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:
340 meters
Explanation:
For this we have to use the formula of constant velocity motion:
Because you hear the blows exactly 1 per second. And you hear only one blow after she finished, the sound takes one second to get to you.
I think it's mass...
The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object. Mass is related to how much stuff is there and weight is related to the pull of the Earth (or any other planet) upon that stuff.
I think it should be option (b)
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
