Answer:
but for helping we need yr ques nd they r not here
P=mv
pi =pf
(68x2.79)+(131x0) = 199v
v= 0.95 m/s
Answer:
125 / 500 = 1/4 of the sample left after 3.0 yrs
1/2 * 1/2 = 1/4 sample has decayed thru 2 half-lives
2 * HL = 3
1 Half-Life = 1.5 yrs
That's called the wave's "wavelength" .
To solve this problem we will use the concepts related to the resulting Vector Force product of two components, that is,

If we take the Force of 50 N as the force in the X direction and the Force of 40 N in the Y direction we will have to:



Finally, since Newton's second law, acceleration can be determined as




Therefore the resultant magnitude of the acceleration of the object is
