You have a plastic box that is 15cm wide x 20cm long x 10cm deep, and it weighs 30 grams. Its volume is 3000cm3, the area that will contact the water is 300cm2, and its density is .01g/cm3.
An object will displace water until the weight of water displaced is equal to the weight of the object. Divide the mass by the surface area, and we learn the box will sink into the water one millimeter.
Now add six 60g tennis balls to it. The total weight is now 390g - thirteen times the mass of the empty box. Divide the mass by the surface area, and the box will sink into the water 13mm.
Both tennis balls will reach the ground at the same time because acceleration due to gravity is constant for all objects regardless of their mass. The only factors that would affect their falling speed would be air resistance, but for a tennis ball and a lead-filled one, the difference in air resistance is negligible.
A tennis ball typically bounces the highest due to its low mass and high elasticity. The rubber material and air-filled structure of a tennis ball allow it to rebound quickly and with more energy compared to other types of balls.
A ball is a round object used in various games such as soccer, basketball, and tennis. It is typically made of rubber, leather, or plastic and is used for throwing, kicking, or hitting during gameplay.
A tennis ball is made of materials that are more elastic than a basketball, allowing it to deform and rebound quicker upon impact, resulting in a higher bounce. Additionally, the size and weight difference between a tennis ball and a basketball also contribute to the tennis ball bouncing higher.
A tennis ball has more mass than a styrofoam ball. Tennis balls are typically made of rubber and have a greater density compared to styrofoam, which is a lightweight material.
IT'S IN THE BOOK- PAGE182 NO.11 :p
yep
Rubber.
some form of plastic
cylinder?
A tennis ball is basicaly a ball filled with air through a valve. I don't kanow too much about it, I have to admit.
Explain why it would cost Andre Agassi more to leave the professional tennis tour and open a tennis shop than it would for the coach of a university tennis team to do so.
no, it will burn. it will only explode if it has been made into a "tennis ball bomb" (filled with tips of matches)
No they are made of rubber and plastic.
The official rules of table tennis state that the ball shall be:spherical, with a diameter of 40mm andweigh 2.7g andbe made of celluloid or similar plastics material andbe white or orange, and matt
it is thin layered plastic ball of radius1.3 c.m
celluloid. Plastic basically.
