how does the sun rise and set
a.earth orbit around the sun
b.The sun is center of solar system
c.earth rotates on it tilted axis and orbit around the sun at the same time​

Answers

Answer:

c. earth rotates on it tilted axis and orbit around the sun at the same time​

Explanation:

Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.

This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun. Thus, this makes us to experience day and night (sun rise and sun set) due to the rotation of planet about its axis.

Hence, the sun rise and set because the earth rotates on it tilted axis and orbit around the sun at the same time​

Tarzan is swinging back and forth
on a 6.25 m long vine. What is the
period of his oscillation?
(Unit = s)

Answers

Answer:

5.02s

Explanation:

I got it right in acellus :)

The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.

Calculation of the period:

Since

Length L = 6.25 m

g = 9.8 m/s²

So,

T = 2π√(L/g)

T = 2π√(6.25 / 9.8)

T = 5.01 sec

Hence, The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.

What is the interference of waves?

The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.

The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.

From the constructive interference;

[tex]\rm L_1-L_2 = 2 \lambda \\\\ 2\lambda=8-6 \\\\ \lambda= 1 \ m[/tex]

The frequency is;

[tex]\rm f= \frac{c}{\lambda} \\\\ f= \frac{343}{1} \\\\ f= 343 \ Hz[/tex]

Hence,the frequency for the maximum constructive interference will be 343 Hz.

Answers

Answer:

As par circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.

What is circle graph?

Pie charts are another name for circle graphs. The graph is shaped like a circle, with many wedges that each represent a portion of the overall.

The circle graph is commonly referred to as a pie chart since these wedges frequently resemble pie slices. The circle graph's angles are proportionate to the quantity they each represent.

According to circle graph:

Total number of student in the particular school = 2π radian.

So, one-fourth of total number of student in the particular school = 2π/4 radian

= π/2 radian.

Hence, according to circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.

Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 5.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle?

Answers

Answer:

Particle A: K.E = 38.3 J

Particle B: K.E = 7.67 J

Explanation:

Given that Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 5.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle?

The total kinetic energy of Particle A and particle B should be equal to 46 J

Since the mass of A is 5.00 times the mass of B, then, the K.E energy of each particle can be calculated by using ratio.

5 + 1 = 6

K.E for particle A

5 /6 × 46 = 230 / 6 = 38.3 J

K.E for particle B

1/6 × 46 = 46 / 6 = 7.67 J

Velocity can be described as the same thing as speed but with _________________ included

Answers

Answer:

Direction

Explanation: Hope this helps!

Answer:

nvm its direction :))

Explanation:

Speed and velocity both represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity are measured in the same units: meters per second or m/s.

Velocity is a measure of both speed and direction of motion. Velocity is a vector, which is a measurement that includes both size and direction. Velocity can be represented by an arrow, with the length of the arrow representing speed and the way the arrow points representing direction.
