Answer:

1.25 N

Explanation:

It will experience friction from the kinetic friction component because it is moving ...there will be no component of static friction.

Ff = F n x  k

   =   (.85)(9.81)  x (.15) = 1.25 N

10%) Problem 7: Water flows through a water hose at a rate of Q1 = 620 cm3/s, the diameter of the hose is d1 = 1.99 cm. A nozzle
Semenov [28]

Answer:

a) A_1 = \frac{\pi d_1^2}{4}

Explanation:

a) the cross-sectional area of the hose would be the square of radius times pi. And since the sectional radius is half of its diameter d. We can express the cross-sectional area A1 in term of diameter d1

A_1 = \pi r_1^2 = \pi (d_1/2)^2 = \frac{\pi d_1^2}{4}

BlackZzzverrR [31]

Answer:

Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.
