A rotating satellite has the same angular velocity as the earth. If the satellite is 5x10^7 m from the center of the earth, what is its tangential velocity
Answers
The angular velocity of the earth is
The satellite tangential velocity is the distance from the earth times the angular velocity, which is
For meters per second, we divide by the number of seconds in an hour, which is 3600:
Final answer:
The tangential velocity of a satellite, with the same angular velocity as the Earth and 5x10^7 m distance from Earth's center, is calculated to be approximately 3650 m/s.
Explanation:
The tangential velocity of a satellite is given by the formula v = rω, where 'v' is the tangential velocity, 'r' is the radius (distance from the center of the Earth to the satellite), and 'ω' is the angular velocity. The referenced satellite's angular velocity is the same as that of the Earth, which is approximately 7.292 x 10^-5 rad/s. Given r = 5x10^7 m (the satellite's distance from Earth), we input these values into the formula:
v = (5x10^7 m)(7.292 x 10^-5 rad/s)
Upon calculation, we find that the satellite's tangential velocity is approximately 3650 m/s.

- It is impossible to define the mass of an atom.
- The atom contains no particles that have a neutral charge.
Answers
Answer:
- The positive charge in an atom is concentrated in one location.
Explanation:
In Rutherford's experiment when alpha particles are projected towards the gold foil then he observed that major proportion of the alpha particles are moved out undeviating.
This shows that alpha particles which are positively charged are not repelled by other positive charge of nucleus as it is concentrated at small part of atom
because very few alpha particles are reflected back at 180 degree so he concluded that nucleus charge is concentrated at very small space
and that part is termed as nucleus.
so correct answer is
- The positive charge in an atom is concentrated in one location.
The positive charge in an atom is concentrated in one location.
Why is gravity an example of scientific law?
Answers
Because it is a basic concept that defines a constant and universal behaviour of nature, gravity is seen as an illustration of a scientific law.
Scientific laws are succinct formulations that precisely explain a natural occurrence and are the result of in-depth observation and investigation. Einstein's theory of general relativity or Newton's law of universal gravitation both use the concept of gravity to explain how mass-containing objects interact with one another in space.
It offers a mathematical framework that enables researchers to perform precise projections and estimates about celestial body motion, the behaviour of things close to the surface of the Earth, and the structure of the cosmos.
The fact that gravity is recognised as a scientific rule is a reflection of the fact that it is widely accepted and has been shown to have practical applications.

wave in medium A, the wave in medium B has
(1) half the speed
(2) twice the speed
(3) half the frequency
(4) twice the frequency
Answers
Final answer:
The situation described in the question pertains to wave propagation. Given that wave speed in a given medium is constant, and the relationship between wave speed, wavelength, and frequency, the wave in medium B, which has double the wavelength of the wave in medium A, would have half the frequency of the wave in medium A.
Explanation:
This question is about wave propagation between two different mediums, labeled 'A' and 'B'. The fundamental principle involved here is the dependence of wave speed on the medium through which it travels. However, it's necessary to recognize that wave speed also depends on wavelength and frequency. This relationship is encapsulated by the formula v = fλ, where v is wave speed, f is frequency, and λ is wavelength.
From the problem statement, we understand that the wavelength doubles when going from medium A to medium B. We are then asked to deduce the corresponding change in wave speed or frequency. If the wavelength doubles and the wave speed remains the same, the only possible adjustment is for the frequency to halve. So, the wave in medium B, compared to the wave in medium A, would have half the frequency (3). This is because wave speed in a given medium is constant and as per the formula, if wavelength increases, frequency must decrease.

Answer:
True
Explanation:
In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).
