A woman Standing and watching stars on a cool and calm night will lose most of her body heat by the mechanism of radiation.

In conduction method of thermal energy transfer energy take place between the objects by using the direct contact between the particles.

Convection is a method of heat transfer in which fluids do the heat transfer generally.

Evaporation method of heat transfer it is just a method cooling down the temperature of the body.

The only method of heat transfer that is valid in this case is radiation in which the heat transfer take place by the use of electromagnetic radiations coming directly from the sun or the moon or the stars.

The motion of an object can be described by its speed, position and direction. Option D

Th term motion has to do with the change in the position of an object. We have to note that if an object changes its position within a given time interval then we can say that the object has moved.

The rate at which an object moves is called the speed of the object. If the object move fast then the speed of the object is high. If the the object moves slowly then the object has a quite low speed.

A regular polygon's interior angles add up to 3060° of a 19 sided polygons.

Polygons are defined as a flat shape surrounded by sides, or line segments.

It can be defined as a plane figure whose description is given by a closed polygonal chain made up of a finite number of straight line segments.

It can also be defined as any closed curve made up of a number of connected line segments that do not cross one another.

Sum of interior angle = (p - 2) x 180°

Where p = 19

Sum of interior angle = (19 - 2) x 180°

                                   = 17 x 180°

                                   = 3060°

Answer:

30.3 m

Explanation:

vf = final velocity = 0 at the apex

vo = original velocity = 24.39 m/s

a = - 9.81 m/s^2

vf = vo + at

0 = 24.39  -9.81 t   shows t= 2.486 s

df = final height

df = vo t  + 1/2 a t^2

An apparent brighter blue star.

The hue of light emitted by a star depends on its surface temperature. Yellow stars are hotter than red stars, and yellow stars are hotter yet than blue stars.

The difference between a star's magnitude in one filter and its magnitude in another filter is that star's color index. Color indices can be calculated using any filter, but some of the more used ones are B-V and V-R. Red wavelengths are B, green wavelengths are V, and blue wavelengths are B. The star is bluer (and hotter) if B - V is small than if B - V is high since magnitudes decline with increasing brightness.

The particles of a solid have fewer options available to them than the particles of the same molecules in a liquid.

Because the interactions between particles are stronger in a solid, there are fewer ways that they can move around, and this limits their freedom to change position.

In a liquid, there is no boundary. The amount of fluid you have depends on the container and the size of your container; the more surface area you have, the more fluid there is. The only way to define the boundaries of a solid is by using a mathematical formula.

For example, if you stand at the bottom of a cliff, then drop something off it, making for another particle of equal size which is placed at some random point on the cliff (this is not obvious), then what you will find at the end of your experiment is that it is less probable that there will be one particle in front of the second one than it would be if an equal volume of liquid was present instead.

Light rays bend towards the normal because they slow down when moving from a rarer medium to a denser medium.

The reason behind the refraction of rays of light towards normal is that because slow down when moving from a rarer medium to a denser medium.

If the light rays enter any substance with a higher refractive index (which includes air into glass) then it will slow down. The light always bends towards the ordinary line. If mild travel enters into a substance with a lower refractive index (which includes from water into the air) then it will speed up. Therefore the ray of light always refracted towards the normal.

When the light rays enter from the air into a denser medium like water or glass then the ray of light will refract towards the normal. When light travels from a denser medium into the air, it will refract away from the normal.

So we can conclude that light rays slow down when moving from a rarer medium to a denser medium.

A is 2.56 . A function is a mathematical relationship in which the values of one or more independent variables influence the values of a single dependent variable.

The independent variable determines the dependent variable through function (s).

A variable is a value that is stored, and a function is a program (I can't think of another word for it). So you can have a n variable that stores the value 1, and a function called print(n) that prints whatever is inside the parenthesis, (n in this example), so the value stored in n is printed.

Therefore,

y = 13.9, x = 4.45, and B = 8.87,

13.9=A × 2(4.45) - 8.87

Switch sides

A × 2(4.45) - 8.87 = 13.9

Remove parentheses:

A × 2 × 4.45 - 8.87 = 13.9

Multiply the numbers: 2 × 4.45 = 8.9

8.9 A - 8.87 = 13.9

Multiply both sides by 100

8.9 A × 100-8.87 × 100= 13.9 × 100

Refine

890 A - 887 = 1390

Add 887 to both sides

890 A - 887 + 887 = 1390 + 887

sin θ = 10 m / 20 m

sin θ = 1/2

sin θ = 0.5

θ = arc sin(0.5)

θ  = 30⁰

The magnitude of the net force on the block while it is sliding is calculated as follows;

F(║) = F(net) = mg sinθ

The maximum speed with which a 1200- kg car can round a turn of radius 92.0 m on a flat road if the coefficient of static friction between tires and road is 0.40 will be 18.6 m/s.

A force that holds an object at rest is called static friction. The definition of static friction is: The resistance people feel when they attempt to move a stationary object across a surface without actually causing any relative motion between their body and the surface they are moving the object across.

The frictional force acting on the car is given by:

[tex]F_{f} =umg =(0.40) (1200kg)(9.81m/s^{2} )=4709N[/tex]

The force applied to an item in curved motion that is pointed toward the axis of rotation or the centre of curvature is known as a centripetal force. Newtons are used to measure centripetal force. The direction of the centripetal force is always perpendicular to the direction in which the item is moving.

However, the centripetal force, which keeps the car turning in a circle, is also related to the frictional force:

[tex]F_{f} =F_{c} =m \frac{v^{2} }{r}[/tex]

Where v is the fastest the car can travel while still in the turn. We may get the value of v by rearranging the formula and substituting r=88.0 m:
