I'm at k12 and I just took the test got it right. Physical Science: Unit 2 Test
Answer:
move at constant velocity.
Explanation:
Newton's first law (also known as law of inertia) states that:
"when the net force acting on an object is zero, the object will keep its state of rest or if it is moving, it will continue moving at constant velocity".
In the case of the probe, friction in deep space is negligible, therefore when the engine is shut down, there are no more forces acting on the probe: the net force therefore will be zero, so the probe will move at constant velocity.
Water is more dense then air so it sorta holds the rock as it sinks
Frequency and speed = wavelength.
<span>This reduction happens because potential energy transforms to "thermal energy" and "sound energy"
