Answer: Here's your answer: The great uses of Electromagnetism in Life. Whatever powered devices we use, from table clocks to microwave ovens, have some form of electromagnetic principle involved in their functioning. It is electromagnetism which has given the flexibility for switching of/on electricity as required.
Explanation: Yw and mark me as brainiest
Given: v0= 18.0 m/s, y0=0m, yf=11m, g=-9.81 m/s^2
v0= initial velocity, vf= final velocity, y0= initial height, yf= final height, g= gravity, sqrt()= square root, ^2=squared
vf^2=v0^2 + (2)(g)(yf-y0)
vf^2=(18.0 m/s)^2+(2)(-9.81 m/s^2)(11 m-0m)
vf^2=18.0 m/s)^2 + (-19.62 m/s^2)(11 m)
vf^2=(324 m^2/s^2) - (215.82 m^2/s^2)
vf^2=108.18 m^2/s^2
vf=sqrt(108.18 m^2/s^2)
vf=10.4 m/s
Answer:
434.16 Joules
Explanation:
u = Initial velocity
v = Final velocity
m = Mass of person
From work-energy theorem
The runner loses 434.16 Joules of mechanical energy.
He slides 0.94364 m
Answer:
The equation which define the work done by spring is w = 45 x³ - 8 x²
Explanation:
Given as :
The force is the function of distance x
I.e F(x) = a x² - b x
where
a = 45 N/m²
b = 8 N/m
Now, Wok done = Force ×displacement
I.e W = F . ds
So , W = (a x² - b x) × x
or, W = (45 x² - 8 x) × x
Or, w = 45 x³ - 8 x²
So, the equation which define the work done by spring is w = 45 x³ - 8 x²
Hence The equation which define the work done by spring is w = 45 x³ - 8 x² Answer
