Conduction is slower in liquids and gases.
Liquids it is convection which transmits more heat.. quicker...
Materials which are good conductors of thermal energy are called thermal conductors.
metals are good thermal conductors.
Answer:
I'm not sure..but please refer to your teacher later.
Answer: Based on Newton's First law of motion (where inertia is involved), smooth ice increases the forceused to accelerate the hockey puck.
Explanation;
- smooth ice reduces the resistances between the surface of the figure skates and the ice itself.
- based on inertia theory ; the heavier the weight, the larger the inertia.. which explains it takes alot of force to move a heavier object than the lighter ones.. it also hard to *stop* the motion of heavier objects than the lighter ones.
- now let's look at the design of the player shoe itself, they have a sharp blade at the bottom of the figure stakes.. which takes us to the law of the force.. the smaller the surface area, the more forces acting on it. So, players force (weight, F= mg) acts on the tip of the blade and on the ice
- high inertia (run fast) and high force (attack opponent and pass puck) enables them to perform well in playing hockey
- Thus if there's no resistance and the inertia of the player is high then they could run and pass the puck quickly
Answer: Waning
Explanation: Not much explanation for this
Answer:
This is because the force of gravity is much less on the moon than on the earth, therefore the person wont be pulled down much and will jump higher
Answer:
An X-ray is used to take pictures of your bones. The waves that are used are known as radiation waves.
