Answer: D
Explanation: Energy is neither created nor destroyed so the amount of reactants and products must be equal
Answer:
To verify that they're polarized, he could hold the two lenses perpendicular (90 degrees) to each other, one lens in front of the other, and point it at a light source. If no light passes through then the lenses are polarized
By the electromagnetic "vibrations" that make up light. Said EM vibrations are an electric field and a magnetic field at right angles to each other and to the direction of propagation/travel. Light travels by the same "mechanism" that X rays travel, radio waves travel and anything else in the vast electromagnetic spectrum. Probably how I'm able to type these words on a computer key board and have them transmitted "Wi Fi" like, to you, the hapless recipient. You're a Cheetah ??? That means you can run like the wind ????
Answer:
3.86×10⁶ Newton/coulombs
Explaination:
Applying,
E = F/q....................... Equation 1
Where E = Electric Field, F = Force, q = charge.
From the question,
Given: F = 5.4×10⁻¹ N, q = -1.4×10⁻⁷ coulombs
Substitute these values into equation 1
E = 5.4×10⁻¹/ -1.4×10⁻⁷
E = -3.86×10⁶ Newtons/coulombs
Hence the magnitude of the electric field created by the
negative test charge is 3.86×10⁶ Newton/coulombs
Visible light waves are the only electromagnetic waves we can see has the longest wavelength
