Answer:
The two moons of Mars are Phobos and Deimos. They are irregular in shape. Both were discovered by American astronomer Asaph Hall in August 1877 and are named after the Greek mythological twin characters Phobos (fear) and Deimos (panic) who accompanied their father Ares into battle, SO they were irregular in shape
Explanation:
what would happen if a paper clip that is not a permanent magnet was brought close to the south pole of a permanent magnet?
Answer:
Because this pole is different from the original pole that magnetized the paperclips, the top paperclip will become demagnetized in the opposite direction and the bottom paperclip will be repelled away

PLEASE HELP ME,, I WOULD BE SO HAPPY
You push against a wall with all your might and generate an insane 2500N of force. However, the wall doesn't move. How much work did you do?PLEASE HELP ME,, I WOULD BE SO HAPPY You push against a wall with all your might and generate an insane 2500N of force. However, the wall doesn't move. How much work did you do?
Answer: None
Explanation:
Since the wall did not move, it does not matter how much force you generated. You did no work in the physics sense.
Work is calculated by multiplying the displacement by the force. Since there was no displacement (no movement) we put the value as 0. 0 times anything is still 0, as shown below.
2500 N * 0 = 0.
You did no work, or 0 J of work.

Answer:
1Burning of fossil fuel
2Deforestation
3Waste disposal in landfills
Explanation: took test:)
Human activities intensify the greenhouse effect as:
Deforestation -destroys natural carbon sinks, leading to more CO₂ in the air
Burning fossil fuels - the primary cause of human-created carbon emissions
Waste disposal in landfills - emits methane from decomposing matter
What is the greenhouse effect?The greenhouse effect can be defined as a process that occurs when energy heats the planet's surface, but greenhouse gases in the atmosphere stop the heat from returning directly to space and warm the earth.
The natural greenhouse effect retains the earth from freezing at the below-freezing temperature that it will freeze if there were no greenhouse gases. Human activities increase greenhouse gases and trap larger amounts of heat, which cause the Earth's temperature to grow warmer over time.
The Sun delivers most of its energy as visible light and near-infrared light, while the average surface temperature of the Earth emits longer-wavelength infrared IR and radiant heat. These gases emit radiant heat in all directions, traveling heat to the air and warming other greenhouse gases in the atmosphere.

An 1876 N crate is being pushed across a level force at a constant speed by a force of 747 N. What is the coefficient of kinetic friction?
0.16
0.40
0.08
not enough information
The crate only moves horizontally, so its net vertical force is 0. The only forces acting in the vertical direction are the crate's weight (pointing downward) and the normal force of the surface on the crate (pointing upward). By Newton's second law, we have
∑ F (vertical) = n - mg = 0 → n = mg = 1876 N
where n is the magnitude of the normal force.
In the horizontal direction, the crate is moving at a constant speed and thus with no acceleration, so it's completely in equilibrium and the net horizontal force is also 0. The only forces acting on it in this direction are the 747 N push (pointing in the direction of the crate's motion) and the kinetic friction opposing it (pointing in the opposite direction). By Newton's second law,
∑ F (horizontal) = 747 N - f = 0 → f = 747 N
The frictional force is proportional to the normal force by a factor of the coefficient of kinetic friction, µ, such that
f = µn → µ = f / n = (747 N) / (1876 N) ≈ 0.398188 ≈ 0.40

What is the current in a 160 V circuit if the resistance is 2 ohms?
Answer:
Question: What is the current in a 160V circuit if the resistance is 2Ω?
Answer:
Voltage ( V ) = 160V
Resistance ( R ) = 2Ω
Current ( I ) = ?
By Ohms law
⇒ V = IR
⇒ 160 = I × 2
⇒ I = 160 / 2 = 80A
\rule{200}2
Question: What is the current in a 160V circuit if the resistance is 20Ω?
Answer:
Voltage ( V ) = 160V
Resistance ( R ) = 20Ω
Current ( I ) = ?
By Ohms law
⇒ V = IR
⇒ 160 = I × 20
⇒ I = 160 / 20 = 8A
\rule{200}2
Question: What is the current in a 160V circuit if the resistance is 10Ω?
Answer:
Voltage ( V ) = 160V
Resistance ( R ) = 10Ω
Current ( I ) = ?
By Ohms law
⇒ V = IR
⇒ 160 = I × 10
⇒ I = 160 / 10 = 16A
\rule{200}2
Question: Based on questions 2, 3, and 4, what happens to the current in a circuit as the resistance decreases? Increases?
Answer:
From ohms law
⇒ I = V / R
If we take Voltage as proportionality constant
⇒ I ∝ 1 / R
So, we can conclude that current is inversely proportional to resistance.
From 2, 3, 4 questions we can conclude that,
If resistance increases, current decreases and when resistance decreases, current increases.

O It will increase in frequency.
O It will decrease in speed.
O It will increase in speed,
O It will decrease in wavelength.
The most likely outcome when a sound wave moves from the air through a solid is : ( C ) It will increase in speed
Sound wavesA sound wave is disturbance pattern that goes through a medium such as air and any liquid or solid medium. when a sound wave moves from air medium through a solid medium the speed at which the sound waves moves will increase due to the change in medium.
Hence we can conclude that the most likely outcome when a sound wave moves from the air through a solid is it will increase in speed.

An 80 kg diver jumps from a 10 m high platform. What is the gravitational potential energy of the diver right before they jump (top of platform)
Answer:
0 Joules.
Explanation:
Given the following data;
Mass = 80kg
Height = 10m
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
[tex] G.P.E = mgh[/tex]
Where;
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
We know that acceleration due to gravity is equal to 9.8m/s²
But since we're determining the gravitational potential energy just before the driver jump, the height would be zero (0) meters.
Gravitational potential energy= mgh
Gravitational potential energy = 80*9.8*0
Gravitational potential energy = 0 Joules.
This ultimately implies that, if an object or body hasn't moved (jumped) from its reference point, its gravitational potential energy would be equal to zero.
Which of the following is not a change that occurred to organisms over time in the fossil record?
A. Decrease in in the number of species
B. Greater complexity
C. Increase in size
D. More diversity
Answer:A
Explanation: my teacher told me lol
The option that is not a change that occurred to organisms over time in the fossil record is A. Decrease in the number of species
A fossil record simply refers to the history of the life of the fossils. It means the remains of imprints of the organisms that are from earlier geological periods.
It should be noted that the fossil record is important to archeologists as it helps in placing events in their appropriate eras.
A change that didn't occur to the organisms over time in the fossil record is the decrease in the number of species.

4.00 kg glass coffee cup is 30.0°C at room temperature. It is then plunged into hot dishwater at a temperature of 90.0°C, as shown in Figure below. If the temperature of the cup reaches that of the dishwater, how much heat does the cup absorb? C glass = 837 (J/kg.C)*
Answer:
Q = 200800 Joules.
Explanation:
Given the following data;
Mass = 4kg
Initial temperature = 30.0°C
Final temperature = 90.0°C
Specific heat capacity of glass = 837 J/kg°C
To find the quantity of heat absorbed;
Heat capacity is given by the formula;
[tex] Q = mcdt[/tex]
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt = T2 - T1
dt = 90 - 30
dt = 60°C
Substituting the values into the equation, we have;
[tex] Q = 4*837*60[/tex]
Q = 200800 Joules.
Therefore, the amount of heat absorbed is 200800 Joules.
