a vector needs to be divided into components when ?
Answer:
Calculating the magnitude of a vector is only the beginning. The magnitude function opens the door to many possibilities, the first of which is normalization. Normalizing refers to the process of making something “standard” or, well, “normal.” In the case of vectors, let’s assume for the moment that a standard vector has a length of 1. To normalize a vector, therefore, is to take a vector of any length and, keeping it pointing in the same direction, change its length to 1, turning it into what is called a unit vector.To normalize a vector, simply divide each component by its magnitude. This is pretty intuitive. Say a vector is of length 5. Well, 5 divided by 5 is 1. So, looking at our right triangle, we then need to scale the hypotenuse down by dividing by 5. In that process the sides shrink, divided by 5 as well.

What is the hydrostatic pressure at the bottom of a vessel in which water 30 cm high and gasoline 10 cm high have been poured? (density = 800)
Answer:
P = 3136 Pa
Explanation:
The formula to apply in this case is :
P= rho*g*d where;
rho = density = 800
g = acceleration due to gravity =9.8 m/s²
d= depth = 10+30 =40 cm = 0.4 m
P= hydrostatic pressure
P= 800 * 9.8 * 0.4
P = 3136 Pa

Different colors of light travel at greatly different speeds, even in the same medium.
True
False
Answer:
True
Explanation:
Different colors of light travel at greatly different speeds even in the same medium. This is what causes the dispersion of light through a prism.
In a vacuum, the speed of light is the same For other mediums, the speed of light depends on the properties of that medium. Light propagation depends on the medium it passes through because the photons of light interacts with the medium. The frequency of light remains the same in all medium but the speed and wavelength depends on the medium.Answer:Its false just took the test.

A stone is released from rest from a height of 60 m. How long does it take to hit the ground?
4.4 s
2.3 s
5.2 s
3.5 s
Answer:
3.5 s
Explanation:
Given
[tex]Initial\ Velocity (u) = 0m/s[/tex] --- because it starts from rest
[tex]Height\ (S) = 60\ m[/tex]
Required
Determine time (t) to hit the ground
This can be solved using the following motion equation
[tex]S = ut + \frac{1}{2}gt^2[/tex]
Substitute values for S and u and take g as 9.8m/s^2
[tex]60 = 0 * t + \frac{1}{2} * 9.8 * t^2[/tex]
[tex]60 = 0 + \frac{1}{2} * 9.8 * t^2[/tex]
[tex]60 = \frac{1}{2} * 9.8 * t^2[/tex]
Multiply through by 2
[tex]2 * 60 = 2 * \frac{1}{2} * 9.8 * t^2[/tex]
[tex]120 = 9.8 * t^2[/tex]
Solve for t^2
[tex]t^2 = \frac{120}{9.8}[/tex]
[tex]t^2 = 12.2448979592[/tex]
Take square roots
[tex]t = \sqrt{12.2448979592[/tex]
[tex]t = 3.49927106112[/tex]
[tex]t=3.5\ s[/tex] ---- approximated
It would take a stone released from a height of 60m, 3.5s to hit the ground.
EQUATION OF MOTION:
The time taken for a stone of height 60m to hit the ground can be calculated by using the following formula of motion:S = ut + ½at²Where;
S = distance (m)u = initial velocity (m/s)t = time a = acceleration due to gravity (9.8m/s²)Since the stone is released from rest, it would have a initial velocity of 0m/s. 60 = (0×t) + ½ × 9.8 × t²60 = 4.9t²t² = 60 ÷ 4.9t² = 12.24t = √12.24t = 3.5sTherefore, it would take a stone released from a height of 60m, 3.5s to hit the ground.Learn more at: https://brainly.com/question/13883874?referrer=searchResults

