The gravity of an object depends on its __________ .
-
Size
-
Mass
-
Speed
-
Acceleration
Correct Answer
A. MassExplanation
The gravity of an object depends on its mass because mass is a measure of the amount of matter in an object. The more mass an object has, the stronger its gravitational pull. This is why larger objects, such as planets or stars, have stronger gravitational forces than smaller objects. Speed and acceleration do not directly affect gravity, while size is not a precise measure of an object's mass.Rate this question:

Motion is another great discovery in Physics. Who discovered the three laws of motion and explained how gravity works?
-
Isaac Newton
-
Galileo Galilei
-
Albert Einstein
-
Thomas Edison
Correct Answer
A. Isaac NewtonExplanation
Isaac Newton is the correct answer because he is the scientist who discovered the three laws of motion and explained how gravity works. Newton's laws of motion describe the relationship between the motion of an object and the forces acting upon it. His law of universal gravitation explains how every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.Rate this question:
-
- 12.
Is it true that gravity helps the Earth to stay in orbit around the Sun?
-
True
-
False
Correct Answer
A. TrueExplanation
Gravity is the force of attraction between two objects with mass. In the case of the Earth and the Sun, gravity is what keeps the Earth in orbit around the Sun. The gravitational pull of the Sun keeps the Earth moving in a curved path, preventing it from flying off into space. Without gravity, the Earth would not be able to maintain its orbit around the Sun. Therefore, it is true that gravity helps the Earth to stay in orbit around the Sun.Rate this question:

Without this substance you will not live even for ten minutes.
-
Oxygen
-
Water
-
Nitrogen
-
Salt
Correct Answer
A. OxygenExplanation
Oxygen is essential for sustaining life as it is required for the process of respiration. Without oxygen, the body cannot produce energy, leading to organ failure and ultimately death. While water, nitrogen, and salt are also important for the body, they do not have the same immediate life-sustaining function as oxygen.Rate this question:

What inert gas is used to fill airships?
-
Helium
-
Argon
-
Neon
-
Krypton
Correct Answer
A. HeliumExplanation
Helium is used to fill airships because it is an inert gas, meaning it does not react with other substances. This makes it safe for use in airships as it does not pose a risk of combustion or explosion. Additionally, helium is lighter than air, which allows the airship to float and be controlled easily.Rate this question:

Once Albert Einstein gave a lecture at the University of Zurich. Students presented at his lecture occupied 5/7 of all the seats. There were 540 people present. How many seats were there in the auditorium?
-
350
-
756
-
400
-
596
Correct Answer
A. 756Explanation
If 5/7 of the seats were occupied by the students, then the remaining 2/7 of the seats were empty. We can set up a proportion to find the total number of seats in the auditorium. Let x represent the total number of seats. We can write the equation 5/7 = 540/x. Cross multiplying, we get 5x = 3780. Dividing both sides by 5, we find that x = 756. Therefore, there were 756 seats in the auditorium.Rate this question:

Which of these substances dissolves (растворяется) in water?
-
Flour
-
Salt
-
Sand
-
Stones
Correct Answer
A. SaltExplanation
Salt dissolves in water because it is an ionic compound made up of positively charged sodium ions and negatively charged chloride ions. When salt is added to water, the water molecules surround the ions and pull them away from each other, breaking the ionic bonds and allowing the salt to dissolve. This process is known as hydration. Flour, sand, and stones are not soluble in water and do not dissolve.Rate this question:

Einstein's first laboratory in Bern was very small - 8 m long and 3 m wide. What was the perimeter of the laboratory?
-
11 m
-
19 m
-
22 m
-
24 m
Correct Answer
A. 22 mExplanation
The perimeter of a rectangle is calculated by adding up the lengths of all its sides. In this case, the length of the laboratory is given as 8 m and the width is given as 3 m. To find the perimeter, we add twice the length to twice the width. So, 2(8 m) + 2(3 m) = 16 m + 6 m = 22 m. Therefore, the perimeter of the laboratory is 22 m.Rate this question:

Little Albert Einstein liked to play with cards arranging them in different patterns. If he has 23 cards at the moment and wants to arrange them in 6 rows, what is the smallest number of additional cards he should use in order to be able to arrange the cards this way?
-
1
-
2
-
3
-
4
Correct Answer
A. 1Explanation
In order to arrange the cards in 6 rows, each row should have the same number of cards. Since 23 is not divisible by 6, Albert needs to add an additional card to the existing 23 cards to make them divisible by 6. This way, he will have 24 cards and can arrange them evenly in 6 rows of 4 cards each. Therefore, the smallest number of additional cards he should use is 1.Rate this question:

-
8°С
-
10°С
Correct Answer
A. 11°СExplanation
The question asks how many degrees colder it was in New York than in Bern. The temperature in Bern is not given, so we cannot determine the exact temperature difference.

Which is an irreversible (необратимое) change?
-
Burning candle
-
Dissolving salt
-
Freezing water
-
Melting chocolate
Correct Answer
A. Burning candleExplanation
An irreversible change refers to a process that cannot be reversed or undone. When a candle burns, it undergoes a chemical reaction called combustion, where the wax reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. Once the candle has burned, it cannot be restored to its original form. Therefore, burning a candle is an example of an irreversible change.Rate this question:
