Answer:
Radiation
Explanation:
The sun heat the earth by the process called radiation.
Radiation is form of heat transfer method just like convection and conduction. Radiation heat transfer does not require medium to propagate, unlike its other two counterparts. There is no medium between earth and sun.
The radiation heat travels through space in form of waves. Like the electromagnetic wave with a specific speed and energy.
Answer:
Greater acceleration of the plates towards each other
Explanation:
If more force is added to the convection currents, there would be a greater acceleration of the plates towards each other.
A lithospheric plate is driven by underlying asthenosphere which is ductile and readily flows. The plate lies on the asthenosphere.
The rate of movement of the asthenosphere determines the rate at which the plate above is moving.
The greater the convection below, the faster the plate moves.
The amplitude of the wave's electric field is times if the intensity of some electromagnetic wave doubles.
- What is electromagnetic wave:
Electromagnetic waves also called EM waves, are waves that are created as a result of vibrations between an electric field and magnetic field.
The formula of Intensity of electromagnetic wave:
- I = 1/2 ( c* ε(0)* E(0)^2 )
where c is speed of light
E is amplitude of electric field
here Intensity of EM waves doubles so,
I' = 2*I
we can say that,
I ∝ E^2
E = sqrt ( I )
E' = sqrt ( 2*I )
hence
E' = * E
so, the amplitude of the wave's electric field is times if the intensity of some electromagnetic wave doubles

Answer:
B.
340meters per second x 2 seconds = 680 meters away
divided by 2coming back = 340
Hope this helps
Explanation:
The cathode and anode are hooked up to an electrical circuit The chemical reactions in the battery causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. Hope this helps :)
