Typically, people think of a lava flow when they think of volcanoes. However, some eruptions are mostly ash and steam released into the atmosphere. This type of volcanic eruption is blamed for causing what is referred to as a "Little Ice Age" starting in the 13th century. The ash and steam blocked the sun's rays causing extreme cold and agricultural difficulty which lead to massive decreases in populations.

Describe how the energy from the sun is vital to life. In your response, be sure to include:

1. The form(s) of energy that the sun provides to the Earth.

2. How energy from the sun is transformed on the Earth.

3. At least two ways humans depend on the sun's energy for survival.

Explanation:

Molecules collide and create a movement of heat called 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

Explanation:?

The answer would be newtons.

Answer:

a)     x = 39.9 m

Explanation:

To find the components of a vector we can use trigonometric relationships. Since they indicate that the angle is 37º north of east, this angle is measured counterclockwise from the x-axis, therefore using trigonometry.

          cos θ = x / d

          sin θ = y / d

where the angle is 37º and the distance d = 50 m

          x = d cos θ

          y = d sim θ

let's calculate

        x = 50 cos 37

        y = 50 sin 37

        x = 39.9 m

        y = 30.1 m

the answer is b

Explanation:

Answer:

All that is necessary is that car A has a greater speed (is moving faster). ... A fullback is running down the football field in a straight line. ... At 1 second, he is on the 10-yard line; at 2 seconds, he is on the 20-yard line; at 3 seconds, he is on ... Since average velocity is displacement over time, his average velocity is also 0 m/s.

Explanation:

Answer:

45 yards of displacement from the 20 yard point

Explanation:

take the 65 and subtract 20 from it and that will give you your displacement.

Answer:

To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)

To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)

To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)

To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

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

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°.

Answer:

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

[tex] a = \frac{f}{m} \\ [/tex]

f is the force

m is the mass

From the question we have

[tex]a = \frac{500}{3000} = \frac{5}{30 } = \frac{1}{6} \\ = 0.166666...[/tex]
