I believe the answer is High thermal energy.
If a substance has a low specific heat, it means it will heat or cool quickly than a high heat compound.
High value means that it takes more energy to raise or lower its temperature, while a low value means that it does not take very much energy to heat or cool it. Adding heat to a low specific heat compound will increase its temperature much more quickly than adding heat to a high specific heat compound.
Answer:
0.28 ft
Explanation:
We are given that
Strength=m=
Distance between source and sink=15 ft
Distance between the sink of the source and origin=
ft
Uniform velocity, U=12 ft/s
We have to find the length of the oval.
Formula to find the half length of the body
Where a=Distance between sink of source and origin
U=Uniform velocity
m=Strength
l=Half length
Using the formula
Length of oval=
There are various reasons why a measurement tool cannot be accurate. One of them is thermal contraction and expansion varies according to seasons.
<h3>What are Accuracy and Precision?</h3>
There are two ways to assess observational error: accuracy and precision. Precision measures how closely two measurements are to one another, whereas accuracy measures how close a group of measurements is to its actual value. In other words, precision is a measure of statistical variability and a description of random errors.
We can say that a tool can be precise, but it cannot be accurate. There are various reasons behind that, some of them are :
- It may not be calibrated properly. If there are no reliable standards to use for calibration, this may occur.
- Perhaps it strayed. This is why electronic scales include a tare function—they are terrible in this area.
- Perhaps the measurements are not linear. Our calipers might have been quite precise at the 2-inch standard, where they were calibrated, but inaccurate at other dimensions.
- Temperature is one environmental component that the instrument might be sensitive to. These effects might be compensated for, but the compensation might not be ideal. This issue affects both dissolved solids meters and picometers.
These are some of the reasons due to which measurement tool cannot be accurate.

Answer:you can just look this up yknow?
Explanation:
Explanation:
a. Average speed = distance / time
= 100 m / 70 s
= 1.43 m/s
b. Average displacement = displacement / time
= 0 m / 70 s
= 0 m/s
Distance is the length of the path traveled. Displacement is the difference between the final position and initial position.
