Use your observations of the circuit construction simulation experiment and your course notes to answer the following questions.

Which statement is true? When two resistors are connected in series, there is less total current in the circuit than if the two resistors were connected in parallel. When two resistors are connected in parallel, there is less total current in the circuit than if the two resistors were connected in series. The total current is the same regardless of if the two resistors are connected in series or in parallel.

Answer:

When two resistors are connected in series, there is less total current in the circuit than if the two resistors were connected in parallel.

Explanation:

When two or more resistors are connected in series then total resistance is given as

R = R_1 + R_2

while if two or more resistors are connected in parallel then total resistance is given as

\frac{1}{R} = \frac{1}{R_1} + \frac{1}{R_2}

so here we can say that net resistance would be less in the circuit if resistors are connected in parallel

so here we can say that

When two resistors are connected in series, there is less total current in the circuit than if the two resistors were connected in parallel.

<span>I didn't do the circuit construction simulation experiment, and
I don't have any course notes.  Both of those were YOUR job. 

But I'm still going to take your points.  I'll try to answer the question
based on what I know, and you'll just have to decide whether you
trust me, even though I never had any contact with your class or
anything that happened there.

I believe that when two resistors are connected in series,
there is less total current in the circuit than if the two resistors
were connected in parallel.  That's the first choice.</span>

The electron's velocity at that instant is purely horizontal with a magnitude of 2 \times 10^5 ~\text{m/s}2×10 ​5 ​​ m/s then ho
Lesechka [4]

Complete question:

At a particular instant, an electron is located at point (P) in a region of space with a uniform magnetic field that is directed vertically and has a magnitude of 3.47 mT. The electron's velocity at that instant is purely horizontal with a magnitude of 2×10​⁵​​ m/s then how long will it take for the particle to pass through point (P) again? Give your answer in nanoseconds.

[<em>Assume that this experiment takes place in deep space so that the effect of gravity is negligible.</em>]

Answer:

The time it will take the particle to pass through point (P) again is 1.639 ns.

Explanation:

F = qvB

Also;

F = \frac{MV}{t}

solving this two equations together;

\frac{MV}{t} = qVB\\\\t = \frac{MV}{qVB} = \frac{M}{qB}

where;

m is the mass of electron = 9.11 x 10⁻³¹ kg

q is the charge of electron = 1.602 x 10⁻¹⁹ C

B is the strength of the magnetic field = 3.47 x 10⁻³ T

substitute these values and solve for t

t = \frac{M}{qB} = \frac{9.11 *10^{-31}}{1.602*10^{-19}*3.47*10^{-3}} = 1.639 *10^{-9}  \ s \ = 1.639 \ ns

Therefore, the time it will take the particle to pass through point (P) again is 1.639 ns.

The mass of an object is 275.32g and its density is 7.562g/cm 3 . Calculate its volume by keeping significant figures in view.
Genrish500 [490]

Answer:

36.408cm3

Explanation:

Since we acknowledge that density is d= m/v, once we switch it up to maintain v as the number to be found it will change to v=m/d. Therefore, 275.32/7.562 is 36.408 and the unit is cm cube!

Hope that helped!!

Describe the general relationship between the weight of adult men and the average number of Calories needed daily to maintain a
Alexeev081 [22]

Answer:

The average number of calories needed daily represents the average quantity of calories eliminated by human body due to metabolism and must be compensated by eating and drinking.

The amount of calories contained in the food we eat every day must represent the amount of calories eliminated by the body in that time to have a steady weight.

Explanation:

The average number of calories needed daily represents the average quantity of calories eliminated by human body due to metabolism and must be compensated by eating and drinking. If total quantity of calories in the food we consume every day is higher that the average number of calories needed daily, then weight increases by fat accumulation.

A Carnot engine's operating temperatures are 240 ∘C and 20 ∘C. The engine's power output is 910 W . Part A Calculate the rate of
scoray [572]

Answer:1200

Explanation:

Given data

Upper Temprature\left ( T_H\right )=240^{\circ}\approx 513

Lower Temprature \left ( T_L\right )=20^{\circ}\approx 293

Engine power ouput\left ( W\right )=910 W

Efficiency of carnot cycle is given by

\eta =1-\frac{T_L}{T_H}

\eta =\frac{W_s}{Q_s}

1-\frac{293}{513}=\frac{910}{Q_s}

Q_s=2121.954 W

Q_r=1211.954 W

rounding off to two significant figures

Q_r=1200 W
