Answer:
Explanation:
velocity=s/t
given distance is 480 km we have to convert it into meter because the unit of distance is meter
1 km=1000 m
480 km=480000 m =4.8*10^5
1 hour= 3600 s
12 hour =43200 s
now velocity=s/t
v=4.8*10^5/43200
v=11.11 m/s
Answer:
Climate
Explanation:
conditions of the atmosphere at a particular location over a long period of time; it is the long-term summation of the atmospheric elements
Refer to the diagram shown below.
The given data is
mass, kg Coordinates. m
------------- -----------------
2 (0, 0)
2 (2, 0)
4 (2, 1)
Total mass, M = 2+2+4 = 8kg
Let (x,y) be the coordinates of M.
Then, taking moments about the origin, we obtain
8x = 2*0 + 2*2 + 4*2 = 12
x = 1.5 m
8y = 2*0 + 2*0 + 4*1 = 4
y = 0.5 m
Answer: (1.5, 0.5) m
Answer:
Time according to earth clock (T0) = 0.22 years (Approx)
Explanation:
Given:
Time taken by light = 4.5 years
Time taken by ship = 5 years
Speed of light = c
Speed of ship (v) = 90% of c = 0.9c
Find:
Time according to earth clock (T0) = ?
Computation:
Time dilation is ,
Time according to earth clock (T0) = 0.22 years (Approx)
