Answer: The blind spot behind a vehicle is one of the most common causes of collisions while backing up.
Explanation:A blind spot in a vehicle is an area around the vehicle that cannot be directly observed by the driver while at the controls and this can be alleviated by the use of adjustable mirrors.
Wind speed and air temperature are used to calculate a windchill factor.
<u>Explanation:</u>
<u></u>
Wind-chill factor is the reduction of body temperature due to the passing flow of lower-temperature air.
The air temperature value is always higher than the wind chill numbers. the heat index will be used if the apparent temperature is higher than the air temperature.So, Wind speed and air temperature are mainly used to calculate a windchill factor.
There are many ways, the surface loses its heat through conduction, evaporation,radiation, and convection.The rate of convection depends on the difference in temperature between the surface and the fluid surrounding the surface and the velocity of that fluid with respect to the surface. The air around the warm surface will be heated, an insulating layer of warm air forms against the surface.The layer becomes a boundary between two. As the wind speed is high the surface cools down rapidly.
The first one. They are not made of elements. They are elements
For this case we have that by definition, the average power is given by:
Where:
W: It is the work done
t: It's time
According to the data we have to:
So:
Answer:
