If the object is in equilibrium that means that the sum of the forces on it is zero and the net force is zero. If none of the forces changes then the object continues in constant uniform motion. That means constant speed in a straight line.
Answer:
Your hands get warm by fire because chemical energy gets converted into heat energy. When the chemical bonds in the wood are released in the air which then mixes with oxygen and emit heat. This is the reason why it is always hot when you go near something that is burning or is up in flames.
Explanation:
Answer:
The kinetic energy is 
Explanation:
From the question we are told that
The potential difference is 
The potential energy of the end is mathematically represented as

q is the charge on an electron with a constant value of 
substituting values


Now from the law of energy conservation
The 
Where
is the potential energy at the end
So

The negative sign is not includes because kinetic energy can not be negative
With these questions, drawing it out would always help, the answer for this would be 90m if you add them all up. If it’s displacement, it would be 30m. But since it’s asking for the distance TRAVELED then it’s 90m
ANSWER: 90m
A chart that organizes all elements by their atomic number.
