Answer:

To determine the volume of a given beaker/calorimeter by measuring its internal diameter and depth with vernier calipers. A vernier caliper is a measuring instrument with two scales: a main scale and a vernier scale that slides over the main scale.

Calculate the net force on particle q1.
antoniya [11.8K]

By applying Coulomb's law between the charges, the net force on the charged particle q₁ due to particle q₂ and q₃ is -9.86 N.

<h3>Distance between q₂ and q₃</h3>

The distance between the second charge and the third charge is given as;

r = 0.3 m

<h3>Force on q₂ due to q₃</h3>

F_{2} = \frac{kq_2q_3}{r^2} \\\\F_{2}= \frac{(8.99\times10^9) (7.7 \times 10^{-6})(5.9\times 10^{-6}) }{0.3^2} \\\\F_2 = 4.54\ N

<h3>Net force on particle q₁</h3>

The net force on particle q₁ is determined by summing the individual forces together;

F(net) = F₁ + F₂

F(net) = -14.4 + 4.54

F(net) = -9.86 N

Thus, by applying Coulomb's law between the charges, the net force on the charged particle q₁ due to particle q₂ and q₃ is -9.86 N.

5) A parallel series electric blasting circuit consists of 6 branches of 8 caps each. Cap legwire length is 28 ft. The cap circu
andrezito [222]

Answer:

Minimum DC current = 9 Ampere

Voltage = 74.862 V

Explanation:

Here in this questions three resistors are used in series

Resistance of cap circuit

R_1 =\frac{ 8* 2.3}{6} \\R_1 = 3.067

Here 2.3 is the resistance per cap

Resistance of bus wire

R_2 = \frac{50 * 4.02 }{1000} \\R_2 = 0.201

Where 4.02 is the resistance per 1000 feet of bus wire of gauge 16

Resistance of firing line

R_3 = \frac{(2*1000)* 2.525}{1000} \\R_3 = 5.05

where 2.525 is the resistance per 1000 feet of bus wire of gauge 14

Total resistance is equal to

R = R_1 + R_2 + R_3\\R = 3.067 + 0.201 + 5.05 \\R = 8.318

Current in firing line is equal to

1.5 * 6\\= 9

Voltage is equal to product of resistance and current

= 9 * 8.318\\= 74.862
