A wire that is 0.20 meters long is moved perpendicularly through a magnetic field of strength 0.45 newtons/amperes meter at a sp
Natali [406]

Answer:

Given:

length of the wire = 0.20 meters

magnetic field strength = 0.45 newtons/amperes meter

speed = 10.0 meters per second

emf = B * l * v 

B = flux density ; l = length of the wire ; v = velocity of the conductor

emf = 0.45 newtons / ampere meter * 0.20 meters * 10.0 meters/seconds

emf = 0.90 volts

The emf produced is 0.90 volts.

8,9,8,11<br> Mean:<br> Median:<br> Mode:<br> Range
Finger [1]
Mean: add all numbers together and divide by the amount of numbers there are.
8 + 9 + 8 + 11 = 36
36/4 = 9
mean = 9

Median: Find the middle number. Since in this case it has an even amount of numbers, add the two middle numbers and divide by 2
8 + 9 = 15
15/2 = 7.5
median = 7.5

Mode: The number that shows up the most 
Mode  = 8

Range: Subtract the smallest number from the largest number
11 - 8 = 3
Range = 3

hope this helps

A garden store has the following miscellaneous bulbs in a basket:
ArbitrLikvidat [17]
Okay. Since we know that the customer before them bought one of each type of bulb, we can subtract one bulb from each type so now, here is what the store has:

5 amaryllis

6 daffodils

3 lilies

2 tulips

Next, let’s find the probability of the customer picking an amaryllis.

We know there are 5 amaryllis, so we can put that as the numerator.

Next, we have to add up all the flowers to get the denominator.

5+6+3+2

I got 16.

So now we have 5/16

So, that is our answer! 5/16, or as a decimal 0.3125, or as a percentage 31.25%.

Hope this helps! Comment if you have any questions! :)
