Answer:
36.9 m/s
Explanation:
From;
v^2 = u^2 + 2as
Where;
v = final velocity =?
a = acceleration = 3.4 m/s^2
u = initial velocity = 0 m/s
s = distance covered = 200 meters
v^2 = 0^2 + 2 * 3.4 * 200
v^2 = 1360
v = √1360
v = 36.9 m/s
Answer:
Explanation:
Option c is incorrect i.e. Entropy of an isolated system must be conserved
The entropy of an isolated system always increases. This can be explained by considering the system is isolated so there is no exchange of mass i.e. entropy cannot decrease so it must either increase or remains constant. But due to the presence of spontaneity in the system, there is always an increase in mass unless the system is undergoing a reversible process in which each state change is in equilibrium condition.
<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.
