What are the first two steps for finding the magnitude of the resultant vector?

Physics
1 answer:
Marina86 [1]3 years ago
8 0

Answer:

In the analytical method,

  1. Resolve the vectors into the perpendicular components of the Cartesian coordinates.
  2. Calculate the magnitude of the resultant vector using the Pythagoras theorem.

Explanation:

  • There are two methods to find the magnitude of the resultant vector.
  • One is the geometrical method and the other one is the analytical method.
  • In the geometrical method, all the vectors are connected the head to tail with the appropriate magnitude and the resultant vector is obtained by joining the initial point and the final point by a vector in the reverse direction. The magnitude of the resultant vector is given by the length of the line.
  • In the analytical method, all the vectors are resolved into the perpendicular components.
  • Using Pythagoras theorem, the magnitude of the resultant vector can be obtained
  • If A and B are the two vectors forming an angle ∅ between them, then the magnitude of the resultant vector is given by the formula

                            R=\sqrt{A^{2}+B^{2}+2ABcos\phi}

Why do sex cells contain only half the number of chromosomes needed for offspring? Explain
Bogdan [553]

Answer:

None, egg cells don't have chromosomes. No, sex cells do have chromosomes. Meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes–one homolog of each pair. This is the haploid number.

Explain how the meanings of the terms biotic factor and abiotic factor differ ?
Stells [14]
Hi There!

Biotic factors are all the living things in an ecosystem, and abiotic factors are all of the non-living things in an ecosystem. So, they differ because they both mean opposite things.

Hope This Helps :)

The length of vector A is 93.8 meters and the length of Ay is 38.4 meters, then the length of A, must be
vaieri [72.5K]

Answer:

85.556metres

Explanation:

Using pythagorean theorem

C²=A²+B²

we have c as the hypotenuse vector A thus:

93.8²=A²+38.4²

93.8²-38.4²=A²

8794.44-1474.56=A²

7319.88=A²

A=85.556

gAn optical engineer needs to ensure that the bright fringes from a double-slit are 15.7 mm apart on a detector that is from the
igomit [66]

Answer:

d = 68.5 x 10⁻⁶ m = 68.5 μm

Explanation:

The complete question is as follows:

An optical engineer needs to ensure that the bright fringes from a double-slit are 15.7 mm apart on a detector that is  1.70m from the slits. If the slits are illuminated with coherent light of wavelength 633 nm, how far apart should the slits be?

The answer can be given by using the formula derived from Young's Double Slit Experiment:

y = \frac{\lambda L}{d}\\\\d  =\frac{\lambda L}{y}\\\\

where,

d = slit separation = ?

λ = wavelength = 633 nm = 6.33 x 10⁻⁷ m

L = distance from screen (detector) = 1.7 m

y = distance between bright fringes = 15.7 mm = 0.0157 m

Therefore,

d = \frac{(6.33\ x\ 10^{-7}\ m)(1.7\ m)}{0.0157\ m}\\\\

<u>d = 68.5 x 10⁻⁶ m = 68.5 μm</u>
