Answer:
500 cal
Explanation:
m=25g,c=1cal/g, change in temperature=70-50,20 degree Celsius Q=?
using formula Q=mxcx change in theta
Q=25x1x20
Q=500cal
The density in lbs/in³ units : 0.697
<h3>Further explanation</h3>
Given
Density of gold is 19.3 g/cm³
Required
Conversion to lbs/in³
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
Conversion factor
1 g = 0,00220462 lbs
1 cm³ = 0,0610237 in³
So the density :
Anabolic steroids aid in muscle development... these are VERY different from corticosteroids
The answer is 50 kcal by the formula of 10% - 500kcal x .1 = 50 kcal it is the approximately chemical energy that can contain by the secondary consumers.
1%- 500,000 kcal x .01 = 5,000 kcal for producers.
10%- 5,000 kcal x .1 = 500 kcal for primary consumers.
10%- 500 kcal x .1 = 50 kcal for secondary consumers.
10%- 50 kcal x .1 = 5 kcal for tertiary consumers.
Each trophic level receives less and less energy, so fewer organisms can be supported at higher levels.
10% of energy gets passed to next level in form of chemical bonds and 1 decimal place.
