Answer:
C. The amount of force applied to rock one was half the amount of force applied to rock two during the eruption.
Explanation:
A force is an agent which changes the state of an object well applied to it. Second Newton's law of motion state's that;
F = ma
where F is the force, m is the mass of the object and a is the acceleration of the object.
In the given question,
Mass of first rock = 10 kilograms
Mass of the second rock = 20 kilograms
Acceleration of the two rocks = 600 m/
Thus,
Force on the first rock = ma
= 10 x 600
= 6000 N
Force on the second rock = 20 x 600
= 12000 N
Therefore, it can be observed that the amount of force applied to rock one was half the amount of force applied to rock two during the eruption.
Answer:
hope this helps love! There are three methods of heat transfer: conduction, convection, and radiation. Cooking of food usually uses a combination of these methods. Conduction transfers the heat using direct contact; food is heated directly in a metal pan, in a liquid, or surrounded by air. ... The heat from the water is transferred to the egg.
Explanation:
When the water is heated, thermal expansion happens so the particles move farther apart and then the hot water moves up because it is less dense then the colder water. ... Convection is happening because when air is heated by the fire, the air becomes less dense and moves up because denser things sink.
They compress or expand depending on amount of pressure or depending on the temperature
Using the theorem of kinetic energy
1/2mVf² - 1/2mVi²= WF + Wp, Wp=0
WF = F. AB, AB=5m and F= 40N, m=20kg
so the final kinetic is KEf= 1/2mVf² = WF =<span>F. AB= 40*5=200J
</span>
the final velocity is 1/2mVf² <span>=200, implies Vf= sqrt(20)=2sqrt(5)m/s</span>
