Answer:

Darwin's theory of natural selection lacked an adequate account of ... Darwinian principles now play a greater role in biology than ever before, .... Sadly, even if Mendel had lived to see the rediscovery of his work, he probably .... evolutionary forces are acting, a genetic equivalent to Galileo's law of inertia.

I don't understand how to find the frequency and period of wavelengths. Can anyone help me?

nordsb [41]

Frequency of a wave =

   (speed of the wave) divided by (wavelength)
or
   (1) divided by (period of the wave) .

Period of the wave =

   (wavelength) divided by (speed of the wave)
or
   (1) divided by (frequency of the wave) .

What is simple machines and it type.I need it today please

raketka [301]

Simple machines are tools, devices or objects that are used to make work easier.

TYPES OF SIMPLE MACHINES.

Levers
Inclined Plane
Wedges
Screw
Pulley
Wheel & Axle

THE LEVERS

A lever is simply a plank or ridge beam that is free to rotate on a pivot.

PARTS OF A LEVER

Load
Effort
Fulcrum or pivot

CLASSES OF LEVERS

THE FIRST CLASS LEVER

In this class, the FULCRUM is between the EFFORT and the LOAD. The mechanical advantage is more if the load is closer to the FULCRUM. Examples: seesaws, boat oars and crowbars.

THE SECOND CLASS LEVER

In this class, the LOAD is between the EFFORT and the FULCRUM. The mechanical advantage is more if the LOAD is closer to the FULCRUM. Example: wheelbarrow.

THE THIRD CLASS LEVER

In this class, the EFFORT is between the LOAD and the FULCRUM. The mechanical advantage is more if the EFFORT is closer to the LOAD. Example: garden shovel.

THE INCLINED PLANE OR RAMP

An inclined plane is a simple machine with a sloping surface. It makes it easier for us to move objects from lower grounds to higher grounds.

WEDGES

A wedge is simply a triangular tool, often made of wood, stone, metal or plastic. It is thick at one end and tapers to a thin or sharp edge at the other end. Examples: knife, axe, doorstopper, nail, blade on the snow plough or farmer grader.

PULLEY

A pulley is simply a wheel with a groove in it, and a rope in the groove. It is used to lift heavy objects from the ground to high places.

WHEEL & AXLE

Involves two circular objects joined at the center. It works when force is applied to the wheel or when force is applied to the axle. Example: door knob.

Si: A + B = C – D es una ecuación física donde A, B, C y D son magnitudes físicas entonces [ A ] = [ B ] = [ C ] = [ D ]

PilotLPTM [1.2K]

Answer:

$[A] = [B] = [C] = [D]$ por el Principio de Homogeneidad Dimensional y el uso de operaciones de adición y sustracción.

Explanation:

Por el Principio de Homogeneidad Dimensional, A, B, C y D deben tener las mismas magnitudes físicas para la realización de operaciones de adición y sustracción. Es decir:

$[A] + [B] = [C] - [D]$ , donde $[A] = [B] = [C] = [D]$

When using science to investigate physical phenomena, which characteristic of the event must exist?

Vesna [10]

The correct answer is B. Measurable

Explanation:

The use of science to investigate a phenomenon implies using measurements and observations to better understand a phenomenon or test a hypothesis. Moreover, science focuses on natural phenomena that can be objectively studied through measurement instruments such as a thermometer, balance, hydrometer, etc.

In this context, for a phenomenon to be studied by science this needs to be measurable because the use of precise instruments as wells as numbers allow scientist to analyze and understand a phenomenon. Moreover, phenomena that depend on personal perspectives and cannot be measure is considered as non-scientific.
