Multiply field strength (N/kg) by mass (kg) to get weight (N)

At the start, the car is carrying

4.7 kg * (9.8 N/kg) = 46.06 N

of fuel.

At the end, it is carrying

3.0 kg * (9.8 N/kg) = 29.4 N.

Assuming the car remains completely intact, its weight was reduced by

46.06 N - 29.4 N = 16.66 N.

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.

How can an electron in an atom lose energy to go from a higher energy level to a lower energy level?
Black_prince [1.1K]

Answer:

when a photon is created by an electron in a higher energy level. The electron looses energy and move to a lower energy level.

Explanation:

energy levels refer to various levels of energy possessed by the electrons in an atom. An electron in a higher energy level possesses more energy and more speed that that in a lower energy level. Electrons can move from one energy level to another when they gain energy from the surroundings or loose energy to the surroundings. They leave their energy level to fit into a new level where the energy level is same with the energy they now possess. Electrons hit by a photon tend to move to higher energy levels. But if an electron creates a photon it drops to a lower energy level

The block in the figure below has a mass of 5.1 kg and it rests on an incline of angle . You pull on the rope with a force F = 3
viktelen [127]

42.9°

Explanation:

Let's assume that the x-axis is aligned with the incline and the positive direction is up the incline. We can then apply Newton's 2nd law as follows:

x:\;\;\;\;F - mg\sin{\theta} = 0\;\;\;\;

\Rightarrow mg\sin{\theta} = F

Note that the net force is zero because the block is moving with a constant speed when the angle of the incline is set at \theta. Solving for the angle, we get

\sin{\theta} = \dfrac{F}{mg}

or

\theta = \sin^{-1}\left(\dfrac{F}{mg}\right)

\;\;\;=  \sin^{-1}\left[\dfrac{34\:\text{N}}{(5.1\:\text{kg})(9.8\:\text{m/s}^2)}\right]

\;\;\;=42.9°
