Answer:
Gravity
Explanation:
Gravity was founded by famous physician Sir Izak Newton.The gravity is a phenomenon by which every object in the universe attracts eachotherNewton discovered gravity by the falling apple from tree.The following factors contribute to plate tectonics: The Mantle's Convection. Mountain push gravitational force at the spreading ridges, Block pull gravitational force in subduction zones. Hence, option B is correct.
What is gravitational force ?The gravitational force, which is what pushes mass-containing objects toward one another. We frequently consider the pull of gravity from the Earth. Your body is kept on the ground by this force. However, all mass-bearing objects are pulled toward one another by gravity.
Population growth and changes in people's wants and activities are the main causes behind this. Changes in the overall levels of output and consumption are caused by these main movers.
The driving forces put strain on the environment through these modifications to production and consumption. In the direction of motion, gravity produces an active driving force.
Thus, option B is correct.

A sample of uranium absorbs 27.16 kJ of energy and changes temperature by 347.6 C. If 27.17 J/(1C * 1 mole) for uranium, the how many mole of U are in the sample?
Answer:
Q = 2.877 mole (4 sig. figs.)
Explanation:
Using Q = m·c·ΔT => m = Q/c·ΔT
Q = 27.16 Kj
c = 27.17 j/g·°C = 0.02717 Kj/g·°C
ΔT = 347.6 °C
Q = 27.16 Kj/(0.02417j/mol·°C)(347.6°C) = 2.87.6869965 mol (calc. ans.)
= 2.877 mole (4 sig. figs.)

Batteries allow us to store energy for when it’s needed, such as starting a car engine or jump-starting another car whose battery has lost its charge. But batteries cannot operate without chemical reactions. What kind of energy do you think is stored in the substances within the battery?
Answer:
Chemical energy
Explanation:
I hope this helped you!
Batteries store the energy in the form of chemical energy that chemical energy is converted into electrical energy. Chemical energy is used to stored in the substances within battery.
What is electrochemical energy ?The conversion of chemical energy into electrical energy or vice versa is called as electrochemical energy . This includes reactions transferring electrons, redox reactions .
Redox reaction in which reduction and oxidation takes place simultaneously. Reduction, when a substance receives one electron. Oxidation when a substance gives away one electron.
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
Thus, chemical energy is used to store in the substance within battery.

tornadoes form when updrafts from thunderstorms begin to _____
First answer that is correct gets brainly
Tornadoes form when updrafts from thunderstorms begin to interact with strong wind shear and develop a rotating column of air.
Updrafts are powerful vertical currents of air that occur within thunderstorms, caused by the rapid heating of the Earth's surface and the subsequent convective process. These updrafts carry warm, moist air upward, creating a conducive environment for the formation of severe weather phenomena.
When the updrafts encounter wind shear, which is the change in wind speed and direction with height, it can lead to the development of horizontal vorticity. Wind shear creates a rotating motion within the storm, where air at different heights starts to rotate at different speeds, generating a horizontal spin.
As the updraft continues to intensify, it tilts the rotating column of air from horizontal to vertical, forming a mesocyclone. The mesocyclone is a critical component in tornado formation. It acts as a localized area of strong rotation within the storm, extending from the cloud base to the mid-levels of the atmosphere.
Under specific conditions, such as the presence of a strong updraft, a well-developed mesocyclone, and further enhancement from other atmospheric factors, the mesocyclone can contract and intensify into a tornado. The process is complex and influenced by various meteorological factors, but the interaction between updrafts, wind shear, and the development of rotation plays a fundamental role in tornado formation.

You can usually confirm the charge associate degree particle unremarkably has by the element's position on the periodic table: The alkali metals (the IA elements) lose one negatron to create a ion with a 1+ charge. The alkaline-earth metal metals (IIA elements) lose 2 electrons to create a 2+ ion.
Nonmetals type negative ions (anions). A range 7|chemical element|element|gas} atom should gain 3 electrons to possess an equivalent number of electrons as AN atom of the subsequent gas, neon. Thus, a gas atom can type AN ion with 3 additional electrons than protons and a charge of 3−.

2.8 dm3 of gas X at STP has equal mass with 11.2 dm3 of C2H6 at STP. What is
the number of mole if gas X has 30 grams?
Answer: o.125 moles of gas X with a molar mass of 240
Explanation:
2.8 dm3 of gas X at STP has equal mass with 11.2 dm3 of C2H6 at STP. What is the number of mole if gas X has 30 grams?
the molar volume of any gas at STP is the volume of 1 mole at STP
and is 22.4 L
the C2H6 has a volume of 11.2L at STP so it has 0.5 moles
C2H6 has a molar mass of (2 X 12) +(6 X 1) = 24 + 6 = 30
0,5 moles weighs 15 gm at STP with
so 15 gm at STP with 2.8 L for gas X
PV=nRT
P=1 atm
T =273.2k
V =2.8
R =0.082
n = PV/RT = (1 X 2.8)/(0.082 X 273.2) =0.125 moles of gasX
the weight of gas X is 30 gms
so 30/.125 =240 g/mole = molar mass of gas X
