Answer:
a).
b).
Explanation:
a).
The work of the spring is find by the formula:
So knowing the work can find the constant K'
Solve for K'
b).
The force of the spring realice a motion so using the force and knowing the accelerations can find the mass
Yeah lowkey i think it’s B
Answer:
Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.

Hello!
The removal of vegetation causes the desertification and erosion of soil. The roots of the plants that are inside the soil create a sort of net that prevents the material to be dragged by the water from the rain. They also absorb any excess water that can weaken the soil structure. If vegetation is removed from the soil, the nutrients can be dragged by water currents and slowly the desertification will occur.
Have a nice day!
I’m sorry i haven’t found the answer to this
