The total distance covered by Jhen is 210 m and the total displacement is zero (0).

The total distance covered by Jhen is calculated as follows;

D = 70 m x 3  (since 1 lap is equal to one length of the pool = 70 m)

D = 210 m

The displacement of Jhen is the change in the final position and the initial position of Jhen.

After 3 laps, the final position = the initial position

Displacement = 0

Thus, the total distance covered by Jhen is 210 m and the total displacement is zero (0).

The phase of the Moon changes from new Moon to a full Moon when the Moon moves around the earth until it is between the Sun and the Earth.

The moon is a large massive body which is found in orbits around the earth.

The moon is said to be the satellite of the earth and orbits the earth in the form of a moon cycle or phases.

The moon cycle occurs when the move moves around the earth from the full moon to a new moon.

Therefore, the phase of the Moon changes from new Moon to a full Moon when the Moon moves around the earth until it is between the Sun and the Earth.

Explanation:

Following the Law of reflection we can assume that the expression for the distance from the point of reflection on the water to the bottom of the light pole is d = (H (L-d)) / h.

The Law states that the reflection angle -θ₂- of an incident ray on a reflecting surface will be equal to the incidence angle -θ₁- of that ray.

Both angles, the reflection and the incidence one, are measured conserning the normal to the surface.

The law of reflection derives from Fermat's principle and states that the triangle formed between the incident ray and the surface, and the triangle produced by the reflected light and the surface are the same.

In the exposed example, if

If,

θ₁ = θ₂

h/L-d = H/d    

Then, the distance from the point of reflection on the water to the bottom of the light pole, d is

d = (H (L-d)) / h

Answer:

0.82

Explanation:

constant velocity.means acceleration a = 0, so net force = 0

F - μmg = ma = 0

so μ = F/(mg) = 200/(25*9.8) = 0.82

Answer:

Solve it simply,

Vi = 20 m /sec

Vf = 0 ( at max. height)

g = - 9.8 m/ sq. sec. ( -ve sign shows that the motion of the body is in opposite direction to that of gravity)

Height it gains=h = ?

time taken by the body=t=?

Using 3rd equation of kinematics,

2gh=Vf ˄2 – Vi˄2

implies that

h = Vf ˄2 – Vi˄2 / 2a

h = 0˄2 - (20)˄2 / 2(-9.8) = - 400/ -19.6

h = 20.4 m

So the maximum height the body can gain is approximately equal to 20.4 m.

Now , using 1st equation of kinematics:

Vf = Vi + at implies that,

t = Vf - Vi/g = 0 - 20/ - 9.8 = 2.04 sec.

So, it will take 2.04 sec. to get the max. height.

Note: in simple approximation if we take g =- 10 m/ sq.sec then the max. height the body can attain will be 20 m and the time required for it, is 2 sec.

Answer:

The mass of the object.

The friction involved.

The amount of force applied to the object.

The gravity pulling on the object.

Explanation:

I think that all answers are correct with the right explanation.

the mass is what is pulled on by gravity to determine weight.

friction opposes motion.

gravity pulls everything to the earth's centre

force makes an object to either stop, change direction or increase the velocity of an object depending on the amount.

The main focus of the nervous system is to have nerve fibers pass information throughout the body. The nervous system is crucial for keeping our bodies functioning. It is divided into two main parts, the peripheral nervous system, which are the nerves running throughout the body, and the central nervous system, which is the brain and spinal cord. The nervous system communicates signals between body parts and the brain. The nervous system keeps all body parts functioning through these signals.

What patterns can we observe in the sky?

Stars create observable patterns in the form of “dots”, which can be created to make pictures. These are called constellations. The constellations can move in position or location across the sky, but each “piece” in the constellation does not move because stars do not move or change position in relation to other stars.

What are the 12 phases of the moon?

The moon phases in order are new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning crescent.

What pattern does the Moon travel around the Earth?

circular The moon orbits the earth in a nearly circular pattern every 27.3 days. The moon's orbit is tilted approximately 5 degrees off of the path of the plane of the ecliptic (or the path that the sun appears to trace across the sky), and orbits at a distance of almost 240,000 miles from the earth.

What patterns do you notice about the Moon and sun across the sky?

The sun follows the same pattern as the moon; it appears to rise in the east and set in the west. The Sun is Always Shining The sun is always shining, even at night when we cannot see it. The sun follows the same pattern as the moon; it appears to rise in the east and set in the west.

What causes the pattern of the Moon?

One important thing to notice is that exactly one half of the moon is always illuminated by the sun. ... So the basic explanation is that the lunar phases are created by changing angles (relative positions) of the earth, the moon and the sun, as the moon orbits the earth.

Explanation:

here are 8 standard phases of the moon, which is demonstrated in this particular diagram very clearly. There’s the new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, waning crescent, and then back around to the new moon.

The most obvious patterns of the moon are the phases of the moon, which move in a month-long cycle. Because the moon reflects its light from the sun, only the part of the moon that faces the sun is visible. As the moon revolves around the Earth, its shadow covers part of its surface.

The Moon. In the natal chart, the position of the Moon by sign shows how we emote and respond to our environment, as well as our instinctual habits, especially in our homes and in private. By house, the Moon’s position shows which areas of life we feel the most “at home” or comfortable.

Patterns in the natural and human designed world can be observed, used to describe phenomena, and used as evidence. In the previous lesson, we determined two patterns for the moon: 1) The moon changes shapes. 2) The moon appears to rise, move across the sky, and set. In today's lesson, we focus in on the first pattern-- the moon's phases.
