If there is 8 g of a substance before a physical change, how much will there be afterwards? 0 g 4 g 8 g 16 g

Answers

Answer 1

Answer:

8g

Explanation:

This is because of mass conservation

For example, if you have 8g of ice and it melts, although it is now water, it is still 8g.

Answer 2

Answer:

8 grams

Explanation:

Mass does not change and is not affected due to conversion of states.

The mass is same and constant.

1) For example, if taken a cube of 8 grams of ice which melts to water.

2) The mass of the water will be 8 grams.

3) Hence, mass does not change following law of conversion of mass.

Which object Can an S way travel

Answers

Answer:

S-waves can travel only through solids

Explanation:

S-waves can travel only through solids, because only solids have rigidity. S-waves cannot travel through liquids or gases. Because the earth's mantle becomes more rigid as its depth below the asthenosphere increases, S-waves travel faster as they go deeper in the mantle.

ALGEBRA Find the value of n and WX if Wis between X and Y, WX = 6n - 10, XY = 17, and WY= 3n. A. n= 3; WX-8 B. n = 3; WX = 9 C. n= 9; WX= 27 D. n= 9; WX = 44​

Answers

Answer:

Option (a) is correct n = 3 and WX = 8

Explanation:

It is given that, W lies in between X and Y. It means W is the mid point of X and Y. So,

XY = WX+WY .....(1)

We have, WX = 6n - 10, XY = 17, and WY= 3n

Putting the values in equation (1)

17 = 6n - 10 +3n

17 = 9n-10

Adding 10 both sides,

17+10 = 9n-10+10

27 = 9n

⇒ n = 3

We have, WX = 6n - 10

Put n = 3,

WX = 6(3) - 10

WX = 18-10 = 8

Hence, n = 3 and WX = 8

Point N is on line segment M O ‾ MO . Given N O = 2 x − 3 , NO=2x−3, M O = 3 x + 5 , MO=3x+5, and M N = 2 x + 3 , MN=2x+3, determine the numerical length of M O ‾ . MO .

Answers

Answer: The length of MO is 20 units.

Explanation:

It is given that Point N is on line segment M O.

Using segment addition property, we get

[tex]MO=MN+NO[/tex]

Given values are NO=2x−3, MO=3x+5, and MN=2x+3.

[tex]3x+5=(2x+3)+(2x-3)[/tex]

[tex]3x+5=4x[/tex]

[tex]5=4x-3x[/tex]

[tex]5=x[/tex]

The value of x is 5.

[tex]MO=3x+5[/tex]

[tex]MO=3(5)+5[/tex]

[tex]MO=15+5[/tex]

[tex]MO=20[/tex]

Therefore, the length of MO is 20 units.

The movement of tectonic plates is inferred by many scientists to be driven by
A) solidification in the lithosphere
B) density differences in the troposphere
C) convection currents in the asthenosphere
D) tidal motions in the hydrosphere

Answers

Answer:

c

Explanation:

layers of the earths crust

The movement of tectonic plates is inferred by many scientists to be driven by convection currents in the asthenosphere. Option (c) is correct.

What do you mean by Asthenosphere?

The asthenosphere is a solid portion of the upper mantle that is so heated that it can flow and behave like plastic. The asthenosphere supports the lithosphere. The asthenosphere can flow like toothpaste despite being solid. The topmost concentric layers of our globe are the asthenosphere and lithosphere.

Convection currents are created by the intense heat and pressure that exists within the earth. The tectonic plates that make up the earth's crust move as a result of these currents.

Therefore, Option (c) is correct. The movement of tectonic plates is inferred by many scientists to be driven by convection currents in the asthenosphere.

The correct option is A.

Antarctica's location and climate changed over the last 200 million years because Antarctica moved southward, resulting in a colder climate.

How is Antarctica affected by climate change?

The warming of the Antarctic Peninsula is causing changes to the physical and living environment of Antarctica. The distribution of penguin colonies has changed as the sea ice conditions alter. Melting of perennial snow and ice covers has resulted in increased colonization by plants.

How is Antarctica a crucial element in the debate on climate change?

Antarctica is a crucial element in the debate on climate change because it is the only place in the world that has never sustained a human population and thus remains relatively pristine. Moreover, it holds in its ice caves half-million- year old carbon records trapped in its layers of ice.
