What is the definition of pe
Reika [66]
The definition of P.E which stands for physical education is instruction that ranges in many areas to improve performance and management in athletic games. The definition of sports is an activity that requires skill and physical exertion of a team or an individual competing against others for fun or entertainment. I believe these are similar because without physical education kids cannot excel in their sports. P.E will help prepare them for this.However they are different because sports are solely focused on one topic and try to perfect that, physical education gives you many different things to work on.

Which tuning fork test evaluates conductive and sensorineural hearing loss in both ears at the same time
Flura [38]

The Rinne and Weber tests are frequently used to detect conductive and sensorineural deafness.

Another test to assess conductive and sensorineural hearing impairments is the Weber test. When sound waves cannot flow from the middle ear to the inner ear, conductive hearing loss results.

This may be brought on by issues with the eardrum, middle ear, or ear canal, such as an infection. A helpful, quick, and easy screening test for determining hearing loss is the Weber test.

The test can identify unilateral sensorineural and conductive hearing loss. Conduction hearing is mediated by the middle and outer ear. A tuning fork is used in the Weber test, a hearing screening procedure. It can identify unilateral sensorineural hearing loss and unilateral conductive hearing loss in the middle ear.

Serjik [45]

Answer:

Option B

It converts light into electric current

Explanation:

A photometer is a device used to measure illuminance

Its principle of operation hinges on the conversion of light into electric current, using photoresistor or any other light sensitive device such as  a photodiode.  This is so that it can be read off easily by any other device.

A Photoresistor is a device that changes the flow of current through it when it is exposed to light rays.  A photometer works by irradiating a photo resistor, which then converts the light rays incident on it to electric current.
