What is the independent variable?
Answer:
An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable.
Explanation:
:)
Heres some defs- a variable (often denoted by x ) whose variation does not depend on that of another. The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. ... The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable.
A rectangular metal is 25 dm long, 525 mm wide, and 1.5 m high. This metal weighs 250 lb. Calculate its density in g /mL
Answer:
d = 0.057 g/mL
Explanation:
Given that,
The dimensions of a rectangular metal is 25 dm long, 525 mm wide, and 1.5 m high.
The weight of the metal is 250 lb
We need to find the density of the metal in g/mL.
1 lb = 453.592 g
250 lb = 113398 g
Volume of the block,
V = 25 dm× 525 mm×1.5 m
Since, 1 dm = 0.1 m, 1mm = 0.001 m
V = 2.5 m× 0.525 m× 1.5 m
V = 1.9668 m³
Also, 1 m³ = 1968000 mL
So,
density = mass/volume
density = 113398 g/1968000 mL
= 0.057 g/mL
So, the density of a rectangular metal is 0.057 g/mL.
How do conduction and convection differ? (4 points)
Conduction can move through empty space to transfer heat; convection cannot.
Conduction does not require objects to have direct physical contact; convection does.
Conduction requires objects to have direct physical contact; convection does not.
Conduction transmits heat through electromagnetic waves; convection does not. PLS HELP
Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas.
So I think you should go with the 3rd option.

Explanation:
All matter has thermal energy because atoms are constantly
All matter has thermal energy because atoms are constantly in motion, due to motion all matter possess a kinetic energy. The total kinetic energy is known as thermal energy.
What is kinetic energy?The kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes
Thermal energy and temperature are closely related. Both reflect the kinetic energy of moving particles of matter. However, temperature is the average kinetic energy of particles of matter, whereas thermal energy is the total kinetic energy of particles of matter.
It increases or decreases only when the velocity changes, heavier objects, It can transform into other types of energy. It will occur regardless of the moving object's direction of travel.
Thus, all matters has thermal energy because atoms are constantly in motion.

Calculate the mass of a sample of fruit sugar, fructose,
C6H1206, containing 2.65 X 1020 molecules.
Answer:
, containing 2.65 X 1020 molecules.
Explanation:
The mass of a sample of fruit sugar (fructose) C₆H₁₂O₆, containing 2.65 ×10²⁰ is equal to 2.88 g.
What is Avogadro's number?Avogadro’s number can be defined as the number of units in one mole of any chemical substance. Generally, these entities can be electrons, molecules, atoms, ions, or protons, depending upon the kind of chemical reaction or reactants and products.
The value of Avogadro’s constant is found approximately 6.022 × 10²³ mol⁻¹.
Given, the number of molecules of fructose = 2.65 ×10²⁰
The molar mass of the fructose = 180.16 g/mol
So 6.022 × 10²³ molecules of fructose have mass = 180.16 g
Then 2.65 × 10²⁰ fructose molecules will have mass = 2875.04 × 10⁻³ g
The mass of the 2.65 × 10²⁰ fructose molecules = 2.88 g
Therefore, the mass of 2.65 × 10²⁰ fructose molecules is equal to 2.88 g.

What does Newton’s first law of motion state?
Answer:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... If that velocity is zero, then the object remains at rest.
Explanation:
Answer:
Before Galileo and Newton, many people thought that objects lost speed because they had a built-in natural tendency to do so. But those people weren't taking into account the multiple forces here on Earth - for example, friction, gravity, and air resistance - that cause objects to change their speed. If we could see the motion of an object in deep interstellar space, we would be able to observe the natural tendencies of an object that is free from any external influence. In deep interstellar space we would observe that if an object had a speed, it would continue to move with that speed until there was some force causing a change in its motion. Likewise, if an object were at rest in interstellar space, it would remain at rest until there was a force causing a change in its motion.
