As Saba was wearing high heels they are long from the bottom so they sank however Sana was wearing snow boots which means they were flat and so she didn’t sink.
Answer:
The correct answer would be B. 18 to 26%.
The muscle efficiency is calculated by dividing mechanical work output by total metabolic cost.
It is estimated that human muscles have an efficiency of about 18% to 26%.
The efficiency is low because most of the energy is lost when food energy is converted into ATP (adenosine triphophate).
In addition, there is second energy loss when energy in the form of ATP is converted into the mechanical energy such as rowing, cycling et cetera.
Answer:
Wave W is a sound wave, Waves X and Y are light waves, and it is impossible to tell what kind of wave Wave Z is.
Explanation:
W travels fastest through metal
X travels fastest through air,
Y travels more slowly through water than air
Z travels more slowly at cool temperatures
W appears to be sound wave as sound travels fastest through metal .
X appears to be light wave as light travels fastest in air .
Y also appears to be light wave as speed of light is reduced when it passes from air to water .
Z It is impossible to tell anything about the nature of Z wave .
Answer:
The amount of heat required is 
Explanation:
From the question we are told that
The mass of water is 
The temperature of the water before drinking is 
The temperature of the body is 
Generally the amount of heat required to move the water from its former temperature to the body temperature is

Here
is the specific heat of water with value
So

=>
Generally the no of mole of sweat present mass of water is

Here
is the molar mass of sweat with value
=> 
=> 
Generally the heat required to vaporize the number of moles of the sweat is mathematically represented as

Here
is the latent heat of vaporization with value 
=> 
=> 
Generally the overall amount of heat energy required is

=> 
=>
