With the Sun and Moon in this position, the side of the earth facing the moon experiences a spring high tide. Thus Option C is the answer.
A spring tide is a tide that occurs when the gravitational pull of the Moon and the Sun are in alignment. During a new moon or full moon phase, the gravitational pull of the Moon and the Sun combine to produce stronger than normal high tides and stronger than normal low tides. The term "spring tide" does not refer to the season of spring, but rather the tide's "springing forth" of water.
During a spring tide, the difference between high tide and low tide is at its greatest, and the water level rises higher and falls lower than during a neap tide. This is because the gravitational pull of the Moon and Sun are working together to produce the tide, rather than against each other. This results in a high tide that is higher than a normal high tide, referred to as a spring high tide.
It is important to note that spring tides occur twice a month, around the time of the new and full moon, when the Moon and Sun are in alignment.

explain what an unbuckled passenger in the car experiences as the car
moves through the turn, assuming the passenger completes the turn in
the car. You must also properly explain inertia's role in this scenario *
An unbuckled passenger in the car experiences movement towards right side due to inertia as the car moves towards left.
According to Newton's first law of motion, every body continues to be in a state of rest or of uniform motion unless an external force acts upon it. This is called inertia. It is the tendency of an object to resist change.
As a result, when the car makes a sudden left turn, the passengers appear to move to the right side of the vehicle because they are still travelling in the same straight line that the car was travelling in before the turn.

If you throw a ball up in the air at a speed of 14.9 m/s, how fast (in m/s) will it be moving when you catch it
When you catch a ball you threw in the skies at the a speed exceeding 14.9 m/s, it will also travel at the same speed when you catch it.
How fast is it?Time is a scalar that indicates the direction and speed of an object's motion. Usually, it is expressed in terms of measures of speed per amount of time, including m / sec (m/s) or miles each hour (mph) (mph). Speed is the size of velocity, a vector number that indicates both the direction and the speed of motion. Pace is a positive number with a unit of distance traveled per second.
When something is launched into air, it is exposed to the downward-moving force of gravity. The item accelerates downward at a velocity of 9.8 m/s2 as a result of this force
The object will slow down so that it rises and accelerate up as it lowers due to this acceleration. However, if there is very little time between the ball's release and the catch, the ball won't have a chance to slow down much. As a result, the pace at which i catch the ball will be quite similar to the pace at which originally threw it.
The ball will therefore continue to move at the same pace that it did when thrown.

A force of 255 N is applied to an object that accelerates at a rate of 7 m/s2. What is the mass of the object?
The mass of the object is 36.43 kg.
We can use the equation for force (F) to determine the mass (m) of the object:
F = m × a
Where F is the force applied to the object, m is the mass of the object, and a is the acceleration of the object.
So, in this case, we know that:
F = 255 N
a = 7 m/s²
We can use this information to solve for the mass of the object:
m = F ÷ a
m = 255 N ÷ 7 m/s²
m = 36.43 kg
Therefore, the mass of the object is 36.43 kg.
It's important to notice that this equation only holds if the force applied is the net force, so if there are other forces such as friction or air resistance they should be considered in the calculation.

Explanation:
Given Info:
Object of mass ⇒ 1.2 kg
Velocity of 2.0m/s when it is acted on by a force of 4.0 N
Velocity of the object Increased to 5.0 m/s
Question:
For what period of time does the force act on the object?
Solve:
We first need to know the formula:
F = ma Or F = m(v-u)/t
F = force
m = mass of an object
a = acceleration
v = Final Velocity
u = Initial Velocity
a = Acceleration
t = Time Taken
Knowing that;
Force = 4.0 N
Mass of an object = 1.2 kg
Final velocity = 5.0m/s
Initial velocity = 2.0m/s

pls answer quickly
Answer:
To solve this problem, you can use the principle of transverse static equilibrium. This states that the sum of the forces acting on an object must be equal to zero for the object to be in equilibrium. In this case, the forces acting on the rod are the tension in the strings, the weight of the rod, and the weight of the masses hung on the rod.
First, you can find the weight of the rod by multiplying its mass by the acceleration due to gravity:
Wrod = mrod * g
= 0.7 kg * 9.8 m/s^2
= 6.86 N
Next, you can find the weight of the 4.0-kg mass by multiplying its mass by the acceleration due to gravity:
W1 = m1 * g
= 4.0 kg * 9.8 m/s^2
= 39.2 N
You can find the weight of the 2.0-kg mass in the same way:
W2 = m2 * g
= 2.0 kg * 9.8 m/s^2
= 19.6 N
To find the tension in the strings, you can use the principle of transverse static equilibrium. The forces acting on the rod are the tension in the strings, the weight of the rod, and the weight of the masses hung on the rod. You can represent these forces as vectors acting at the points where the strings are attached to the rod. The vectors representing the tension in the strings will be equal in magnitude but opposite in direction. The vectors representing the weight of the rod and the masses will act vertically downward.

The frequency of the oscillation is the number of cycles completed by the oscillatory object in a given second.
The frequency of the wheel undergoing oscillatory motion is calculated by using the following formula.
f = ω / 2π
where;
ω is the angular speed of the wheelf is the frequencyf = ( 2 rad/s ) / 2π
f = 0.32 Hz
The period of the oscillation is calculated as follows;
T = 1 / f
T = 1 / 0.32 s
T = 3.13 seconds
Thus, the period of oscillation and frequency of the oscillation are inversely proportional.

The human ear canal is about 2. 8 cm long and can be regarded as a tube open at one end and closed at the eardrum. What is the frequency around which we would expect hearing to be best when the speed of sound in air is 344. 5 m/s? (hint: find the fundamental frequency for the ear canal. )
The human ear canal is closed at one end. Thus, the fundamental frequency of the given ear canal is 3044.64Hz 3044.64 Hz .
Calculation and Explanation:Under air conduction (AC) excitation, the mean resonance frequency of the human middle ear is estimated to be between 0.8 and 1.2 kHz. The typical resonance frequency under bone conduction (BC) excitation, according to research, is higher, at 1.5–2 kHz.
It is a tube with an open end (the concha section) and a closed end (the tympanic membrane), which responds to a quarter-wave by behaving as a resonator. The resonance frequency is described by the equation F=v/4L, where "v" stands for the speed of sound and "L" for the length of the EAC.
The EAR formula should be used: EAR = (1+ i/n)n - 1. I = Stated interest rate, etc.
