Answer:

<h2><em><u>ᎪꪀsωꫀᏒ</u></em></h2>

➪x= √ 85

Explanation:

x²+√4 = 87

=> x²+2 = 87

=> x² = 87-2

=> x²= 85

=> x= √85

How do you get DC current and AC current? from a generator?
grin007 [14]

Answer:

They do that by converting rotating mechanical energy into electrical power. Portable generators use an engine—typically running on gasoline, diesel, or propane, to turn an alternator which produces alternating electrical current or AC.

Prior to science lab, Maria had been drinking a can of soda. When she walked into the lab she set it down on the hot plate at he
Vesnalui [34]

Answer:

The hypothesis as to what happened to the soda and the air in the can are as follows;

The solubility of air in the soda is high at low temperatures, such that air (carbon dioxide, CO₂) is trapped in the soda and when it is drank, it gives it its fresh taste

By placing the can of soda on the hot plate, drives off the air in the soda such that the space directly above the liquid soda is filled with the original air (carbon dioxide), in the soda

By dipping the soda upside down in the sink half filled with water, the soda is cooled down and the air (carbon dioxide) directly above the surface of the liquid soda is reabsorbed into the liquid soda, such that if the lid of the soda is sealed, the vacuum created by the empty space directly above the liquid soda becomes a region of low pressure and the combined pressure from the atmosphere and the liquid level in the sink, causes the can to immediately crushed (deformed).

Viscosity: Blood is about 4 to 5 times ____________ viscous than water. Viscosity of blood depends upon the amount of dissolved
kherson [118]

Answer:more, increased

Explanation:

Blood is four to five times more viscous than water.

Viscosity depends upon dissolved substances in blood and it increases as the amount is increases or if the fluid in the blood decreases.

Viscosity is the resistance offered by liquid to the flow and it also depends upon temperature and it decreases with increase in temperature.

The amplitude of an electric field is 0.4 v/m 23 km from a radio transmitter. What is the total power emitted by the transmitter
ycow [4]

To solve this problem we will apply the concepts related to the relationship between the voltage, the electric field and the distance, once the voltage is found we will use the definition of power, which is defined as the square of the voltage over the resistance. This is,

V=Ed

E = Electric field

d= Distance between the points

Replacing,

V=0.4*23000

V=9200 V

Now applying the relation for power we have,

P=\frac{V^2}{R}

Here

V = Voltage

R = Resistance

Replacing,

P= \frac{9200^2}{377}

P=224509.3 W

Therefore the total power emmited by the transmitter is 224509.3 W
