Speed = Distance / Time
In this case, the distance covered is 100 meters, and the time taken is 60 seconds.
Speed = 100 meters / 60 seconds = 1.67 meters per second
So, the speed of the swimmer is approximately 1.67 meters per second.

imaginative and original
unreasonable and outdated
Answers
Answer:
The correct answer will be option-imaginative and original.
Explanation:
The study of any natural phenomenon is based on the methods developed by humans. These methods are known as scientific methods as they approach the explanation in a systematic way.
The quest to understand the astronomical perspective-universe, planets and the planetary motions began around 2500 years ago which persists even today.
To understand the solar system researcher has to be a keen observer, imaginative and truthful to the evidence and data recorded. The logical imagination is essential to study the solar system as one is not able to see the far objects. This practicality allowed the researcher to think and rethink over the laws governing the systems.
Thus, option-imaginative and original is the correct answer.
How many electrons pass the point in this time?
Answers
A = 0.12 C/s ... [b/c 1 A = 1 C/s]
t = 25 s
I = Q/t
Q = It
Q = 0.12 * 25 = 3 C
so 3C of charge passes the point during the
25 s interval

The correct answer is
b. False
It's actually the opposite: only a very small part of the electromagnetic spectrum is visible to human eye.
The electromagnetic spectrum consists of a huge range of wavelengths, spanning from gamma rays (with very short wavelength, at the order of 1 pm) to radio waves (with very long wavelength, at the order of kilometers). The only portion of this spectrum visible to the human eye is the "visible light", which has wavelengths between 400 and 700 nanometers approximately.
The statement is False. All the electromagnetic radiations are not visible to the human eyes.
Explanation:
The waves are defined as the disturbance produced in the medium particles. The wave is basically the physical phenomena that occurs in a medium and it is characterized by the amplitude, wavelength and the frequency of oscillating particles.
The waves are basically characterized as the transverse and the longitudinal based on the direction of oscillation. The transverse waves are the one in which the direction of oscillation is perpendicular to the propagation whereas in longitudinal waves, the direction of oscillation is along the motion of the wave.
The electromagnetic waves are the transverse waves that are formed by the perpendicular magnetic and electric field present in the medium. The complete electromagnetic spectrum is not considered to be in the visible range for the human eye. Only a small part lying in the wavelength of .
Thus, The statement is False. All the electromagnetic radiations are not visible to the human eyes.

Rover has celebrated his first landing anniversary yesterday (Martian year, that is 687 Earth days).
Curiosity managed to find traces of water on Mars, so it's possible that there used to be some life on Mars.
Since landing Curiosity moved only about 5 miles form the landing site (it suffered wheel damage).
