Unlike metals, many nonmetals are.......a. good conductors of heat and electricity.

b. malleable and ductile.

c. gases at room temperature.

d. shiny.

Answers

Unlike metals, many non-metals are malleable and ductile. Thus, the correct option is B.

What are non-metals?

Non-metals are those metals which lack all the metallic attributes which are found in metallic elements. The non-metals are good insulators of heat and electricity. They are mostly gases and sometimes also liquid. Some of the elements then are even solid at room temperature include Carbon, sulphur and phosphorus.

A malleable material is the material in which a thin sheet can be easily formed through hammering. Gold is the most malleable metal found in nature. In contrast, ductility can be defined as the ability of a solid material to deform under the tensile stress.

Therefore, the correct option is B.

The correct is b: malleable and ductile.

Can someone please describe surface tension to me. Please don't give me the dictionary definition. Thank you

Answers


Surface tension - My definition -

It's exactly what it says - The tension of a surface with a liquid (such as water), caused by the attraction of the surfaces layer ---- I hope this helps ---- I actually did research it and got some of this from a dictionary, but I changed some of it, too.... Sorry if this doesn't help :)

Choose "innate" if the behavior is an innate behavioral adaptation and "learned" if it is a learned behavioral adaptation. A stickleback fish attacks fish with a red belly.

A.
innate

B.
learned

Answers

I'd say innate because there is no sign of being trained to attack specificly red bellied fish

Answer:

A

Explanation:

innate is correct....just took test.

How many resistors are found in this circuit?
A) 0
B) 1
C) 2
D) 3

Answers

Answer:

D.3

Explanation:

Three resistors are found in the diagram. Resistors are represented by a zig-zag line, and they could be light bulbs or a hair dryer.

There are 2 resistors in the circuit. This implies the correct answer is B.

Resistors are components that are commonly used in a circuit. A resistor can be defined as an electrical component that is used in regulating the flow of electrical current in an electronic circuit.

Further Explanation

Resistors can as well be used to provide voltage for transistors. High power resistors are used in the power distribution system and parts of motor control.

Resistors are common components of an electronic circuit and they form an integral part of electronic equipment.

The carbon composition resistors are the most common type of resistor in an electronic device, other types of resistors include

  • Fixed resistors: these are the most commonly used type of resistor. They used particularly in an electronic circuit to set the normal conditions in a circuit.
  • Variable resistor: these resistors are made up of the element of fixed resistors and a slider.  A slider is tapped on the resistor element, which also provides three connections to the component

The fixed resistors are also of different types, and these include

  • Carbon composition
  • Carbon film
  • Metal film resistor
  • Metal oxide film resistor
  • Wire wound resistor
  • Surface mount resistor

Some Other Types of resistor include

  • Light-dependent resistor
  • Thermistor
  • Varistor

Adam's dad takes the parkway to work. It takes him 45 minutes to travel from mile marker 145 where he enters the parkway to his exit at mile marker 98. What is his average speed?1. 62.7 mph

2. 47 mph

3. 1 mph

4. 193.3 mph

Answers

speed=distance/time

see his distance

distance is from 145 to 98
145-98=47 miles

time
60 mins per hour
45 mins =time
time=45/60 hours=0.75 hours



47 miles per 0.75 hours
47/0.75=62.6666666 mph
