What is a light year?

Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

The speed of light measures the space traveled by electromagnetic waves every second.

In a vacuum, electromagnetic waves propagate at a constant velocity of approximately 299,792,458 meters per second.

In other words we can state that the speed of light refers to the rate that light travels through empty space.

Light-year is a unit of measurement used to calculate distances in astronomical space, i.e. where planets, stars, comets and so on are found.

The distances between the stars are huge, so to measure the immense dimensions of the universe requires the application of a special unit of measurement: the light year.

Because of this gigantic distance, the distance between the stars is measured in light years.

An object launched at 65 degrees from the horizontal would have the same range
(distance travelled) as an object launched from? Write only the WHOLE number with
no units (example: 65)

Answers

Answer:

An object launched from 65° will have the same range as an object launched from 25°

Explanation:

The formula for the horizontal range, R, is given as follows;

[tex]R = \dfrac{v \times sin(2\cdot \theta)}{g}[/tex]

Therefore, given that sinθ increases from 0 to 1 for θ values from 0 to 90° and decreases from 1 to 0 for θ values from 90° to 180°, and that the values of sin(θ) are positive in the first and second quadrant, we have that for the given angle, θ = 65°, the range is therefore;

[tex]R = \dfrac{v \times sin(2\times 65 ^{\circ})}{g} = \dfrac{v \times sin(130 ^{\circ})}{g}[/tex]

The location of 130° = Second quadrant

A rotation of 130° in the counterclockwise is equivalent to a rotation of 50° in the clockwise direction

Therefore, we have sin(130°) = sin(50°)

Therefore, the range for 130°/2 = 65° is the same as the range for 50°/2 = 25° and an object launched from 65° will have the same range as an object launched from 25°.

What collides and creates a movement of heat called conduction?

A. photons

B. compounds

C. Molecules

D. atoms

Answers

Answer:

c.

Explanation:

Molecules collide and create a movement of heat called conduction.

What is conduction?

Conduction is defined as a process  as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to  a body which is cold.

In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules  while in liquids and gases it is due to the random motion of the molecules ,

When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state  conduction 2) transient conduction.According to the type of energy conduction is of three types:

1) heat conduction

2) electrical conduction

3)sound conduction

A physics student drops a water balloon from an upstairs window. The window is 26.45 m
from the ground. How long does it take for the balloon to hit the ground? (Round to the
nearest tenth)

Answers

Answer:

Explanation:

Given:

Distance S = 26.45m

Using the equation of motion

S = ut+1/2gt²

26.45 = 0+1/2(9.81)t²

26.45 = 4.905t²

t² = 26.45/4.905

t² = 5.392

t = 2.528s

Hence the it took the balloon 2.52s to reach the ground

A person jogs 4.0 km in 32 minutes, then 2.0 km in 22 minutes, and finally 1.0 km in 16 minutes. What is the jogger's average speed in km per minute?​

Answers

Answer:

0.0928km/min (4dp)

Explanation:

To find the jogger's speed in km per minute, we just need to divide the number of km jogged by the time in minutes it took to jog that distance. This will give us the distance they jogged every minute which is their speed.

4km in 32 minutes:

4/32 = 0.125km/min

2km in 22 minutes:

2/22 = 0.091 (3dp)km/min

1km in 16 minutes:

0.0625km/min

Now to find the average speed of these 3 speeds, we just add them all together and divide by how many values there are (3 values).

Average (mean)  = [tex]\frac{0.125+0.091+0.0625}{3}[/tex]

Average = 0.2785/3

Average speed of jogger = 0.0928 (4dp) km/min
