<span>Audible beats are formed by the interferences of two waves in which are from the slightly different frequencies which is letter a. It is because having two waves that consist of slightly different frequency causes or produce the audible beats to be formed in which they are beats that causes sound to be either loud or soft.</span>
Using kinematic equation s=ut + 1/2 at^2(u = initial velocity=0, s=120m, t= 6.32s), 120 = 0(t) + 1/2 a(6.32)^2. a = 120x2/(6.32)^2 = 6m/s^2.
Answer:
changes
Explanation:
According to Michael Faraday, voltage is induced on a metallic conductor when the magnetic field changes. The principle is known as the principle of electromagnetic induction. The voltage induced on the metallic conductor is referred to as induced emf.
The magnitude if induced emf depends on the rate of change of the magnetic flux.
Answer:
775 grams of ice
Explanation:
Heat loss by patient = heat gained by ice
Heat loss by patient = mass×specific heat capacity×(initial temperature - final temperature) = 62×4200×(40-39) = 260,400J
Heat gained by ice = mass × specific latent heat of fusion of ice = m×336000 = 336000m J
336000m = 260,400
m = 260400/336000 = 0.775kg = 0.775×1000 grams = 775 grams of ice
