Answer:
d)
Explanation:
the only one that makes sense
Answer:
P = 251, 3 W
Explanation:
The intensity is defined as the power emitted per unit area
I = P / A
Since sound is distributed in all directions spherical shape, the area of a sphere is
A = 4π r²
let's clear the power and replace
P = I A
P = I (4π r²)
let's calculate
P = 5.00 (4π 2²)
P = 251, 3 W
Answer:
Specific heat capacity is an intensive property and does not depend on sample size.
Explanation:
Advances in technology used to study and observe atoms lead to the discovery of electrons, protons, nuetrons, and the quarq
