Answer:
Explanation:
Intake heat, QH = 100 J
output heat, Qc = 20 J
Work, W = 80 J
TH = 100°C = 373 K
Tc = 10°C = 283 K
TH/ Tc = 373 / 283 = 1.318
QH/Qc = 100 / 20 = 5
for a heat engine, those ratios should be same. so temperature is not correct.
Hello!
Static electricity occurs due to an imbalance in positively and negatively charged atoms. An example of this is when you take your clothes out of the dryer, and feel a slight sting when touching them. Another example of static electricity is lightning.
Current electricity occurs when there is a constant flow of electrons, such as in plug-operated machinery or anything operated using a battery. :)
speed, volume, mass, temperature and power
The realtionship between force in Newtons, mass in kilograms and acceleration in metres per second squared is described by Newton's second law of motion which is Force = mass times acceleration, or F=ma. You need to know the mass, so rearrange the formula to solve for m, giving m=F/a
In your example, the mass is therefore 8480 divided by 32, which is equal to 265kg.
It looks like Doppler effect. Sound waves passing through a big way until they get to your ears. We got the highest frequency when we receive it, while it goes it remains the same and when it goes down we receive lower frequency.
