The quantity of heat must be removed is 1600 cal or 1,6 kcal.
<h3>Explanation : </h3>
From the question we will know if the condition of ice is at the latent point. So, the heat level not affect the temperature, but it can change the object existence. So, for the formula we can use.
If :
- Q = heat of latent (cal or J )
- m = mass of the thing (g or kg)
- L = latent coefficient (cal/g or J/kg)
<h3>Steps : </h3>
If :
- m = mass of water = 20 g => its easier if we use kal/g°C
- L = latent coefficient = 80 cal/g
Q = ... ?
Answer :
So, the quantity of heat must be removed is 1600 cal or 1,6 kcal.

Answer:
f =63.64Hz
Explanation:
The equation of the transverse periodic wave
y = 0.005 sin(20.0x + 2ft)
From the equation we can deduce that
Amplitude A = 0.005
Wave number K = 20
Angular frequency w = 2πf
We are asked to find the frequency (f)
the formular for the wave number is given as K = 2π / lambda
Lambda = 2π/ K
Lamda is the wavelength
= 2 × 3.142 /20
= 0.3142m
The velocity of the wave is expressed as v = frequency × lamba (wavelength)
Frequency = velocity / wavelength
f = 20/ 0.3142
f = 63.65Hz
