Answer: A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs when a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment. The size and shape of a delta is controlled by the balance between watershed processes that supply sediment.

maxonik [38]

Answer:

∆U = 2.296×10^10Joules

Explanation:

Gravitational potential energy is defined as the energy possessed by an object under the influence of gravity due to its virtue of position.

Potential energy U = Fr where;

F is the force of attraction between the masses of the moon and the rocket.

r is the radius or height of the object.

From Newton's law of universal gravitation, F = GMm/r²

Potential energy U = (-GMm/r²)×r

Potential energy U = -GMm/r

The force is negative because the objects act upward.

M is the mass of the rocket

m is the mass of the moon

Gravitational potential energy possessed by the rocket

U1 = -GMm/r1

r1 is the altitude covered by the rocket

Gravitational potential energy possessed by the Moon

U2 = -GMm/(r2+r1)

r2 is the radius of the moon

Change in gravitational potential energy ∆U = U2-U1

∆U = -GMm/(r2+r1)-(-GMm/r1)

∆U = -GMm/(r2+r1) + GMm/r1

∆U = -GMm{1/(r2+r1)-1/r1}

Given

G = 6.67×10^-11m³/kgs²

M = 1130kg

m = 7.36×10²²kg

r1 = 215km = 215,000m

r2 = 1740km = 1,740,000m

∆U = -6.67×10^-11× 7.36×10²² × 1130{1/(215,000+1,740,000)-1/215000}

∆U= -55.47×10¹⁴{1/1955000-1/215000}

∆U = -55.47×10¹⁴{5.12×10^-7 - 4.65×10^-6}

∆U = -284×10^7 + 257.94×10^8

∆U = 22,954,000,000Joules

∆U = 2.296×10^10Joules

describe three small changes that you can make to your current eating habits to support a healthier lifestyle.
Drupady [299]

Answer:   Eat only when you're truly hungry instead of when you are tired, anxious, or feeling an emotion besides hunger.

Plan meals ahead of time to ensure that you eat a healthy well-balanced meal.

Keep more fruits, low-fat dairy products (low-fat milk and low-fat yogurt), vegetables, and whole-grain foods at home and at work.

A white blood cell has a diameter of approximately 12 micrometers, or 0.012 um. A model represents its diameter as 24 um. What i
GuDViN [60]

Answer:

2:1

Explanation:

It is given that,

The diameter of a white blood cell is 12 micrometers

The diameter of white blood cell according to a model is 24 micrometers.

We need to find the ratio of model size to actual size. It can be done as follows :

R=\dfrac{\text{model size}}{\text{actual size}}\\\\R=\dfrac{24\ \mu m}{12\ \mu m}\\\\R=\dfrac{2}{1}

Hence, the ratio of model size to actual size is 2:1.

Write the equation for speed
zzz [600]

Answer:

Distance / Time = Speed

Explanation:

This is because you want to see how much distance you cover within a time interval.

For example, MPH, is a unit for speed, which is miles (distance) per hour (time)
