It is not possible for an object to have no external/internal forces acting on it. To have an acceleration of 0, the forces acting on the object balance out, leading to the object remaining static.
Hope I helped :)
Answer: The period of the pendulum will be bigger than in Earth.
Explanation:
The period of a pendulum is:
T = 2*pi*√(L/g)
where pi = 3.14
L is the length of the pendulum and g is the gravitational acceleration.
you can see that g is in the denominator, so if g is smaller, then the end number woll be bigger (because in the moon we are dividing by a smaller number)
This means that in the moon the period of the pendulum is bigger than in the Earth.
Answer:
5. independent of its amplitude.
3. inversely proportional to its acceleration
Explanation:
The time period of oscillation is mathematically given as:
where:
length of the string through which the body oscillates.
acceleration due to gravity.
So, we can observe that it is independent of amplitude and depends on acceleration due to gravity and the length of the oscillating string.
Answer:
Explanation:
As per Doppler's effect of sound the frequency of the sound when source is approaching the observer is given as
similarly when source is moving away from the observer then its frequency is given as
now we know that the ratio of two frequency is
The object is not accelerating. I think I got this question right
