The same as the voltage in all bulbs. The series circuit is a pattern of the circuits in which the loads will have the same amount of power and consumed voltage. If one load goes out, the others will turn off also. This is because they have connected wires and pattern.

The sum of potential and kinetic energies in the particles of a substance is called

olganol [36]

Internal energy.

Explanation:

In any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called Brownian motion). As a result, the particles have some kinetic energy (which is proportional to the temperature of the substance). Moreover, the particles interact with each other due to the presence of electrostatic intermolecular forces, and as a result, the particles also have some potential energy.

The sum of the kinetic energies and potential energies of the particles in a substance is called internal energy.

A 45.0 kg student runs at a constant velocity up the incline 6 metres high. If the power output of the student is 1.50 x 103 W,

serg [7]

Answer:

The time taken is 1.76 s.

Explanation:

mass of student, m = 45 kg

height, h = 6 m

power, P = 1500 W

Power is defined as the rate of doing work.

Work done in moving height is

W = m g h

Let the time is t.

P = m g h / t

1500 = 45 x 9.8 x 6 / t

t = 1.76 s

If 317. 7 coulombs was used in an electrolytic cell, how many grams of zn would we expect to be plated from a zn2 solution onto

viva [34]

Answer: The amount of Zn plated from a solution is 1.07× $10^{-1}$ grams.

Explanation: In this question, it is given that of 317.7 coulombs was used in an electrolytic cell, i.e,

The amount of charge = 317.7 coulombs

The amount of charge of 1 mole of electrons = 96485.3 coulombs ( FARADAY’S CONSTANT )

Now, the number of electrons = amount of charge given / charge of 1 mole of electrons

The number of electrons = $\frac{317.7}{96485.3}$ = $3.29$ × $10^{-3}$

According to reaction occurring, 2 moles of electrons are required to convert 1 mole of to Zn which is plated on the electron, so the moles of Zn plated will be half the moles of electrons, i.e.,

$\frac{3.29*10^{-3} }{2}$ = 1.645× $10^{-3}$

Now, we know that the molar mass of zinc is 65.38gm/mole,

Number of moles = mass in grams / molar mass

Mass in grams = number of moles × molar mass

Mass in grams = (1.645× $10^{-3}$ ) × 65.38 = 0.1075 gm.

Conclusion: It concludes that the amount of Zn plated from a 1.07× $10^{-1}$ solution is gm.
