The book is in motion and at the moment there is no one pushing it to the right. (Remember: a force is not needed to keep a moving object moving to the right.) The forces acting upon the book are shown below.

How much time does it take for a car traveling at 65 miles/hour to travel 300 miles
galina1969 [7]

Time taken by the car to travel 300 miles is 4.615 hours.

<h3>What is speed?</h3>

The speed of any moving object is the ratio of the distance traveled and the time taken to cover that distance.

Given is the distance d = 300 miles and the speed s = 65 miles/hour, then the time taken t will be

s=d/t

65 = 300/t

t= 4.615 hours

Thus, time taken by the car to travel 300 miles is 4.615 hours.

Learn more about speed.

A water bug is suspended on the surface of a pond by surface tension (water does not wet the legs). The bug has six leg, and eac
Crazy boy [7]

Answer:

m = 2.2 x 10⁻⁴ kg = 0.22 g

Explanation:

The surface tension of water is 0.072 N/m. So in order for the bug to avoid sinking, its weight per unit length of contact must be no more than the surface tension of water. Therefore,

Weight\ of bug\ per\ unit\ length = Surface\ Tension\ of\ Water\\\frac{mg}{L} = Surface\ Tension\ of Water\\m = \frac{(Surface\ Tension\ of\ Water)(L)}{g}

where,

m = mass of bug = ?

g = acceleration due to gravity = 9.81 m/s²

L = Contact length = (contact length of each leg)(No. of Legs) = (5 mm)(6)

L = 30 mm = 0.03 m

Therefore,

m = \frac{(0.072\ N/m)(0.03\ m)}{9.81\ m/s^{2}} \\

<u>m = 2.2 x 10⁻⁴ kg = 0.22 g</u>
