Answer:They may cause motion to change
Explanation:They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.
Answer:
β= 57.99 south of east
Explanation:
?
Velocity in axis x the two balls come one from east and west
Velocity in axis y initial is zero so:
Angle is find using:
tan(β)=
Answer: 1) Cold water is more dense and will sink in room temperature water.
2) Cold salty water is denser than warm freshwater.
3) Temperature is the measure of heat. Density is the measure of how closely any given entity is packed or it is the ratio of the mass of the entity to its volume.
4) Salinity and density share a positive relationship. As density increases, the amount of salt in water-also known as salinity- increases.
If <em>the isotherms</em> are spaced closely together over some portion of the map, there is a drastic temperature change over that portion.
