Answer:
Magnets strongly attract materials which already themselves have magnetic domains. They do not significantly attract many metals like gold, aluminum, silver, and even some types of high-chromium stainless-steel, which lack such domains. In fact, pure gold is slightly repelled.
Explanation:
Answer:
The state of being free from the effects of gravity.
Explanation:
1. Mass of an object
2. Distance between the objects
The answer is false. The speed of the astronaut cancels out the force of gravity, causing a 'stationary freefall'. While under these effects, it is not required for an astronaut to 'strengthen' his body.
The speed of sound on planet is 210 m/s.

What is Oscillation?</h3>
Oscillation is the repeating or periodic change of a quantity around a central value or between two or more states, often in time. Alternating current and a swinging pendulum are two common examples of oscillation.
There are 3 main types of Oscillation –
- Free
- damped
- forced oscillation
f = frequency = 600 Hz
lambda = wavelength = 35 cm = 0.35 m
Now,
V = speed = f × lambda = 210 m/s
Hence, speed of sound on planet is 210 m/s.
