The relative density of oak wood is 0.64 .find the density in the cgs system

Physics

Relative density is defined as:
 dr = ds / dw
 where:
 dr: relative density
 ds: density of the substance.
 dw: density of water.
 In this case we have the relative density of oak wood:
 dr = 0.64.
 We want to find the density of the substance: ds
 Therefore we need to know the density of water in the cgs unit system:
 dw = 1g / c ^ 3
 Finally:
 ds = dr * dw
 ds = 0.64 * 1 g / cm ^ 3
 ds = 0.64 g / c ^ 3
 The density of the oak wood in cgs is 0.64 g / cm ^ 3

3. Some guitarists like the feel of a set of strings that all have the same tension. For such a guitar, the G string (196 Hz) ha
Vlad [161]

Answer:

0.98 g/m

Explanation:

Note: Since Tension and frequency are constant,

Applying,

F₁²M₁ = F₂²M₂............... Equation 1

Where F₁ = Frequency of the G string, F₂ = Frequency of the A string, M₁ = mass density of the G string, M₂ = mass density of the A string.

make M₂ the subject of the equation

M₂ = F₁²M₁/F₂²............... Equation 2

From the question,

Given: F₁ = 196 Hz, M₁ = 0.31 g/m, F₂ = 110 Hz

Substitute these values into equation 2

M₂ = 196²(0.31)/110²

M₂ = 0.98 g/m

a load of 800 newton is lifted by an effort of 200 Newton. if the load is placed at a distance of 10 cm from the fulcrum. what w
nataly862011 [7]

Answer:

40 cm

Explanation:

We are given that

Load=800 N

Effort=200 N

Load  distance=10 cm

We have to find the effort distance.

We know that

load\times load\;distance=Effort\times effort\;distance

Using the formula

800\times 10=200\times effort\;distance

Effort distance=\frac{800\times 10}{200}

Effort distance=\frac{8000}{200}

Effort distance=40 cm

Hence,  the effort distance will be 40 cm.
