A) GPS monitoring of plate speeds and movements.
Explanation:
The most recent evidence supporting the theory of plate tectonics would be GPS monitoring of plate speeds and movements.
A GPS is a Global Positioning System made up of series of components.
- Plate tectonics theory is the movement of the earth's lithosphere relative to one another.
- The recent advances uses a GPS system to monitor real-time movement of the plates.
- The GPS system is made up of a system of satellite in space that communicates real-times locations to sensors on the earth surface.
- From the sensors, observatory stations can know and duly observe how plates are moving.

The element of a valid contract which is established by getting the signatures of all parties is <u>mutual agreement</u>
<h3>What is an element of a valid contract?</h3>
An element of a valid contract simply refers to that promise made between two or more parties that which allow the courts to make judgement.
Some elements of valid contract are:
- Offer
- Acceptance
- Consideration
- Intention to create legal relation
- Certainty and capacity.

Answer:
From question (a) and (b) the pendulum motion is perpendicular to the force so the normal force will do no work and the tension in the string of the pendulum will not work
And 
so
c
An example will be a where a stone is attached to the end of a string and is made to move in a circular motion while keeping the other end of the string in a fixed position
d
A dog walking along a surface which has friction, here the frictional force would acting in the direction of the motion and this would do positive work
