Answer:
The velocity just before hitting the ground is
Explanation:
From the question we are told that
The initial speed is
The final speed is
From the equations of motion we have that
Where s is the distance travelled which is the height of the cliff
So making it the subject of the the formula we have that
Where a is the acceleration due to gravity with a value
So
Now we are told that was through horizontally with a speed of
Which implies that this would be its velocity horizontally through out the motion
Now it final velocity vertically can be mathematically evaluated as
Substituting values
The resultant final velocity is mathematically evaluated as
Substituting values
Answer:
By a factor 9
Explanation:
The intensity of a sound wave is proportional to the square of the amplitude of the wave:
where
I is the intensity
A is the amplitude of the wave
In this problem, the amplitude of the sound wave is increased by a factor 3:
A' = 3A
So the intensity would change by
So, the intensity would increase by a factor 9.
Answer:
The speed will be "3.4×10⁴ m/s²".
Explanation:
The given values are:
Angular speed,
w = 7200 rpm
i.e.,
=
=
Speed from the center,
r = 6.0 cm
As we know,
⇒ Linear speed,
On putting the estimated values, we get
Now,
Acceleration on disk will be:
⇒
