If a concrete column is 6 inches by 6 inches square and 8 ft. long, calculate its weight in Newtons, given a specific weight of
tangare [24]
<h2>Weight of column is 555.83 N</h2>

Step-by-step explanation:

Size of column = 6 inch x 6 inch x 8 ft

Size of column = 0.5 ft x 0.5 ft x 8 ft

Volume of column = 0.5 x 0.5 x 8 = 2 ft³

Specific weight of concrete = 62.4 lb/ft³

Mass = Volume x Specific weight

Mass = 2 x 62.4

Mass = 124.8 lb = 124.8 x 0.454 = 56.66 kg

Weight = 56.66 x 9.81 = 555.83 N

Weight of column is 555.83 N

An aircraft jet engine has a thrust of I80N. What impulse is produced<br> in 30 S?
neonofarm [45]

The impulse that was produced by this aircraft jet engine is 5,400 Ns.

<u>Given the following data:</u>

  • Thrust = 180 Newton.
  • Time = 30 seconds.

To determine the impulse that was produced by this aircraft jet engine:

<h3>How to calculate impulse.</h3>

Mathematically, impulse is given by this formula:

I = Ft

<u>Where:</u>

  • F is the force or thrust.
  • t is the time measured in seconds.

Substituting the given parameters into the formula, we have;

I = 180 \times 30

Impulse, I = 5,400 Ns.

How would I do this?? Will give brainiest
balandron [24]

Answer:

x = 70°

Step-by-step explanation:

<em><u>I will assume solving the problem where 2 parallel lines are cut by a transversal that has an angle 110 and another angle x. Lets solve for x.</u></em>

When 2 parallel lines are cut by transversals, we have 4 pair of equal angles.

Now, looking at the figure,

The angle beside (adjacent) to the angle 110 is same as the angle x degrees.

These are corresponding angles, which are equal.

So, we have 110 degree angle and x degree angle adjacent to each other in a straight line. This is a straight angle.

A straight line (or, straight angle) creates 180 degrees. Thus, we can write:

110 + x = 180

Now, we solve for x:

110 + x = 180\\x=180-110\\x=70

So,

x = 70°
