Answer:
80.386 degrees
Explanation:
We use the cosine equation here (which is the adjacent side of the unknown angle divided by the hypotenuse
The adjacent side = 699ft
The hypotenuse = 1034ft
using cos∅ = Adjacent/hypotenuse
where ∅ is the unknown angle
cos ∅ = 699/1034 = 0.167
∅ = arccos 0.167 = 80.368°
As easy as one can imagine
Answer:
The bigger the object, the more heat that can be transferred. Ex: An iceberg would transmit more heat than a kettle
Explanation:
Answer:
5.63 gram
Explanation:
As per the equation
Q = Lm
where Q is the amount of heat needed to convert water in to vapour
and L is the latent heat f vaporization.
m is the mass converted, hence putting all the values.
m =Q/L
= 12725400/ 2260000
= 5.63 gram
Answer:
a. one-fourth its original value.
Explanation:
Sound is threated as a spherical wave. The intensity of the sound is inversely proportional to the area of the wavefront (). Therefore, it is inversely proportional to the square of the distance (r) to the sound source. So, if you double your distance, the intensity of the sound reduces to one-fourth its original value.
Think it’s A. Cause a blue supergiant temperature will be around 20,000k
