Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material

You measure the pressure of the four tires of your car each to be 35.0 pounds per square inch (psi). You then roll your car forw
Oksi-84 [34.3K]

Answer:

Weight of car = 36034.88 lb.ft/s²

Explanation:

We are told the pressure of the four tires of your car is; P = 35.0 psi

Also, the surface area of contact is; A = 32 in²

Thus;

Weight of tires = Pressure × Area

W_tires = 35 × 32

Weight_tires = 1120lb.

To get the weight of the car, we will multiply the tire weight by acceleration due to gravity.

It's value in ft/s² is g = 32.174 ft/s²

Thus;

Weight of car = 1120 × 32.174

Weight of car = 36034.88 lb.ft/s²

avanturin [10]

This question is in two parts. This is not the correct multiple choice options for this part a.

The second part had the option

b)If your bedroom has a circular shape, and its diameter measured 6.32 , which of the following numbers would be the most precise value for its area?

a)30 m^2

b) 31.4 m^2

c)31.37 m^2

d)31.371 m^2

Answer:

A. 17.0 m²

B. 31.4 m²

Explanation:

The formula for the calculation of the area of a rectangle is given as

Area = length x width

The length = 3.547 m

The width = 4.79 m

Then area = 3.547 x 4.79

= 16.990m²

When approximated = 17.0m²

This is the most precise measurement for the area of the bedroom.

B.

We solve b using this formula

Area = pi(diameter/2)^2

= 3.14(6.32/2)²

= 3.14 x 9.9856

= 31.4 m²
