Answer:
<h2>
38,769.23 miles</h2>
Explanation:
given:
A car is traveling at an average speed of 70 m/s.
find:
How many km would the car travel in 6.5 hrs. ?
solution:
distance = velocity over time
let velocity = 70 m/s
time = 6.5 hrs.
convert velocity 70 m/s into m/h for consistency of units.
<u>70 mi. </u> x <u>3600 sec.</u> = 252,000 mi/hour
sec. 1 hr.
now plugin values into the formula d = v/t
d = <u>252,000 miles/hour </u>
6.5 hours
d = 38,769.23 miles
therefore, the distance travelled in 6.5 hours with a speed of 70 m/s is 38,769.23 miles
The analogous formula for magnetic fields is the Ampere's law.
To find the answer, we need to know about the Ampere's law of magnetism.
<h3>What's Ampere's law of magnetism?</h3>
Ampere's law states that the close line integral of magnetic field around a current carrying loop is directly proportional to the current enclosed within it.
<h3>What's is the mathematical expression of Ampere's law?</h3>
Mathematically, Ampere's law is
B•dl= μ₀I
Thus, we can conclude that the analogous formula for gauss law is the Ampere's law in magnetism.

Answer:
a scientist examines the results and answers the lab question- last choice
Answer:

Explanation:
It is given that,
The number of lines per unit length, N = 900 slits per cm
Distance between the formed pattern and the grating, l = 2.3 m
n the first-order spectrum, maxima for two different wavelengths are separated on the screen by 2.98 mm, 
Let d is the slit width of the grating,



For the first wavelength, the position of maxima is given by :

For the other wavelength, the position of maxima is given by :

So,



or

So, the difference between these wavelengths is 14.3 nm. Hence, this is the required solution.
