which is the hottest planet in our solar system​

Explanation:

Potential energy is the energy occupied by an object or substance due to its position.

For example, a sled drops 20 meters in height on a hill shows that a decrease in height is taking place.

Hence, potential energy is involved there.

Kinetic energy is the energy acquired by an object due to its motion.

For example, a rider is going 20 m/s at the bottom of the hill shows that rider is in motion due to which it has kinetic energy.

Answer:

I)  the correct one is A

II)  the alternatives C

III) corresponds to option D

IV)  alternative B

Explanation:

Various information can be obtained from the speed versus time graphs

* If the graph is an inclined line, the speed is constant

* if the graph is a horizontal line the velocity is zero

In this case, the first graph (I) has two parts: an inclined line that corresponds to a uniform movement with speed and a second one, so that it is a horizontal line that indicates that the body is stopped.

If we see the different alternatives, the correct one is A

The second graph (II) has a movement with constant speed second period of being stopped

This graph corresponds to the alternatives C

The third graph (III) the body moves at constant speed without stopping

This corresponds to option D

The fourth graph (IV) the body moves with a slow speed and after 40 s it stops

This graph is associated with alternative B

Answer:

fertilization and it produces a Zygote

Explanation:

If the satellite is moving too quickly then the gravitational attraction between the Earth and the satellite is too weak to keep it in orbit. If this is the case, the satellite will move off into space. This occurs at speeds around or above 11,200 metres per second (m/s).

Answer:

A. 59.4

Explanation:

The refractive index of the glass, n₁ = 1.50

The angle of incidence of the light, θ₁ = 35°

The refractive index of air, n₂ = 1.0

Snell's law states that n₁·sin(θ₁) = n₂·sin(θ₂)

Where;

θ₂ = The angle of refraction of the light, which is the angle the light will have when it passes from the glass into the air

Therefore;

θ₂ = arcsin(n₁·sin(θ₁)/n₂)

Plugging in the values of n₁, n₂ and θ₁ gives;

θ₂ = arcsin(1.50 × sin(35°)/1.0) ≈ 59.357551° ≈ 59.4°

The angle the light will have when it passes from the glass into the air, θ₂ ≈ 59.4°.

[tex]h_{moon} = 11.8\ m[/tex]

Explanation:

Since the work done is same everywhere in the universe. Hence, the work done in jumping will be same for the person on moon and earth:

[tex]W_{moon} = W_{earth}\\\\P.E_{moon} = P.E_{earth}\\\\mg_{moon}h_{moon} = mg_{earth}h_{earth}\\\\g_{moon}h_{moon} = g_{earth}h_{earth}\\\\(1.66\ m/s^2)h_{moon} = (9.8\ m/s^2)(2\ m)\\\\h_{moon} = \frac{(9.8\ m/s^2)(2\ m)}{1.66\ m/s^2}\\\\h_{moon} = 11.8\ m[/tex]

The net displacement of the body is

∆x = (4, 3, 3) m - (-5, 3, 1) m = (9, 0, 2) m

so the work done by F = (3, 0, 4) N in the direction of ∆x is

F • ∆x = (3, 0, 4) • (9, 0, 2) N•m = (27 + 0 + 8) N•m = 35 J

The angle between the force and initial velocity v₀ is θ, such that

F • v₀ = ||F|| ||v₀|| cos(θ)

(3, 0, 4) • (6, 1, 1) N•m/s = √(3² + 0² + 4²) √(6² + 1² + 1²) cos(θ) N•m/s

==>   cos(θ) = (18 + 0 + 4) / (√25 × √38) = 22/(5√38)

==>   θ = arccos(22/(5√38)) ≈ 44.5°

Answer:

H = 1/2 * g * t^2     since initial velocity is zero

v = g * t    where v is the final velocity

t = v / g

H = 1/2 g * v^2 / g^2 = 1/2 v^2 / g

v = (2 * H * g)^1.2

v = (2 * 500 * 9.8)^1/2 = 99 m/s

Check: t = v / g = 99 / 9.8 = 10.1 sec

H = 1/2 * 9.8 * 10.1^2 = 500 m

Explanation:

I think a) Waste product and b) 80%

Explanation:

I think number has the greater pressure because the molecules are seen tightly packed

Answer:

I think part A) is b because there's more matter(molecules) inside the second so it has more tension

and to part b) I think it would deflated because the air molecules decrease when the temperature does I think.

oxygen is used up is the answer

Explanation:

These vaporized molecules are drawn up into the flame, where they react with oxygen from the air to create heat, light, water vapor (H2O) and carbon dioxide (CO2).

