both parallel and perpendicular to the wave.


only parallel to the motion of the wave.

Answers

Answer:

Explanation:

Waves are actually energy passing through the water, causing it to move in a circular motion. ... This phenomenon is a result of the wave's orbital motion being disturbed by the seafloor.

The direction a wave propagates is perpendicular to the direction it oscillates for transverse waves. A wave does not move mass in the direction of propagation; it transfers energy.

only perpendicular to the waves

what happens when a low air pressure seytem meets a high air pressure

Answers

Answer:

The temperature of the air drops to below freezing. 2. The air moves to the low pressure system, creating wind. 3.The precipitation is removed from the air. 4. The air starts blowing in an easterly direction.

Explanation:

Answer:

The slightly inward moving air in low pressure causes air to converge and since it can't move downward due to the surface, the air is forced upward, leading to condensation and precipitation as discussed earlier. The opposite occurs with high pressure.

Answers

Answer:

all solids, liquids and gases have density

The types of matter which property of density can be attributed with are;

.All solids, liquids, and gases have density.

Density can be regarded to as one of the characteristic property of a substance. The density of a substance expressed the relationship that the particular substance has with the mass of the substance as well as its volume which is  how much space it takes up.The mass of a particular atoms, as well as how they are been arranged and their size,  determine the density of a substance.Both solid , liquid as well as gas has density.For instance, density of water is 1000kg/cm^3
