Answer:
6 m/s
Explanation:
momentum= mass times velocity
120 = 20v
v = 120/20
Answer:
define 1 second time
One second is the time that elapses during 9,192,631,770 (9.192631770 x 10 9 ) cycles of the radiation produced by the transition between two levels of the cesium 133 atom. ... One second is equal to 1/86,400 of a mean solar day.
the answer is.......................1,4,5
Answer:
Boundaries between the plates are of three types: divergent (i.e., moving ... Plates are thought to move along the lithosphere-asthenosphere boundary, ... plates include both crustal material and lithospheric mantle material makes it ... crust to the ocean floor where it creates a chain of volcanic islands known as an island arc.
Explanation:
Answer:
Velocity will be 2.886 m/sec
Explanation:
We have given arm length = 0.70 m
And distance from the handle to surface = 15 cm =0.15 m
So total distance r = 0.70+0.15 = 0.85
We know that acceleration is given by 
Here acceleration is acceleration due to gravity so a=g
So 
So velocity will be 2.886 m/sec
