We are given with a force in the middle of a rope measuring 10 m and an angle of sagging of 10 degrees from the horizontal. The tension of the rope is equal to the hypotenuse of the right triangle.
sin 10 = 50 kg * 9.8 m/s2 / T
Tension = 2821. 80 N
Answer:
The magnitude of the resultant is approximately 5.391 units.
Explanation:
We notice that vectors have the following characteristics: A magnitude and direction. That is:
Where:
- Magnitude, dimensionless.
- Direction, measured in radians.
This expression can be rearranged as:
Where:
If we know a set of vectors of the form , the resultant vector () is the vectorial sum of every vector in the set:
If we know that , , and , the resultant vector is:
And lastly, we obtain the magnitude of the resultant by Pythagoras' Theorem:
The magnitude of the resultant is approximately 5.391 units.
Explanation:
Given that,
Mass of the block, m = 5 kg
Spring constant, k = 2000 N/m
The block is pulled down 5.0 cm from the equilibrium position and given an initial velocity of 1.0 m/s back towards equilibrium.
(a) The angular frequency is given by :
Since, , f is frequency
(b) The velocity of particle executing SHM is given by :
x is displacement from equilibrium position
(c) The total mechanical energy of the motion in SHM is given by :
Hence, this is the required solution.

Answer:
Wavelenght of light in the range of 470nm is that of blue colourand Allura red absorbs this blue light and reflects the red light
Then we can say Allura red absorbs all light colours but reflect red
