Answer:

Heavy rain, extreme weather conditions, humid, water spouts, tornadoes, heavy lightening.

Explanation:

Swampy areas are a transition area formed where water and dry lands tend to meet. Swampy areas are actually forested areas with contains moist and humid weather conditions which has necessitated the wet soil around such an environment.

Florida is a very typical example of a weather that supports the creation of swampy areas due to its humid, heavy rains, water spouts,turnadoes etc and other extreme weather conditions.

Answer:

[tex]d_t=1339m[/tex]

[tex]d_r=953.98[/tex]

[tex]x=37.975 \textdegree[/tex]

Explanation:

From the question we are told that

1st distance [tex]d_1=752 m[/tex]

2nd distance [tex]d_2=587 m[/tex]

Generally the total distance [tex]d_t[/tex]covered by the man is mathematically given as

[tex]d_t =1st\ distance +2nd\ distance[/tex]

[tex]d_t=752+587\\d_t=1339m[/tex]

Generally the resultant distance traveled is mathematically given as

[tex]d_r^2=d_1^2+d_2^2[/tex]

[tex]d_r=\sqrt{752^2+587^2}[/tex]

[tex]d_r=953.98[/tex]

Generally the angle  using sine rule traveled is mathematically given as

let angle =x

[tex]\frac{sin90}{d_r} =\frac{sinx}{587}[/tex]

[tex]sinx=\frac{sin90*587}{953.98}[/tex]

[tex]x=37.975 \textdegree[/tex]

Answer:

Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. Pure ethanol freezes at -115 degrees C, while mercury freezes at -38 degrees C.

Explanation:

It is less durable because alcohol evaporates faster than mercury. It cannot measure high temperature because of a low boiling point. It wets the walls of the thermometer, which can adversely impact the accuracy of readings

Answer:

The choice that correctly identifies the volume of water in the graduated cylinder is option B i.e 35 mL

Explanation:

The complete question is

As a part of a laboratory investigation, Emily measured the volume of water in a graduated cylinder. Which of the choices correctly identifies the volume of water in the graduated cylinder? A. 38 mL B. 35 mL C. 37 mL D. 36.5 mL

The image for the question is attached herewith

Solution

The meniscus formed in this figure is a concave figure and in any concave figure the readings are taken from the bottom of the curve at eye level. In the attached image the bottom of the meniscus at the eye level is marked at 35 mL.

Hence the choice that correctly identifies the volume of water in the graduated cylinder is option B i.e 35 mL

Answer:

a)  a right triangle,  b)   x = 0.167 m

Explanation:

a) It is asked to find which geometry figure describes the movement of the ant.

Let's use trigonometry with the angles measured in radians

             tan θ = y / x

             tan θ = 6/10  

             θ = tan⁻¹ 0.6

             θ = 0.54 rad

this value is equal to the upward slope therefore the geometric body that describes the movement is a right triangle

b) it is asked to find the horizontal displacement for a vertical displacement of y = 0.1 cm x = y / tan tea

            x = 0.1 / tan 0.54

            x = 0.1668 m

            x = 0.167 m

The average speed of the girl is 1.2 m/s.

Average velocity is defined as the trade in position or displacement (∆x) divided by the time durations (∆t) wherein the displacement takes place. The common velocity can be effective or negative depending upon the sign of the displacement. The SI unit of average velocity is meters per second (m/s or ms-1).

Given;

Total distance = 40 + 20 = 60 M

Displacement = 40 - 20 = 20 m south

total time = 40 + 10 = 50 seconds

Average speed =  total distance / total time

                          = 60/50

                          = 1.2 m/s

average velocity = total displacement / total time

                            = 20 / 50

                             = 0.4 m/s due south.

Average velocity is calculated by means of dividing your displacement (a vector pointing out of your initial role in your final position) through the entire time; the average pace is calculated by way of dividing the overall distance you traveled by means of the total time.

Answer:

The atom consists of a tiny nucleus surrounded by moving electrons. The nucleus contains protons, which have a positive charge equal in magnitude to the electron's negative charge. The nucleus may also contain neutrons, which have virtually the same mass but no charge.

Explanation:

Answer:

Explanation:

so her displacement is the distance from the start... she's now at a point (6,5) away from the start..  so what's the length of the side of the right triangle made by one side of 6 and the other of 5

Yes.. use Pythagoras theorem to solve this

C =  √([tex]6^{2}[/tex]+[tex]5^{2}[/tex])

C = √(36 + 25)

C = √61

C = 7.810  miles.. north east of where she started

C = 7.8 miles NE   :P

Answer:burning paper

Explanation: it’s burned, you can’t put it back together ( you can’t undo a chemical reaction/ change )

Answer:

a) Eg = 3,060.72 j

b) Ek = 2,080 j

c) Etotal = 5,140.72 j

Explanation:

The given parameters are;

The mass of the person, m = 65 kg

The height of the person, h = 4.8 m

The speed of the person, v = 8.0 m/s

a) The gravitational potential energy, [tex]E_g[/tex] = m·g·h

Where;

g = The acceleration due to gravity ≈ 9.81 m/s²

∴ Eg = 65 kg × 9.81 m/s² × 4.8 m = 3,060.72 j

Eg = 3,060.72 j

b) The kinetic energy, Ek = 1/2·m·v²

∴ Ek = 1/2 × 65 kg × (8.0 m/s)² = 2,080 j

Ek = 2,080 j

c) The constant total Mechanical Energy, Etotal = Eg + Ek

∴ Etotal = 3,060.72 j + 2,080 j = 5,140.72 j

Etotal = 5,140.72 j.

Answer:

Object X reflects yellow and object Y reflects none.

Explanation:

We are able to see the colors of different objects because the light rays falling on the surface of an object reflects back few or none of the colors to our eyes. We see the color that is reflected back to our eyes.

In the context, Marcy has two objects, X and Y. We see that object X is yellow in color because as the light rays falls on the object X, it absorbs all the colors of the spectrum and reflects the color yellow back to our eyes. So we can see that the object X is yellow.

Similarly, when spectrum light falls on the surface of the object Y, it absorbs all light in its body and reflects none of its colors. So the object Y appears to be black to our eyes.

Answer:

The angle wires have to be placed to experience full force is such that the angle between the direction of current flow and the direction of the magnetic field is 90°

Explanation:

The direction of the force acting on a conductor through which a charge flows  is given by Flemings Left Hand Rule which states that the direction of the force acting on a conductor carrying a current of charge is perpendicular to both the direction in which the current is flowing and the direction of the magnetic field

Therefore, wires carrying flowing charges has to be placed such that the direction of charge (current) flow is perpendicular (at 90°) to an existing magnetic field to experience (maximum) full force

Answer:

230.4 N

Explanation:

Applying,

F = kqq'/r²..................... Equation 1

Where F = Electric force, k = Coulomb's constant, q = charge in the ballon, q' =  charge in the denium, r = distance between the charges.

From the question,

Given: q = -8.0×10⁻⁶ C, q' = +8.0×10⁻⁶ C, r = 0.05 m

Constant: k = 9×10⁹ Nm²/C²

Substitute these values into equation 1

F = (9×10⁹×8.0×10⁻⁶×8.0×10⁻⁶ )/0.05²

F = (576×10⁻³)/0.0025

F = 230.4 N.
