You can describe the location of any event ... past, present, or future... with
four numbers, representing the four dimensions of the universe we live in.
The numbers are the three space coordinates of the event ... the 'x', 'y', and 'z'
of its physical location ... and the 't' of its location in time.
Answer:
M = 3.485 kg
m = 1.605 kg
Explanation:
F = 0.98 x 10^-8 N
r = 19.5 cm = 0.195 m
M + m = 5.09 kg ...... (1)
By use of Newton's gravitational law
F = G m1 m2 / r^2
0.98 x 10^-8 = 6.67 x 10^-11 x M x m / (0.195)^2
M x m = 5.59
M - m = 1.88 .........(2)
By solving the equation (1) and equation (20, we get
M = 3.485 kg
m = 1.605 kg
Answer:
It starts from rest so Vi=0
Vf=10 m/s
t=5 seconds
Explanation:
a=Vf-Vi/t
a=10-0/5
a=10/5
a=2m/s^s
