The electrical event that immediately precedes blood being ejected to the pulmonary trunk / aorta is called ventricular systole

The pressure of the blood inside the ventricle initially increases when its muscles contract, but it is still too low for the semilunar (pulmonary and aortic) valves to open and allow blood to exit the heart. The blood pressure, however, quickly exceeds that of the atrium, which is now relaxed and in diastole. The tricuspid and mitral valves close as a result of the blood flowing back into the atria as a result of the pressure increase. The amount of blood inside the chamber stays constant since blood is not yet being expelled from the ventricles. called ventricular systole  As a result, the term "isovolumic contraction," sometimes known as "isovolumetric contraction," refers to this early stage of ventricular systole.

How do lines of latitude affect how direct or indirect the Sun’s rays are on the Earth?
IgorLugansk [536]
The technical definition of latitude is the angular distance north or south from the earth's equator measured through 90 degrees. ... Locations at lower latitudes receive stronger and more direct sunlight than locations near the poles. Energy input from the sun is the main driving force in the atmosphere.



The Seasons at Different Latitudes
The seasonal effects are different at different latitudes on Earth. Near the equator, for instance, all seasons are much the same. Every day of the year, the Sun is up half the time, so there are approximately 12 hours of sunshine and 12 hours of night.



When we consider Latitude alone as a control, we know that the low latitudes (say from the Equator to approximately 30 degrees N/S) are the warmest across the year (on an annual basis).

a bus is moving at 22m/s [E] for 12s. Then the bus driver slows down at 1.2m/s2 [W] until the bus stops. Determine the total dis
KatRina [158]
The total displacement is equal to the total distance. For the east or E direction, the distance is determined using the equation:

d = vt = (22 m/s)(12 s) = 264 m

For the west or W direction, we use the equations:
a = (v - v₀)/t
d = v₀t + 0.5at²

Because the object slows down, the acceleration is negative. So,
-1.2 m/s² = (0 m/s - 22 m/s)/t
t = 18.33 seconds
d = (22 m/s)(18.33 s) + 0.5(-1.2 m/s²)(18.33 s)²
d = 201.67 m

Thus,
Total Displacement = 264 m +  201.67 m = 465.67 or  approximately 4.7×10² m.

What is the relation between Physical states of solution and solvent
posledela

Explanation:

The solute does not have to be in the same physical state as the solvent, but the physical state of the solvent usually determines the state of the solution. As long as the solute and solvent combine to give a homogeneous solution, the solute is said to be soluble in the solvent.

A woman and her dog are out for a morning run to the river, which is located 4.0 KM away. The woman runs at 2.5 M/S in a straigh
VLD [36.1K]

River shore is located at distance

d = 4 km

speed of the woman is given as

v_1 = 2.5 m/s

now the time taken by the woman to cover the distance is

t = \frac{d}{v}

t = \frac{4000}{2.5} = 1600 s

for the same time interval the dog will run to and fro with speed 4.5 m/s

so the total distance moved by the dog is given by

d = v* t

d = 4.5 * 1600

d = 7200 m

<em>so the total distance that dog will move is 7200 m or 7.2 km</em>
