Answer:0.2A

Explanation:

First, write KCL

i1-i2-i3=0

Then, replace currents with viltages and resistors.

V2-10v/100-v2/200-v2/400=0

V2-40=0

V2=40v

I hope it was helpful

Which of the following are examples of mutually exclusive events? Group of answer choices
kap26 [50]

Answer:

The correct is answer is <u>All of these</u> because:

  • walking and running at the same time
  • rain and a cloudless sky
  • snow and a temperature of 10° Celsius

are all mutually exclusive events.

Explanation:

walking and running at the same time :

Humans can multi task and engage the brain in coordinating psycho motor, affective and cognitive processes all at once but in the case of activities such as running and walking, it is impossible because, the same organs, neurons and muscles are needed for both activity.  

Rain and a cloudless sky :

Rain occurs after a process of condensation. When the vapor that rises, cools off and form a cloud. Rain happens when the cloud formed dissolves. In other words, rain is clouds in liquid state and there is definitely no rain without a cloud.

Snow and a temperature of 10° Celsius:

Snow is synonymous with extreme cold temperatures usually below 0° Celsius. When it snows, temperature levels ranges from zero degrees to -10° Celsius. Therefore, a temperature of 10° Celsius can never occur when it is snowing.

A specimen of some metal having a rectangular cross section 10.4 mm × 12.8 mm is pulled in tension with a force of 15900 N, whic
marishachu [46]

Answer:

\sigma=0.00151

Explanation:

We apply Hooke's Law as follows :

\sigma= E\varepsilon

where \sigma is the applied stress

#The applied stress is also equal to :

\sigma=\frac{F}{A_o}=\frac{F}{lw}

Where l\ and w are the cross-sectional dimensions.

=>We equate the two stress equations:

E\varepsilon=\frac{F}{lw}\\\\\varepsilon=\frac{F}{Elw}

#We substitute our values in the equation as:

\varepsilon=\frac{15900\ N}{(79\times 10^9\ N/m^2)(10.4\ m\times 10^{-3}\times 12.8\ m\times 10^{-3})}}\\\\\\=0.00151

Hence, the resulting strain is 0.00151
