Answer:
v = 1.25 m/s
Explanation:
We have,
Distance covered by a person is 10 meters
Time taken by him to cover that distance is 8 seconds.
If we want to find the speed of a person, we must know distance covered by it and taken. In this case, we know both distance and time. His speed is given by :
So, the speed of the person is 1.25 m/s.
Answer:231.16 N/C
Explanation:
Given
Electric Flux
Area(A)
Given Field point above 
Therefore angle between Area vector Electric Field =90-31.6=
We know that Flux is given by
E=231.16 N/C
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:
<h2>468,750 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>468,750 J</h3>
Hope this helps you
Because the more advances made in the world means the more we can learn on how things work and how we can better the lives of humans and other species. If we didn't have scientific advancements we wouldn't have cell phones, electric, tv, car, computers, ect. We would still be living in Cave man era with clubs and horrible language skills.
