Answer:
a) 4.40 s
b) 2.20 s
Explanation:
Given parameters are:
At constant power ,
initial speed of the car, 
final speed of the car,
mph
At full power,
initial speed of the car, 
final speed of the car,
mph
a)
At constant power, 
At full power, 
So 
So, time to reach 64 mph speed is 4 times more than the initial time
s
b)

For final 64 mph speed,
=
s

The most probable answer for this question would be that almost every life process requires specialized cells in multicellular organisms. To simply put it, cells of multicellular organisms are specialized in a way that they are all grouped into their respective tissues and these tissues are all grouped into their respective organs and these organs are all grouped together into their respective systems and these systems make up the multicellular organisms. These systems have their own functions in maintaining and sustaining the life that the organisms has. The organs have their own functions as well, thus specialized cells are mostly needed in respiration, digestion, circulation, movement, excretion, reproduction, immunity, coordination, and synthesis.
(10 waves) / (5 sec)
= (10/5) (wave/sec)
= 2 per sec
= 2 Hz .
Answer:

Explanation:
Considering an object that moving about in a circular path, the equation for such centripetal force can be computed as:

The model for the person can be seen in the diagram attached below.
So, along the horizontal axis, the net force that is exerted on the person is:

Dividing both sides by "m"; we have :

Making "v" the subject of the formula: we have:


So, when
= 0; the velocity is maximum
∴




Hence; the maximum walking speed for the person is
