Answer:
Cars moving at constant speed on a circular race track
Explanation:
Stars and gas in the galactic disk moves in a roughly circular path about the center of the galaxy
Answer:
k=188.46 N/m
Explanation:
Given that
m= 30 gm
Additional mass = ΔM
Lets take spring coefficient = k
at the equilibrium position
F= k Δl =( m + ΔM)g
Δl = change in the spring length
k Δl = ( m + ΔM)g
Δl = m g /k + g/k ΔM ---------------1
We know that equation of line given as
y = c + S x -----------------2
By compare equation 2 and 1
slope = s
S= g/k
Given that slope S= 0.052 m/kg
S =g/ k= 0.052
g=9.8 m/s²
9.8 = 0.052 k
k=188.46 N/m
So the spring constant is 188.46 N/m
Can we see the diagram? Thanks.
Answer:
<h2>For 24 seconds
force exerted is 5092 N towards opposite direction of motion of bus.</h2><h2>For 3.90 seconds
force exerted is 31333 N towards opposite direction of motion of bus.</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 20 m/s
Final velocity, v = 0 m/s
Case 1:-
Time, t = 24 s
Substituting
v = u + at
0 = 20 + a x 24
a = -0.8333 m/s²
Force = Mass x Acceleration = 6110 x -0.8333 = -5092 N
Force exerted is 5092 N towards opposite direction of motion of bus.
Case 2:-
Time, t = 3.90 s
Substituting
v = u + at
0 = 20 + a x 3.90
a = -5.13 m/s²
Force = Mass x Acceleration = 6110 x -5.13 = -31333 N
Force exerted is 31333 N towards opposite direction of motion of bus.
