Answer:
The velocity could be in any direction, but the acceleration is in the direction of the resultant force.
Explanation:
The ball (assuming that we can treat it as a point mass) must obey Newton's 2nd Law, that states that the acceleration produced by a force, is proportional to the applied force, being the mass the proportionality constant.
As the force is the vector, and the mass an scalar, the acceleration vector must be in the same direction as the force vector.
Velocity, instead, can be in any direction: When an object is speeding up is in the same direction as the acceleration, while if it is slowing down, it has just the opposite.
Answer:
The question is missing something it doesn't say how fast down its going and doesn't show the figure sorry for wasting an answer
Answer:
The correct option is;
The graduate cylinder with more water has more thermal energy because it is holding more water molecules
Explanation:
Given that the thermal energy of the system is the energy possessed by the system by virtue of the increased motion of the particles by virtue of a transfer of heat, when the content of the system is heated
The thermal energy, Q is given by the following equation;
Q = Mass, m × The specific heat capacity, C × The change in temperature, ΔT
Given that the graduated cylinder with more water has more mass and therefore, more water molecules, than the cylinder with less water, the cylinder with more water has more thermal energy.
Explanation:
- In chemical reactions, chemical changes occur.
- Atoms are simply rearranged and new bonds are formed.
- Chemical reactions are driven by a need for atoms to attain stability in their structure.
- In all chemical reactions, a reactant or reactants gives new product i.e new substances are formed.
- Most these reactions are not easily reversible.
- They are usually accompanied by the release of energy.
