When an object is falling and reaches a constant velocity, the net force on the object is <em>zero</em> (it's not accelerating), and the weight of the object is equal to <em>the force of air resistance against the object</em>. (choice-D)
Explanation:
sound waves go through almost every thing exept solid walls
The speed of an object at rest is 0 m/s. We can use logic to figure this out. Hope this helps!
Answer:
The forces could be gravity, friction between the car and the ground, the force Katie is applying and the normal reaction.
Answer:
Object B has greater density
desity A=20/10=2 g cm^-3 . density B=50/10=5 g cm^-3
the object that has greater mass has the greater density because the volume of the those two objects are same
