Answer:
E=h.f
=5.2×1014×6.63×10^-34
E=3.496×10^-30 J
( 8.10) x 10^4 J = ½(1010kg)V²
<span>......................= 505V² </span>
<span>( 8.10) x 10^4 J =[(.0505) x 10^4] V² ........<==10^4 cancels </span>
<span>8.10 = .0505 V² </span>
<span>.........______ </span>
<span>V = ²√ 160.4 </span>
<span>V= 12.6 m/s </span>
<span>(that's 12.6m/sec(1km/1000m)(3600secs/1hr) = 45.36kph) </span>
<span> my diagram is wrong, it is just an ordinary car, </span>
Microsecond is greater
A microsecond is 0.000 001 second and one thousand times longer than 1 nanosecond, which is 0.000 000 001 second.
The total amount of energy transferred as heat is equal to 288 Joules.
<u>Given the following data:</u>
- Internal energy = 123 Joules
To calculate the total amount of energy transferred as heat, we would apply the first law of thermodynamics.
<h3>The first law of thermodynamics.</h3>
Mathematically, the first law of thermodynamics is given by the formula:

<u>Where;</u>
is the change in internal energy.
- Q is the quantity of heat transferred.
Substituting the given parameters into the formula, we have;

Q = 288 Joules.

Answer: 3.33 m/s
Explanation:
Assuming the questions is to convert 12 km/h to meter per second (m/s), let's begin:
In order to make the conversion, we have to know the following:

And:

Keeping this in mind, we can make the conversion:

Then:
