Explanation :

Conduction : Conduction is the transfer of heat due to collision between the molecules in the substance.

It is the way of energy transferred in the solid.

Convection : When  air is heated and then travels away from the source that means air caries the heat along.

it is called convection.

It is the way of energy transferred in the air and liquid.

Radiation : radiation generate from the emission of electromagnetic wave.

electromagnetic wave carry the energy away from the source which is emitting the radiation.

It is the way of energy transferred in the vacuum.

States of matter depend in part on the___<br> of an item.
harina [27]

Answer:

Explanation:

Matter occurs in four states: solids, liquids, gases, and plasma.

States of matter are generally described on the basis of qualities that can be seen or felt.

A solid has a definite shape and volume because the molecules that make up the solid are packed closely together and move slowly.

You get a new pair of sunglasses as a birthday gift from a friend. When wrapping the present, your friend has removed the price
Gwar [14]

Answer:

Explanation:By using the sunglasses while looking at If your sunglasses are polarized, instead of only seeing the surface of a lake or river, you will suddenly be able to see through the glare and into the water below.

Another one is by comparing two sunglasses, hold your glasses and another one simultaneously and look through both pairs at the same time. Then, rotate one pair of sunglasses about 60 degrees. If both pairs of glasses are polarized, the overlapping area will darken as they filter out excess light. If your pair isn't polarized, however, you won't notice any difference.

Also it can be determined by simple computer test If you rotate your glasses sideways while looking at a computer monitor through polarized glasses, portions of your screen will become blank or go dark. The same also applicable to LCD display screens such as the ones on a gas pump.

The froghopper, Philaenus spumarius, holds the world record for insect jumps. When leaping at an angle of 58.0° above the horizo
Norma-Jean [14]

Answer:

0.528m

Explanation:

a)58.7 cm = 0.587 m

Let g = 9.8m/s2. When the frog jumps from ground to the highest point its kinetic energy is converted to potential energy:

E_p = E_k

mgh = mv^2/2

where m is the frog mass and h is the vertical distance traveled, v is the frog velocity at take-off

v^2 = 2gh = 2*9.8*0.587 = 11.5

v = \sqrt{11.5} = 3.4 m/s

b) Vertical and horizontal components of the velocity are

v_v = vsin(\alpha) = 3.4sin(58^0) = 2.877 m/s

v_h = vcos(\alpha) = 3.4cos(58^0) = 1.8 m/s

The time it takes for the vertical speed to reach 0 (highest point) under gravitational acceleration g = -9.8m/s2 is

\Delta t = \Delta v / g = \frac{0 - 2.877}{-9.8} = 0.293s

This is also the time it takes to travel horizontally, we can multiply this with the horizontal speed to get the horizontal distance it travels

s_h = v_ht = 1.8*0.293 = 0.528 m
