A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared. For example, standard atmospheric pressure (or 1 atm) is defined as 101.325 kPa. The millibar, a unit of air pressure often used in meteorology, is equal to 100 Pa.

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 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.
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.

Mosa believes that ocean currents help to regulate the climate of the earth. Explain why.
Answer:
Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth's land would be habitable.
Ocean currents help to regulate the climate of the earth as it transports warm water from the equator to the polar region and carry cold water from poles back towards the equator .
What is an ocean currents ?
An ocean current is a continuous , directed movement of sea water generated because wind , breaking waves , temperature , salinity differences etc .
Ocean currents that move from north to south ,transports warm water from the equator to the polar region and carry cold water from poles back towards the equator . This is how ocean currents help to counteract the uneven distribution of solar radiation , without ocean current it would be really hot in equator and really cold at poles.

Why do you think the speed of sound is higher
in solids, than liquids and gases?
Answer:
Explanation:
Particles of a solid are closely packed, and when a solid is hit to produce a sound the kinetic energy present in the solid will cause the particles to vibrate vigorously in the intermolecular spaces in the solid, whereas the paticles of liquids and gases are rather further apart therefore having large intermolecular spaces between particles.

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.

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

Explain what makes up a circuit .
Explanation:
An electrical circuit needs:
a source of electrical power (this could be a power plant or a battery)
a material along which the electricity can flow (this may be a copper wire)
something to power (this could be a bulb)
The circuit is connected in a loop. Then, the source of power pushes electrons around the wire. It lights the bulb and continues in the circuit until it is broken.
A simple circuit lights one bulb. More difficult circuits might have several switches and loops. This would allow different groups of lights to be turned on or off at the same time.
