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;
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;
Heat capacity, Q = 2090 Joules.
Answer:MA = 15
Explanation:The mechanical advantage for an inclined plane is MA=l/h or length divided by height. So, plugging these variables into the equation would have it set up like this: MA = 30/2. When 30 is divided by 2 you get your answer for mechanical advantage, which would be 15
Answer:
Thickness of each page will be 0.00785 cm
So option (E) will be correct answer
Explanation:
We have given that last page on the book is numbered as 764
So total number of pages in the book ( as each page is numbered in both side )
Total thickness of the book = 3 cm
We have to found the thickness of the each page
So thickness of each page will be
So option (E) is correct option
As the train blows its whistle towards you, the wavelength is shorter than the sound of the whistle at rest.
<h3>What is wavelength?</h3>
Wavelength is the distance traveled by a wave in a given period of time.
Relationship between wavelength, speed and frequency of sound
v = fλ
where;
- v is the speed of the sound
- f is the frequency of the sound
- λ is the wavelength of the sound
As the frequency of the sound increases, the wavelength of the sound decreases.
Thus, as the train blows its whistle towards you, the wavelength is shorter than the sound of the whistle at rest.
