Answer:

So the answer is B - Asthenosphere

Explanation:

The earth has four layers; the crust, the mantle, the outer core and the inner core. The Earth’s magnetic field is the combination from the convection it receives from the outer core and the Coriolis Effect. The layer of earth where mantle convection occurs is the asthenosphere. The answer is letter B. The outer core is composed mostly of liquid nickel and iron. It is expected to have that state of metal because it has a higher temperature. The inner core cannot hold much of the magnetic field because of its high temperature and high pressure that exceeds the outer core. The temperature decreases however as the layer goes outwards.

_________ are exchanged or shared during the formation of a chemical bond.

Thepotemich [5.8K]

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds; or through the sharing of electrons as in covalent bonds.

(a) At what height above Earth’s surface is the energy required to lift a satellite to that height equal to the kinetic energy r

Nikitich [7]

Answer:

Explanation:

Gravitational Potential Energy at earth surface $U_1=\frac{GM_em}{R_e}$

Gravitational Potential Energy at height h is $U_2=\frac{GM_em}{R_e+h}$

Energy required to lift the satellite $E_1=U_1-U_2$

$E_1=\frac{GM_em}{R_e}-\frac{GM_em}{R_e+h}$

Now Energy required to orbit around the earth

$E_2=\frac{1}{2}mv_{orbit}^2=\frac{GM_2m}{2(R_e+h)}$

$\Delta E=E_1-E_2$

$\Delta E=\frac{GM_em}{R_e}-\frac{GM_em}{R_e+h}-\frac{GM_2m}{2(R_e+h)}$

$E_1=E_2$ (given)

$\frac{GM_em}{R_e}-\frac{GM_em}{R_e+h}-\frac{GM_2m}{2(R_e+h)}=0$

$\frac{1}{R_e}-\frac{3}{2(R_e+h)}=0$

$h=\frac{R_e}{2}$

$h=3.19\times 10^6\ m$

(b)For greater height $E_1$ is greater than $E_2$

thus energy to lift the satellite is more than orbiting around earth

Q011) The Doppler effect a. occurs when the frequency of sound waves received is lower if the wave source is moving toward you t

inn [45]

Answer:

Option (c) is correct.

Explanation:

The apparent change in the frequency of light due to the relative motion between the source and the observer is called Doppler's effect.

When the source is moving towards the observer which is at rest, the apparent frequency increases and if the observer is moving away the frequency of sound decreases.

It occurs for both light and sound.

So, to explain the blue shift of light in the universe is due to the Doppler's effect of light.
