Answer: speed is different from velocity and acceleration

Explanation:

Acceleration is rate of change of velocity per unit time and velocity is rate of change of displacement(shortest path between initial and final point) per unit time. but speed is Distance per unit time. The difference between speed and other two terms is that, speed is scalar i.e it has only magnitude, velocity and acceleration has both velocity as well as direction.

  1. a(acceleration) = dv/dt
  2. v(velocity) = ds/dt
  3. speed = distance/time

A 1 m wide continuous footing is designed to support an axial column load of 250 kN per meter of wall length. The footing is pla
creativ13 [48]

Answer:

correct option is (A) 0.5

Explanation:

given data

axial column load = 250 kN per meter

footing placed =  0.5 m

cohesion = 25 kPa

internal friction angle =  5°

solution

we know angle of internal friction is 5° that is near to 0°

so it means the soil is almost cohesive soil.

and for  a pure cohesive soil

N_{\gamma } = 0

and we know formula for N_{\gamma } is

N_{\gamma } = (Nq - 1 ) × tan(Ф)   ..................1

so here Ф is very less  N_{\gamma } should be nearest to zero

and its value can be 0.5

so correct option is (A) 0.5

NARA [144]

Answer: False

Explanation:

The statement that "a person hired by a pharmaceutical company to streamline the company’s drug production process would most likely be an electrical engineer" is false.

An electrical engineer is an engineer that designs, and tests electrical equipment like smartphones, electric motors, etc. The person designs equipments which makes use of electricity or electronics.

He or she doesn't streamline the company’s drug production process, this can be the role played by the production manager.

What is the standard deviation of the following data set:
EastWind [94]

Answer:

See Explanation

Explanation:

The question is incomplete as the data set are missing. However, I'll use the following data to answer your question:

<em>5,12,3,18,6,8,2,10 </em>

Start by calculating the mean:

Mean = \frac{\sum x}{n}

Mean= \frac{5+12+3+18+6+8+2+10}{8}

Mean= \frac{64}{8}

Mean = 8

Standard deviation is calculated using:

SD = \sqrt{\frac{(x_i - Mean)^2}{n}}

This gives:

SD = \sqrt{\frac{(5 - 8)^2+(12 - 8)^2+(3 - 8)^2+(18 - 8)^2+(6 - 8)^2+(8 - 8)^2+(2 - 8)^2+(10 - 8)^2}{8}}

SD = \sqrt{\frac{(-3)^2+(4)^2+(- 5)^2+(10)^2+(-2)^2+(0)^2+( - 6)^2+(2)^2}{8}}

SD = \sqrt{\frac{9+16+25+100+4+0+36+4}{8}}

SD = \sqrt{\frac{194}{8}}

SD = \sqrt{24.25}

SD = 4.92

<em>Apply the above steps in the original question, then you will get your correct answer.</em>
