Acceleration is caused by a force acting on a mass.

Mumz [18]

Answer:

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

If it takes a P wave five minutes to travel from the epicenter to a seismic station, approximately how long will it take an S wa

jok3333 [9.3K]

It take approximately 9 minutes for an S wave to travel that same distance that P wave travel in 5 minutes.

P waves, are the first waves to arrive at a seismograph.

An S wave, or shear wave, is a seismic body wave that shakes the ground back and forth perpendicular to the direction the wave is moving.

S-wave is about 1.73 times slower than the P-wave.

Mean arterial pressure is ________ (indirectly/directly) proportional to ________ and ________ (indirectly/directly) proportiona

g100num [7]

Answer: Mean Arterial Pressure is directly proportional to Cardiac Output and Systemic Vascular Resistance and also directly proportional to Central Venous Pressure.

Explanation: Based on the relationship of flow, pressure and resistance, the mean arterial pressure is determined by the cardiac output (CO), systemic vascular resistance (SVR), and central venous pressure (CVP). This relationship is given by:

MAP = (CO x SVR) + CVP

Which is alternatively expressed as:

MAP = CO x SVR (this is because at any point in time in blood circulation, the central venous pressure is always near to zero mmHg.

Due to this direct relationship, any factor affecting the cardiac output and the Systemic Vascular Resistance would cause a corresponding change in the Mean Arterial Pressure.

It is also worthy to note that If Cardiac Output and Systemic Vascular Resistance change reciprocally (inversely) and proportionately, then Mean Arterial Pressure will not change. The plotted graph is one of positive slope.

The whole relationship occurs when blood is pumped out of the left ventricle into the aorta and distributing arteries, creating pressure.

In a liquid, objects denser than the liquid (such as rocks) tend to sink, while objects less dense than the liquid (such as infl

Airida [17]

Answer is given below :

Explanation:

If an object weighs more than the weight of the fluid placed in it it will sink. Then floating, which is directly related to the weight or density of the fluid. A more dense, or heavier fluid is capable of "floating" heavy objects.
Proper floating object should be completely above the liquid surface. All floating objects must have some trapped air and this is the only reason they float. The amount of liquid that an object floats on is important in some way,
The density of an object determines whether it floats or sinks to another material. An object floats if it is less dense than the liquid contained in it. If an object is thicker than the liquid in which it is placed it will sink.
If the density of an object in the fluid is greater than the density. Liquid, the object sinks. If the density is lower than the liquid, the object will float up as the fluid is produced.
The product of the density of the liquid volume during acceleration due to gravity is light energy. Therefore, increasing the density of the fluid increases the light energy.
