Answer:
Step-by-step explanation:
step 1
Find out the price of 160 begonias, if she bought them separately
step 2
Find out the price of 160 begonias, if she bought them by the flat
Remember that
One flat are 20 plants
so
For 160 plants are needed
160/20=8 flat
step 3
Find out the difference
Answer:
Semiconductors are somewhere in-between conductors and insulators. This means that they are specific when it comes to conducting electricity meaning that their conduction of electricity varies based on their condition at the time.
For instance, they can conduct electricity when heated.
Properties:
1. Perfect insulator at Absolute Zero.
As mentioned above, semi conductors are better at conducting electricity when they are heated. At Absolute zero - the lowest temperature possible - therefore, these materials would conduct absolutely no electricity thereby making them perfect insulators.
2. More resistance than Conductors but less than Insulators
As mentioned above, they have properties in-between those of insulators and conductors. One of those is their resistance. They can resist more than conductors but less than insulators.
Answer:
Saw this question before. The answer is Anita' square.
Square has only four sides while the others more than four so make sense for the square to have longer sides
Answer:
Step-by-step explanation:
formula for cylinder:V=πr2h
shape of the base: circle
formula for circle: A=πr2
radius: 6.5cm
height: 16cm
V=3.14x6.5^2x16
2122.64cm^3
