Answer:
A. 1 J=1kg•m^2/s^2
Explanation:
Energy refers to the capacity to do work. According to the International System of units (SI units), energy is measured in Joules.
Energy is represented by the force applied over a distance. Force is measured in Newton (N) and distance in metres (m). Hence, energy is Newton × metre (N.m)
Newton is derived from the SI units of mass (Kilograms), and acceleration (metres per seconds^2) i.e Kg.m/s^2, since Force = mass × acceleration.
Since; Energy = Newton × metres
If Newton = Kg.m/s^2 and metres = m
Energy (J) will therefore be; Kg.m/s^2 × m
1J = Kg.m^2/s^2
Answer:ohhhhhhh I’m confused on this
Explanation:ahhh
<span>Nonnumeric, or conceptual problems, differ from numeric problems in a sense that solutions to conceptual problems do not involve or need calculations. It just need your knowledge on that specific subject and you just have to analyze the question and understand it to answer correctly.</span>
Answer:
The answer is
<h2>0.63 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 47 g
volume = 75 mL
The density is
We have the final answer as
<h3>0.63 g/mL</h3>
Hope this helps you
