marishachu [46]
<h2>Average speed of transit train is 60 mph</h2>

Explanation:

Average speed of passenger train = 45 mph

Time taken from station A to station B for passenger train  = 10:00 - 6:00 = 4 hours

Distance between station A to station B = 45 x 4 = 180 miles.

Time taken from station A to station B for transit train  =  4 - 1 = 3 hours

Distance between station A to station B = Average speed of transit train x Time taken from station A to station B for transit train

180 = Average speed of transit train x 3

Average speed of transit train = 60 mph

Average speed of transit train is 60 mph

Cumulative Problem 1
Marrrta [24]

Answer:

Volume, V=696.55\ \mu m^3

Explanation:

Given that,

The diameter of a human cell is 11 μm

It is enclosed by a membrane that is 4,4 nm thick.

We need to find the volume of the cell. The cell is spherical in shape. The volume of a sphere is given by the formula as follows :

V=\dfrac{4}{3}\pi r^3

r is the radius of the sphere, r = 5.5 μm

So,

V=\dfrac{4}{3}\times 3.14\times (5.5)^3\\\\V=696.55\ \mu m^3

So, the volume of the cell is 696.55\ \mu m^3.

Lubov Fominskaja [6]

Applying

v=u+a.t

(all the symbols are bearing their conventional meaning)

Here,u=2ms−1,t=5,a=4ms−2

So,v=2+4⋅5=22ms−1
