Answer:
True
Explanation:
So, if your mass on Earth is 45 kg on Earth, your mass will also be 45 kg on the moon. The reason behind this is because the amount of matter you're made of doesn't change if you're on the moon or on the Earth. The weight of an astronaut and his space suit on the Moon is only 250 N.
False. The weight of an astronaut plus her space suit on the moon is not only 255 N. The weight of an object on the moon is about one-sixth of its weight on Earth.
False. The weight of an astronaut plus her space suit on the moon is not only 255 N. The weight of an object is determined by the force of gravity acting on it. The moon's gravity is about one-sixth that of Earth's, so the weight of an object on the moon is about one-sixth of its weight on Earth. If the weight of an astronaut plus her space suit on Earth is known to be 255 N, then her weight on the moon would be approximately 42.5 N.

Answer:
pressure=force/area
Explanation:
pressure equal to force divided by area,the area is how far the object sunk into the ground
Answer:
B. Sun was the center of the solar system.
B. The field gets weaker.
C. The field changes direction.
D. The field disappears completely.
Answer: The correct answer is option (B).
Explanation:
The current carrying wire produces the magnetic field around it. More the current in the wire, stronger will be the magnetic strength around the wire. The magnetic field is stronger near this wire.
The direction of the magnetic field depends on the direction of the current.
In the given problem, Linus builds an electrical circuit with a battery and with wires that carry the current.The strength of the magnetic field depends on the amount of current flowing in the wire. As the battery weakens, the current also weakens.
Therefore, the magnetic field around the wires is weaker.
The magnetic field getting weaker is the correct answer when Linus builds an electrical circuit with a battery and with wires that carry the current. The correct answer is (B).
The strength of the magnetic field around the wires is directly proportional to the current flowing through the wires. As the battery weakens and the current decreases, the magnetic field strength around the wires also decreases.
Conversely, if the current increases, the magnetic field strength increases. This relationship is described by Ampere's law and the right-hand rule, which state that the magnetic field is directly proportional to the current.
Therefore, The correct answer is (B). The magnetic field getting weaker is the correct answer.
