The annoying sound from a mosquito is produced when it beats its wings at the average rate of 600 wingbeats per second. What is
podryga [215]
Frequency is given by the formula cycles÷seconds

So if the mosquito can complete 600 cycles in one second, our formula will be

f=600÷1
f=600!

The frequency is 600 Hz

How much heat is needed to change the temperature of 3 grams of gold (c = 0.129 ) from 21°C to 363°C? The answer is expressed to
Temka [501]

Q= mcΔT

Where Q is heat or energy

M is mass, c is heat capacitance and t is temperature

You have to convert Celsius into kelvin in order to use this formula I believe

Celsius + 273 = Kelvin

21 + 273 = 294K

363 + 273 = 636K

Now...

Q= (0.003)(0.129)(636-294)

Q= 0.132 J if you are using kilograms, in terms of grams which seems more appropriate the answer would be 132J of energy.
