Electric Current: The rate of flow of charge is current. An ampere is the flow of one coulomb through an area in one second.
The pressure on the inner ear is calculated by subtracting the pressure of the atmosphere of the bottom from the top, so calculating this will give us: 1.010x10^5 - .998x10^5 = 1200Pa outward which would be letter A.
And so the net force would be now calculated as P*A = 1200Pa*π*(0.40x10^-2m)^2 = 0.0603N
<h3><u>Answer;</u></h3>
Each will reflect at an angle equal to its angle of incidence.
<h3><u>Explanation;</u></h3>
- <em><u>When light hits a surface or a boundary it bounces of the surface a phenomenon called reflection, which is a property of waves. Reflection occurs such that the incidence angle is equal to the angle of reflection.</u></em>
- Reflection of light depends on whether the surface is smooth or rough. When the light hits a smooth surface it bounces off the surface and all the rays of light moves in the same direction, this type of reflection is called specular reflection.
- On the other hand , when right rays hits a rough surface the rays bounces off the surface and the rays move in different directions, a type of reflection called diffuse reflection.
<u>Answer:</u> The energy released in the decay process is 
<u>Explanation:</u>
The equation for the alpha decay of Ra-226 follows:
To calculate the mass defect, we use the equation:
Mass defect = Sum of mass of product - Sum of mass of reactant
We know that:
Putting values in above equation, we get:
(Conversion factor: 1 kg = 1000 g )
To calculate the energy released, we use Einstein equation, which is:
Hence, the energy released in the decay process is
Answer:
tectonic plates move in opposite direction
Tectonic plates are not necessarily moving in opposite directions, but if there directions are different they form plate boundaries. If they were moving in the same direction they would become the same plate. The more opposite the direction, the more obvious the fault.
Examples of plate boundaries:
Divergent: moving away from each other - mid-Atlantic ridge
Convergent: moving towards each other - the Himalayas (Indian plate subducting under the Eurasian plate forcing up the mountains)
Transform: sliding laterally along each other - San Andreas fault
