Answer:

The amount of each gas that can dissolve in the ocean depends on the solubility and saturation of the gas in water. Solubility refers to the amount of a dissolved gas that the water can hold under a particular set of conditions, which are usually defined as 0o C and 1 atmosphere of pressure.

Answer: the motion of the air above the ocean water

Explanation:

Answer:

See Explanation

Explanation:

Given

Cyclist 1:

[tex]Distance = 40km[/tex]

[tex]Time = 2hr[/tex]

[tex]Direction = East[/tex]

Cyclist 2:

[tex]Distance = 10km[/tex]

[tex]Time = 0.5hr[/tex]

[tex]Direction = West[/tex]

The question requires options. Since none is given,  I'll answer on a general term.

First, calculate the speed of both cyclists

[tex]Speed = \frac{Distance}{Time}[/tex]

Cyclist 1:

[tex]Distance = 40km[/tex]

[tex]Time = 2hr[/tex]

[tex]Speed = \frac{40km}{2hr}[/tex]

[tex]Speed = 20km/hr[/tex]

Cyclist 2:

[tex]Distance = 10km[/tex]

[tex]Time = 0.5hr[/tex]

[tex]Speed = \frac{10km}{0.5hr}[/tex]

[tex]Speed = 20km/hr[/tex]

The following can be deduced from above:

Oxygen is more chemically reactive than nitrogen because Oxygen needs to gain only 2 electrons to have a full octet, while nitrogen needs to gain 3. The correct option is A.

The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.

Valence electrons are the electrons present in the outermost shell of an atom. They can easily be determined by the number of valence electrons in an atom by looking at the specific group in the periodic table.

The fewer number of electrons in the valance shell, the more reactive is the element.

Oxygen needs to gain only 2 electrons to have a full octet, while nitrogen needs to gain 3.

Thus, Oxygen is more chemically reactive than nitrogen.

Then the correct option is A.

Explanation:

Apex built different

Answer:

I found it would be quadrupled if it was doubled

Explanation:

The kinetic energy of an object is the energy possessed by the object due to its motion. It is given by:

where

m is the mass of the object

v is its speed

From the equation, we notice that the kinetic energy is:

Directly proportional to the mass

Proportional to the square of the speed

In this problem, the initial kinetic energy of the object is

K = 100 J

Later, the speed of the object is doubled:

v' = 2v

Therefore, the new kinetic energy will be

So, we see that the kinetic energy will quadruple.

•Most of the components that make up curcuits are conductors. Electricity flows easily thought conductors such as metal or water.Electricity does not flow easily thought insulators such as wood or rubber.

•When a battery is used to power a circuit, the circuit the current must travel from one pole of the battery to the opposite battery.

•Resisotors show the flow of Electricity throught a circuit this can prevent components of the circuit from 'brning out'. In a curcuit diagram, resistors are represented by bending lines.

Answer:

the time of motion of the ball is 6.89 ms.

Explanation:

Given;

angular speed, ω = 38 rad/s

angular distance, θ = 15 degrees

Angular distance in radian;

[tex]\theta = 15^0 \times\frac{2\pi \ rad}{360^0} = 0.2618 \ rad[/tex]

Time of motion is calculated as;

[tex]time = \frac{angular \ distance}{angular \ speed} \\\\t= \frac{\theta}{\omega} = \frac{0.2618 \ rad}{38 \ rad/s} \\\\t = 6.89 \ \times 10^{-3} \ s\\\\t = 6.89 \ ms[/tex]

Therefore, the time of motion of the ball is 6.89 ms.

2800 m

Given

time = 80 s

average velocity = 35 m/s

Required

total distance before it broke down

Solution

Average velocity : total displacement : total time

Can be formulated

avg velocity = Δx : Δt

Input the value :

Δx=avg velocity x Δt

Δx = 35 m/s x 80 s

Δx = 2800 m

In addition, if we are asking for velocity, we must know the starting and ending points (displacement)

But if we calculate the total distance, what is written is the average speed

avg speed = total distance : total time

Answer:

The diameter of the gold nucleus is 3.0 × 10⁻⁵ nm

Explanation:

The given parameter of the gold atom are;

The diameter of the gold atom = 1/6,000 × The diameter of the atom

The diameter of a gold atom = 0.18 nm

The diameter of the gold nucleus, [tex]d_{Gold -nucleus}[/tex] = 1/6,000 × 0.18 nm = 0.00003 nm

∴ The diameter of the gold nucleus, [tex]d_{Gold -nucleus}[/tex] = 0.00003 nm = 3.0 × 10⁻⁵ nm.

Explanation:

The force acting on the shark, [tex]F=2.5\times 10^4\ N[/tex]

Acceleration of the shark, a = 1.25 m/s²

We need to find the mass of the Shark. The force acting on an object is given by :

F = ma

m is the shark's mass

So,

[tex]m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20000\ kg[/tex]

So, the mass of the Shark is 20000 kg.

Answer:

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. ... For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes.

Explanation:

Answer:

I will assume that “maximum force” implies the constant application of power  P  = 400 hp (international) to accelerating the vehicle. The force will therefore vary with speed as the vehicle accelerates. I will also assume that all engine energy goes into accelerating the vehicle, rather than rotating elements like its wheels.

In this case the 400 hp (equivalent to 298,280 watts) is applied for time  t  = 2 seconds. Therefore the kinetic energy of the vehicle is increased by:

ΔKE=Pt=(298,280)(2)=596,560  joules.

The initial kinetic energy is:

KEinitial=12mv2

=(0.5)(1600)(82)=51,200  joules.

Therefore final kinetic energy is:

KEfinal=KEinitial+ΔKE

=51,200+596,560

=647,760  joules

Therefore final vehicle velocity can be found:

KEfinal=12mv2

v=2KEfinalm−−−−−−−−√

=(2)(647,760)1600−−−−−−−−−−−√

= 28.455 m/s
