Answer: A 20kg Stone traveling an 10 m/s
Explanation:
The Formula for Kinetic Energy is KE = 0.5 x mv², using this equation you can then find the item with the most Kinetic Energy in Joules (J) 0.5 x 20 x 10 = 200 Joules.
Answer:
pH = 2,4
Explanation:
pH is defined as a measure of acidity or alkalinity of a solution based on H⁺ concentration
The HCl dissociates in water thus:
HCl → H⁺ + Cl⁻
That means that moles of HCl are the same than H⁺.
0,35gHCl
= 9,6x10⁻³ moles HCl ≡ moles H⁺
H⁺ molarity is: 
= 3,84x10⁻³M
As pH = -log [H⁺]
<em>pH = 2,4</em>
I hope it helps!
Convection currents in the mantle are what causes the movement of tectonic plates. As the extremely hot molten material from the mantle rises toward the crust, it cools enough to become denser and sink back into the hotter area of the mantle.
Answer:
energy is the capability or ability to do work
Explanation:
An object that possesses energy can exert a force on another object. When this happens, energy is transferred from the former to the latter. The second object may move as it receives energy and therefore does some work. Thus, the first object had the capacity to do work.
