Answer:
Hello! Your answer is, sound in the air is faster
Explanation:
The speed of sound through air is about 340 meters per second. It's faster through water and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second. So they're totally different scales.
Hope I helped! Ask me anything if you have any questions! Brainiest plz. Hope you make an 100% and have a nice day! -Amelia♥
We make use of a one-sample t-test for a population mean.

Option B
<h3> Sample mean and Sample standard deviation</h3>
A Sample Standard Deviation is the root-mean square of the data minus the sample mean,
The sample mean is is the mean of the randomly selected sample
Therefore, For a data or sample where we have no information on population standard deviation and here only one sample group is compared, we make use of a one-sample t-test for a population mean

Answer:
Speed has no effect on voltage.
Explanation:
The voltage of the battery in your car is always 12 to 13.5 volts. It makes no difference whether the car is home in the garage or zooming down the interstate.
Answer: 74.8m
Explanation:
We have the vector defined by:
r = 101m
θ = 42.2°
When we want to write this as rectangular components, we have that:
x = r*cos(θ)
y = t*sin(θ)
this is because we can construct a triangle rectangle, where the module of the vector is the hypotenuse, the x component is the adjacent cathetus and the y component is the opposite cathetus.
Then, here we have that the x component is
x = 101m*cos(42.2°) = 74.8m
Answer:
Determining the Slope on a p-t Graph. It was learned earlier in Lesson 3 that the slope of the line on a position versus time graph is equal to the velocity of the object. If the object is moving with a velocity of +4 m/s, then the slope of the line will be +4 m/s
