As light from a star spreads out and weakens, do gaps form between the photons?

Answers

Answer 1
Answer: there are no gaps in space. the light from the star weekend as it travels, but it just reduces the strength and doesn’t produce gaps.

Dua buah vektor, yaitu P= 6i-5j+2k dan Q = 2i+2j+8k. Tentukan vektor R agar P-Q+R=0. Hitung pula besar vektor R?

Answers

As it is given to us

P = 6i - 5j + 2k

Q = 2i + 2j + 8k

also it is given that

P - Q + R = 0

so here we can rearrange it to find the value of R

R = Q - P

so here we have

R = (2i + 2j + 8k) - (6i - 5j + 2k)

R = -4\hat i + 7\hat j + 6\hat k

so the vector is given by above equation


Answer:

R= -4 i + 7 j + 6 k

Explanation:

Being P - Q + R = 0, solving for R you get:

R= Q - P

You know:

  • P=6 i - 5 j + 2 k
  • Q=2 i + 2 j + 8 k

Replacing the expressions of P and Q you get:

R= (2 i + 2 j + 8 k) - (6 i - 5 j + 2 k)

i, j and k indicate that the values ​​correspond to the x, y and z components respectively. To subtract the vectors, their respective components are subtracted from each vector. So in this case:

R= (2-6) i + [2-(-5)] j + (8-2) k

So the answer is:

R= -4 i + 7 j + 6 k

The air you breathe is made of 21% oxygen and 78% nitrogen. The oxygen in air is the _____ and the nitrogen is the _____. solution, solute solute, solvent solvent, solution

Answers

solute, solvent.

Solute is what is dissolved in the solvent. Since there is less oxygen and more nitrogen, the oxygen is the solute and the nitrogen the solvent. Solution is not included in the answer because the air is the solution (the combination of the solutes and solvent).
None of the choices is correct.
Air is a mixture, NOT a solution.
There are no solvents or solutes in a mixture.

A sled is moving at a constant speed down a surface inclined at 45.0° with the horizontal and travels 30 meters in 4 seconds. Calculate the vertical velocity of the sled at the end of 4 seconds. A) 5.3 meters/second B) 4.3 meters/second C) 9.8 meters/second D) 2.3 meters/second

Answers

Answer:

Option A is the correct answer.

Explanation:

Velocity of sled can be calculated by dividing displacement to time.

Displacement = 30 m

Time = 4s

\texttt{Velocity, v = }(30)/(4)=7.5m/s

Vertical velocity component is vsinθ

Vertical velocity = vsinθ = 7.5 x sin 45 = 5.3 m/s

Option A is the correct answer.

A sled is moving at a constant speed down a surface inclined at 45.0° with the horizontal and travels 30 meters in 4 seconds. Calculate the vertical velocity of the sled at the end of 4 seconds.The answr is letter D. 2.3 meters per second

The unit of electric potential or electromotive force is the _____.volt
ohm
ampere
franklin

Answers

VOLT is the unit of electric potential or electromotiveforce. The term volt is used to honour an Italian physicist who invented thevoltaic pile, Alessandro Volta. 

Volt is a measure of electric potential. Electric potential,a type  of potential energy that could bereleased if electric current is allowed to flow. 

Its formulas would be: 
V = potential energy / charge
V = N * m / coulomb
V = kg * m * m / s² * A * s = kg * m² / A * s³
V = A * Ω
V = W / A
V = J / C
V = eV / e 

ohm (Ω) is the unit of electrical resistance. 
ampere (A) is the unit for measuring the strength of an electriccurrent 
watt (W) is the unit of electrical power



the unit of electromotive force  is volt
