Answer:
Centre of gravity is a theoretical point in the body where the total weight of the body is thought to be concentrated. In a uniform gravitational field, the centre of gravity is identical to the centre of mass. Yet, the two points do not always coincide.
Answer:
The baseball was falling during 1.733 seconds.
Explanation:
The baseball experimented a free fall, which is a particular case of uniformly accelerated motion, in which object is accelerated by gravity. In this case, we need to determine the time spent by the ball before hitting the ground (
), measured in seconds, which is determined by the following kinematic formula:
(1)
Where:
, 
- Initial and final speeds of the baseball, measured in meters per second.
- Gravitational acceleration, measured in meters per square second.
If we know that 
, 
and 
, then the time spent by the baseball is:
The baseball was falling during 1.733 seconds.
Answer:
Hey, how you doing.
I think (warning I said think not to know!) that it is A because of the following:
Eruptions can be predicted if you have a good history of their activity. you also need to have lots of equipment constantly monitoring. Tsunamis can't really be predicted because earthquakes can't (that's why B is wrong). But however, if there is a giant asteroid impact you can predict that it will cuase i giant tsunamis.
A is the only one with 1 correct answer so I would go with it.
