Three short square wood blocks measuring 3.5 per side support a machine weighing 29500 lbs. What is the compressive stress in th
Ilya [14]

Answer:

D. 803 lbs

Explanation:

In order to find the compressive stress on all three blocks we first need to find the normal surface area of each:

Surface Area of 1 Block = 3.5 x 3.5

Surface Area of 1 Block = 12.25

Surface Area of all 3 Blocks = A = 3 x 12.25

Area = 36.75

Now, the stress is given by the following formula:

Stress = Force/Area

Stress = 29500 lbs/36.75

Stress = 802.72 lbs

Hence, the correct option will be:

<u>D. 803 lbs</u>

Sopranos can sing notes at very high frequencies—over 1000 Hz. When they sing such high notes, it can be difficult to understand
STALIN [3.7K]

Answer: High frequency= High harmonics= Different formants

Explanation:

We are given that sopranos can sing notes at very high frequencies.

Now, when they sing high notes it is difficult to understand their words.

According to the  concept of harmonics, it is the integer multiple of the fundamental frequency. And formants are the different frequencies which in turn give us different vocalizations.

Now, the frequency is over 1000 Hz this implies that the harmonics will be greater and in turn formants will be different. So, this is the reason it is difficult to understand the words of sopranos when they are singing at very high frequencies.

What describes a sun center solar system
aalyn [17]
If you're looking for the word it's heliocentric but if you're wondering what it is it's just where the sun is the center of the solar system and the planets all revolve around it.

Donny, who has a mass of 75.0 kg, is riding at 25.0 m/s in his truck when he suddenly slams on the brakes to avoid hitting a squ
marta [7]

Answer:

F = 3750  N

Explanation:

Given that,

Mass of Donny, m = 75 kg

Initial speed, u = 25 m/s

He suddenly slams on the brakes to avoid hitting a squirrel crossing the road, final speed = 0

Time, t = 0.5 s

We need to find the force the seatbelt exert on him. The force is given by :

F = ma

a is acceleration

F=\dfrac{m(v-u)}{t}\\\\F=\dfrac{75\times (0-25)}{0.5}\\\\=-3750\ N

So, the force is 3750  N.
