Answer: Temperature is the average kinetic energy of the molecules (how hot or cold something feels). Heat energy is the energy created y the motion of the molecules in an object. Heat flows from hot body to cold body. Temperature rises when heated and falls down when an object is cooled down.
There are three main scales commonly used in the world today to measure temperature: the Fahrenheit (°F) scale, the Celsius (°C) scale, and the Kelvin (K) scale. Each of these scales uses a different set of divisions based on different reference points, as described in detail below.
Explanation:
Answer:
infinity
Explanation:
Given that
Resistance = R
Resistivity = ρ
Length = L
Diameter = d
The resistance of wire R given as
A=Area
Now by putting the value of A
When d tends to infinity then d² will also tends to infinity.
So when d tends to zero then the resistance tends to infinity.
Therefore answer is ---
infinity
Answer: 25 kg
Identify the given information.
f = 250 N
a = 10 m/s^2
Choose which formula you should use. In this case, you are finding the mass.
The formula for force is f = ma, so, using this, it is easy to find the mass.
f = ma Divide by a for both sides
m = f/a Formula for mass!
The formula for mass is m = f/a, where f is force and a is acceleration.
Substitute.
m = (250 N)/(10 m/s^2)
m = 25 kg
<span>The answer is C. A scale would include a series of eight notes, where the first and seventh notes have the same letter.
Just took the test. Got 100%
