There is an established correlation between the number of chirps of a cricket and temperature. The function is
ln C = -6713.2 / T + 25.868

Where c is the number of chirps per min and T is the temperature in K
We are given
T = 22 C + 273 = 295K

Solving for C
ln C = -6713.2 / 295 + 25.868
C = 22.45 chirps/min

In 21 seconds, the number of chips is
22.45 chirps / min (1 min/60 s) (21 s) = 7.86 chirps <span />

What is the definition of work when net force is parallel to the distance?

goldfiish [28.3K]

Work in general is given by W=F·d where F is the force vector and d is the displacement vector. The dot symbol is the dot product which is a measure of how parallel two vectors are. It can be replaced by the cosine of the angle between the two vectors and the vectors replaced by their magnitudes. If F and d are parallel then the angle is zero and the cosine is unity. So in this case work can be defined as the product of the magnitudes of the force and distance:
W=Fd

Answer:

dV/dt = 9 cubic inches per second

Explanation:

Let the height of the cylinder is h

Diameter of cylinder = height of the cylinder = h

Radius of cylinder, r = h/2

dh/dt = 3 inches /s

Volume of cylinder is given by
