An isolated conducting sphere has a 15 cm radius. One wire carries a current of 1.0000046 A into it while another wire carries a

current of 1.0000000 A out of it. How long in seconds would it take for the sphere to increase in potential by 890 V?

The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be

kap26 [50]

Answer:

$v = 14.86 m/s$

Explanation:

As we know that the force equation at the top is given as

$\frac{mv^2}{R} = ma$

now we know that

$a_c = 1.5 g$

so we have

$\frac{v^2}{R} = 1.5 g$

$v = \sqrt{1.5 Rg}$

so we will have

$v = \sqrt{1.5(15)(9.81)}$

$v = 14.86 m/s$

denpristay [2]

Initial velocity=u=15m/s
Final velocity=v=10m/s
Time=0.08s

$\\ \sf\longmapsto Acceleration=\dfrac{v-u}{t}$

$\\ \sf\longmapsto Acceleration=\dfrac{10-15}{0.08}$

$\\ \sf\longmapsto Acceleration=\dfrac{-5}{0.08}$

$\\ \sf\longmapsto Acceleration=-62.5m/s^2$

Josie is running her first cross country meet. The race is a distance of 5 km and she has set a goal to finish the race in 21 mi

frutty [35]

Answer:

3.97 m/s

Explanation:

Speed is defined as the distance covered per unit time. Therefore, s=d÷t=d/t

Where d is distance and t is time

Given distance of 5 km and time of 21 minutes the speed would be given by dividing 5 km by 21 min. However, speed is expressed as km/h or m/s or miles per hour etc. So we nees to get our speed in one of these standard units.

Going for m/s

Conversion

1 km has 1000m hence

5 km=5*1000=5000m

1 min has 60 seconds hence

21 min=21*60=1260 s

Speed=5000m÷1260s=3.9682539682538 m/s

Rounded off, s=3.97 m/s
