Answer:
a. X = -Xo
b. Remains same
Explanation:
We can say an Equilibrium Position is a condition in which all acting influences are canceled by others, resulting in a stable, balanced, or unchanging system

Answer:
Because it is winter constellation and lies in the day sky during summer
Explanation:
The celestial sphere or the sky above us has been divided in to 88 different areas just like we have countries on Earth. These areas are known as the constellations. In each area when you join the brightest stars you can imagine a pattern. Orion is also one of these 88 constellations and favorite of many astronomers.
All the constellations are not visible through out the year. The reason is revolution of Earth around the Sun. The constellation which lie behind the Sun will appear in the sky in the day time and thus will be invisible to us. While those which appear in the night sky can be seen. Thus, constellations are also seasonal. Some can be seen in winter and some in summer.
Orion is a winter constellation because it appears in the night sky during winter. During summer it appears in the day sky thus can not be seen.
Answer:
Option (D) is correct.
Explanation:
The balloon lands horizontally at a distance of 420 m from a point where it as released.
Velocity of air balloon along +X axis =10 m/s
velocity of ball=4 m/s along + X axis
the velocity of balloon gets added to the velocity of ball. So the resultant velocity of the balloon=10+4 = 14 m/s
time taken= 30 s
The distance traveled is given by d= v t
d= 14 (30)
d= 420 m
Thus the balloon lands horizontally at a distance of 420 m from a point where it as released.
Answer:
Explanation:
The formula for the potential energy of a dipole placed in an electric field is given by
U = - pE Cos θ
where, θ is the angle between dipole moment and the electric field vector.
For θ = 0°,
initial potential energy, Ui = - pE
For θ = 180°,
final potential energy, Uf = - pE Cos 180 = pE
Change in potential energy
ΔU = Uf - Ui
ΔU = pE - (-pE)
ΔU = 2pE
If we start taking into account the free body diagram, we then start damping motion of a body by means of this equation:
<span>m * d^2 x/dt^2 + c* dx/dt + k* x = 0 </span>
<span>free undamped motion is when (c =0) </span>
<span>therefore </span>
<span>50* d^2 x/dt^2 + 200* x = 0 </span>
<span>w = omega = sqrt(k/m) = sqrt(200/50) = 2 </span>
<span>Then </span>
<span>A*cos(w*t) + B*sin(w*t) = x </span>
<span>find A and B using intial conditions and you will get the rest that you need. Hope this helps</span>
