3,528 N

The same energy will then be converted to potential energy given by:

Energy = mgh

Where m is the mass, g is the gravity and h is the height above the ground.

Energy = mgh

3,528 = 40 × 9.8 × h

3,528 = 392h

h = 9 m
