Answer:
Explanation:
Kinetic energy is the energy due to changes in position of a body. It is always with regards to motion of a body.
Potential energy on the other hand is the energy at rest of a body.
To estimate kinetic energy, we use the formula:
K.E = 
where m is the mass of the body and v is the velocity of the object.
mass is 5kg and velocity is 5ms⁻¹
K.E = 
K.E = 62.5J
for the object at rest;
potential energy is calculated:
P.E = mgh
where m is the mass, g is the acceleration due to gravity and h is the height
m is 5kg, h is 2 and g is 9.8
P.E = 5 x 9.8 x 2 = 98J
The moving object has kinetic energy with the object at rest having potential energy.
The structures shown are examples of Constitutional Isomer.
In Chemistry, an isomer refers to a molecule that is similar to another but has differences. These differences can be:
- A difference in the constitution: The molecules have the same formula but the connectivities between elements or arrangement is different.
- Arrangement in space: The molecules have the same formula and connectivity, but they look different to do an arrangement in space of a position.
The molecules shown have the same formula because the elements in each pair are the same. However, the way these elements are connected is slightly different because the Br and the CH3 are connected to different carbons.
Based on this, the difference is the connectivity or constitution, and therefore these are constitutional isomers.

" There will be a net movement of oxygen from outside the cell to inside the cell " Statement is True.
Explanation:
The partial pressure for oxygen in alveoli is greater under normal circumstances, and oxygen moves neatly into the blood. In addition, the partial carbon dioxide pressure throughout the blood usually is higher, such that carbon dioxide migrate clearly into the alveoli.
The few common molecules which can traverse the cell membrane by absorption (or diffusion of a sort recognized as osmosis) are water, carbon dioxide and oxygen. Metabolism is typically oxygen-needed, which is lowest in the cell within the animal and plant, so that net oxygen flows to the cell.

Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
