Answer:
Examples for Rectilinear Motion
1) The use of elevators in public places is an example of rectilinear motion.
2) Gravitational forces acting on objects resulting in free fall is an example of rectilinear motion.
3) Kids sliding down from a slide is a rectilinear motion.
4) The motion of planes in the sky is a rectilinear motion.
 
        
                    
             
        
        
        
Answer:
100 N
Explanation:
Given that,
Two forces whose resultant is 100newton are perpendicular to each other.
If one of them makes an angle of 60newton with the resultant.

and

The magnitude of force,

or
F = 100 N
So, the magnitude of force is 100 N.
 
        
             
        
        
        
Answer:15metre per second squ
I
Explanation:
acceleration=(final velocity-initial velocity)÷t
acceleration=(180-120)÷4
acceleration=60÷4
acceleration=15 metre per second square
 
        
             
        
        
        
Answer:
B: precipitation seeping through pores and cracks in the ground
Explanation:
Man made wells aren't the main source because their isn't enough of them and morning dew doesn't go in to the ground in one main source.
 
        
             
        
        
        
Since carbon has 4 valence electrons, a total of 4 bonds will be drawn withing methane, one between each H and the center C
