Answer:
The time taken by the object to reach the ground is 0.58 seconds.
Explanation:
Given that,
An object was released from rest at height of 1.65 m with respect to ground. We need to find the time taken by the object to reach the ground. Initial speed of the object is 0 as it is at rest. It will move downward under the action of gravity such that, the distance covered by the object is given by :
t = 0.58 seconds
So, the time taken by the object to reach the ground is 0.58 seconds. Hence, this is the required solution.
Explanation:
First of all we calculate the volume which is 20m×10m×8m= 1600m^3 and then multiply the density by the volume to get the mass which will equal to 99200kg therefore the weight will be
<em><u>Weight</u></em>
mass × acceleration due to gravity
=99200kg × 10m^s^2
=992000N
Answer:
Tuning a piano is the process of adjusting the tension of its strings, thereby altering their pitch, or frequency of vibration, by slightly turning the tuning pins to which they're attached, so that each string sounds pleasingly in harmony with every other string.
<h2>Hopefully u will satisfy with my answer of ur question..!!</h2>
<h2>Have a nice day ahead dear..!!</h2>
The harmonic frequency of a musical instrument is the minimum frequency at which a string that is fixed at both ends in the instrument may vibrate. The harmonic frequency is known as the first harmonic. Each subsequent harmonic has a frequency equal to:
n*f, where n is the number of the harmonic and f is the harmonic frequency. Therefore, the harmonic frequency may be calculated using:
f = 100 / 2
f = 50 Hz
