What is the resultant displacement of the two vectors below

NeX [460]

Answer:

The resultant displacement is 5.8 cm, 31° South of the West axis ⇒ 4th

answer

Explanation:

<u><em>A resultant vector</em></u> is the combination of two or more single vectors

If the two vectors are perpendicular, then

<em><u>The magnitude</u></em> of the resultant vector = $\sqrt{x^{2}+y^{2}}$ ,where

x represents the horizontal vector and y represents the vertical vector

<em><u>The direction</u></em> of the resultant vector is $tan^{-1}\alpha$ , where α

is the angle between the horizontal vector and the resultant vector

Vector 1 is 5 cm due to West-axis

Vector 2 is 3 cm due to South-axis

We need to find the resultant displacement of them

The West and South are perpendicular

The West is the horizontal vector and South is the vertical vector

The magnitude of the resultant displacement s is:

$s=\sqrt{(5)^{2}+(3)^{2}}$

$s=\sqrt{25+9}$

$s=\sqrt{34}=5.8$

The direction of the resultant displacement s is:

$tan^{-1}\frac{3}{5}=31$ ° south of the west (between the west and

the resultant displacement)

<em>The resultant displacement is 5.8 cm, 31° South of the West axis</em>

The displacement at any given time of an object is x = 6 sin 98t , where the symbols have their usual meanings. i). Proof that t

Fofino [41]

A simple harmonic motion is defined by the amplitude and angular frequency of the oscillation, which are represented in the given function as 6 units and 98 rad/s respectively.

<h3>General wave equation for simple harmonic motion</h3>

y = A sinωt

where;

A is amplitude of the motion
ω is angular frequency

<h3>Amplitude of the oscillation</h3>

A = 6 units

<h3>Angular frequency of the wave</h3>

ω = 98 rad/s

A simple harmonic motion is defined by the amplitude and angular frequency of the oscillation. Thus, the wave is executing simple harmonic motion.

What is the role of neutrons in the nucleus.

Serjik [45]

Answer:

<em><u>To be neutral</u></em>

Explanation:

Neutrons are electrically neutral but contribute to the mass of a nucleus to nearly the same extent as the protons. Neutrons can explain the phenomenon of isotopes (same atomic number with different atomic mass). The main role of neutrons is to reduce electrostatic repulsion inside the nucleus.

Four factors that affect the rate heat transfers through solids

MA_775_DIABLO [31]

Answer:

The amount of heat flow is . How does heat flow through solids? Conduction is the transfer of heat through solids. Factors that affect rate of heat flow include the conductivity of the material, temperature difference across the material, thickness of the material, and area of the material.
