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

Physics

Zepler [3.9K]3 years ago

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

What gravitational force does the moon produce
saul85 [17]

Answer:

1.94\cdot 10^{20} N

Explanation:

The magnitude of the gravitational force between two objects is given by the equation:

F=G\frac{m_1 m_2}{r^2}

where

G is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between the objects

The gravitational force is always attractive.

In this problem, we have:

m_1 = 5.98\cdot 10^{24}kg is the mass of the Earth

m_2 = 7.34\cdot 10^{22} kg is the mass of the Moon

r=3.88\cdot 10^8 m is the separation between the Earth and the Moon

Therefore, the gravitational force between them is

F=(6.67\cdot 10^{-11})\frac{(5.98\cdot 10^{24})(7.34\cdot 10^{22})}{(3.88\cdot 10^8)^2}=1.94\cdot 10^{20} N

In electronic circuits:______.
trapecia [35]

Answer:

(a), (c) and (e) s correct.

Explanation:

a. the power used by a circuit is the resistance times the current squared.

The power is given by P = I^2 R, so the statement is correct.  

b. electric and magnetic fields are transporting the energy.

false

c. electrons are transporting the energy.

The energy is transferred by flow of electrons. It is correct.  

d. the power used by a circuit is the voltage times the current squared.

The power is given by P  = V I, the statement is wrong.  

e. the power used by a circuit is the current times the voltage.

The power is given by P  = V I, the statement is correct.
