Suppose Earth’s gravitational force were decreased by half. How would this change affect a game of basketball? Think about the motion of the players and the ball.

Answers

Answer 1

Answer:

Due to the decrease in the gravitational force, it will take longer time for ball to reach the ground while dribbling. Moreover, the hang time of players will also be longer. This means that the players will stay on air longer and will be able to jump higher.

how is energy transfered from one piece of metal to another

Answers

Answer:

The positive and negative electrons attract leaving a shock and heat travels faster through metal than any other material such as plastic, wood, etc.

Explanation:

Answer:

The electrons in a piece of metal can leave their atoms and move about in the metal as free electrons. ... The hotter the metal, the more kinetic energy these vibrations have. This kinetic energy is transferred from hot parts of the metal to cooler parts by the free electrons.

Which equation is NOT balanced?
A. 2H2 + O2® 2H2O
B. H2 + H2 + O2® H2O + H2O
C. 2H2 + O2® H2O
D. 4H2 + 2O2® 4H2O

Answers

Answer:

C

Explanation

On the reactants side there is 4 Hydrogen atoms in total and two oxygen atoms on the left however on the right there is two hydrogen atoms and one oxygen atom. Leaving this equation unbalanced

The equation that is NOT balanced is [tex]\rm 2H_2 + O_2\rightarrow H_2O[/tex]. The correct answer is option C.

In a balanced chemical equation, the number of atoms of each element on the reactant side must be equal to the number of atoms of each element on the product side.

In equation A, there are 4 hydrogen atoms and 2 oxygen atoms on both the reactant and product sides, so it is balanced.In equation B, there are 4 hydrogen atoms and 2 oxygen atoms on both the reactant and product sides, so it is balanced.In equation C, there are 4 hydrogen atoms and 2 oxygen atoms on the reactant side, but only 2 hydrogen atoms and 1 oxygen atoms on the product side. Therefore, it is not balanced.In equation D, there are 8 hydrogen atoms and 4 oxygen atoms on both the reactant and product sides, so it is balanced.

In conclusion, equation C.  [tex]\rm 2H_2 + O_2\rightarrow H_2O[/tex] is the one that is NOT balanced. It has an unequal number of oxygen atoms on the reactant and product sides.

Radio waves are used to transmit information on various channels. What is the wavelength of a radio wave having the frequency of 5.40 × 1010 Hz?

1. Analyze the Problem

ν = and c = Unknown: λ =

You know that because radio waves are part of the electromagnetic spectrum, their speed, frequency, and wavelength are related by the formula c = λν.

Answers

Answer:

5.56×10¯³ m

Explanation:

From the question given above, the following data were obtained:

Frequency (v) = 5.4×10¹⁰ Hz

Wavelength (λ) =?

The velocity of electromagnetic wave, frequency and wavelength are related according to the equation:

Velocity (c) = wavelength (λ) × frequency (v)

c = λv

With the above formula, the wavelength of the radio wave can be obtained as follow:

Frequency (v) = 5.4×10¹⁰ Hz

Wavelength (λ) =?

Velocity (c) = 3×10⁸ m/s

c = λv

3×10⁸ = λ × 5.4×10¹⁰

Divide both side by 5.4×10¹⁰

λ = 3×10⁸ / 5.4×10¹⁰

λ = 5.56×10¯³ m

Thus, wavelength of the radio wave is 5.56×10¯³ m

I took the test it’s PROTONS

Answers

Answer:

Protons

Explanation:

Typically protons cannot be removed from the atom. Removing protons from an atom will completely change the atom as it will become another element entirely.

In an atom, protons are held by strong nuclear forces.

Within an atom, protons are the positively charged particles. Together with the neutrons, they are found in the nucleus of an atom. The number of protons within an atom is the atomic number of the atoms and it determines the nature and type of atom it is. Protons cannot be removed from an atom due to the strong binding force holding them together in place.

115 mL of a 2.35 M potassium
fluoride (KF) solution is diluted with 1.28 L of water. What is the new concentration in molarity?
? M KF

Answers

The new concentration : = 0.194 M

Further explanation

Given

115 mL(0.115 L) of a 2.35 M Potassium  fluoride (KF)

1.28 L of water

Required

The new concentration

Solution

Dilution is the process of adding solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

Can be formulated :

M₁V₁=M₂V₂  

M₁ = Molarity of the solution before dilution  

V₁ = volume of the solution before dilution  

M₂ = Molarity of the solution after dilution  

V₂ = volume of the solution after dilution

V₂=0.115 + 1.28 = 1.395 L

Input the value :

M₂ = (M₁V₁)/V₂

M₂ = (2.35 x 0.115)/1.395

M₂ = 0.194

Answer: 0.194

Answer:

From my side the correct option is "A"

Explanation:    Reasons for its correction are ,

1)  Highly reactive: Nanoparticles are therefore extremely unstable and easily change themselves or react with active substances to reach a relatively stable state in some cases. This causes desired changes or undesired changes to nanoparticles and thus makes them exhibit a high reactivity and a poor stability.

2)Small size:  Nanotechnology can provide rapid and sensitive detection of cancer-related molecules, enabling scientists to detect molecular changes even when they occur only in a small percentage of cells. Nanotechnology also has the potential to generate entirely novel and highly effective therapeutic agents.

A 2.5 L container holds a sample of hydrogen gas at 291 K and 180 kPa.

If the pressure increases to 350 kPa and the volume remains constant, what will the new temperature be?

Round your answer to one decimal place.

Answers

Answer:

The new temperature will be 565.83 K.

Explanation:

Gay Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant. This law says that the pressure of the gas is directly proportional to its temperature. This means that if the temperature increases, the pressure will increase; or if the temperature decreases, the pressure will decrease.

In other words, Gay-Lussac's law states that when a gas undergoes a constant volume transformation, the ratio of the pressure exerted by the gas temperature remains constant:

[tex]\frac{P}{T} =k[/tex]

When an ideal gas goes from a state 1 to a state 2, it is true:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

P1= 180 kPaT1= 291 KP2= 350 kPaT2= ?

Replacing:

[tex]\frac{180 kPa}{291 K} =\frac{350 kPa}{T2}[/tex]

Solving:

[tex]T2=350 kPa*\frac{291 K}{180 kPa}[/tex]

T2= 565.83 K

The new temperature will be 565.83 K.
