Answer:B
Explanation: an atom is the smallest particle of an element that can take part in a chemical reaction.
Salt is the solute in that situation
Answer:
400
Explanation:
We divide time (4.5 hours) and speed (1800 miles)
1800÷45=400
Answer:
GPE = 388.08 Joules.
Explanation:
Given the following data;
Mass = 0.550kg
Speed = 335 m/s
Height = 72 meters
We know that acceleration due to gravity, g is equal to 9.8 m/s²
To find the gravitational potential energy;
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;

Where;
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Substituting into the formula, we have;

GPE = 388.08 Joules.
