Blank #1: hypothesis
Blank #2: experiment
Complete statement: "When a hypothesis is proven wrong, scientists often begin by revising the hypothesis. After that, it's common for scientists to redesign the experiment."
Answer:
television
Explanation:
a television refracts light (the light bounces off of the screen
At an altitude of 6,500 feet MSL and with the current altimeter setting is 30. 42" Hg. the pressure altitude is mathematically given as
PA=6500ft
<h3>What is the p
ressure altitude?</h3>
Generally, the equation for the Pressure altitude is mathematically given as
PA = ( 29.92 - AltSet ) * 1000 + FieldElev.
Therefore
PA= (29,92 - 30.42) * 1000 + 6,500
PA=6000ft
In conclusion, pressure altitude
PA=6500ft

The force between the planets will not change after doubling the masses of the planets and distance between them.
To find the answer, we need to know about the gravitational force of attraction.
<h3>What's the gravitational force attraction?</h3>
- According to Newton's gravitational law, the force between two objects is directly proportional to the product of their masses and inversely propertional to the square of the distance between them.
- Mathematically, Gravitational force= GMm/r². G is the gravitational constant.
<h3>What is the gravitational force between two planets when their masses and distance between them are doubled?</h3>
- Then masses are 2M and 2m. Distance is 2r.
- So gravitational force= G×2M×2m/(2r)²
= GMm/r²
Thus, we can conclude that the gravitational force will not change of the masses are doubled and the separation is also doubled between the planets.
