Velocity means DIRECTION and speed.
and if it's going down that's a different direction from up obviously.
Answer: the pitch would be higher than it was at a lower speed because the air in front of the jet is compressed
Reflection. I used the process of elimination. Cleavage and color are properties of a mineral and magnetism is a property as well you just can’t find strong traces of it in all minerals. But it’s there no matter how weak or strong it’s attraction is drawn to magnetic fields.
That would be melting. From a liquid to a gas is evaporation, and from a solid directly to a gas is sublimation. From a gas to a liquid is condensation, and from a liquid to a solid is freezing.
It doesn't matter what the object's initial velocity is, or how long
the acceleration lasts. All that matters is the object's mass and
acceleration.
Force = (mass) x (acceleration) =
(5kg) x (15 m/s²) =
75 kg-m/s² = <em>75 newtons .</em>
