Answer:
The net force acting on the body is 10N directed to the left.
Explanation:
Magnitude of force to the right = 5N
Magnitude of force to the left = 15N
Net force acting on the object and in what direction;
Solution:
It is the vector sum of all forces acting on a body. This net force is the single force that will replace the forces acting on a body;
For the problem;
Net force = Force to the left + Force to the right
Let us take left to be negative and right to be positive;
Force to the left = -15N
Net force = -15N + 5N = -10N
The net force acting on the body is 10N directed to the left.
Answer:
y^16
Explanation:
who need to add the exponents only
7 + 9 = 16
therefore, the answer is y^16
Change of position and time
Answer:
∈=
Explanation:
Using the Gauss Law to determine the electric field of the net flux at the surface of the nucleus
∈
The P is the charge density and 'Eo' is the constant of permittivity in free space
to find P
So replacing
∈
∈=
Mantle convection
Explanation:
The driver of moving plates is the mantle convection.
Convection is a heat transfer process that involves the movement of fluids from one place to another.
How does convection occur in the mantle?
- Part of the mantle known as the asthenosphere is a hot liquid. It moves slowly and does not readily flow.
- Over riding the asthenosphere is the brittle lithosphere made up of the upper mantle and the entirety of the crust.
- The asthenosphere is at a higher temperature compared to the lithosphere on top.
- In order to achieve stability and thermal equilibrium, the asthenosphere rises to the surface whereas the dense and cold lithosphere sinks down.
- This way a convective cell is set up.
- Hot materials rises to the surface because they are light whereas cold materials on the surface sinks into the asthenosphere.
- Through this the plates moves.
