Answer:

Explanation:
Given that,
Mass of a crate is 22 kg
It moved up along the 15 degrees incline without tipping.
We need to find the corresponding magnitude of force P. The force P is acting in horizontal direction.
It means that the horizontal component of force is given by :

So, the horizontal component of force is 208.25 N.
Heat within the earth generates convection currents in the mantle. Convection currents represent the circular motion of molten rocks in the mantle driven by heat from the core. This circular motion is what drives the plates and creates the theory of plate tectonics which states that the earth crust is divided into plates that float on the semi-molten mantle below.

<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
