Answer:
Explanation:
Lithification is the process by which sediments compact under the influence of pressure and the sediments become rocks. This process limits the porosity by destruction of porosity by compaction and cementation.
Sandstone is clastic sedimentary rock that forms by the process of lthification which involves the compaction and cementation of sand grains.
The appearance of spiral galaxies vary in the following ways:
A. They vary in how tightly their arms are wound.
D. Some have a band of stars and materials through their middle, but others do not
Spiral galaxies are the galaxies where the gas clouds and the stars are concentrated in spiral arms.
Examples of spiral galaxies include<em> Milky way, Sunflower Galaxy, Andromeda Galaxy, </em>etc.
It should be noted that <em>spiral galaxies</em> vary in how tightly their arms are wound while some have a band of stars and materials through their middle, but others do not.

Answer:
They are <em>directly proportional</em> to gravitational force.
Explanation:
Newton's Law of Gravity states that 
. The two "m" values are the masses of the objects, <em>r</em> is the distance between their centers, and G is the gravitational constant. Notice how the "m" values are in the fraction's numerator (i.e., on top)? That means <em>increasing</em> even one of the objects' masses will <em>increase</em> the gravitational force. This is known as a <em>direct relationship</em>.
Of course, you could always use the wonderful table provided to solve this! You don't believe what I wrote above? Take on of the two objects' masses, divide the gravitational force by that number, and see what happens. Multiply the two masses together, and see what happens. Prove it for yourself!
I hope this increases your understanding of this concept. Have yourself a wondrous day, 'kay?
To operate a mixer circuit , Anne should use a (motor, buzzer, bulb, or battery) to transfer electric energy into motion. She should also use a (switch, resistor, buzzer, or bulb) to start and stop the flow of current.
An electric-powered circuit consists of a device that gives energy to the charged particles constituting the modern-day, consisting of a battery or a generator; devices that use cutting-edge, including lamps, electric cars, or computer systems; and the connecting wires or transmission traces.
An electrical circuit is an interconnection of electrical components or a version of such an interconnection, consisting of electrical elements. an electrical circuit is a network along with a closed loop, giving a go-back direction for the cutting-edge.
An electrical circuit consists of a source of electrical strength, two wires that can convey electric power present day, and a mild bulb. One stop of both the wires is hooked up to the terminal of a mobile at the same time as their free ends are related to the light bulb. the electric circuit is damaged while the bulb is switched off.

Answer:
<h3>143.815 N</h3>
Explanation:
when a person is pushing a carton in an inclined plane there is two forces acting against the applied force,
- component of gravity or mgsinθ
the carton goes up ( constant velocity ) only if sum of these two forces becomes equal to applied force
from the question,
weight of the carton,mg = 245 N
angle of incline,θ = 15°
coefficient of friction, μ = 0.340
∵ the applied force, F = mgsinθ + μmgcosθ
= mg ( sinθ + μcosθ)
= 245 ( sin 15° + 0.340 cos 15°)
= 245 ( 0.259 + 0. 328)
= 143.815 N
