Sir Isaac Newton laid the foundations for the creation of modern calculus through his work in the field of mathematics. His discovery of formulas that could be used to derive the areas of curved objects led to many of the mathematical breakthroughs of the last two centuries. He also helped in the field of science by discovering laws such as the universal gravitation law.
The electrostatic force acting on a charge q is given by
where E is the electric field's intensity.
In our problem, the particle is an electron, so its charge is
. We know the intensity of the force, so we can find the magnitude of the electric field at the point where the electron is located:
where the negative sign means that the force and the electric field have opposite direction, because the charge is negative.
Answer:
B
Explanation:
Sunlight comes in the form of light energy. Upon striking the solar panels, it converts the light energy into electrical energy so as to run throughout the circuits. Then since it's used to power light, the electrical energy will be converted back into light energy
<u>Answer:</u>
Speed of Hawk's shadow on the level ground = 3.29 m/s
<u>Explanation:</u>
When the sun is directly above the head of hawk shadow will be directly below hawk. So the speed of hawk's shadow will be equal to speed of hawk's in X -direction.
Velocity of hawk = 5.35 m/s
Angle from horizontal = 52.00⁰
Horizontal component = 5.35 cos 52.00⁰ = 3.29 m/s
So speed of hawk's shadow = 3.29 m/s
This is the order of the spectrum from highest frequency to lowest frequency:
Gamma Ray (Highest energy em wave)
X Ray (Used in medical imaging)
Ultra violet (dangerous to human skin)
visible light (human eye can see)
Infrared (medium frequency)
Microwave (used to heat food)
Radio (longest wavelength)
