All of the following processes are the ones that lead directly to the formation of sedimentary rock EXCEPT-
deposition of rock fragments.
O
freezing of water in cracks in rock.
o
melting of rock deep underground.
movement of wind that carries earth material.
Answer:
melting of rock deep underground.
Explanation:
The melting of rocks deep underground does not produce sedimentary rocks. Most igneous rocks are produced by this process.
When molten rocks underground called magma is solidified in the subsurface, it results into the formation of igneous bodies.
Sedimentary rocks forms by the accumulation of sediments. Inside the basin where the sediments are deposited, they are compacted, cemented and lithified. Chemical and physical weathering of rocks produces sediments.is cereal a soup? explain why or why not

What is Electrical energy?When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible.
When two charge are in opposition to one another, they repel one another. The term "neutral" refers to an object has no net charge. The early understanding of the way charged particles interact is now referred to as classical electrodynamics, and it is still true for issues that do not demand for taking into account quant phenomena.
Electrical charge is a preserved attribute, meaning that the net charged of an isolated system—that is, the sum of the positive and negative charges—cannot change. Particles at the subatomic level carry an electric charge.
The second diagram from the option will have no current in it because the wires are not connected with the battery, so the flow of current will not take place.

incline plane is given length 12m,load 600 newton,effort 200 Newton, Height 3 metre find its velocity ratio and mechanical advantage
Answer:
i. The velocity ratio of the plane is 4.
ii. The mechanical advantage of the plane is 3.
Explanation:
i. The velocity ratio (VR) of an inclined plane is ratio of its length to the height. It is given as;
VR = [tex]\frac{length of the plane}{height}[/tex] = [tex]\frac{l}{h}[/tex]
Given: l = 12 m, L = 600 N, E = 200 N, h = 3 m.
So that,
VR = [tex]\frac{12}{3}[/tex]
= 4
The velocity ratio of the plane is 4.
ii. Mechanical advantage (MA) expresses the relationship between the load overcome to effort applied.
MA = [tex]\frac{Load}{Effort}[/tex] = [tex]\frac{L}{E}[/tex]
= [tex]\frac{600}{200}[/tex]
= 3
The mechanical advantage of the plane is 3.
Therefore, the velocity ratio of the inclined plane is 4, and its mechanical advantage is 3.

A laser beam is directed at the Moon, 380,000 km from the Earth. The beam diverges at an angle of \thetaθ of 0.8 x 10-5 rad. What diameter spot, in m, will it make on the Moon?
Answer:
3040 m
Explanation:
The formula to apply here is ;
d=∅*r where
d is the diameter of the spot , ?
∅ is angle of divergence in radians, = 0.8 * 10⁻⁵rad
r is distance of Moon from Earth, =380,000 km
Applying the formula as;
d=∅*r
d= {0.8 *10⁻⁵} * 380,000 * 1000
d= 3040 m

A boy is pulling a 150 kg crate with a force of 1150 N. If the crate experiences a frictional force of 490 N, find:
a) The acceleration of the crate.
b) The normal force acting on the crate.
First, let's find the resultant, and applicate 2nd law of Newton using the resultant, so:
R = ma
F - Ff = ma
Data:
F = Force = 1150 N
Ff = Friction force = 490 N
m = Mass = 150 kg
a = Aceleraction = ?
Replacing according our data:
1150 N - 490 N = 150 kg * a
660 N = 150 kg * a
660 N / 150 kg = a
a = 4,4 m/s² ← Aceleration of the object
For the normal force:The normal force IS NOT the resultant force, the normal force's the force between the ground and the object, in another words, is the weight of the object, and for the weight:
w = mg
w = 150 kg * 10 m/s²
w = 1500 N ← Normal force between object and ground.

