Explanation:
mass of student(M1)=55
mass of book(M2)=?
distance(d)=0.435m
gravitational constant (G)=6.67×10^-11
force(F)=2.68×10^-8
Now,
F=GM1M2/d^2.
then do the numericals .It's taking long time so I escaped Sorry
The amount of metal in a closed cylindrical can that is 10 cm high and 4 cm in diameter if the metal on the top and the bottom is 0.1 cm thick and the metal on the sides is 0.05 cm thick is 8.8 cm.
The formula for calculating the volume of a cylinder is given below.
V = πr^2 h
Get the differential of the volume as shown:
dV = V/ h dh + V / r dr
V/ h = πr^2
V/ h = 2 πr h
Now, the differential becomes
dV = πr^2dh + 2πrh dr
Given the following parameters i.e. diameter and height
dh = 0.1 + 0.1 = 0.2 cm
dr = 0.05 cm
h = 10 cm
d = 4 cm
r = 2cm
Substituting the values in the above equation, we get
dV = 3.14(2)^2(0.2) + 2(3.14)(2)(10)(0.05)
dV = 2.512 + 6.28
dV = 8.792 cm
dV = 8.8 cm

Answer:
A wet body has a relatively high concentration of water. When this is transferred to a towel, the large surface area of the towel fabric distributes the water molecules over a much greater surface area, so the relative concentration is lower.
Answer:
The capacitance is 1.75 nF
Explanation:
From the question we are given that
The inner radius is
The outer radius is 000.1
Length of the capacitor is L = 1m
The dielectric constant is Di = 2
The dielectric constant is Di2 = 4
Generally the capacitance of a capacitor can be mathematically represented as
1.75nF
