The diagram below show the alignment of the sun moon and earth
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.

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

An object's speed is 0.8 m/s, and its momentum is 200 kg-m/s What is the mass of the object?
A. 250kg
B. 200kg
C.160kg
D.128kg
Answer:
A: The mass would be 250kg
Explanation:
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity.
p= mv
m= p/ v
The explanation to that is:
momentum = mass× velocity
mass= momentum / velocity
THE ANSWER IS A
Hope this helps!
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.

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.

what is vector product B×A of two vectors A=7i+4j-8k and B=3i-3j+5k
Answer:
[tex]4i+59j+33k[/tex]
Explanation:
Given that,
Vector A = 7i+4j-8k
vector B = 3i-3j+5k
We need to find B×A. It can be calculated as follows :
[tex]B\times A=(3i-3j+5k)\times (7i+4j-8k)\\\\=i (24 - 20) - j (-24 - 35) + k (12 + 21) \\\\=4i+59j+33k[/tex]
So, the value of vector product is [tex]4i+59j+33k[/tex].

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
