Answer:
Option A is correct
Explanation:
Direction of spin can be measured because of the behaviours of the particle as it goes through a magnetic field and the size of the spin is dependant on type of particle.
Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.
B) The amount of work done
I believe the answer is D
Hope this helps :)
Explanation:
density = mass/ volume
in the question the mass is given in grams so will convert it into kg,
10 g = 0.01 kg
density= 0.01/ 20 = 1 / 2000 = 0.005 kg/m^3
