Answer: The choices?
Explanation:
malnourishment is harmful during
Answer:
People who are in good health at the beginning of a hunger strike "are usually at little risk of dying from malnutrition for at least six to eight weeks," the guidelines state. But people who are ill can die from malnutrition in as little as three weeks. Malnutrition during pregnancy can be quite harmful. Maternal malnutrition during pregnancy can affect the wellbeing and development of the baby. Malnutrition is when the baby and in this case, the mother do not receive adequate nourishment during pregnancy. It means the baby, in the mother’s womb does not get enough nutrients to grow.

A 35 kg object is on the surface of Venus. Venus has a mass of 4.87x10^24 kg and a radius of 6.05x10^6 m. What is the mass of the object on Earth?
O 35 kg
O 35N
0 343 N
O 343 kg
Answer:
35 kg
Explanation:
Given that,
Mass, [tex]m_1=35\ kg[/tex]
Mass of Venus, [tex]m_2=4.87\times 10^{24}[/tex]
Radius of Venus, [tex]r=6.05\times 10^{6}\ m[/tex]
We need to find the mass of the object on Earth.
Mass of an object is the amount of matter contained in it. It remains constant at every location. Here, the mass of the object is 35 kg on the Earth. It means its weight on Earth will remain the same i.e. 35 kg.
Hence, the correct option is (a).

The height of the shelf is 2 meters.
What is the rice bag's gravitational potential energy?
Answer:
117.6 JExplanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have

Which is the best example of decreasing entropy?
O A box of nails is left in the rain and the nails rust over time.
O A pile of dirt on a floor is cleaned up with a broom.
O Apuddle of water is exposed to the sun and evaporates.
O A tree in a forest grows naturally over 10 years.
Answer:
B. A pile of dirt on the floor is cleaned up with a broom.
Explanation:
An increasing entropy is something that is left to be, like the other answers. decreasing entropy is disrupted usually by a person or something living.
When the pile of dirt on a floor is cleaned up with a broom, the molecular weight of the dirt present on the floor will decrease resulting in a decreased entropy.
Entropy is the measure of the degree of disorderliness of a system. It entails the randomness of a system.
Entropy of a system increases with increase in temperature and molecular weight of the compound.Entropy can also increase when the pressure of the system is reduced.A decrease in entropy would mean an increase in pressure, or a decrease in molecular weight or temperature.
Thus, considering the given options, only option B will result in a decreased molecular weight. When the pile of dirt on a floor is cleaned up with a broom, the molecular weight of the dirt present on the floor will decrease resulting in a decreased entropy.

A child kicks a ball horizontally with a speed of 4.8 m/s off a deck 3.5 m off the ground. How far, in meters, from the deck does the ball land on the ground?
Answer:
2.605m
Explanation:
Using the formula for calculating Range (distance travelled in horizontal direction)
Range R = U√2H/g
U is the speed = 4.8m/s
H is the maximum height = ?
g is the acc due to gravity = 9.8m/s²
R = 3.5m
Substitute into the formula and get H
3.5 = 4.8√2H/9.8
3.5/4.8 = √2H/9.8
0.7292 = √2H/9.8
square both sides
0.7292² = 2H/9.8
2H = 0.7292² * 9.8
2H = 5.21
H = 5.21/2
H = 2.605m
Hence the height of the ball from the ground is 2.605m

each element has an atomic number state which is meant by atomic number
Answer: The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons. The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.

The person's complete trip was a 6km round trip because they traveled 3km north and then 3km south, returning to their original location.
What is trip?A trip is a journey or excursion to some destination, usually for a specific purpose. It can be as short as a day trip or as long as a round-the-world adventure. A trip typically involves travel by foot, car, railroad, boat, or airplane and often involves multiple destinations. It may also involve activities such as camping, hiking, sightseeing, and other leisure activities. Travelers usually plan trips in advance to ensure they have enough time to see and do the things they want to. Trips can also be spontaneous, with travelers deciding on the fly where to go and what to do.

The voltage between two points in a circuit is 4.2 V. If the resistance between
the points is 72, what is the current, according to Ohm's law?
A. 0.058 A
B. 76.2 A
O C. 17.1 A
O D. 302 A
Answer:
I = 0.058 [A]
Explanation:
Ohm's law is defined as voltage equal to the product of current by resistance.
[tex]V =I*R[/tex]
where:
V = voltage = 4.2 [V]
I = current [amp]
R = resistivity = 72 [ohm]
Now clearing I, we have:
[tex]I = V/R\\I = 4.2/72\\I = 0.058 [A][/tex]
Answer:
A. 0.058 A

What happens to the current in a circuit if a 100
resistor is removed and replaced by a 200resistor?
Answer:
current decrease to half
The current in a circuit if a 100 resistor is removed and replaced by a 200 resistor current decrease to half.
What is resistor?
A resistor is a passive two-terminal electrical component used in circuits to implement electrical resistance. Resistor use in electronic circuits includes lowering current flow, adjusting signal levels, dividing voltages, biasing active devices, and terminating transmission lines.
When potential is constant than current is inversely proportional to resistance if we increase the resistance current will be half.
