Answer:
1. floating water
2. they are equal
3.true
4.pushes back down with the force of 5n
Explanation:
To solve this problem we will apply the principles of energy conservation. The kinetic energy in the object must be maintained and transformed into the potential electrostatic energy. Therefore mathematically


Here,
m = mass (At this case of the proton)
v = Velocity
k = Coulomb's constant
= Charge of each object
r= Distance between them
Rearranging to find the second charge we have that

Replacing,


Therefore the charge on the sphere is 3.6531nC
Newton also understood that white light can be separated into its components because each ray of color is deviated by the glass of the prism by a different amount. He realized, for example, that red light is consistently less deviated than violet light.
Answer:29.4m/s
Explanation: Vf=Vi +at= 0 initial velocity +(9.8)(3)= 29.4 m/s
