The time required for Mars to orbit the Sun in Earth days is 1.87y.
What is Kepler's law of periods?The square of the time period of orbiting is directly proportional to the cube of the mean distance.
The ratio of mean distance, (am /ae)³ = (Tm/Te)²
Substitute the ratio of semimajor axis and time period of earth orbit Te =1 yr, we get
(1.52)³ = (Tm / 1 yr)
Tm=1.87y.
Thus, the time required for Mars to orbit the Sun in Earth days is 1.87y.

Newton's first law states that objects do not change their velocity unless acted upon
by an outside force. When throwing a ball the ball initially accelerates from the force
provided by your arm and then begins to slow down.
What force(s) are responsible for the deceleration of the ball?
Answer:
Air resistance/Drag (this is the proper term for air resistance) or gravity or friction
It depends on the direction and if you throw it across a surface or if you throw it straight upwards.
I hope this helps!!
Answer:
Newton's first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.

is it true that the radiation that transfer thermal energy is a type of electromagnetic radiation
Answer:
Since heat is carried by electromagnetic waves, it does not need a physical medium to transfer it. Instead it radiates through space - this is how the Earth is heated by the Sun despite space being a vacuum.
Explanation:

Why is the air temperature shown on Sensor 4 different from Sensor 5, even though they are at the same latitude?
Answer:
Hello your question lacks some information but i will give you a more General answer about differences in temperature of bodies on same latitude
answer : Continentality is the reason
Explanation:
Sensors or objects on the same latitude are supposed to have the same air temperatures but in some cases this might not be true. This is because of the proximity of the bodies to an Ocean or any water body.
Areas close to water bodies experience modest temperatures even if they are on the same latitude with Areas experiencing harsh temperatures. This effect is termed as Continentality

When a colid cuch as ice begins to melt heat energy is added. What is the function of this added heat
Answer:
As the phase changes occur, the freedom of motion of the particles increases
Explanation:
In thermodynamics the state of matter: solid, liquid and gaseous.
We can characterize them, the solid state maintains a certain shape, which is why particles are tightly bound and can hardly move from their equilibrium positions.
The liquid state does not hold its shape, so the particles have more energy and can move a lot from their equilibrium position.
The gaseous state does not maintain the shape or the volume, so the interaction between the particles is very small, so they can move almost freely.
When examining the answer, the correct one is: As the phase changes occur, the freedom of motion of the particles increases.

It is the disturbance or oscillation that travels through space and matter, accompanied by a transfer of energy.
Answer:
wave
Explanation:
A wave is defined as the disturbance that causes the movement of energy. The energy is transferred as the waves move from one place to another. A medium is required for the transfer of energy. Usually a wave travels through air or water. The process is carried on at a specific speed that is termed as the speed of propagation.

A stone of mass 0.2kg is thrown vertically upwards from the ground with a velocity of 20m/s. Find the maximum height attained by the stone
Answer: 20.4 m
Explanation: speed v upward is v = vo -gt.
When maximum height v = 0, vo -gt = 0 and
T = vo / g = 20 m/s / 9.81 m/s² = 2.04 s
Now height y = vot -0.5 gt^2 = 20,4 m
This is possible to solve using
Conservation of energy Ek= Ep
0.5mv² = mgh. And h = v²/2g. Results same

To drive your car from Auburn to Atlanta (173.8 km) takes a significant amount of work. Assuming the force of friction between the tires and the road is 10290 N, how much work needed to drive that far? Express your answer in megajoules (MJ).
Answer:
1788.402 MJ
Explanation:
Work done = Force (N) x distance (m)
First we have to convert distance into metres:
173.8 x 1000 = 173,800 m
Then plug these values into the equation above:
173,800 x 10290 = 1788402000 J
The reason it's Joules (the unit for energy) is because work done = energy transferred
Now we have to convert Joules into Mega Joules:
1 J = 1/1000000 MJ
1788402000 J = 1788402000/ 1000000 = 1788.402 MJ

The rhinestones in costume jewelry are glass with index of refraction 1.50. To make them more reflective, they are often coated with a layer of silicon monoxide of index of refraction 2.00. What is the minimum coating thickness needed to ensure that light of wavelength 527 nm and of perpendicular incidence will be reflected from the two surfaces of the coating with fully constructive interference
Answer:
t = 6.6 10⁻⁸ m
Explanation:
In this case we have that the reflection in the film is constructive, we take into account that
* When the light is reflected from the air (n = 1) to the film (n=2) it has a phase change of 180º
* within the film the wavelength is modulated by the index of refact
λₙ = λ₀ / n
taking into account these two aspects the expression for constructive interference is
2n t = (m + ½) λ₀
let's find the minimum thickness (t) of the film
t = (m + ½) λ₀ / 2n
for m = 0
t = ½ 527 10⁻⁹ /(2 2.00)
t = 6.6 10⁻⁸ m

Which diagram shows an alignment in which spring tide takes place
A
B
C
D
Answer:
A
Explanation:
The image that shows an alignment of earth, moon and sun during spring tide is option A. All of them will be in a straight line.
What is spring tide ?A spring tide is a type of tide that occurs when the Earth, sun, and moon are aligned in a straight line. During a spring tide, the gravitational pull of the sun and the moon combine, resulting in higher-than-normal high tides and lower-than-normal low tides.
During a spring tide, the position of the sun, moon, and earth is aligned in a straight line. The gravitational force of the moon and sun both act upon the oceans of the Earth, creating a combined effect that results in unusually high tides.
During a spring tide, the moon is either new or full, which means it is in a position that aligns with the sun and Earth. The gravitational pull of the moon and sun reinforce each other, creating a stronger gravitational force on the Earth's oceans.
This causes the water level to rise higher than normal during high tide and lower than normal during low tide. Here, image A shows the correct alignment.
