Answer: wavelength will increase
Explanation:
Velocity is directly proportional to wavelength,as the velocity is increased, wavelength is also increased
To get the solution you must need to draw a force triangle. Attach the head of the 60N north force arrow with the tail of the 60N east force arrow. The subsequent is the arrow connecting he tail and head of the two arrows.
You get a right angled triangle, and the resultant is (60^2 + 60^2) ^0.5 = 84.85 N or 85 N northeast.
Not pushing yourself hard enough is the answer since your heart rate doesn't even hit your lower minimum.
Pushing yourself to the limit is at your max heart rate.
Just at the right spot is at your max heart rate.
Pushing yourself too hard is above your max heart rate.
The factors that affect vital capacity are :
- Age
- Sex
- Height
- Body mass
- Ethnicity
Explanation:
Vital capacity is the maximum amount of air that a person can exhale once he has filled his lungs with maximum air. So, it is like maximum exhalation after maximum inhalation by a person.
Vital capacity is also equal to Forced Vital Capacity.
Lung usually have their maximum capacity in early adult days and this capacity reduces as the person grows older. So age is the prime factor in this.
A female with same age and height as that of male will have 10-12% less vital capacity than him. So sex is another reason which determines vital capacity.
Person with more height has more vital capacity. This is because lungs capacity is closely related to the third power of person's height.
Person suffering from obesity will have compressed diaphragm, lung and chest cavity , so their vital capacity will be less. So we can say body mass affects vital capacity.
Last factor, ethnicity, is yet to be understood clearly as there is not much evidence of this.
A microscope is an instrument from which you can see the cells of an object.
It helps you to observe the cells of substance.
Powerful microscopes helps better in observing minute particles or bacterias.
Hope it helps...
