What else can I help you with?
The 2.5-kg head of an ax exerts a force of 80 kN as it penetrates 18 mm into the truck of a tree The speed of the ax head when it strikes the tree is what per seconds?
To find the initial speed of the ax head, we can use the work-energy principle. The work done by the force of the ax head is equal to the change in kinetic energy. The work done is 80 kN * 0.018 m = 1440 J, and the change in kinetic energy is 1/2 * 2.5 kg * v^2 where v is the speed of the ax head. Equating the two, we find v ≈ 53.2 m/s.
How does food energy travel from one organism to another?
Food energy travels from one organism to another through consumption. When one organism consumes another, it breaks down the consumed organism's organic compounds for energy. This energy is then used by the consumer for growth, reproduction, and other life processes.
Is a cedar tree deciduous or conifer?
The two options are not comparable. The more accurate question is whether a cedar tree is deciduous or evergreen. Deciduous plants any plants that drop their leaves in the fall and are bare during the winter. Evergreens never drop all of their leaves. A conifer is a type of evergreen plant. All conifers are evergreen, but not all evergreens are conifers. But the definition of conifer is:con·i·fer (kn-fr, kn-)n.Any of various mostly needle-leaved or scale-leaved, chiefly evergreen, cone-bearing gymnospermous trees or shrubs such as pines, spruces, and firs.Cedars, or very similar plants called Junipers, are "scale-leaved" as listed in the definition above. So, Cedars are conifer evergreens, as opposed to most Holly plants, for example, which are broad leaf evergreens.A cedar is a conifer and it is evergreen. Not all conifers are evergreen i.e. the larch.
