Answer:
h = 0.1 m = 10 cm
u = 0.2 m = 20 cm
v = 0.06 m = 6 cm
m = h'/h = v/u
h'/10 = 6/20
h' = 60/20 = 3 cm
Therefore image height = 3 cm(0.03 m)

Explanation:
an object that's less dense than water floats (eg , ball) because the water it displaces weighs more than the object does. If you've ever tried pushing a beach ball underwater , you've felt this principle in action. As we push the ball down , it pushes back up .
Answer:
The magnetic field is 
Explanation:
Given that,
Speed 
Radius = 0.350 m
We need to calculate the magnetic field
Using formula of magnetic field
Where, m = mass of electron
v = speed of electron
q = charge of electron
r = radius
Put the value into the formula


Hence, The magnetic field is
