Answer:
Explanation:Magnetism is a class of physical attributes that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.
As we know that as per Newton's II law we have
here we will have
= change in momentum
= time interval in which momentum is changed
now in order to have least injury during jumping we need to have least force on the jumper
so in order to have least force we can say that the momentum must have to change in maximum time so that amount of force must be least
So we need to increase the time in which momentum of the system is changed
Answer:
air humidity
Explanation:
Air parcel is a blob of air which moves in the atmosphere. For stability, if the air parcel is displaced vertically then it returns to the original position.
The most important points to know of the rising air parcel are the air humidity of the air, the temperature of the air and its dew point. These are the critical information to determine the stability of the air.
The air parcel rises buoyantly as it gets warmer than the surrounding environment.
Explanation:
It is given that,
Wavelength, 
Wavelength, 
We need to find the frequencies from corresponding wavelengths. The frequency of the light is given by :
c is the speed of light
Frequency 1,
Frequency 2,
Hence, this is the required solution.
Vf=V1+at
0=31+a(7)
-31/7=a
a=-4.43m/s^2
Hope this helps.
