Answer:
Total kinetic energy of entire system is 3 mgl
Explanation:
Given two masses: m and 4m.
Since the pulley is frictionless and the thread is massless, the energy here is linked to the two masses.
Total kinetic energy of entire system = decrease in gravitational potential energy of the system.
Therefore, we have :
ΔKE = Δp
ΔKE = 4mgl - mgl
= 3 mgl
Total kinetic energy of entire system is 3 mgl
To be honest I’m not really sure cause I’m in 5th grade but the red planet is the sun
Answer:
D) The rubber object will become negatively charged, and the glass object will become positively charged.
Explanation:
Electron affinity of rubber or glass will decide the thing that rubber will get the negative charge or the glass will get the negative charge
As we know that if the electron affinity of a given material is high then that material will not lose its electron while rubbing with some other material.
When we compare rubber and glass then we know that electron affinity of rubber is more as compare to glass.
So rubber will get negative charge when we rub it with glass
so correct answer will be
D) The rubber object will become negatively charged, and the glass object will become positively charged.
