GPE= height x mass x gravitational field strength
5 x 10 x 9,8=490J
Answer:
Hey
Your answer would be
The moon is not visible
due to Earth's shadow=lunar eclipse
The sun is not visible due
to the moon=solar eclipse
The moon is on the side of
Earth opposite the sun=new moon
The moon and sun are on
the same side of Earth=full mon
Whan object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations.
Answer:
-2.478
0.379
11.14
24.78
Explanation:
Angular frequency of spring in harmonic motion is given by?
ω = √(k/m)
ω = √(10/2.2)
ω = √4.54
ω = 2.13 s^-1
If at t=0 the mass is in negative amplitude (x = -A = -2.48 m) then we describe the position with negative cosine
x(t) = -A * cos(ωt)
x(t) = -2.48 * cos(2.13 * 1)
x(t) = -2.48 * 0.9993
x(t) = -2.478
Velocity and acceleration are 1st and 2nd derivative of position
b)
v(t) = Aω * sin(ωt)
v(t) = 2.48 * 2.13 * sin(2.13 * 1)
v(t) = 5.282 * sin2.13
v(t) = 5.282 * 0.03717
v(t) = 0.379 m/s
c)
a(t) = Aω^2 * cos(ωt)
a(t) = 2.48 * 2.12² * cos(2.13 * 1)
a(t) = 2.48 * 4.494 * cos2.13
a(t) = 11.15 * 0.9993
a(t) = 11.14 m/s²
d)
F = -k * x(t)
F = -10 * -2.478
F = 24.78 N
Answer:
Wave X is moving the fastest.
Explanation:
As we know that the speed of the wave is given as the product of frequency and wavelength
so here we will have
now for wave X
now the speed of this wave is
now for wave Y
now the speed of this wave is
now for wave Z
now the speed of this wave is
So correct answer will be
Wave X is moving the fastest.
