Why the surface of Mars is red?
Answer:
Because the iron oxide chemicals in its soil looks like rust.
Answer:
Hey mate.....
Explanation:
This is ur answer.....
Mars is known as the Red Planet because the iron oxide chemicals in its soil looks like rust. The simple explanation for the Red Planet's color is that its regolith, or surface material, contains lots of iron oxide — the same compound that gives blood and rust their hue.

When sediment created by weathering and moved by erosion settles in a different location due to gravity
A. Deposition
B. Weathering
C. Erosion
D.Abiotic
Answer:
Deposition
Explanation:
The deposition phenomenon happens when sediment created by weathering and moved by erosion settles in a different location due to gravity
What is Erosion and Deposition?Deposition occurs when sediment, a combination of soil and rock produced by weathering, is eroded and transported to a new area.
Deposition is the act of depositing silt that has been transported by the wind, water, sea, or ice.
Earthen materials are worn away during erosion, a geological process in which they are moved by wind or water.
The removal of soil, rock, or dissolved material from one area on the Earth's crust and subsequent transport to another region for deposition are known as erosional processes. Erosion differs from weathering, which is a static process.
Given data ,
Let the sediment be deposited in an another location due to gravity
Now , As sediment, a mixture of soil and rock created by weathering, is eroded and moved to a new region, deposition takes place.
During three interrelated processes, lithification converts loose sediment grains that are produced by weathering and transported by erosion into clastic sedimentary rock. Deposition occurs when gravity and friction work against the forces that move sediment, enabling it to build up.
Hence , when sediment created by weathering and moved by erosion settles in a different location due to gravity , deposition takes place

Some ancient objects have been well-preserved in high mountain ranges,
where the concentration of oxygen is low. Otzi the Iceman lived more than
5,000 years ago. Archaeologists found him with his leather pouch, clothes,
and tools perfectly preserved in the ice of the Alps.
Marie's mother lost a leather purse in the yard of their house in Florida, where
the air has more oxygen. Marie found it 30 years later under a tree. It was
rotted and decayed.
Review the information in the data table. What does this information tell you
about the rate of decay reactions relative to the concentration of oxygen?
Answer:
yeah
Explanation:
The information tells you about the rate of decay is that in Florida the reaction occurs more slowly when there is less oxygen in the air.
What is the rate of decay?The reduction in the number of radionuclides per unit time is the rate of decay.
The following table shows that the rate of decay only depends upon the level of oxygen. In Florida concentration of the oxygen in the air is high
Due to this the decay time is less.
The decay time is inversly propotional to the rate of decay. In Florida the rate of decay is high.
Hence the information is that reaction occurs more slowly when there is less oxygen in the air.

A force of 20 N acts upon a 5000g block. Calculate the acceleration of the object
Answer:
a = 4 m/s²
Explanation:
Given: 5000 g, 20N
To find: Acceleration (a)
Solution: Firstly, convert 5000g to kilograms
1000g = 1kg
∴ 5000g = 5kg if divided by 1000
A = F ÷ m
= 20 ÷ 5
= 4 m/s²
Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

Answer:
The height of the water column = 1.62405[tex]\overline{30}[/tex] × 10⁻¹ m
Explanation:
The air cavity in the Coke bottle = 0.220 m deep
The fundamental (frequency) it plays when water is added to shorten the column and it is blown across the top, f = 528 Hz
The given speed of sound in air, v = 343 m/s
We note that the air cavity in the coke bottle is equivalent to a tube closed at one end
The fundamental frequency for a tube closed at one end, 'f', is given as follows;
f = v/(4·L) = v/λ
Where;
L = The height of the water column
λ = The wavelength of the wave
∴ 4·L = v/f = (343 m/s)/(528 Hz) = 0.6496[tex]\overline{21}[/tex] m
∴ L = 0.6496[tex]\overline{21}[/tex] m/4 = 0.162405[tex]\overline{30}[/tex] m
The height of the water column = 1.62405[tex]\overline{30}[/tex] × 10⁻¹ m.

