Answer: By strengthening cardiorespiratory endurance your body will be able to take in and carry more oxygen. This will result in an increased number of red blood cells and hemoglobin. Your heart rate will also become stronger and be able to pump out larger volumes of blood and distribute the oxygen better.
Explanation:
Answer:
The person must be located in the Equator Line. The maximum centripetal acceleration experienced by a person is 0.0337 meters per square second.
Explanation:
Physically speaking, the centripetal acceleration (
), measured in meters per square second, experienced by a person is defined by the following expression:
(1)
Where:
- Angular speed of the Earth, measured in radians per second.
- Distance perpendicular to the rotation axis, measured in meters.
Since rotation axis passes through poles and distance described above is directly proportional to centripetal acceleration. The person must be located in the Equator Line, which is equivalent to the radius of the planet.
In addition, the angular speed of the Earth can be calculated in terms of its period (
), measured in seconds:
(2)
If we know that 
and 
, then the maximum centripetal acceleration experienced by a person is:
The maximum centripetal acceleration experienced by a person is 0.0337 meters per square second.
Answer:
The middle and end of the string respectively
Explanation:
Rarefaction means region of maximum displacement and compression means region of minimum displacement, hence.
We expect a maximum displacement at the middle of the string because it is said to vibrate greatest at this point and conversely vibrate least at the end point which is the region of compression.
Explanation:
the speed of sound depends on the particles of the medium of the sound wave is moving through because the particles in the solid and tightly packed together South Wales weekly transfers energy from particle to particle in a solid
Answer:
Convection currents form because a heated fluid expands, becoming less dense. ... As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. This cycle establishes a circular current that stops only when heat is evenly distributed throughout the fluid.
