The first time we read this, we think that we'll have to go look up a bunch of stuff about the gravitational constant, centripetal force, orbital mechanics, the Moon's period of revolution, and who knows whut owl !
But you know whut ? The only thing we need is Newton's 2nd law:
F = m A
Divide each side by m :
Acceleration = Force / mass
Acceleration = (2.03 x 10²⁰ Newtons) / (7.35 x 10²² kg)
Acceleration = (2.03 x 10²⁰ / 7.35 x 10²² kg) (m/s²)
<em>Acceleration = 0.00276 m/s²</em>
Answer:
4.416 W/m²
Explanation:
Malus' law is given mathematically as
I = I₀ cos² θ
For the first polarizer, θ = 60°
I₁ = I₀ cos² 60°
I₁ = I₀ (0.5)² = 0.25I₀
For the second polarizer, θ = 20°
I₂ = I₁ cos² 20°
I₂ = I₁ (0.9397)² = 0.883 I₁
I₂ = 0.883 × 0.25I₀ = 0.2208 I₀
Note that
I₀ = 20 W/m²
I₂ = 0.2208 × 20 = 4.416 W/m²
Hope this Helps!!!
The correct answer is - C. Crustal plates, crustal plates.
The movement of the crustal plates of the Earth is the reason why the geologic processes are occurring on our planet. With their movement, the crustal plates manage to create lot of pressure, open up gaps for the magma from the mantle, as well as make adjustments deeper into the ground.
Because of the adjustments deep into the ground, or rather the crust, lot of force is released, manifested as strong and very quick vibrations, better known as earthquakes.
The gaps that are opening between the plates let the magma reach the surface, thus enabling the volcanic activities on the planet.
The pressure from the plates' collision makes the land lift up slowly, and over time a mountain range starts to form because of the continuous lifting up of the area.
Answer: B
Baking soda has unique properties. It can be used in multiple ways, like cleaning. Productive means something produces a lot of something. Baking soda does not produce anything. Baking soda does not have distinguishable properties, other things can substitute baking soda.
Hope this answer helps you!
Maybe it’s suppose to say fuel or something fossil fuel or something like that