A tennis ball launcher works by using a spring to
propel the ball forward.
One model of tennis ball launcher has
advertised that it is capable of imparting
15,000 J of kinetic energy to a 0.5 kg ball
initially at rest. A student carefully measures the
compression of the spring to be 0.10 m.
What is the value of the spring constant for the
tennis ball launcher according to the data
provided?
Answer:
3MN/m
Explanation:
Step one:
given data
Kinetic Energy KE=15,000J
mass m= 0.5kg
compression x= 0.1m
Step two:
The expression for the energy stored in spring is
[tex]KE= 1/2ke^2\\\\15000=1/2 *k*0.1^2\\\\15000=1/2*k*0.01\\\\15000=0.005k\\\\[/tex]
divide both sides by
0.005
[tex]k= 15000/0.005\\\\k=3000000\\\\k= 3MN/m[/tex]
From conservation of energy, the value of the spring constant for the tennis ball launcher according to the data is 3 x [tex]10^{6}[/tex] Nm
The work done by a tennis ball launcher by using a spring to propel the ball forward is equal to the kinetic energy which is 15,000 Joule. That is,
W = K.E
The given parameters are:
K.E = 15,000 J
Mass m = 0.5 kg
compression x = 0.1 m
The elastic potential energy on the spring will be equal to the work done by the tennis ball launcher. That is,
E = W
since W = K.E
E = K.E
1/2k[tex]x^{2}[/tex] = 1/2m[tex]v^{2}[/tex] = 15,000
1/2k[tex]x^{2}[/tex] = 15000
Substitute for 0.1 for x
1/2 K ([tex]0.1^{2}[/tex]) = 15000
[tex]0.1^{2}[/tex] K = 30000
K = 30000/0.01
K = 3 x [tex]10^{6}[/tex] Nm
Therefore, the value of the spring constant for the tennis ball launcher according to the data is 3 x [tex]10^{6}[/tex] Nm

2 equal charges are kept at x=a and x=-a. there can be only 1 point where the electric field will be 0? how, can anyone explain?
Answer:
At the midpoint of the line joining the two equal charges
Explanation:
The midpoint of the line joining the two equal charges has equal distance from each charge. Since the charges are at x = a and x = -a, at the midpoint of the line joining the two equal charges, the magnitude of the electric field experienced as a result of each charge is the same. But these two fields are in opposite direction, hence the net resulting electric field would be equal to zero.

An 82 kg man, at rest, drops from a diving board 3.0 m above the surface of the water and comes to rest 0.55 s after reaching the water. What force does the water exert on him?
Answer:
1626.4 N
Explanation:
Given that a 82 kg man, at rest, drops from a diving board 3.0 m above the surface of the water and comes to rest 0.55 s after reaching the water. What force does the water exert on him?
The parameters to be considered are:
Distance S = 3m
Time t = 0.55s
Since the man started from rest, initial velocity u = 0
Using second equation of motion
S = Ut + 1/2at^2
3 = 1/2 × a × 0.55^2
3 = 1/2 × a × 0.3025
a = 3/ 0.15125
a = 19.83 m/s^2
Force = mass × acceleration
Force = 82 × 19.83
Force = 1626.4 N
Therefore, the force that water exerted on him is 1626.4 N
A 3.0 g bullet traveling at a speed of 400 m/s enters a tree and exits the other side with a speed of 200 m/s. Where did the bullet's lost KE go, and what was the energy transferred?
Answer:
1800J
Explanation:
Step one:
given data
mass of bullet m= 3g= 0.03kg
initial velocity u = 400m/s
final velocity v= 200 m/s
Step two:
1.The bullet's lost kinetic energy went inside the tree.
2. The energy transferred is computed as
= initial KE- KE final
Initial KE= 1/2mu^2
Initial KE= 1/2*0.03*400^2
Initial KE= 1/2*0.03*160000
Initial KE= 1/2*4800
Initial KE= 2400J
KE final= 1/2mv^2
KE final= 1/2*0.03*200^2
KE final= 1/2*0.03*40000
KE final= 1/2*1200
KE final= 600J
KE transferred = 2400-600
KE transferred= 1800J

B. 9,800 m/s
C. 450 m/s
D. 13 m/s
Answer:
C. 450
it should be right
The new speed of sound wave is 450 m/s. Hence, option (C) is correct.
What is sound wave?A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid matter).
Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves.
Frequency of sound wave is = 16 Hz.
Wavelength of the sound wave is = 28 m.
Hence, new speed of sound wave is = 16 × 28 meter/second
= 448 meter/second
