Answer:
h = 3.10 m
Explanation:
As we know that after each bounce it will lose its 11% of energy
So remaining energy after each bounce is 89%
so let say its initial energy is E
so after first bounce the energy is
after 2nd bounce the energy is
After third bounce the energy is
here initial energy is given as
now let say final height is "h" so after third bounce the energy is given as
now from above equation we have
a. matter
b. mass
c. weight
d. gravity does not change
e. determined by gravity
f. location determines amount
It's kind of hard for me to explain but to further understand this topic you can google the deference between mass and weight. Both mass and weight are both related to matter to that's why matter is a.
Weight is determined by gravity because you would way less on the moon that doesn't have that much of a gravitational pull. That's why people jump really high on the moon. that's also why the location determines the amount.
Mass however doesn't change by gravity. When you go to the moon you do not loose more of yourself or become smaller, you stay the same size. That is part of mass.
To Find: Diameter of soap bubble =? Solution: By Laplace's law of spherical membrane for a bubble. (Pi– Po) = 4T / r.
The size of the resultant is given by using pythagoras:
C^2 = A^2 + B^2
Since the 30N force and the 40N force act perpendicular to one another.
So: C = sqrt[(30)^2 + (40)^2]
C = 50N and, therefore, may be represented using 5cm
Since all we have as reference are the 2 initially given forces, let's use the angle between the resultant force and one of them to determine the resultants direction:
Taking the 40N force as a baseline (you can imagine it being horizontal).
Since the 40N force is a horizontal projection of the 50N resultant force:
40N = 50N*cos(theta) ; where theta is the angle formed between them
Theta is approximately 36,87° and that is the direction of the resultant force taken with the 40N forces direction as reference.
You can also graphically establish this direction by simply drawing the lines in scale on a piece of paper.
