Answer:
Useful Output = 35 J
Explanation:
The useful energy output of the car must be equal to the difference between the total input energy supplied to the car and the energy wasted by the car:
Useful Output = Total Input - Waste
where,
Total Input = 120 J
Waste = 85 J
Therefore,
Useful Output = 120 J - 85 J
<u>Useful Output = 35 J</u>
The concepts necessary to solve this problem are those given by the kinematic equations of motion. We will apply the speed as a unit of distance traveled in a given time.
The total distance of 50 miles is traveled with a speed of 34mph in the time 
and the distance of another 50 miles is traveled with a speed 66mph in the time 
.
Determine the value of as follows.
Where t=time, d=distance, v= Velocity
Determine the value of as
Therefore the total time taken is
The above result is the total time taken to reach the grandmother's house
Now the average velocity is
Therefore the average speed on the way to grandmother's house is 44.87mph
You will get 20460000 as your answer which is broken down into, 2.046 x 10^7 as your number has to be between 1-10.
They cause magnetic storms. A magnetic storm is a fleeting
disturbance of the Earth's magnetosphere. A magnetic storm is caused by a solar
wind shock wave associated with solar coronal mass ejections, coronal holes, or
solar flares. It typically strikes the Earth's magnetic field 24 to
36 hours after the event.
Answer:
the total cross-sectional area of the capillaries is greater than the total cross-sectional area of the arteries or any other part of the circulatory system.
Explanation:
Blood velocity is not the same in all areas. In the capillaries it is where there is less speed, while in arteries and veins it is quite similar. This is due to the cross-sectional area of each of the vessels. It is a mistake to think of a vein, artery or capillary individually. We have to put them all together to see that the total area of the capillaries is 100 times larger than that of the arteries or veins. Blood flowing through arteries or veins is going faster because there is less area.
Blood velocity is inversely proportional to each of the areas of its territories. The greater the area, the lower the speed.
