10000 dyne into Newton.

Igoryamba

Divide the value by 100000 because;
1 Newton = 100000 Dyne

$\sf\therefore \: 10000 \: dyne = \frac{10000}{100000} = 0.1 \: newton$

A sound from a source has an intensity of 270 db when it is 1 m from the source. what is the intensity of the sound when it is 3

Lina20 [59]

Sound intensity is inversely proportional to the square of the distance between the source and the receiver.
That is
I = k/r^2
where
k = constant
r = radius

When r=1, the intensity is I₁ = k/1 = k
When r=3, the intensity I₂ = k/3² = k/9
Therefore
I₂ = I₁ /9

In decibels,
I = 10 log₁₀(I/I₀)
where I₀ = reference intensity

When r=1,
10 log₁₀ (I₁/I₀) = 270

When r =3,
10 log₁₀ (I₂/I₀) = 10 log₁₀ [(I₂/I₁)*(I₁/I₀)]
= 10 log₁₀ [(1/9)*(I₁/I₀)]
= 10 log₁₀(1/9) + 270
= 260.5

Answer: 260.5 dB (nearest tenth)

How much heat is required to raise 100 grams of water (c= 4.18) by 5 degrees Celsius?

Andrei [34K]

Answer:

Heat capacity, Q = 2090 Joules.

Explanation:

Given the following data;

Mass = 100 grams

Specific heat capacity = 4.18 J/g°C.

Temperature = 5°C

To find the quantity of heat required;

Heat capacity is given by the formula;

$Q = mct$

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

t represents the temperature of an object.

Substituting into the formula, we have;

$Q = 100*4.18*5$

Heat capacity, Q = 2090 Joules.
