I think it would be A: gold ring
if you were to place all of these on a bed of water, the ring would be the first to sink.
The following are four real life examples of the result of scientific investigation:
1. The development of the whole human genome.
2. The discovery of penicillin.
3. The discovery of a drug that cures tuberculosis.
4.The discovery that atoms have different energy levels and that electrons are found at each level.
All these events comes about as a result of scientific investigations.
Yes me too lol i agree :)
Answer:
S = V t - 1/2 a t^2 a here is negative due to deceleration
S = 4 * 8 - 1/2 * 64 = 0
The object just returns to its original starting point
It started out at 8 m/s which was reduced to 0 m/s after 4 sec
In 4 more seconds it was moving at -8 m/s, just the opposite of where it started
We are given a bucket with pennies. We are asked to increase the gravitational potential energy. The gravitational potential energy is the energy that is related to the position of the object and is determined by the following formula:
This means that the gravitational potential energy depends on the height and the mass. Therefore, to increase the gravitational potential energy we must increase the height of the bucket. Therefore, we need to add more books. Therefore, the right option is B.
