hello your question is incomplete below is the complete question

Sheila lives in the seashore community of Beachview. At 6:00 a.m. one morning, she noticed that the local ocean water was at high tide. At approximately noon that same day, she noticed the water was at low tide.

Which of the following describes what caused the change in tides between 6:00 a.m. and noon that day

options :  

A)The Earth revolved approximately 90° around the Sun, and the gravitational attraction between the Moon and Sun increased.

B)The Earth completed one full rotation (360°), and the gravitational attraction between the Moon and the Beachview area increased.

C)The Earth completed one full revolution around the Sun (360°), and the gravitational attraction between the Moon and Sun decreased.

D)The Earth rotated approximately 90°, and the gravitational attraction between the Moon and the Beachview area decreased.

answer :  

The Earth rotated approximately 90°, and the gravitational attraction between the Moon and the Beachview area decreased.  ( D )

Explanation:

The movement of the Earth in the Galaxy occurs in two ways

namely: Rotation and Revolution and each movement comes has an effect on the earth, also each movement has a time frame as well.

The complete rotation of the earth about its axis takes about 24 hours and this rotation brings about Night and day and it also causes the rise and fall of tides. while the Revolution of the earth round brings about different seasons and it takes about 365 days for a complete revolution of the earth round the sun.

hence the the change in tides between 6:00 a.m. and noon that day is caused by The Earth rotating approximately 90°, and the gravitational attraction between the Moon and the Beachview area decreased.

Answer:

In order to convert density to grams, you have to put the mass on one side of the equation, and the density and the volume on the other. Therefore, d * v = m. Multiply the density by the volume. Using the example in step 1, you would multiply 2 g/mL by 4mL.

1. Force is something that pushes or pulls you

2. The 150 lbs person accelerated faster because they had less force pushing or pulling them down.

What is the “price” that you pay for using less force? The price that you pay for using less force is having to do more work.

.....................................

dont ask this is what i looked up and found

The "price" that you pay for using less force is:

Force is defined as the energy which is required to move or change the velocity of an object.

There are different types of force which includes:

As a result of this, if there is less force exerted on an object, then the "price" which would be paid for this is that the object would not move.

Answer:

A: Air pressure decreases as air density increases

Explanation:

Pressure is a force exerted on or against an object by being in contact with a substance. Thus, air pressure is due to the bombardment of the air (gas) particles with a surface. Density is defined as the mass per volume of a substance. Thus, air density is defined as the mass of air per unit volume.

If that Explanation does not make any sense let me make it easier.

The air at the top of a mountain is cooler than the air at the bottom. This temperature difference is due to a phenomenon that occurs in Earth’s atmosphere. Air rises and sinks based on differences in temperature and pressure. Here’s a quick experiment that will help explain the role of pressure.Take in a deep breath as if you were ready to blow out birthday candles. Puff your cheeks with air like a chipmunk. Hold it for a few seconds, and then blow the air slowly from your cheeks.Cold air sinks while warm air rises because cold air is denser than warm air. When a lot of cold air sinks, it creates an area of high air pressure where it hits the surface. This high-pressure air flows to an area of low pressure, creating wind. When this air warms, it rises up into the atmosphere.Temperature decreases as altitude increases. That’s why a mountain peak may be covered with snow while the bottom of the mountain is full of green plants and trees. When warm air rises into the atmosphere, it cools. The density of the air increases as it cools, which eventually creates an area of high pressure and starts the cycle again.

If not for this phenomenon of air rising and sinking in the atmosphere, there would be no wind or weather.

Answer:

v = 0.713[m/s]

Explanation:

Kinetic energy is defined as the product of mass by the squared velocity of a body. In this way with the following expression we can have the kinetic energy as a function of velocity.

[tex]E_{kin}=0.5*m*v^{2}[/tex]

where:

m = mass = 85 [kg]

v = velocity [m/s]

Ekin = kinetic energy = 2.16*10 [J]

[tex]2.16*10 = 0.5*85*v^{2}\\v =\sqrt{0.508} \\v= 0.713[m/s][/tex]

The answer is kinetic energy

Explation: it is moving

In gym class, a student kicks a soccer ball high into the air. As the ball goes upward, the gravitational potential energy gets increased.

What is Gravitational potential energy?

Gravitational potential energy can be defined as if the energy of an object possesses because of its position in a gravitational field.

The formula for gravitational potential energy is,

U = mgh

where,

U - Gravitational potential energy,

m - Mass,

g - gravitation field,

h - Height.

As we are on the Earth, the gravity acceleration can be as constant and the value is a = 9.8 m/s².

As a student  kicks the ball, first it moves upward and its gravitational potential energy is increases and kinetic energy will completely begins to decrease but when the ball falls towards the earth, its gravitational potential energy will be transformed into kinetic energy. When the ball collides with the ground, the kinetic energy is transformed into other forms of energy.

The kinetic energy and gravitational potential energy changes during its movement from ground to the top height. Thus, when the ball goes upward gravitational potential energy gets increased.

Answer:

they have same acceleration 2m/s^2

Explanation:

a =v-u/t

65-60/2.5

2m/s^2

a) The acceleration of the car and the bicycle are equal since [tex]\delta V[/tex] for both vehicle is 5km/h and the time taken for both vehicle is also the same 2.5s.

b) The acceleration of the bicycle is 0.556m/s²

Given the data in the question;

Since the bicycle starts from rest

a)

The acceleration of the car and the bicycle are equal since [tex]\delta V[/tex] for both vehicle is 5km/h time taken for both vehicle is also the same 2.5s.

b)

The acceleration of each vehicle

To determine the acceleration for car and the bicycle, we use the first equation of motion:

[tex]v = u + at[/tex]

Where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time.

Now, For the car;

[tex]18.0556m/s = 16.667m/s + ( a + 2.5s )\\\\a = \frac{18.0556m/s - 16.667m/s }{2.5} \\\\a = \frac{1.3886m/s}{2.5s} \\\\a = 0.556 m/s^2[/tex]

Hence, the acceleration of the car is 0.556m/s²

For the bicycle;

[tex]1.38889m/s = 0 + ( a * 2.5s )\\\\a = \frac{1.38889m/s}{2.5s}\\\\a = 0.556m/s[/tex]

Hence, the acceleration of the bicycle is 0.556m/s²

                "relationship between drag force and driving force​"

The velocity at any time during the flight depends on the corresponding acceleration of the vehicle and the balance of forces acting of the vehicle.Forces acceleration and velocity are all vector quantities having both a magnitude and a direction.When describing the motion of an object caused by forces,one must account for both the magnitude and direction.The forces present during coasting flights are the drag and the weight.The weight is constant is magnitude and is always directed toward the center of earth.The magnitude of the drag change the square of the velocity.During ascent the drag is in the same direction as the weight .But during descent the drag opposes the weight.

For the descending rocket the next vertical external force  F is equal to the difference between the drag D and the weight W:

                  F=D-W