5. An electric field has a strength of 10.0 N/C at a distance of 1.00 m from an unknown charge. At
what distance from the charge does the electric field strength equal 2.50 N/C?
Answer:
The electric field strength is equal to 2.50 newtons per coulomb at a distance of 2 meters.
Explanation:
From Classic Electrostatic Theory, we find that electric field ([tex]E[/tex]), measured in newtons per coulomb, is defined by the following equation:
[tex]E = \frac{F}{q_{O}}[/tex] (1)
Where:
[tex]F[/tex] - Electrostatic force, measured in newtons.
[tex]q_{O}[/tex] - Electric charge, measured in coulombs.
In addition and supposing that phenomena occurs between particles, electrostatic force is modelled after the Coulomb's Law:
[tex]F = \frac{k\cdot q\cdot q_{O}}{r^{2}}[/tex] (2)
Where:
[tex]k[/tex] - Electromagnetic constant, measured in newton-square meters per square coulomb.
[tex]q[/tex], [tex]q_{O}[/tex] - Electric charges, measured in coulomb.
[tex]r[/tex] - Distance between particles, measured in meters.
By applying (2) in (1), we get the following definition of electric field:
[tex]E = \frac{k\cdot q}{r^{2}}[/tex] (3)
Then, we observe that electric field is inversely proportional to the square of the distance. The following relationship is therefore constructed:
[tex]\frac{E_{2}}{E_{1}} = \left(\frac{r_{1}}{r_{2}} \right)^{2}[/tex] (4)
If we know that [tex]E_{1} = 10\,\frac{N}{C}[/tex], [tex]E_{2} = 2.50\,\frac{N}{C}[/tex] and [tex]r_{1} = 1\,m[/tex], then the distance is:
[tex]\left(\frac{E_{2}}{E_{1}} \right)\cdot r_{2}^{2}= r_{1}^{2}[/tex]
[tex]r_{2}^{2}=\left(\frac{E_{1}}{E_{2}} \right)\cdot r_{1}^{2}[/tex]
[tex]r_{2} = r_{1}\cdot \sqrt{\frac{E_{1}}{E_{2}} }[/tex]
[tex]r_{2} = (1\,m)\cdot \sqrt{\frac{10\,\frac{N}{C} }{2.50\,\frac{N}{C} } }[/tex]
[tex]r_{2} = 2\,m[/tex]
The electric field strength is equal to 2.50 newtons per coulomb at a distance of 2 meters.

SONAR is an example of which type of wave behavior? Explain how it works and be sure to name the type of wave involved
Answer:
sound waves
Explanation:
SONAR (originally an acronym for Sound Navigation And Ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.
In this method, to find the depth of an ocean, a strong ultrasonic wave is sent from the ship towards the bottom of the ocean. This ultrasonic wave is received back after it is reflected from the bottom of the sea. The time interval t for travel of sound waves from the source to the receiver after reflection is noted.The distance travelled by the ultrasound ray is given by the equation: 2d=vt, where v is the velocity of sound. From this the depth d can be calculated.
Answer:
Sonar uses sound waves to 'see' in the water.
Sonar, short for Sound Navigation and Ranging, is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves.Sonar (sound navigation ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.[2] Two types of technology share the name "sonar": passive sonar is essentially listening for the sound made by vessels; active sonar is emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation,[3] and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term sonar is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extremely high (ultrasonic). The study of underwater sound is known as underwater acoustics or hydroacoustics.
The objective lens and the eyepiece of a telescope are spaced 85 cm apart. If the eyepiece is123 D what is the total magnification of the telescope?
Answer:
The magnification would be "103.55". A further explanation is given below.
Explanation:
The given values are:
Distance between lens and eyepiece,
L = 85 cm
Eyepiece is,
= 123 D
Now,
The refractive power of eye piece will be:
⇒ [tex]\frac{1}{f_e}=123D[/tex]
[tex]f_e=\frac{1}{123D}[/tex]
[tex]f_e=0.813 \ cm[/tex]
The length of the telescope will be:
⇒ [tex]L=f_0+f_e[/tex]
⇒ [tex]f_0=L-f_e[/tex]
On substituting the values, we get
⇒ [tex]=85-0.813[/tex]
⇒ [tex]=84.187 \ cm[/tex]
Now,
The magnification of the telescope will be:
⇒ [tex]M=\frac{f_0}{f_e}[/tex]
⇒ [tex]=\frac{84.187}{0.813}[/tex]
⇒ [tex]=103.55[/tex]
