The acceleration of gravity (on Earth) is 9.8 m/s² downward.
This means that every falling object gains 9.8 m/s more downward speed
every second that it falls.
In 5 seconds of falling, it gains (5 x 9.8 m/s) = 49 m/s of downward speed.
If it was already descending at 2.0 m/s at the beginning of the 5 sec,
then at the end of the 5 sec it would be descending at
(2 m/s + 49 m/s) = 51 m/s .
Answer: B
Baking soda has unique properties. It can be used in multiple ways, like cleaning. Productive means something produces a lot of something. Baking soda does not produce anything. Baking soda does not have distinguishable properties, other things can substitute baking soda.
Hope this answer helps you!
Asexual reproduction is a type of reproduction that only requires one parent. The offspring only have the characteristics and traits from that parents. They create “clones” if you will. This is the most common form of reproduction for single cell organisms like prokarayotes and bacteria.
Here are the advantages:
1. Rapid Populating
Asexual reproduction gives the ability to produce large quantities of of offspring. This helps to fill up niche’s quickly and prevent intruders and competition from invading.
2. No Mates Required
Finding a mate can be very difficult for organisms that are in desolate environments, like the deep ocean. Asexual reproduction takes the need to find a mate away, allowing these organisms to multiply.
3. In Case of Emergency
In dire situations, plants and organisms can keep themselves alive and produce others to help them without the help of a mate, or other reproductive source. Plants are a great example of this. If no pollinator is available to pollinate, then they can clone by asexual reproduction.
4. No True Investment
Asexual reproducers do not have to carry their offspring for a long amount of time and produce more than one at a time. This makes it a quick and inexpensive process for them in the terms of time.
Here are the disadvantages:
1. No Diversity
Since the traits of only one parent is passed on, all of the offspring are exactly identical. This causes for a very big lack of diversity among the population of these organisms.
2. Prone To Extinction
All of the same traits also means all of the same weaknesses. Parasites and other predators that have evolved to kill just one of the organisms can take out the entire population.
3. Cannot Adapt
An organism has established reactions to certain things, and all of these reactions are passed down to their offspring with asexual reproduction. This makes it impossible for them to adapt to any environment changes.
Answer:
Explanation:
Given
mass of ship =1240 kg
height=37 m
(a)Work done by Tension in cable+work done by gravity =0
Work done by gravity =change in potential energy of mass
Thus work done by tension=449.624 kJ
(b)work done by force of gravity
=-449.624 kJ
