Answer:
Explanation:
Let E be the strength of electric field and m be the mass of plastic sphere.
charge on plastic sphere, q = - 3 n C = - 3 x 10^-9 C
The force due to electric field on the charged plastic sphere = q E
The weight of the plastic sphere = m g
where, g is the acceleration due to gravity.
Now the force due to electrostatic field is balanced by teh weight of the plastic sphere.
q E = m g
E = m g / q
E = m x 9.8 / (3 x 10^-9) = 3.26 x 10^9 x m
Substitute the value of m and get the value E.
A) The electrons may jump to a higher energy level.
Answer: Why is 52,427 written as 5.2427 x 104 in scientific notation
PLEASE BRAINLIEST
No because the top has more oxygen to it which will break the particles up and have them freeze easier.
so if something froze at the bottom of the lake it would float to the top and that's why water always freezes from the top down :))
