<h3><u>Answer;</u></h3>
Cardiac enlargement:
- Left ventricular dilation (volume overload) displaces impulse down and to the left ans increases size more that one space.
-A sustained impulse with increased force and duration but no change in location occurs with left ventricular Hypertrophy and no dilation (pressure overload)
- Pulmonary emphysema which makes it non-palpable from the lung sound overriding heart sound.
<h3><u>Explanation</u>;</h3>
- Apical impulse is a point of maximal impulse; pulsation created as the left ventricle rotates against the chest wall during systole.
- When visible, it occupies the fourth or fifth intercostal space, at or inside the midclavicular line. It occurs during systole (short, normally first 1/2 of systole).
- It is normally 1 ×2 cm in size.
Newton's 2nd law of motion:
Net Force = (mass) x (acceleration) .
The law shows the relationship among an object's mass
and acceleration, and the net force acting on it.
If you know any two of the quantities in the formula,
the law can be used to calculate the third one.
J=joules, c=specific heat, q= energy, and the Tf and Ti are the final and initial temperatures cause I couldn't find a delta sign.
Answer:
Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system remains constant as long as the only forces acting are conservative forces.
Explanation:
A food handler cannot identify if food has been contaminated with pathogens by its smell, look and taste. The best way to ensure food is pathogen-free is to follow safe food handler’s practices.
