If a 10,000 g mass is suspended from a rope, what is the tensile force in the rope?
nadezda [96]

To solve this problem we will apply Newton's second law and the principle of balancing Forces on the rope. Newton's second law allows us to define the weight of the mass, through the function

F = ma\rightarrow F =mg

Here,

m = mass

a = g = Gravitational acceleration

Replacing we have that the weight is

W= (10kg)(9.8)

W = 98N

Since the rope is taut and does not break, the net force on the rope will be zero.

\sum F = 0

T-W = 0

T = W

T = 98N

Therefore the tensile force in the rope is 98N

Please help quick! 3 questions if you answer all I will give brainliest
Nat2105 [25]

Answer:  1.Spectroscopes breaks the light from a single material into its component colors the way a prism splits white light into a rainbow. It records this spectrum, which allows scientists to analyze the light and discover properties of the material interacting with it.  

2.Optical Telescopes The now-indispensable optical telescope instrument was pioneered by Galileo Galilei in 1609, although others had created similar tools by then

2.A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.

3.Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.Once the pressure and the temperature inside get high enough for nuclear fusion to ignite, it creates a star.
