How many meters in 2.50 miles? (Use these two conversions: 1000 m = 1 km and 1.00 km = .621 mi )
1 answer:
2.50 miles is equal to 4026 m.
<u>Explanation:</u>
As it is known that 1000 m =1 km and 1 km = 0.621 miles. So first we have to convert miles to km and then to metre as follows.
As 1 km = 0.621 miles, then
So, 2.50 miles will be equal to
Then, in order to get the answer in meters, we have to convert this km to meter by the conversion of 1000 m =1 km. So,
Thereby,

Explanation:
The height of the rise of liquid with capillary tube is given by the formula as follows :
Where
r is radius
It is clear that the height of the rise of liquid is inversely proportional to the radius of the capillary tube.
If the radius of the capillary tube is doubled, it means the height of rise of liquid with capillary tube become half.
Explanation:
x = 3.00 – 2.00t + 3.00,
Distance of object at 2 second,
x (t=2) = 3(4) - 2(2) +3
x (t=2) = 12-4 +3
x (t=2) = 11 m
Distance of object at 3 second,
x (t=3) = 3(9) - 2(3) +3
x (t=2) = 27 - 6 + 3
x (t=2) = 24 m
a) the average speed between t = 2.00 s and t = 3.00 s,
Average speed =
Average speed =
Average speed =
Average speed =
Average speed = 11.66
b) the instantaneous speed at t = 2.00 s and t = 3.00 s,
Instantaneous speed =
Instantaneous speed(v) = 6t - 2
Instantaneous speed,v(t=2 to t=3) = 18-2-12+2
Instantaneous speed, v = 6
c) the average acceleration between t = 2.00 s and t = 3.00 s
average acceleration =
average acceleration =
average acceleration = 11.66
d) the instantaneous acceleration at t = 2.00 s and t = 3.00 s
instantaneous acceleration =
instantaneous acceleration =6
instantaneous acceleration = 6
e) for x =0
0 = 3.00 – 2.00t + 3.00
a = 3, b=-2, c=3
t=
t=
t=
general solution of this equation gives imaginary value. Hence, the given object is not at rest.
