If im not mistaken it is true
Answer:
The two major sources of energy for the rock cycle are also shown; the sun provides energy for surface processes such as weathering, erosion, and transport, and the Earth's internal heat provides energy for processes like melting, and metamorphism
Answer:11.59 J
Explanation:
Given
mass of Particle 
Initially Particle moves towards left 
Final velocity of Particle is towards Right 
According to Work Energy theorem
Work done by all the Forces=change in Kinetic Energy
Work done by Force

Answer:
E = 1000 x
Explanation:
The electric potential and the electric field are related by the formula
dV = - E . dx
Bold represents vectors.
The point represents the scalar product, in this case we calculate the electric field in the x-axis and the potential is also in this axis so the scalar product is reduced to the algebraic product
E = dV /dx
Let's make the derivative
E = - 2ax
Let's replace the values
E = -2 (-500) x
E = 1000 x
Every unit of density is
(a unit of mass) divided by (a unit of volume) .
The one most widely used is [ gram/cubic centimeter ] , but there's no reason that you MUST use this same unit every time you talk about density. You can use (any unit of mass) divided by (any unit of volume) that you want ... the best choices are always the ones that end up with the most convenient number.
Whatever units of mass and volume you decide to use, it's easy for anybody to convert it to [ gram/cubic centimeter ] if they want to.
