Answer:
Δx = 1.2 m
Explanation:
The CHANGE of spring length) (Δx) can be found using PS = ½kΔx²
Δx = √(2PS/k) = √(2(450)/650) = 1.17669... ≈ 1.2 m
The actual length of the spring is unknown as it varies with material type, construction method, extension or compression, and other variables we have no clue about.
Answer:
Tungsten is made of tungsten while Nichrome is made of nickel chromium.
Nichrome is used in the elements of electric
devices.
Tungsten is used to make filament of bulbs.
Nichrome have high resistivity than tungsten.
Tungsten have high melting point than nichrome
Explanation:
Unicellular: An organism that consists of a single cell
Multicellular: An organism with multiple cells
Eukaryotic: A cell that contains a nucleus
Prokaryotic: A cell with no nucleus
Autotrophic: An organism that has the ability to make their own food
Heterotrophic: Organism that cannot create their own food
Asexual reproduction: When an organism has the ability to create offspring without the help of another organism
Sexual Reproduction: When two organisms create an offspring using the gametes
Answer: Hello mate!
lets define the north as the y-axis and east as the x-axis.
Using the notation (x,y) we can define the initial position of the car as (0,0)
then the car travells 13 mi east, so now the position is (13,0)
then the car travels Y miles to the north, so the position now is (13, Y)
and we know that the final position is 25° degrees north of east of the initial position. This angle says that the distance traveled to the north is less than 13 mi because this angle is closer to the x-axis (or east in this case).
This angle is measured from east to north, then the adjacent cathetus is on the x-axis, in this case, 13mi
And we want to find the distance Y, so we can use the tangent:
Tan(25°) = Y/13
tan(25°)*13 mi = Y = 6.06 mi.
