Answer:

analyze

Explanation:

It would be 0.01023.

0.010229 has 5 sig. fig.'s (leading zeros do not count)

So rounding to 4 sig. fig.'s is just a matter of rounding off the last digit, which leaves you with 0.01023.

Here we can study the different temperatures of each one of the layers of the sun.

We will find that the way that the scientist can identify which layer are they studying is "The lowest temperatures are from the photosphere."

A brief description of the temperature of each layer is:

Center of the sun: about 15 million K

Radiative Zone:  Goes from 7 million K to 2 million K.

Convection Zone: goes from 2 million K to 5800K

Photosphere: Is in average 5800 K , but there are sunspots with lower temperatures, of around 3800 K.

Chromosphere: goes from 4300 K to  8300 K

Corona: Around 2 million K.

So now we can analyze each of the options to see which ones make sense.

A) The highest temperatures are from the corona.

This is false, we can see that in the center and in the radiative zone we have larger temperatures than in the corona.

B) The lowest temperatures are from the photosphere.

While on average the temperature of the photosphere is larger than the smaller temperature of the chromosphere, in the photosphere we have the sunspots, and there we have the smallest temperatures in the whole sun, so this is true.

C) The lowest temperatures are from the core (or center).

Clearly false, there we have the larger temperatures.

D)  The highest temperatures are from the radiative zone.

Again false, the larger temperatures are in the center.

So the only true option is "The lowest temperatures are from the photosphere."

Answer:

C. When ice melts, it absorbs energy.

Explanation:

When ice melts, it is getting hotter by absorbing energy and changes from a solid to a liquid. This is an endothermic reaction.

Answer:

49.050 KW

Explanation:

= mgh

=5000×9.81×10

=490500J

power = workdone/Time taken

= 490500/10

= 49050 watts

= 49.050kW

Nikki has a momentum of 45 Kilogram meters per second and a mass of 30 Kilograms. then her velocity would be 1.5 meters per second

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

Mathematically the formula of the momentum is

P = mv

where P is the momentum of the particle

m is the mass of the particle

v is the velocity by which the particle is moving

As given in the problem Nikki has a momentum of 45 Kilogram meters per second and a mass of 30 Kilograms

P = 45 Kilogram meters per second

m = 30 Kilograms

By substituting the values of the momentum and the mass in the formula of the momentum

P = mv

45 = 30 ×v

v = 45/30 meters per seconds

v = 1.5 meters per seconds

Thus, Nikki weighs 30 kilograms and moves at a 45 kilogram per the second momentum. subsequently, her velocity would be 1.5 meters per second.

therfore ,2 s.

Again,

h=ut -1 gt square

Explanation:

constant acceleration

because when the object's velocity is changing then the object is accelerating or decelerating

as acceleration describe changing of velocity so the answer is constant acceleration

Acceleration is defined as the rate of change of velocity.

Acceleration = (Change in velocity) / time taken

Acceleration = (Final velocity - initial velocity) / time

As the object velocity changes by the same amount in each second, it means the acceleration is constant.

Explanation:

molecular formula consists of the chemical symbols for the constituent elements followed by numeric subscripts describing the number of atoms of each element present in the molecule. The empirical formula represents the simplest whole-integer ratio of atoms in a compound.

Answer:

The symbollic representation of a molecule of an element or a compound present in a molecule is called molecular formula.

For example: molecular formula of sodium chloride is NaCl.

Hi,

The man on the ground in standing position has more pressure. This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.

To the point, a man standing position on the ground had more pressure.

More is the area of contact, less is the pressure efforted.

Thank you...

Answer:

Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

You can write like "30.56 m/s".

Answer:

Below

Explanation:

You can convert km/h to m/s by dividing the value by 3.6

      110 km/h / 3.6 = 30.5556 m/s

*not sure if your teacher wants you to round to sig figs for this but here it is anyways. Because 110 has 2 sig figs it would be :
