What is the speed of a cyclist that rides west 88 km in 32 minutes?

suter [353]

Answer:

The speed of the cyclist is 2.75 km/min.

Explanation:

Given

The distance d = 88 km

Time t = 32 minutes

To determine

We need to find the speed of a cyclist.

In order to determine the speed of a cyclist, all we need to do is to divide the distance covered by a cyclist by the time taken to cover the distance.

Using the formula involving speed, time, and distance

$s=\frac{d}{t}$

where

s = speed

d = distance covered

t = time taken

substitute d = 88, and t = 32 in the formula

$s=\frac{d}{t}$

$s=\frac{88}{32}$

Cancel the common factor 8

$s=\frac{11}{4}$

$s=2.75$ km/min

Therefore, the speed of the cyclist is 2.75 km/min.

A solid conducting sphere of radius 2.00 cm has a charge of 8.84 μC. A conducting spherical shell of inner radius 4.00 cm and ou

AlladinOne [14]

Answer: The electric field is given in three regions well defined; 0<r<2; 2<r<4; 4<r<5 and r>5

Explanation: In order to solve this problem we have to use the gaussian law in the mentioned regions.

Region 1; 0<r<2

∫E.ds=Qinside the gaussian surface/ε0

inside of the solid conducting sphere the elevctric field is zero because the charge is located at the surface on this sphere.

Region 2; 2<r<4;

E.4*π*r^2=8,84/ε0

E=8,84/(4*π*ε0*r^2)

Region 3; 4<r<5

E=0 because is inside the conductor.

Finally

Region 4; r>5

E.4*π*r^2=(8,84-2.02)/ε0
