Differences b/w an motor n an electromagnet r :
1- motor is a device which converts electrical energy into mechanical energy while an electromagnet is just a combination of a soft iron core + solenoid....
2- electromagnets r strong temporary magnets while motors don't behave like a magnet
Answer:
Nearest, the revolutions per minute will be 29.
Explanation:
Given that,
Radius of circle = 1 m
Acceleration a =g
We know that,
Angular frequency is defined as,
Where, n = number of revolutions in one second
We need to calculate the revolutions in one second
Using formula of centripetal acceleration
Put the value of a and ω
Put the value into the formula
We need to calculate the revolutions per minute
Using value for the revolutions per minute
Hence, Nearest, the revolutions per minute will be 29.
Answer:
Each student gets 4 green stickers and 5 purple stickers or a total of 9 stickers.
Explanation:
The greatest common divisor (GCD) of two or more natural numbers or integers (not numbers with decimals) is the largest number that divides them. In other words, the Greatest Common Divisor is the greatest of the common divisors of several numbers. To calculate it, each of them is decomposed into prime factors. The GCD is the result of multiplying the factors that are repeated in all the decompositions, affected by the smallest exponent.
In the event that no factor is repeated, the GCD of those numbers is 1, and the numbers are said to be "prime to each other."
In this case, the decomposition of 12 and 15 is:
12 = 2²*3.
15=3*5
So the GCD between 12 and 15 is 3
Now, to calculate how many green and purple stickers each student receives, you simply divide the amount of each sticker color by 3.
12÷3= 4
15÷3= 5
So, <u><em>each student gets 4 green stickers and 5 purple stickers or a total of 9 stickers.</em></u>
1. all living things are composed of cells
2. cells are the basic units of structure and function for living things
3. all cells come from pre-existing cells. (organisms grow by adding on more cells, not by increasing the sizes of the cell)
Weeds are very important agronomically because they reduce the yield of crops in three ways: by competing with the crop for water, light and nutrients, by interfering with crop harvest, and by contaminating harvested products with weed seeds and toxins. Weeds can reduce yield up to 50% and are responsible for millions of dollars in crop losses each year.
It’s biotic factor would be competition as Competition can be defined as an interaction between organisms or species, in which the fitness of one is lowered by the presence of another.
