Answer:
Explanation:
Given
mass of couch
acceleration of couch
inclination
Let coefficient of kinetic Friction
as couch begins to slides Forces act on couch
, where is friction force
therefore net acceleration is
Magnitudes are measured by intensity so a 3.4 earthquake is much less stronger than a 4.5 earthquake it’s very literally when measuring them the higher the number the stronger it is
Answer:
0.7549kg
Explanation:
The mass of the slice + mass of the remaining cake = total mass of cake.
mass of remaining cake = total mass of cake - the mass of the slice
total mass=0.870kg
mass of slice = 0.1151kg
mass of remaining cake = 0.870 - 0.1151
mass of remaining cake=0.7549kg
D would be correct.
Have a merry Christmas!
