Answer:
W = 113.98 N
Explanation:
Given that,
Radius of Potatoine
Mass of Potatoine, 
Mass of Marvin, m = 35 kg
We need to find his weight on Potatoine. Weight of an object is given by :
W = mg
g is acceleration due to gravity, 
So,

So, his weight on Potatoine is 113.98 N.

Gravitational Potential Energy of an object is calculated by formula ~

where,
- m = mass of the object = 3500 kg
- g = Acceleration due to gravity = 12 m/s²
- h = height attained by the object = 4 m
Now, let's calculate its potential energy ~
First, let us revise the Law of Conservation of Mass. It states that the total mass in an isolated system remains constant.
The results obtained are not in accordance with this law, because the total mass before the reaction was 75 grams and after the reaction was 73 grams. This seems that there was some mass lost.
This discrepancy is due to the fact that a gas was produced due to the reaction, namely carbon dioxide, and was lost from the beaker into the surroundings.
In order to get results in accordance to the law of conservation of mass, we may simply isolate the system (beaker and reaction mixture) from the surroundings further by putting a cork or some other instrument to seal the beaker.<span />
Answer:
Chemical energy to thermal(heat) energy
Explanation:
A gas burner contains chemical hydrocarbon such as methane, this methane is highly flammable.
The gas burner which contains methane when lighted up converts the chemical energy in the chemical to heat energy through the fire it produces. The fire then helps in heating up the surface it is applied to.
It looks like it's wanting you to find speed and velocity
these formula's should help
speed=distance/time
velocity=overall distance/time
