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.
The position of the sun must be at the horizon in order for the rainbow to appear.
The relative positions of the sun and plane make the rainbow appear as a full circle.
However, if the sun is at the horizon, the shadow of the plane will be behind the plane, not below it; this means that the shadow of the plane will not fall on the earth.

Correct answers:
Explanation:
• It is a satellite that collects data about rain and snow.
GPM is part of NASA's Earth Systematic Missions program and its function is to track precipitation from space with satellites and to provide accurate information of the time, place an amount of rain or snow anywhere in the world.
• Its orbit covers 90 percent of Earth's surface.
GPM has unique perspective on measuring precipitation from space because of their collected satellite retrievals.
• The sensors measure microwaves.
GPM Microwave Imager (GMI) is a sensor that observes the microwave energy emitted by the Earth and atmosphere, so it improves the accuracy of rain and snowfall estimates.
Answer:
Supongo que queremos determinar la carga de la carga de prueba.
Sabemos que la fuerza culombiana entre dos cargas q₁ y q₂, separadas por una distancia R, está dada por:
Aislandolo para una de las cargas, obtenemos:
En este caso sabemos:
fuerza atractiva, por lo que los signos de las cargas son opuestos.
q₁ = 5 mC
R = 35cm
F = 1.5 N
Kc = 9*10^9 N*m^2/C^2
Un primer paso, seria reescribir todos los valores en las mismas unidades.
Sabiendo que:
100cm = 1m
R = 35cm = (35/100) m = 0.35m
Y sabiendo que:
1mc = 1*10^(-6) C
Entonces:
q₁ = 5 mC = 5*1*10^(-6) C = 5*10^(-6) C
Ahora podemos reemplazar esos valores en la ecuación de la fuerza, para obtener el valor de la otra carga:
Y recordar que las cargas tienen signo opuesto, entonces la carga de la carga de prueba es:
q₂ = -4.08*10^-5 C
