10 Questions
What is work in physics?
Work in physics is the energy transferred to or from an object via the application of force along a displacement.
How is work calculated for a constant force aligned with the direction of motion?
For a constant force aligned with the direction of motion, work equals the product of the force strength and the distance traveled.
When is the work done by a force considered positive?
The work done by a force is considered positive if it has a component in the direction of the displacement at the point of application.
Give an example of a situation where the work done by the gravitational force is positive.
When a ball is held above the ground and then dropped, the work done by the gravitational force on the ball as it falls is positive.
Give an example of a situation where the work done by the gravitational force is negative.
If the ball is thrown upwards, the work done by the gravitational force is negative.
What is CGIAR?
CGIAR is a global partnership that unites international organizations engaged in research about food security.
What are the main goals of CGIAR research?
The main goals of CGIAR research are to reduce rural poverty, increase food security, improve human health and nutrition, and promote sustainable management of natural resources.
How many research centers does CGIAR have?
CGIAR has 15 research centers.
Where are most of CGIAR's research centers located?
Most of CGIAR's research centers are located in the Global South and Vavilov Centers of agricultural crop genetic diversity.
How is CGIAR funded?
CGIAR is funded by national governments, multilateral funding and development agencies, and leading private foundations.
