A block of wood has a volume of 125 cm has a mass of 27 g. What is the density of this block ?
Answers
Answer:
27/125
(3/5)³
(0.6)³
0.216 gm/cm³ or g/cc
Explanation:
- Given:
- Volume = 125 cm³
- mass: 27 grams
Here Density is actually the amount of matter present in unit volume.
- Mathematically, rho(like p) (tapering downwards) = Mass/Volume
- Putting, 27/125 g/cm³
0.216 g/cc

Average speed =
(distance covered during some period of time)
divided by
(length of time to cover that distance).
Answers
Weight is always (mass) times (gravity in the place where you are).
On Earth, acceleration due to gravity is 9.8 m/s² ,
so the person's weight is
(80 kg) x (9.8 m/s²) = 784 newtons .

The number of oscillations made by guitar string in each minute will be 30720.
Given data:
The frequency of vibration is, f = 512 Hz.
The given problem is based on the concept of frequency of vibration. This can be defined as the number of oscillation completed in a seconds.
The number of oscillation in 1 second is,
Since, 1 minute = 60 seconds.
So, oscillations in 60 seconds is,
Thus, we can conclude that the number of oscillations in each minute will be 30720.

Answer:
30720 oscillation.
Explanation:
Frequency: This can be defined as the number of oscillation completed in a seconds. The S.I unit of frequency is Hertz.
From the question,
The frequency of the string set is 512 Hz,
These means that the spring set complete 512 oscillation in one seconds
I.e
if its completes in one seconds 512 oscillation.
Then, in one minutes, it will complete x oscillation.
x = 512×1min/1seconds
But 1 minutes = 60 seconds
x = 512×60/1
x = 30720 oscillation.
