Answer:
Hydraulic pressure exerted on glass slab, ρ=10 atm
Bulk modulus of glass, B=37×10^9 Nm^−2
Bulk modulus, B=P/(ΔV/V)
where,
ΔV/V= Fractional change in volume
ΔV/V=P/B
=10×1.013×10^5 /(37×10 ^9)
=2.73×10^-5
Therefore, the fractional change in the volume of the glass slab is 2.73×10^-5
Hope it helps
Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that electric field intensity due to some given charge distribution is given as

now electric flux through a spherical surface of radius r is given as


now by Guass law we know that


now volume charge density is given as


Part b)
Total charge inside the radius R is given as

Answer:
<h3>The answer is 11 mL</h3>
Explanation:
To find the volume of the object we use the formula
volume of object = final volume of water - initial volume of water
From the question
final volume of water = 86 mL
initial volume of water = 75 mL
So we have
volume of object = 86 - 75
We have the final answer as
<h3>11 mL</h3>

Answer:
Alice Distance = 100 meters
Peter's Distance = 3 km
Alice Displacement and Peter's displacement are both 100 meters upwards.
Explanation:
To solve this question, we have to first define distance and displacement.
Distance is simply the measurement of the sum of all paths travelled from one point to another while displacement is measurement of the shortest distance from initial point to final point.
Now, Alice and Peter are moving from the same point.
Alice distance travelled is 100 meters.
Also, her displacement will be 100 meters because it is the shortest distance to the summit of the cliff.
Now, for Peter, he decides to take a longer route which is 3 km in distance.
However, the shortest path which is the displacement is still 100 meters.
Thus, Peter's displacement is 100 meters.
Answer:
Explanation:
Theoretical efficiency = T₁ - T₂ / T₁ where T₁ and T₂ is absolute temperature of hot and cold end of the heat engine.
= 600 / (273 + 700 )
= 600 / 973
= .6166
operating efficiency = 40% of .6166
= .4 x .6166
= .2466 = 24.66 %
efficiency = work output / heat input
= 5000 / heat input = .2466
heat input = 5000 / .2466
= 20275.75 J .
HEAT EXTRACED = 20275.75 J.
