Answer:
C. Seed C germinates more with more water.
Explanation:
In this experiment, the seed (seed C) was subjected to certain conditions and the result is what has been presented for us to make an inference.
We observe the following from the information given us:
I. the same seeds were used for the experiment
II. the same heat medium of 24 °C was used for all the seeds
III. different daily amount of water was supplied the seeds - 90 ml, 50 ml and 10 ml
From the experiment, we have this result:
the seed that was watered with 10 ml daily did not sprout anything, the seed that was watered with 50 ml daily yielded 12 sprouts while the seed that was watered with 90 ml daily yielded 16 sprouts
When we consider the amount of water given the seed & the produce of the seed, it is safe to conclude that with increase in daily water, there is increase in the number of sprouts by the seed

<u>Hence, C. Seed C germinates more with more water is the correct answer </u>
Answer:
- The gravity does a work of - 117.6 Joules.
- The tension does not do work as the force is perpendicular to the direction of motion at any point in the trajectory.
Explanation:
The work done by the gravity simply is the difference in gravitational potential energy multiplied by -1:

where m is the mass of the ball, g is the acceleration due to gravity,
is the final height and
is the initial height.
So, if the radius is 2.00 m, then the difference of height will be 4 meters:



As the tension is perpendicular to the velocity of the ball, the force is always perpendicular to the direction of motion. So, the differential of work will be:

Answer:
From the negative to the positive cable.
Explanation:
The electrons have negative charge, which means that the negative terminal of the battery will suply the electrons, thus they are present in excess on the negative cable and will jump from it to the positive cable. This current direction is called real current.
If you and the source of sound are moving apart, then the pitch (frequency) <em>you hear</em> is <em>lower</em> than the pitch (frequency) that's actually leaving the source.
It doesn't matter whether you or the source is the one moving, only that the distance between you is increasing.
