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
Answers
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).

What is the rice bag's gravitational potential energy?
Answers
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

Answers
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.

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.

What happens to the current in a circuit if a 100

Answers
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.

The voltage between two points in a circuit is 4.2 V. If the resistance between

A. 0.058 A
B. 76.2 A
O C. 17.1 A
O D. 302 A
Answers
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:

an object increases its velocity from 22 m/s to 36 m/s in 5s.what is the acceleration of the object
Answers
Answer:
2.8 m/s²
Explanation:
v=v0+at <=> 36 = 22 + a×5 <=> 5a = 36-22 <=> 5a = 14 <=> a = 14/5 <=>
<=> a = 2.8 m/s²
a = v - u by t
Given - u = 22 m/s
v = 36 m/s
t = 5 sec
Solution -
a = v - u by t
a = 36 - 22 by 5
a = 14 by 5
a = 2.8 m/s^2
.:. The acceleration is 2.8 m/s^2.

O Apuddle of water is exposed to the sun and evaporates.
O A tree in a forest grows naturally over 10 years.
Answers
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.
