How far has a dolphin traveled in kilometers if it swims for 1.8 h at 5.6 km/h ?

Answer:

I'm pretty Sure. Yea look.

Explanation:

Up to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.

Your question says 'in our solar system.' It might or might not be possible. It actually depends on whether the temperature of the planet, the atmosphere, availability of water & food & the things found there suit the needs of the organisms. As of now, no planet in our solar system or in the universe support the inhabitants of earth-like beings. But who knows? It's not entirely impossible either. Scientists say there were remains of water found in Mars which might prove the existence of extraterrestrials. Still, it has not been proved.

Through food chains, the carbon that is in plants moves to the animals that eat them. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

The power exerted by the small motor is ~

[tex] \large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}[/tex]

As we know, power is the rate at at which we perform a work, that is ~

Let's find the power exerted by motor if 520 J of work is done for 10 seconds ~

If a small motor does 520 J of work for 10 seconds, the power exerted by it is 52 Watts.

The quantity of energy moved or converted per unit of time is known as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units.

Power is also referred to as activity in ancient writings. A scalar quantity is power.

Given that the small motor does work  = 520 J

Time taken for the work =  10 seconds.

Hence, power of the small motor be = work done/time taken.

=520 j/10 second

= 52 Watt.

Explanation:

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

Answer:

The factors that affect the force of gravity are :

i) Mass

ii) Acceleration

In situation 4 will an object always stay motionless. When the applied forces add up to zero.

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.

The moment in the body is only due to the applied force. An object in scenario 4 remains stationary at all times. When all of the applied forces total up to zero.

Hence option 4 is correct.

Answer:

Technically everything has somewhat of a magnetic field. I guess

Answer: .

Explanation:

Newton's second law allows finding the result for the type of graph to find the gravity acceleration  is:

                     g = [tex]\frac{slope}{\sqrt{L} }[/tex]

Oscillatory motion is a simple harmonic motion where the restoring force is proportional to the displacement.

Newton's second law gives a relationship between the net force, the mass and the acceleration of a body, in the attached we can see a free body diagram of the system, let's apply Newton's second law.

                 [tex]t_y - W =0 \\T_x = m a[/tex]

Since the movement is circular, the acceleration is centripetal.

                [tex]a = \frac{v^2}{r}[/tex]

Let's substitute.

               [tex]t_x = m \frac{v^2}{r}[/tex]  

Let's use trigonometry to find the radius of the circle and the stress component.

              sin θ = [tex]\frac{r}{L}[/tex]  

              r = L sin  θ

             sin θ =  [tex]\frac{T_x}{T}[/tex]  

             cos θ = [tex]\frac{T_y}{T}[/tex]  

             Tₓ = T sin θ

             [tex]T_y[/tex] = T cos θ

Let's substitute.

            T sin θ = [tex]\frac{m v^2 }{L sin \theta }[/tex]  

            T sin² θ = [tex]\frac{m}{L} \ v^2[/tex]  

From the other equation.

             [tex]T_y= W \\T cos \theta = m g[/tex]  

Let's write our system of equations.

            T sin² θ  = [tex]\frac{m}{L} \ v^2[/tex]  

            T cos θ = m g

We solve the system by squaring the second equation and dividing.

             tan² θ = [tex]\frac{1}{g^2 L } \ v^2[/tex]  

             L g² tan² θ = v²

             v = g [tex]\sqrt{L}[/tex]  tan θ

Consequently, if the student makes a graph of the velocity versus the tangent of the angle, he obtains a straight line and the slope is:

             slope = g [tex]\sqrt{L}[/tex]

From this expression you can calculate the acceleration of gravity.

              [tex]g= \frac{slope}{\sqrt{L} }[/tex]  

In conclusion using Newton's second law we can find the result for the type of graph to find the gravity acceleration  is:

                 [tex]g = \frac{slope}{\sqrt{L} }[/tex]

Answer:

Horizontal Work done + vertical work done

Explanation:

1.) First calculate the work done to move box in horizontal direction:

W = Fs

= 25N × 120m

= 3000 Joules

2.) Work done against gravity in vertical direction:

Ep = mgh

= 90x10x.0.5

= 450 Joules

Total Work done = 3000 + 450 = 3450 Joules

Answer:Gold is metallic, with a yellow color when in a mass, but when excellently separated it may be black, ruby, or purple. Your density numbers have no units, so they are unusable.

If the numbers you give match to the densities of the given metal in g/ml or kg/L, it should be gold.

Density = mass/volume, so:

96.5g/5ml = 19.3 g/ml. So the answer is 19.3 gold.
