When gas hydrates are brought to the surface, they evaporate quickly. This would be the biggest, current disadvantage to using gas hydrates as a form of energy.
Answer:
a. Zombie
Explanation:
Zombies- A cracker — a computer hacker who intends mischief or harm — secretly infiltrates an unsuspecting victim’s computer and uses it to conduct illegal activities. The user generally remains unaware that his computer has been taken over — he can still use it, though it might slow down considerably. As his computer begins to either send out massive amounts of spam or attack Web pages, he becomes the focal point for any investigations involving his computer’s suspicious activities. In one case of zombies it was found that over 1.5 million computers were affected in an attack.
Answer:
Upright and smaller than the object
Explanation:
Diverging lens as the name suggests that the rays diverge after the refraction and do not meet in reality. A concave lens is called diverging lens. When there is refraction of light through a concave lens then the light bends away from the principal axis and hence never meet in reality but on tracing the rays backwards the rays appear to meet leading to the formation of a virtual image, which is erect and smaller than the object for an object placed at the focus of the lens.
Similar image is formed for any case when the object is between optical center and infinity.
If a football player has more mass, they will also have more <u>momentum</u>. This is because mass is directly proportional to momentum.
Every particle of mass is attracted to every other particle of mass. The magnitude of the force between two objects is proportional to the product of their masses, and inversely proportional to the square of the distance between them. The direction of the force is along the line between their centers.
(NOTE: Newton's 3rd law of motion tells us that gravitational forces always come in pairs. Between two objects, there are two forces ... one in each direction. Their strengths are equal ... Your weight on Earth is exactly equal to the Earth's weight on YOU.)
