Answer:
F/2
Explanation:
In the first case, the two charges are Q1 and Q2 and the distance between them is r. K is the Coulomb's constant
Hence;
F= KQ1Q2/r^2 ------(1)
Where the charge on Q1 is doubled and the distance separating the charges is also doubled;
F= K2Q1 Q2/(2r)^2
F2= 2KQ1Q2/4r^2 ----(2)
F2= F/2
Comparing (1) and (2)
The magnitude of force acting on each of the two particles is;
F= F/2

1 BTU mean 1 degree of F increased for 1 pound mass. Since the mass unit is in kg that means you need to convert it into pound. One metric ton means 1000kg and 1 kg mean 2.20462lb, then the water mass is: 1000kg x 2.20462lb/kg= 2204.62lb.
You are putting 110,000 btus of heat, so the calculation would be
Temperature increase= energy/mass = 110000btus/ 2204.62lb= 49.9 degree
Answer:
Newton's third law of motion says that for every action there is an equal and opposite reaction.
Explanation:
This law explains that when two bodies interact with one another, two forces facilitates this process.These forces are opposite is action but equal in magnitude.For example, when sitting on a coach, the body exerts force on the coach downwards and the coach exerts an upward force on the body.These two forces are the action and reaction forces.
Answer: D.ultraviolet rays, visible light, infrared radiation, microwaves.
Explanation:
Shorter wavelength means higher frequency and higher energy.
Thus, the correct sequence of electromagnetic waves from shorter wavelength to longer wavelength is:
D.ultraviolet rays, visible light, infrared radiation, microwaves.
<u>Ultraviolet rays have shorter wavelength (about 380 nm) and high energy. </u>
<u>Visible light has wavelength: 380 nm to 700 nm</u>
<u>Infrared wavelength: 700 nm to 1 mm</u>
<u>Microwave wavelength: 1 mm to 1 m</u>
