What would happen if the earth's core was destroyed?

Physics

Our atmosphere would be quickly stripped away, much like what apparently happened on Mars after its molten core cooled and solidified. The spinning Earth core is what helps create our magnetic field, without which means no Van Allen Belts, which mean solar radiation becomes more lethal than just sun burn

Distance between the two place is 35 kilometers . If two persons start running towards each other from these two place with a sp
pashok25 [27]

The first person = A

The second one = B

velocity of A = 3 km / h

velocity of B = 4 km / h

Distance of A = 3t

Distance of B = 35 - 4t

At what time do they meet?

3t = 35 - 4t

7t = 35

t = 5 hours

7 a.m. + 5 hours = 12 p.m.

Describe the difference between global knowledge and personal ideas.
iren2701 [21]

Answer:

Global knowledge is information that is widely accepted and been proven as the truth. It is information that may not necessarily have a source because it is common knowledge and not easily attributed to a certain source. Personal ideas are original to the author and may not be widely accepted. It is important to give credit to others by citing their work to acknowledge that this is not your own findings but rather someone else's. It is plagiarism to use someone else's work as your own without giving credit to their work. -W0lf93

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arr
Natalija [7]

Answer:

a) F = 680 N, b)  W = 215 .4 J , c)  F = 1278.4 N

Explanation:

a) Hooke's law is

              F = k x

To find the displacement (x) let's use the elastic energy equation

            K_{e} = ½ k x²

             k = 2 K_{e}  / x²

             k = 2 85.0 / 0.250²

             k = 2720 N / m

We replace and look for elastic force

            F = 2720  0.250

            F = 680 N

b) The definition of work is

          W = ΔEm

          W = K_{ef} - K_{eo}

          W = ½ k ( x_{f}² - x₀²)

The final distance

         x_{f} = 0.250 +0.220

        x_{f} = 0.4750 m

We calculate the work

          W = ½ 2720 (0.47² - 0.25²)

          W = 215 .4 J

We calculate the strength

          F = k x_{f}

          F = 2720 0.470

          F = 1278.4 N
