One problem with weight training as a way to improve overall health is that the results of a weight-training program are not measurable.
B.False
Answer:
6.29 meters.
Explanation:
, where v is the speed of wave and f is the frequency of wave.
We are given that ,
The speed of sound is 346 m/s.
i..e v=346 m/s
A sound wave travels at a frequency of 55 H.
i..e f=55
the wavelength would be 6.29 meters.

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.
Answer:
Only the hydrogen needs to be balanced. There are equal numbers of aluminum and chlorine.
Explanation:
I took the K12 test, listened to some other idiot and got it wrong, so this is the correct one.
Hope this helps!
