What else can I help you with?
Is a rubber ball a solid?
Yes, a rubber ball is a solid because its molecules are packed closely together, giving it a definite shape and volume.
What is the difference between sponge and foam rubber?
The two terms are sometimes used interchangeably, but foam rubber is often used for rubbers that start off as liquids (e.g., latex, liquid urethanes) and sponge rubber is often used more for solid rubbers (e.g., EPDM, Nitrile (NBR), neoprene).
A solid rubber with a mass of 5.9 grams sinks A hollow rubber ball with a mass of 5.9 floats Why?
Because the hollow ball is larger than the solid one. It displaces enough of the fluid to equal its weight, so it floats.
What type of ball will roll the farthest down the ramp?
A ball with less friction, such as a smooth, hard ball like a metal ball or a marble, will typically roll the farthest down a ramp compared to a ball with more friction, such as a rubber ball or a soft foam ball.
Does the material of the ball affect the way it bounces?
Yes, the material of the ball affects the way it bounces. For example, a rubber ball will bounce higher than a foam ball due to their different elasticity and density. Additionally, the surface on which the ball is bouncing can also impact the bounce.
Is a rubber ball a solid?
Yes, a rubber ball is a solid because its molecules are packed closely together, giving it a definite shape and volume.
What is an everyday object that can represent a nucleus?
Well if you want the whole nucleus your gonna have to build it here are some ideas; macoroni noodles or hardshell noodles;a foam ball or a giant rubber ball;string or yarn; for the question you asked a smaller foam ball or a small rubber ball
What are the chemical properties of a dodge ball?
== The "official" ball for the game is an 8" rubber coated foam ball. The chemical properties of rubber and of foam can vary. There are a lot of different rubber compounds (from vehicle tires to rubber gloves) and a lot of different foam compounds (from cleaning sponges to packing material).
Which meterial using computer mouse ball?
The ball inside older mice - was either solid rubber - or a steel ball with a rubber coating.
Is foam rubber really rubber?
No , foam and rubber are very diffrent .
How do you inflate a rubber ball?
If it is a solid rubber ball it is not inflated. A hollow ball can be inflated. The more pressure inside, the "harder" the ball will be and the higher it will bounce. To much pressure and you risk rupturing the "rubber" bladder.
What is the difference between sponge and foam rubber?
The two terms are sometimes used interchangeably, but foam rubber is often used for rubbers that start off as liquids (e.g., latex, liquid urethanes) and sponge rubber is often used more for solid rubbers (e.g., EPDM, Nitrile (NBR), neoprene).
Why does the rubber ball hits the ground before the foam ball?
Two things affect the balls while falling - Gravity and Air Resistance. Gravity affects both balls equally. Air resistance exerts a similar force on objects of the same size and shape. A Foam ball weighs less so the same amount of air resistance causes a larger slowing effect on a light foam ball than it does on a heavy rubber ball.
If you put place a rubber ball into a box why didn't the ball change its shape explain?
because the ball is a solid object.
What is foam rubber?
Foam rubber it is made up with a foaming agent for creating an air-filledmatrix structure. Those foam rubbers are normally either polyurethane foam or natural foam rubber latex.Foam rubber can also created from chemicals polyol,Latex foam rubber.Used in:mattressesInsulationFurniturePackagingCostumes
Who invented rubber balls?
You need to define the answer. Foam can be confused with bubblly foam (like in the bath, doing the dishes) and then there is Polyurethane foam, what people use as padding for insulation. For Polyurethane foam information, seek out this information from this eHow website: http://www.ehow.com/about_4673650_history-polyurethane-foam.html
How do you made computer mouse ball?
The ball inside older mice - was made of a solid steel ball coated in a thick layer of rubber.
