Answer:
Density stays the same
Explanation:
The density remains the same because cutting the object in half will divide the mass & volume by the same amount. Also, the density of a substance remains the same no matter what size it is.
Answer:
The factors that govern the position of an IR absorption peak includes:
A.)strength of the bond
C.)masses of the atoms involved in the bond
D.)the type of vibration being observed
Explanation:
Infra red spectroscopy covers a range of techniques, mostly based on absorption spectroscopy.
I’d say A yeah I’m pretty sure
Answer:
D. The number of atoms present
Explanation:
In a balanced equation, coefficients always represent the number of atoms present.
The answer is -30 N
The explanation:
- to make the box move. so,the horizontal force must be greater than the frictional force.
-and when the horizontal force applied is 30 N. So, the box will remain stationary if the frictional force is equal in magnitude but opposite in direction to the horizontal force. means frictional force = -30 N
This is also being indicate that vertical force due to gravity is equivalent to the normal force when gravity force = 8 N and normal force =8 , meaning the box does not move vertically.
