A small 23 kilogram canoe is floating downriver at a speed of 3 m/s. What is the canoe's kinetic energy?
1 answer:
Kinetic energy is defined as the energy the object possess due to its motion. It is the work that accelerates a given body from rest to motion.
Given:
The mass of the canoe is 23 kilogram
The velocity of the canoe is 3 m/s
The kinetic energy can be given by the formula:
KE =
Substituting the given values in the kinetic energy equation
KE =
KE= 11.5 * 9 kg.m^2/s^2
k = 103.5 J
Therefore the kinetic energy of the canoe is 103.5 Joules.

The correct question is as follows:
How do you convert from grams to moles of a substance
1. Divide by the molar mass
2. Subtract the molar mass
3. Add the molar mass
4. Multiple by the molar mass
Answer: In order to convert from grams to moles of a substance divide by the molar mass.
Explanation:
The number of moles of a substance is the mass of substance in grams divided by its molar mass.
The formula to calculate moles is as follows.
This means that grams are converted to moles when grams is divided by molar mass.
Thus, we can conclude that in order to convert from grams to moles of a substance divide by the molar mass.
