Answer:

[tex]F_c = \frac{KQ_1Q_2}{R^2}[/tex]

Explanation:

Coulomb’s law is given as;

[tex]F_c = \frac{KQ_1Q_2}{R^2}[/tex]

where;

F is the electric force between q₁ and q₂

k is the coulomb’s constant  = 9 x 10⁹ Nm²/C²

r is the distance between the two charges

q₁ and q₂ are the two charges

Therefore, the coulomb’s law is given as [tex]F_c = \frac{KQ_1Q_2}{R^2}[/tex]

Speed is equal to distance over time.

[tex]s=\frac{d}{t}[/tex]

The distance is 400 meters and the time is 50 seconds.

[tex]d= 400 \ m \\t= 50 \ s[/tex]

Substitute the values into the formula.

[tex]s=\frac { 400 \ m }{ 50 \ s}[/tex]

Divide.

[tex]s= 8 \ m/s[/tex]

Explanation:

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

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.

Saturn is a planet in solar system. It's ring is made out of small covered ice particle. It has over 30 moons.

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 .

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.

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.

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

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.

One reason that electromagnetic waves are used in long-distance communication is, that they do not lose energy over long distances. So Option C   is correct

Electromagnetic waves are a type of wave that consists of oscillating electric and magnetic fields. They are propagated through space or through a material medium, and they have the ability to travel through a vacuum, which is the absence of matter. Electromagnetic waves have a wide range of frequencies, which determines the type of electromagnetic wave. The most familiar types of electromagnetic waves include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

One of the property of the electromagnetic waves is that they do not lose energy over long distances.
