Is the white dwarf a large star that is relatively cool?
No it is a small star (about the size of Earth) that is VERY dense and quite hot (although it is not producing new energy).
Does a greater buoyant act on a large object or a small object?
Larger object.
A large object that orbits a star is a?
Planet.
The jovian planets contain a large percentage of the gases?
Hydrogen and Helium
Why do tornadoes vary in size?
There are various factors that are not fully understood. Part of it has to do with how much energy a storm can put into producing a tornado, as it takes more energy to move a larger amount of air and large tornadoes tend to be stronger. This depends both on how strong the thunderstorm is and how it is organized (i.e. where energy goes and in what forms). A well organized supercell thunderstorm with a lot of energy can produce very large violent tornadoes. Additionally, a key part of tornado formation occurs when a larger circulation, called a mesocyclone , tightens and intensifies. A mesocyclone that is not tightened as much may result in a large but not particularly strong tornado.
What a large energy producing object in space that is made of gases undergoing nuclear reactions?
star
What is large energy producing object in space that is made of gases undergoing nuclear reactions?
star
What are some advantages of producing energy through fission?
Amount of energy produced is very large. This energy can be utilised.
Why does a large object absorb thermal energy faster than a smaller object?
A greater surface area allows for greater energy transfer.
In the mitochondria the smaller molecules reacts producing what?
carbon dioxide, water and large amounts of energy
Can an object have large voltage but a very low potential energy. Why?
Yes.
Which of the following is an example of nuclear fission?
A large radioactive atom breaks into smaller atoms, producing nuclear energy.
Which object forms by the contraction of a large sphere of gases causing the nuclear fusion of lighter elements into heavier element?
A star
Which object forms by the contraction of a large sphere of gases causing the nuclear fusion of lighter elements into heavier elements?
A star
Which has more kinetic energy- A small object or a large object moving at the speed of 25 mph?
You don't say what speed the small object has. If both have the same speed then the heavier one will have more kinetic energy.
Which object forms the contraction of a large sphere of gases causing the nuclear fusion of lighter elements into heavier elements?
molecular cloud
Can an object have large voltage but a very low potential energy and why?
Yes. The potential energy in this case is the product of the voltage and the charge.
