Which object has a varying speed? a bird flying at 10 m/s for 10 seconds a car slowing from 60 m/s to 0 m/s a car traveling the
dolphi86 [110]

Answer:

The car slowing from 60 m/s to 0 m/s

Explanation:

The bird flying at 10m/s for 10 seconds will have the same speed for those 10 seconds. So we can say it doesn't have a varying speed (During those 10 seconds, we don't have any information about what happens later).

The fish moving at 2m/s for 5 minutes will have the same speed for those 5 minutes. So we can say it doesn't have a varying speed (During those 5 minutes, we don't have any information about what happens later).

The car traveling the speed limit, we know that his speed is the speed limit. It doesn't change.

The car slowing from 60 m/s to 0 m/s needs to change his speed in order to go from 60 m/s to 0 m/s. The speed will decrease progressively until the car completely stops.

A lamp has a current of 2.17 A. In hours, how long does it take for 1 mole of electrons to pass through the lamp?
Gennadij [26K]

<u>Answer:</u> The amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.

<u>Explanation:</u>

We are given:

Moles of electron = 1 mole

According to mole concept:

1 mole of an atom contains 6.022\times 10^{23} number of particles.

We know that:

Charge on 1 electron = 1.6\times 10^{-19}C

Charge on 1 mole of electrons = 1.6\times 10^{-19}\times 6.022\times 10^{23}=9.6352\times 10^4C

To calculate the time required, we use the equation:

I=\frac{q}{t}

where,

I = current passed = 2.17 A

q = total charge = 9.6352\times 10^4C

t = time required = ?

Putting values in above equation, we get:

2.17A=\frac{9.6352\times 10^4C}{t}\\\\t=\frac{9.6352\times 10^4C}{2.17A}=44402s

Converting this into hours, we use the conversion factor:

1 hr = 3600 seconds

So, 44402s\times \frac{1hr}{3600s}=12.33hr

Hence, the amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.
