Calculate the mass that a person can lift on the moon if they can lift a mass of 50kg on the earth. The value of g on the surface of the Earth is 9.8m/s² and that of the moon is 6 times less. Which of the following relations would be correct according to Pascal's law? Identify the characteristics of the image of the object XY kept in front of the lens as shown in the given figure. Which of the following is proved by Hubble's law? Which one is a double displacement reaction from the following?
Understand the Problem
The questions are asking various scientific concepts, such as calculating mass based on gravitational differences, Pascal's law in hydraulics, properties of lens images, and Hubble's law regarding the universe. Each part requires an understanding of physics principles.
Answer
300 kg; P1 > P2; Virtual, inverted, diminished; Universe expanding; XY + AB → XB + AY.
The mass a person can lift on the Moon if they can lift 50 kg on Earth is approximately 300 kg. According to Pascal's law, relation (i) P1 > P2 would be correct. The image of the object XY kept in front of the lens is (iii) Virtual, inverted and diminished. Hubble's law proves that (ii) the Universe is expanding. The double displacement reaction is (iv) XY + AB → XB + AY.

The mass a person can lift on the Moon if they can lift 50 kg on Earth is approximately 300 kg. According to Pascal's law, relation (i) P1 > P2 would be correct. The image of the object XY kept in front of the lens is (iii) Virtual, inverted and diminished. Hubble's law proves that (ii) the Universe is expanding. The double displacement reaction is (iv) XY + AB → XB + AY.
More Information
On the Moon, the gravitational pull is about 1/6th of that on Earth, allowing a person to lift about six times more mass. Hubble's law is a key piece of evidence for the expanding universe, and a double displacement reaction involves exchanging components between two compounds.
Tips
Ensure to multiply by the correct factor when converting gravitational effects from Earth to the Moon.
