2.1 Draw a labelled force diagram which shows all the forces acting on the block.
2.2
Calculate the gravitational force of the block when the force in the rope is 8 N.
Activity 3:
A block, of mass 20 kg, is pulled upwards by force F along a plane indine at 30° to the horizontal. It
accelerates along the incline plane at 2 m-s'. The surface of the incline exerts a friction forc
e on the
block.
3.1
Draw a diagram showing all the forces acting on the block (force diagram) as it move up the
incline. Also draw a free-body diagram for the block. Represent the forces on the Cartesian
plane and resolve the gravitational force into components.
Calculate the component of the gravitational force exerted on the block parallel to the
Incline
3.2
3.3
Calculate the normal force.
3.4
Calculate the friction force If the magnitude of is equal to 200 N.
3.5
Calculate the coefficient of kinetic friction for the block.​

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

is has three carbons, so the answer is propylamine.
