Under the cost-sharing agreement, the sub will have to pay the parent $40m, as the subâs fraction of benefits from the patent are 40% = 2/5ths of the companyâs total benefits from the patent and the parentâs total cost of developing the patent was $100m.
An asteroid is a large, irregularly shaped object in space that orbits our Sun. If one of these giant rocks ends up on a collision course with Earth, we are in for big trouble. An asteroid is like a comet. However, while comets are mostly made of ice, asteroids are made up of rock or even metal. This makes them dangerous because they can cause a lot of damage if they collide with a planet.
Asteroids can be made from rock, ice, iron, or a mixture of all three. An asteroid of a certain size that is made of iron will have more mass than one that is made of rock or ice. This is important when calculating ways that we can move an asteroid away from the Earth: the greater the mass, the more time and more energy it takes to move it.