PLEASE HELP (NO LINKS!)As the pendulum swings from position A to position B, what is the
relationship of kinetic energy to potential energy (neglect friction)? (5
points)
The kinetic energy increase is equal to the potential energy decrease.
The potential energy increase is equal to the kinetic energy decrease.
The kinetic energy and potential energy remain the same.
The kinetic energy increase is more than the potential energy decrease.
Answer:
the kinetic energy decrease is equal to potential energy increase
If the potential energy of pendulum increases then the kinetic energy decreases and if the kinetic energy increases then the potential energy decreases.
what is conservation of energy?According to the work power theorem the total energy of any object will remain constant like the sum of the kinetic and the potential energy of the object will remain constant.
The potential energy of any object is due to its position with respect to the ground. If the object is at a height of H then it will have a potential energy because some energy is given to that object against the gravity to move it to the height H.
The kinetic energy is the energy due to the velocity of the object and is given as the product of half mass to the velocity square.
Now we will express it in the form of the formula for better understanding .
[tex]\rm Total\ energy= KE+PE[/tex]
Now in the pendulum the motion is back and forth with respect to its mean position. So the total energy in the pendulum is the sum of the kinetic energy and the potential energy.
Now if the pendulum attains the maximum displacement from its mean position then it will have maximum potential energy and zero kinetic energy at this point.
Now if the pendulum is at the mean position now it will have maximum kinetic energy and zero potential energy at this point.At this point the potential energy totally converted to the kinetic energy.
Now at the maximum displacement the kinetic energy totally converts into the potential energy of the pendulum.
Thus If the potential energy of pendulum increases then the kinetic energy decreases and if the kinetic energy increases then the potential energy decreases.

A horizontal spring is lying on a frictionless surface. One end of the spring is attaches to a wall while the other end is connected to a movable object. The spring and object are compressed by 0.065 m, released from rest, and subsequently oscillate back and forth with an angular frequency of 14.7 rad/s. What is the speed of the object at the instant when the spring is stretched by 0.032 m relative to its unstrained length
Answer:
0.832 m/s
Explanation:
The work done by the spring W equals the kinetic energy of the object K
The work done by the spring W = 1/2k(x₀² - x₁²) where k = spring constant, x₀ = initial compression = 0.065 m and x₁ = final compression = 0.032 m
The kinetic energy of the object, K = 1/2mv² where m = mass of object and v = speed of object
Since W = K,
1/2k(x₀² - x₁²) = 1/2mv²
k(x₀² - x₁²) = mv²
mv² = k(x₀² - x₁²)
v² = [(k/m)(x₀² - x₁²)]
taking square root of both sides, we have
v = √[(k/m)(x₀² - x₁²)] since ω = angular frequency = √(k/m),
v = √[(k/m)√(x₀² - x₁²)]
v = ω√(x₀² - x₁²)]
Since ω = 14.7 rad/s, we substitute the other variables into the equation, so we have
v = 14.7 rad/s × √((0.065 m)² - (0.032 m)²)]
v = 14.7 rad/s × √(0.004225 m² - 0.001024 m²)]
v = 14.7 rad/s × √(0.003201 m²)
v = 14.7 rad/s × 0.056577
v = 0.832 m/s
A baseball travels at a velocity of 45.3 m/s towards second base for 17 s. Calculate the displacement of the ball.
Answer:
770.1 m
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 45.3 m/s
Time (t) = 17 s
Displacement (d) =?
Velocity is defined according to the following formula:
Velocity = Displacement /Time
With the above formula, we can obtain the displacement of the ball as follow:
Velocity = Displacement /Time
45.3 = Displacement / 17
Cross multiply
Displacement = 45.3 × 17
Displacement = 770.1 m
Therefore the displacement of the ball is 770.1 m
Answer: 770.1 gravity multiplied by time
