Answer:
current = 8,750
Explanation:
you will need to use the formula i = v/r to get this answer
You would convert from grams to
moles by using the molar mass of the substance. The answer is letter B. for
example, the molar mass Carbon dioxide is 44.01 g/mol. It means that for 1 mole
of carbon dioxide, it contains 44.01 grams of Carbon dioxide.
Answer:
Kinetic energy = 127.89 Joules
Explanation:
Kinetic energy is calculated using the following rule:
KE = (1/2)*v* v^2
Where:
m is the mass = 145 g = 0.145 kg
v is the velocity = 42 m/sec
Substitute in the above equation to get the kinetic energy as follows:
KE = (0.5)(0.145)(42)^2
Kinetic energy = 127.89 Joules
Hope this helps :)
