A thin, metallic spherical shell of radius 0.187 m has a total charge of 6.53×10−6 C placed on it. A point charge of 5.15×10−6 C
MAVERICK [17]

Answer: a) 112.88 * 10^3 N/C; b) The electric field point outward from the center of the sphere.

Explanation: In order to solve this problem we have to use the gaussian law so we use a gaussian surface at r=0.965 m and the electric flux is equal to Q inside/εo

E* 4*π*r^2= Q inside/εo

E= k*Q inside/r^2= 9*10^9*(6.53+5.15)μC/(0.965)^2=122.88 * 10 ^3 N/C

(3) 8.3 N/kg. The gravitational field strength at a point is the force per unit mass exerted on a mass placed at that point. So at the point where the Hubble telescope is, it is (9.1 x 10^4)N/(1.1 x 10^4 kg) = 8.3 N/kg

 A balloon is 3m in diameter and is filled with 5 kg of N2. Find the specific volume of the gas in the balloon. Express it in bo
enyata [817]

Answer:

The the specific volume and weight are 79.16m³/k mol and 49 N.

Explanation:

Given that,

Diameter = 3 m

Mass of N₂ = 5 kg

We need to calculate the volume of balloon

Using formula of volume

V= \dfrac{4}{3}\pi r^3

V= \dfrac{4}{3}\pi \times{\dfrac{d}{2}}^3

V= \dfrac{4}{3}\pi \times(\dfrac{3}{2})^3

V=14.137\ m^3

We need to calculate the specific volume in the balloon

Specific\ volume=\dfrac{Volume}{mass}

Specific\ volume=\dfrac{14.137}{5}

Specific\ volume=2.8274\ m^3/kg

Now, Molar mass of N₂ gas is 0.028 kg/mol

Now, Specific volume of N₂ gas in the balloon is

Specific\ volume =0.028\times2.8274=0.0791672\ m^3/mol

Specific\ volume =79.16m^3/kmol

(b). We need to calculate the weight of the gas in the balloon

Weight of the balloon is dependent on the mass of the gas.

The weight of the gas is given by

W = mg

W = 5\times9.8

W = 49\ N

Hence, The the specific volume and weight are 79.16m³/k mol and 49 N.
