What effect does Earth’s spherical shape have on the amount of sunlight that reaches the equator?

2 answers:

6 0

Because the Earth is a sphere, the surface gets much more intense sunlight, hence heat, at the equatorthan at the poles.

<h2>Answer with Explanation </h2>

The reason of this is because the shape of the Earth is spherical, this causes the Earth’s surface to get struck by the sun’s rays at different angles, creating different variants in temperatures on Earth. A perpendicular (90 degrees) angle to the Earth is formed when the equator receives intense sunlight directly as compared to the poles. At the poles, upto period of 24 hours.

What is the difference between mass and height?

PtichkaEL [24]

Well for one:

mass: mass is a property of a physical body. It is the measure of an object's resistance to acceleration when a force is applied. It also determines the strength of its mutual gravitational attraction to other bodies.

height: is a measurement from top to bottom

so for an example: my height is 5'3" and my resistance is maybe 100lb

Sodium lamps give off light at

Ratling [72]

Answer:

θ = 17.67°

Explanation:

The grating equation can be used here to find the angle. The grating equation is given as follows:

$m\lambda = dSin\ \theta$

where,

m = order = 2

d = 3.88 x 10⁻⁶ m

λ = wavelength of light = 589 nm = 5.89 x 10⁻⁷ m

θ = angle = ?

Therefore, using these values in the equation, we get:

$(2)(5.89\ x\ 10^{-7}\ m) = (3.88\ x\ 10^{-6}\ m)Sin\theta \\Sin\theta = \frac{(2)(5.89\ x\ 10^{-7}\ m)}{(3.88\ x\ 10^{-6}\ m)}\\\\\theta = Sin^{-1}(0.3036)$

θ = 17.67°

A 78−kg skier is sliding down a ski slope at a constant velocity. The slope makes an angle of 21° above the horizontal direction

Feliz [49]

Answer:

274N 0.41

Explanation:

As he is sliding down in a constant speed then the force that accelerates him (weight) and the force that slows his down (friction) are equal.

then

friction=mass x gravity x sin(21)

Fr=78kg x 9.8m/s2 x sin(21)=274N

friction= coefficient of kinetic friction x normal force of from the slope

Fr= u x 78kg x 9.8m/s2 x cos(21)=274N

Fr= u x 78kg x 9.8m/s2 x cos(21)=274Nu=274/677=0.41

What force is left out of the Quantum Mechanics theory?

nirvana33 [79]

Answer:

Quantum mechanics is a key hypothesis in material science that gives a portrayal of the actual properties of nature at the size of iotas and subatomic particles. It is the establishment of all quantum physical science including quantum science, quantum field hypothesis, quantum innovation, and quantum data science.

Explanation:

It is the greatest of issues, it is the littlest of issues. At present physicists have two separate rule books clarifying how nature functions. There is general relativity, which perfectly represents gravity and everything it overwhelms: circling planets, impacting worlds, the elements of the growing universe all in all. That is enormous. At that point there is quantum mechanics, which handles the other three powers – electromagnetism and the two atomic powers. Quantum hypothesis is very proficient at portraying what happens when a uranium molecule rots, or when singular particles of light hit a sun based cell. That is little.
