Physics
1 answer:
lorasvet [3.4K]3 years ago
3 0

Answer:

E = hv

E = hf

Explanation:

there are basically two equations for energy in light.

E = hf

where E is the energy of the photons. the unit is joules

h = the planck's constant . the unit is joules second

f = frequency of light. the unit is Hertz

E = hv

E is the energy of a particlar quantum under study.

h = planck,s constant which is usually 6.62607555 × 10^-34 js^-1

v = the frequency of the light.

_____ refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
german

Answer:

Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.

Explanation:

Sensation helps us to detect changes in our physical environment.

Sensation occurs in three steps,

  • Sensory receptors, these detect stimuli.
  • Sensory stimuli are converted into electrical impulses to be decoded by the brain.
  • Finally, electrical impulses move along neural pathways to specific parts of the brain wherein the impulses are decoded into useful information.

Therefore, Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.

A capacitor is connected to an ac supply. increasing the frequency of the supply _________ the current through the capacitor
Alja [10]

A capacitor is connected to an ac supply. increasing the frequency of the supply increases the current through the capacitor

A capacitor is a device for storing electrical energy that consists of two insulated conductors in close proximity. The parallel-plate capacitor is a simple example of such a storage device.

A capacitor (also known as a condenser) is a two-terminal passive electrical component that stores energy electrostatically in an electric field. Practical capacitors come in a variety of shapes and sizes, but they all have at least two electrical conductors (plates) separated by a dielectric (i.e., insulator).

Capacitors exist in various shapes and sizes, and their value is measured in farads (F). Capacitors are utilized in both alternating current and direct current systems.

An explosion in a rigid pipe shoots three balls out of its ends. A 6 gam ball comes out the right end. A 4 gram ball comes out t
wariber [46]

Answer:

The third ball emerges from the right side.

Explanation:

This is a conservation of Momentum problem

In an explosion or collision, the momentum is always conserved.

Momentum before explosion = Momentum after explosion

Since the rigid pipe was initially at rest,

Momentum before explosion = 0 kgm/s

- Taking the right end as the positive direction for the velocity of the balls

- And calling the speed of the 6 g ball after explosion v

- This means the velocity of the 4 g ball has to be -2v

- Mass of the third ball = m

- Let the velocuty of the third ball be V

Momentum after collision = (6)(v) + (4)(-2v) + (m)(V)

Momentum before explosion = Momentum after explosion

0 = (6)(v) + (4)(-2v) + (m)(V)

6v - 8v + mV = 0

mV - 2v = 0

mV = 2v

V = (2/m) v

Note that since we have established that the sign on m and v at both positive, the sign of the velocity of the third ball is also positive.

Hence, the velocity of the third ball according to our convention is to the right.

Hope this Helps!!!
