The kinetic energy of a moving object is calculated through the equation,
KE = 0.5mv²
where KE is kinetic energy, m is mass, and v is the velocity. Substituting the known values in the problem above,
KE = 0.5(55 kg)(16 m/s)²
KE = 7,040 J
Thus, the kinetic energy of the skydiver is approximately equal to 7 kJ.
Answer: ea sports
Explanation:
A compound is a substance that contains two or more elements chemically combined in a fixed proportion. However, it is not an element because it can be broken down into simpler substances – carbon and hydrogen. ... Recall that the components of a mixture can be separated from one another by physical means.
Answer: 100
Explanation:
pH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
a) optimum pH for growing strawberries is 6.5
Putting in the values:
b) optimum pH for growing blueberries is 4.5
Putting in the values:
The ratio of hydrogen ions needed to grow strawberries is to the number needed for blueberries is
Thus the number of hydrogen ions needed to grow strawberries is 100 times the number needed for blueberries.
