4. Two objects were lifted by a machine. One object had a mass of 2 kilograms, and was lifted a t a speed of 2 m/sec. The other had a mass of 4 kilograms and was lifted at a rate of 3 m/sec.
Question a. Which object had more kinetic energy while it was being lifted?
Question b. Which object had more potential energy when it was lifted to a distance of 10 meters? Show your calculation.
Explanation:
a) Case1, by the formula, ke=½mv².
m=2kg, v=2m/s
ke = ½×2×2² = 4J
Case2, by the formula, ke=½mv².
m=4kg, v=3m/s
ke = ½×4×3² = 18J
therefore, the second object has more kinetic energy.
b) Case1, by the formula, pe = mgh
m=2kg, g=9.8m/s²(not given)(can consider 10m/s² when given), h= 10m
Pe1(write 1 in subscript) = 2×9.8×10= 196J.
Case2, by the formula, pe = mgh
m=4kg, g=9.8m/s²(not given)(can consider 10m/s² when given), h= 10m
Pe2(write 2 in subscript) = 4×9.8×10= 392J.
so, the object 2 has more potential energy.
hope this helps you.

The use of biological processes to protect and repair the environment from negative human impacts is part of a growing area of biological applications called .
Bioremediation is that process which use the biological organisms to protect and repair the environment.
Bioremediation refers to the use of biological agents or processes in order to protect and repair the environment from negative human impacts. This phenomenon depends on stimulating the growth of specific type of microbes that utilize contaminants such as oil, solvents and pesticides as a sources of food and energy.
These microbes has the ability to use these harmful substances as a food and convert these contaminants into water as well as harmless gases like carbon dioxide so we can conclude that bioremediation is that process which use the biological organisms to protect and repair the environment.

Black hair (b) is dominant over brown hair (b) in guinea pigs. What is the genotype of a brown guinea pig?.
Answer:
the genotype of the brown guinea pig would be 'bb'
Explanation:
if it had black hair the possible genotypes would be 'Bb' or 'BB' because any genotype with a capital letter is dominant and brown hair is a recessive trait I'm assuming considering the question says "over"
10. Which of the following statements about the leading strand is true?
A. It is synthesized discontinuously and uses 1 RNA primer.
B. It is synthesized discontinuously and uses multiple RNA primers.
C. It is synthesized continuously and uses multiple RNA primers.
D. It is synthesized continuously and uses 1 RNA primer.
The statement 'the leading strand is synthesized continuously and uses 1 RNA primer' is TRUE. It is replicated in the 3' – 5' direction.
The leading strand refers to the DNA template strand that is synthesized in the 3' – 5' direction during DNA replication.
The 3' – 5' direction that occurs during DNA replication is the direction of the replication fork.
RNA primers are short RNA sequences used for the initiation of the synthesis of DNA (DNA replication) both in the leading DNA strand and the lagging DNA strand.

C- Cell membrane
D- Golgi bodies
E- Smooth and rough endoplasmic reticulum
F- Cell wall
Explanation:
This is a structure of a plant cell which unlike animal cell has a cell wall as well as plasma membrane. It also contains large vacuoles present in the center of the cell. The green color of the plants is due to the presence of chlorophyll which is present in an organelles called chloroplast.
Organelles which are labelled in the cell are
A:Cell membrane
B:Vacuole
C:Nucleus
D:Cytoplasm
E:Chloroplast
F:Cell wall
The given figure represents a plant cell. So, the correct option is C.
What is Plant cell?Plant cells are defined as eukaryotic cells that contain a true nucleus as well as specialized structures known as organelles that perform certain specialized functions. Plant and animal cells both contain a nucleus with similar organelles but plant cells differ due to the presence of a cell wall outside the cell membrane.
In the given figure, labelled organelles function are as follows:
Vacuole stores food, extra water, and waste while cell membrane permits selective passage of things into and out of the cell. The cell's nucleus serves as the activity's control centre, while the cytoplasm is the fluid that gives the cell its jelly-like consistency. Chloroplasts contain a substance called chlorophyll that is a green pigment that aids in photosynthesis. The cell wall of a plant gives it form, stiffness, strength, and protection.
Thus, the given figure represents a plant cell. So, the correct option is C.

what is the dominant impact that humans have on alpine glaciers?
The researchers estimate that between 1990 and 2010, some 69 percent of the mass lost by the world's alpine glaciers can be traced to human influence – basically global warming. This 2013 file photo shows the Mendenhall Glaicer where it spills over the mountains above Mendenhall Lake in Juneau, Alaska.
Answer:
Human activity is playing an increasing role in the melting of glaciers, Austrian and Canadian scientists have found. One of the most disruptive effects of climate change, glacier retreat leads to rising sea levels, landslides and unpredictable availability of water downstream.
