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
Answer:
yea you should be correct
Explanation:
Answer:
electron
Explanation:
The energy for particle in a box is given by:
for the system in ground state, n =1
Since, the boxes are identical, L is same for all the three particles.
h is Planck's constant.
Since energy is inversely proportional to wavelength, therefore
Thus, electron has the longest wavelength.
