B. Transverse Wave this is the correct answer
There is no image!?...was there meant to be something attached?
Answer:
solution:
to find the speed of a jogger use the following relation:
V
=
d
x
/d
t
=

in Above equation in x and t. Separating the variables and integrating,

Here C =constant of integration.
x

, we get: C
=

4.7619
now we have the relation to find the position and time for the jogger as:

Here
x is measured in miles and t in hours.
(a) To find the distance the jogger has run in 1 hr, we set t=1 in equation (2),
to get:
= −

(b) To find the jogger's acceleration in m

differentiate
equation (1) with respect to time.
we have to eliminate x from the equation (1) using equation (2).
Eliminating x we get:
v
=

Now differentiating above equation w.r.t time we get:
a

(c) required time for the jogger to run 6 miles is obtained by setting

If the corner is rounded and is perfectly circular, then the acceleration is centripetal and is always directed toward the center.
Answer:

Explanation:
When the springs are connected end to end, it means they are connected in series. When the springs are connected in series, the stress applied to the system gets applied to each of the springs without any change in magnitude while the strain of the system is the sum total of strains of each spring. The spring constant of the resultant system is given as,

Here, n = 10
Spring constant of each spring = k
Thus,
