Answer:
•→ The motion of a particle or body in S.H.M acts towards a fixed point.
•→ Acceleration of the body under S.H.M is proportional to its displacement.
•→ This motion is periodic.
•→ Mechanical energy is conserved in S.H.M
Explanation:
S.H.M is Simple Harmonic Motion

 
        
                    
             
        
        
        
Answer:
Explanation: so how many minutes are in an hour 60 right, and the bus travels 10km in 7 minutes right so use math the bus travels 14km in 10 minutes so the bus travels 98km in an hour
 
        
             
        
        
        
<span>A= a=99/85.3 
B= a=-54/85.3 
C=The acceleration is smaller.

Answer:
(a) 61.25 N 
(b) 6.25 kg
(c) 6.25 Kg
Explanation:
Weight on moon = 10 N 
Acceleration due to gravity on moon = 1.6 m/s^2 
Acceleration due to gravity on earth = 9.8 m/s^2 
Let m be the mass of the package.
(a) Weight on earth = mass x acceleration due to gravity on earth 
Weight on earth = 6.25 x 9.8 = 61.25 N
(b) Weight on moon = mass x acceleration due to gravity on moon
10 = m x 1.6 
m = 6.25 kg 
(c) Mass of the package remains same as mass does not change, so the mass of package on earth is 6.25 kg.
 
        
             
        
        
        
Answer:
5.959 m/s
Explanation:
m = Mass of gymnast
u = Initial velocity
v = Final velocity
 = Initial height
 = Final height
From conservation of Energy



Velocity of gymnast at bottom of swing is 5.959 m/s
