Question

the speed of a car as a function of time is show in fig(3-E1) find the distance travelled by the car in 8 sec and its acceleration​

Answer 1

Answer:

as, a=dTdV 

and also slope=dxdu=dtdv

∴ slope=a=410=820

∴a=25m/s2

Now, S=ut+21at2

∴S=0+21×25×64

S=80m

Answer 2

The bohr magneton is defined as the magnetic dipole moment associated with an atom due toThe Bohr magneton μB is a physical constant and the natural unit for expressing the magnetic moment of an electron caused by either its orbital or spin angular momentum.
