Why does the needle float when it is dropped in water parallelaly and why it sinks when dropped perpendicularly?
When the needle is dropped parallel to the water's surface, it creates surface tension and stays afloat due to the weight distribution. However, when dropped perpendicularly, the needle displaces more water, causing the weight to overcome the surface tension, thus sinking.
What variables do you think might affect the height to which a dropped ball will bounce?
Variables that might affect the height to which a dropped ball will bounce include the material of the ball, the surface it bounces on, the height from which it is dropped, and the elasticity of the ball. Other factors may include air resistance, temperature, and any external forces acting on the ball during the bounce.
What do you call the transportation of material by water wind ice or gravity?
The transportation of material by water, wind, ice, or gravity is known as erosion. Erosion involves the movement of soil, rock, or other particles from one location to another through the action of natural forces.
What can you infer about the density of a material if a sampleof it floats in water?
If a sample of a material floats in water, it indicates that the material is less dense than water. This means that the material has a lower mass per unit volume compared to water, which has a density of 1 g/cm³.
When this material is placed in a container of water it sinks to the bottom of the container compared to the density of water the density of the material is?
The density of the material is greater than the density of water if it sinks to the bottom of the container when placed in water.
What am i describing when material that has been eroded and transported is dropped by the water wind or ice that was carrying it?
The deposition of sediment.
What is the name of the process by which the material carried by a stream or river settles is dropped?
The process by which the material carried by a stream or river settles or is dropped is called deposition. This occurs when the velocity of the water decreases, causing it to lose the energy needed to carry sediment, which then settles to the riverbed.
Will endust help a phone that has been dropped in water?
A furniture polish will not help. Call your service provider for advice.
A material that is a solid and if dropped in water is very buoyant?
It is a substance that has a low density so that it only needs to displace very little water to equal its weight and so float.
The process in which material is dropped or laid down?
depositation
What is the material that is dropped from streams rivers and lakes?
Sediments.
What nuclear material was used in the bomb that was dropped in nagasaki?
Plutonium
What can be dropped from the tallest building and not break but will if dropped in water?
air bubble
When weathered material is dropped as sediment when a river enters a lake?
sandbars
What formed when rock material is dropped at the front of a glacier?
terminal moranies
Can you appeal out or safe call on dropped third strike?
no
