Answer:
57.8kg
Explanation:
Potential energy is given by:

Where U is potential energy, m is mass, g is acceleration due to gravity, and h is height. Using this equation:

It looks like it is going by 25's so I would say 22.75 mL
Answer:
The correct answer is: X is nitrogen dioxide, and Y is a metal oxide
Explanation:
Combustion of compound of containing nitrogen and metal will give nitrogen dioxide and metal oxide as product. During combustion reaction a compound reacts with oxygen in order to yield oxides of elements present in the compound.
The general equation is given as:

Hence, the correct answer is :X is nitrogen dioxide, and Y is a metal oxide.
SInce earths gravitational force is 9.81, and outer space is less than that, the force decreases
The SI base unit for length is meter.
In order to make smaller measurements, you can use the centi-, milli-, micro-, etc. prefixes.
When you want to reference larger measurements, you can use the kilo-, mega-, giga- and prefixes such as those.
