A good engineer will create an outline that meets the useful necessities of the venture and after that play out an anxiety examination to get certainty that the tower will be sheltered under the normal scope of working conditions. By then, the outline will be tastefully satisfying to engineers. On the off chance that the customer needs something all the more stylishly cleaned, he may need to utilize a plan authority. A designer who puts feel initially is taking a chance with his expert standing.

How fast is a ball going when it hits the ground after being dropped from a
Umnica [9.8K]

Answer:

Option D.

Explanation:

Data:

  • Height (h) = 9 m
  • Gravity (g) = 9.8 m/s²
  • Velocity Final (Vf) = ?

Use formula:

  • Vf² = 2 * g * h

Replace:

  • Vf² = 2 * 9.8 m/s² * 9 m

Multiply gravity with height:

  • Vf² = 2 * 88.2

Multiply:

  • Vf² = 176.4

Solve the square root:

  • Vf = 13.3

How fast is the ball going?

The speed is going at a speed of <u>13.3 meters per second.</u>

Of the following approximate conversions of celsius into fahrenheit, which is most accurate? a. 24°c almost-equals 75.9°f b. 2°c
Softa [21]

The most accurate among the options is 13°c almost-equals 55.0°f, when you round down 55.4, you get 55.0

Hence, option D) is the most accurate.

<h3>What is Scale of Temperature?</h3>

Scale of temperature is simply a method used in calibrating the physical quantity of temperature in metrology.

Conversion of Celsius into Fahrenheit, Formula is expressed as;

Degree = (0 × 9/5) + 32 = Fahrenheit

First we check each option;

A) 24°c almost-equals 75.9°f

24°C = (24 × 9/5) + 32 = 75.2°F

B) 2°C almost-equals 35.8°f

2°C = (2 × 9/5) + 32 = 35.6°F

C) 34°C almost-equals 92.7°f

34°C = (34 × 9/5) + 32 = 93.2°F

D) 13°c almost-equals 55.0°f

13°C = (13 × 9/5) + 32 = 55.4°F

The most accurate among the options is 13°c almost-equals 55.0°f, when you round down 55.4, you get 55.0

Hence, option D) is the most accurate.

A simple machine has efficiency 90%. What does it mean? No machine has 109 efficiency,why?​
Marrrta [24]

Answer:

<em>Efficiency of a machine is 90% this means that the total energy produced to the machine only 90% is useful and given as a output.</em>

<em>Machines are not 100% efficient because some of the work done by a machine is used to overcome friction</em>