Answer: [tex]3.5\ km[/tex]

Explanation:

Given

Car starts from the state of rest and acquires a velocity of [tex]70\ km/hr[/tex] in 6 minutes

Final velocity in m/s is [tex]v=70\approx 19.44\ m/s[/tex]

Using equation of motion

[tex]v=u+at\\\Rightarrow 19.44=0+a(6\times 60)\\\Rightarrow a=0.054\ m/s^2[/tex]

Distance covered in 360 s

[tex]\Rightarrow v^2-u^2=2as\\\Rightarrow 19.44^2-0=2\times 0.054\times s\\\Rightarrow s=3500.64\ m\approx 3.5\ km[/tex]

Answer:

80 Ω.

Explanation:

In this circuit the resistances are in series.The equivalent resistance of a series circuit is equal to the sum of the resistances. Req= 60 + 20 = 80 Ω.

The equivalent resistance of the circuit is 80 Ω. Hence, option (D) is correct.

Resistance is characterized as a conductor's quality that opposes the flow of electric current. The ratio of the applied voltage to the electric current passing through it is another definition for it.

A series combination of resistors is one in which two or more are linked end to end consecutively. Any number of resistances connected in series will result in a total resistance equal to the sum of the individual resistances.

In this diagram, two resistors of resistance 60 Ω and 20 Ω are connected in series combination.

So,  the equivalent resistance of the circuit is =  60 Ω + 20 Ω  = 80 Ω.

Coordinates of y-intercept : (0,3)

Slope = 2

Another coordinate = 2 steps of rise and 1 step of run = (1,5)

Verification

Slope = (3-5) / (0-1) = -2 / -1 = 2

Answer:

Explanation:

In a velocity/time (aka acceleration) graph, the slope of a line indicates the value of the acceleration in m/s/s. Acceleration is the change in velocity over the change in time. From 0 - 2 seconds, there is no change in velocity, so the acceleration during this interval is 0 (which is the same as the slope of the line). From 2 - 4 seconds, the slope of the line is -2, so the acceleration during the time interval from 2 to 4 seconds is -2 (negative because David is slowing down but is still going the same direction: to the right).

Given:

distance of observer from the sound source, [tex]s=70~m[/tex]

distance between the source of image information sender and the receiver, [tex]d=45~miles=72420.48~m[/tex]

Assumptions:

speed of sound, [tex]v=343~m/s[/tex]

speed of the image information being sent, [tex]c=3\times 10^8~m/s[/tex] (we assume it to be nearly the speed of light in vacuum)

Solution:

Time taken by the sound to reach the observer:

[tex]time=\frac{distance}{speed}[/tex]

[tex]time=70\div 343[/tex]

[tex]time \approx 0.2~s[/tex]

Time taken by the image to reach the destination:

[tex]time=2.4\times 10^{-4}~s[/tex]

Answer:

Explanation:

The Law of Momentum Conservation applies and its equation is:

[tex][(m_1v_1)+(m_2v_2)]_b=[(m_1v_1)+(m_2v_2)]_a[/tex] and filling in and solving for v2:

[tex][(3.0*2.0)+(1.0*-2.0)]_b=[(3.0*0)+(1.0v_2)]_a[/tex] and

6.0 - 2.0 = 0 + 1.0v₂ and

4.0 = v₂ in the initial direction of the 3.0 kg ball (since the velocity of the 3.0 kg ball is positive and the velocity of the 1.0 kg ball is negative and our answer is positive).

3) Act on different objects

Explanation:

Newton's third law of motion states that for every action there is an equal and opposite reaction.

Action-reaction force pairs make it possible for fishes to swim, birds to fly, cars to move, etc.

Basically, action-reaction force pairs are characterized by the following statements;

I. The forces are the same type such as magnetic force, contact force or gravitational force.

II. The forces are equal in magnitude but opposite in direction.

III. They act up on two different bodies.

Hence, the two forces that make up 3rd law of motion can act on different objects.

For example, while driving down the road, a bug strikes the windshield of a vehicle (Action) and makes a quite obvious mess in front of the face of the driver of the vehicle (Reaction) i.e the bug hit the vehicle and the vehicle hits the bug.

Answer:

Explanation:

First off, let's call the -15 degree water solution1, and the 32 degree water solution2. The formula for this is

[tex]t_f=\frac{(m_1*spheat_1*temp_1)+(m_*spheat_2*temp_2)}{(m_1*spheat_1)+(m_2*spheat_2)}[/tex]

where spheat is specific heat of water that I found to be 4182 J/(kgC). This means that we need our masses in kg and they are currently in g.

100 g = .100 kg and

220 g = .220 kg. Now we're ready to plug everything in:

[tex]t_f=\frac{(.100*4182*-15)+(.220*4182*32)}{(.100*4182)+(.220*4182)}[/tex] and

[tex]t_f=\frac{-6273+29441.28}{418.2+920.04}[/tex] and

[tex]t_f=\frac{23168.28}{1338.24}[/tex] so

[tex]t_f=17.3[/tex] °C
