which of the following best describes bedded gypsum and halite? a. varieties of coal b. varieties of calcium carbonate evaporites; c. chemical sedimentary rocks d. detrital sedimentary rocks

Due to the gravitational pull of Earth, large tides were produced when moon was molten and going through chemical differentiation.

So there is a reason why the moon always keeping the same face toward Earth.

The simpler answer is that it rotates on its axis in about the same amount of time as it takes for the moon to orbit the Earth, or about 27 days.

The complex answer is that the gravity of the moon that changes the Earth generates tides that is also called "tidal locking". The moon is being pulled toward us by Earth (creating a rocky bulge) and is now in "synchronous rotation," which means that it spins once for each orbit around Earth due to the constant pull of Earth's gravity.

To sum up, moon rotates slowly and always faces Earth as a result of the friction produced by Earth's gravity.

The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years.

Also, the period of a wave is the amount of time it takes for a wave to complete one wave cycle or wavelength.

From the given parameter, the coil rotates 10 times in one second. The period of the coil is calculated as;

Period = 1 s / 10

Answer:

The magnitude of swing's tension is 0.71 N.

Explanation:

Given;

mass of the ball, m = 18 g = 0.018 kg

angular speed of the ball, ω = 1 rev/s

radius of the motion, r = 1 m

Angular speed in rad/s is calculated as follows;

\(\omega = \frac{2\pi \ rad}{rev} \times \frac{1 \ rev}{s} \\\\\omega = 2 \pi \ rad/s\)

Linear speed of the ball, v;

v = ωr

v = 2π x 1

v = 2π  m/s

The magnitude of swing's tension is calculated as the centripetal force keeping the ball in circular motion.

\(F_c =T = \frac{mv^2}{r} \\\\T= \frac{0.018 \ \times (2\pi )^2}{1} \\\\T = 0.71 \ N\)

Therefore, the magnitude of swing's tension is 0.71 N.

Answer:

T is less than or equal to 19 N

The speed of water at the end of spillway is 58.5 (m/s)

Calculation:

According to the Bernoulli equation:

P/x + v^2/2 + gz = constant

The initial vertical height of 175 m

However, the atmospheric pressure and density are essentially the same at the peak and bottom of the falls. Therefore,

v^2/2 + gz = constant , so:

v_bottom^2/ 2 = v_top^2/2 + gz, or:

v_bottom = √(v_top^2 + 2gz) = √(v_top^2 + 2g*175)

If v_top ≈ 0, then:

v_bottom = √(2gz) = √(2*9.8*175) = 58.5  (m/s)

What is the flow rate of water?

The amount of water that might theoretically flow out of your kitchen faucet or bathtub each minute is measured by your water flow rate, sometimes referred to as the gallons per minute (GPM). the flow rate is affected by a number of variables, but the household size is the most important one.

Therefore,  the highest possible speed of the water at the end of the spillway is 58.5m/s

Correlation is a measure of the linear relationship between two variables. It indicates the degree to which a change in one variable is associated with a change in the other variable.

Correlation does not necessarily imply causation, meaning that just because two variables are correlated does not mean that one variable caused the other to change.

There are a few reasons for this. First, correlation does not indicate the direction of the relationship. For example, two variables could be positively correlated (increase together) or negatively correlated (one increases while the other decreases), but correlation alone does not indicate which is the case.

Second, there may be third variables that are affecting both of the variables being correlated. For example, a study might find that ice cream sales are positively correlated with shark attacks.

However, this does not mean that eating ice cream causes people to be attacked by sharks, or that sharks attack more when people are eating ice cream. Instead, the third variable is likely temperature.

On hot days, people are more likely to buy ice cream and more likely to go swimming, which leads to more shark attacks.

In summary, correlation does not necessarily imply causation and other methods, such as experiments, are needed to establish causal relationships.

Explanation:

Biomass is the total quantity or weight of organisms  in a given area or volume.

When the Earth was primarily liquid, it separated into layers. The density of Earth's different layers may be predicted. For instance, it is assumed that the outermost layer, or crust, is less dense than the inner layers.

The Earth's crust is mostly composed of silicates (such as quartz, feldspar, and mica) and rocks, which are less dense than the mantle, core, or outer core.

The mantle is composed of solid rock, which is denser than the Earth's crust.

The core is the most dense layer, and it is composed of a liquid outer core and a solid inner core.

Most of the Earth's layers are composed of different types of rock and minerals.

The layers were formed from the molten material that cooled and solidified.

The Earth's layers are divided into four groups, or spheres, that represent different levels of density.

The lithosphere is the outermost layer, which includes the crust and upper mantle.

The asthenosphere is the soft layer beneath the lithosphere.

The mantle is a solid layer that surrounds the core.

The core is the Earth's central layer, consisting of a liquid outer core and a solid inner core.

The bowling ball experiences the greater magnitude impulse during the collision since it is initially at rest and is given the momentum of the small ball which has a speed of 5m/s.

The impulse of the bowling ball can be calculated using the equation impulse = change in momentum = mvf - mvi, where m is the mass of the bowling ball, vf is its final velocity, and vi is its initial velocity.

Since the bowling ball is initially at rest (vi = 0), the impulse can be calculated as mvf = m(5m/s) = 5m^2/s. The impulse of the small ball can be calculated in the same way, giving an impulse of 5m^2/s. Therefore, the bowling ball experiences a greater magnitude impulse during the collision.

Yes, Admiralty Head does have mixed tides.

Mixed tides are characterized by two high tides and two low tides of different heights each day. This occurs in locations where the gravitational pull of the moon and sun have a stronger influence on the tides, such as at Admiralty Head.

In general, tides are caused by the gravitational pull of the moon and sun on the Earth's oceans. The moon has a stronger influence on tides due to its closer proximity to Earth. However, the sun's gravitational pull also plays a role in the formation of tides.

At Admiralty Head, the mixed tides occur because the moon's gravitational pull is stronger on one side of the Earth than the other, causing the two high tides and two low tides to be of different heights. This creates a unique tidal pattern that is characteristic of Admiralty Head.

In conclusion, Admiralty Head does have mixed tides due to the stronger influence of the moon and sun's gravitational pull on the tides in this location.

  The centre of mass of the system is the point at which the total

  mass of system could be concentrated without changing the moment

  of the system.

Centre of Mass is the point at which the whole mass of the system

is assumed to be concentrated.

 The general formula for the COM is:

              xₙ =  Σmₐxₐ / Σmₐ         where,  a = 1,2,3.........n

  Here the term Σ mₐ xₐ is called the first moment of the system and the

  denominator expression is called total mass of the system.

    Therefore, from this theory we can say that the moment of the system

    remain unchanged while calculating the COM.

  Hence, The centre of mass of the system is the point at which the total

We can presume that an ambulance with its siren activated is rushing to get somewhere and, depending on the driving circumstances, is likely travelling between 30 and 150 km/h. The vehicle's speed can be determined using the Doppler effect equation. Let va represent the ambulance's maximum speed. The frequency, f'=(vvv a)f=560Hz, is audible as it gets closer.

Because the source is travelling in the direction of the observer, a negative sign appears. The ambulance is described as moving away by the opposite sign with source velocity magnitude. The Doppler shifted frequency as it recedes is f')=(vv+v0)f=480Hz.

The speed of the source can be calculated as va=v(f'f')f'+f'=(343ms)(560Hz480Hz)560Hz+480Hz=26.4ms by solving the second of these equations for f and substituting into the other.
