Answer:
Fish are divided into three main groups, which include Cartilaginous fish, Bony fish, and Lobe-finned fish.
Answer:
Number of gallons =2 gallon
Explanation:
given data:
rate of gasoline ineurope = 5 euro per liter
total money to buy gasoline = 40 euro
total gasoline an american can buy in europe ![= \frac{40}{5}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B40%7D%7B5%7D)
= 8 litres of gasoline
As given in the question 1 ltr is 1 quarts therefore
Total no. of quarts is 8 quarts
As from question 4 quarts is equal to one gallon, hence
Number of gallons![= \frac{8}{4} = 2 gallon](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B8%7D%7B4%7D%20%3D%202%20gallon)
<span>Calculating for potential energy P.E=mgh
m=mass
g=acceleration due to gravity
h=height
</span>Let the twig's mass be M<span>
</span><span>
therefore at the start, the twig has 200*9.8*M potential energy.
</span>During its fall 40% twig's energy is converted into thermal energy and the remaining <span>60% of this will turn into kinetic energy during the fall, giving us 1176M
Now the equation for kinetic energy, K.E is 0.5*m*v^2
m is mass
v is velocity
Therefore 1176M=0.5*M*v^2 (mass will divide out)
velocity is </span><span>48.49 m/s</span>
