Answer:
Distance between Ryan home and mountain will be 252 miles
Explanation:
Let the distance from home to mountains is d
It is given that it took 7 hours to go mountains from home
Let the speed in going to mountain is v
Then according to question speed in coming from mountain is v+27
And time taken in come from mountain to home is hour
As distance will be same in both case
Distance will be equal to
So
v = 36 miles per hour
So distance will be equal to
Answer:
Minimum percentage error = 20%
Explanation:
The zero error of the screw gauge is
(5*0.5)/50 = 0.05 mm
Least count on the circular scale is 0.5/50 = 0.01 mm
Equivalent circular scale reading = 0.01 * 25 = 0.25 mm
Reading on the main scale = 2 * 0.5 = 1 mm
Actual measurement = 1 +0.25-0.05 = 1.20 mm
The minimum percentage error in the reading will be (1.20 mm -1.00 mm)/1*100 = 20%
Answer:
v = 7121.3 m/s
Explanation:
As we know that the centripetal force for the space shuttle is due to gravitational force of earth due to which it will rotate in circular path with constant speed
so here we will have
here we know that
r = orbital radius = 6370 km + 1482 km
also we know that
now we will have
The human is a pedestrian
