The gravitational force of attraction between two students sitting at their desks in physics class is 2.59 × 10−8 N. If one stud

ent has a mass of 31.9 kg and the other has a mass of 30.0kg, how far apart are the students sitting? The universal gravitational constant is 6.673 × 10−11 N · m2/kg^2.

Answer:1.57x10^(-8)m

Explanation:

Force(f)=2.59 x 10^(-8)N

Mass1(M1)=31.9kg

Mass2(M2)=30kg

Gravitational constant(G)=6.673x10^(-11)

Distance apart(d)=?

F=(GxM1xM2)/d^2

2.59x10^(-8)=(6.673x10^(-11)x31.9x30)/d^2

2.59x10^(-8)=(6.39x10^(-8))/d^2

d^2=(6.39x10^(-8))/(2.59x10^(-8))

d^2=2.47x10^(-16)

d=√(2.47x10^(-16))

d=1.57x10^(-8)m

<h2>The distance between students is 2.46 m</h2>

Explanation:

The force of attraction due to Newton's gravitation law is

F = \frac{Gm_1m_2}{r^2}

Here G is the gravitational constant

m₁ is the mass of one student

m₂ is the mass of second student .

and r is the distance between them

Thus r = \sqrt{\frac{Gm_1m_2}{F} }

If we substitute the values in the above equation

r = \sqrt{\frac{6.673x10^-^1^1x31.9x30.0}{2.59x10^-^8} }

= 2.46 m

What would happen when two or more capacitors are connected in parallel across a potential difference?
Varvara68 [4.7K]

Answer:

The Current Iₜ = I₁ + I₂ + I₃

Charge Qₜ = Q₁ + Q₂ + Q₃

Potential difference Vₜ = V₁ = V₂ = V₃

The total capacitance Cₜ = C₁ + C₂ + C₃

Explanation:

According to the attached image;

For parallel arrangements of capacitors, the current flowing through each of the capacitors sums up to the total current flowing through the circuit;

Iₜ = I₁ + I₂ + I₃

Also the charge storage by each capacitor sums up to give the total charge stored;

Qₜ = Q₁ + Q₂ + Q₃

The potential difference across each of the capacitors are the same and equal to the total voltage across the circuit;

Vₜ = V₁ = V₂ = V₃

The total capacitance equals the sum of the capacitances of each of the capacitors;

Cₜ = C₁ + C₂ + C₃
