When light energy hits the retina, the retinal changes from a _____ to a _____ configuration.
gayaneshka [121]

Answer:

Cis, Trans.

Explanation:

Rhodopsin also known as visual purple, pigment which contains sensory protein that helps to convert light into an electrical signal. Rhodopsin present in wide range of organisms from bacteria to vertebrates.

Rhodopsin is composed of opsin, and 11-cis-retinaldehyde which is derived from vitamin A. When the eye contact with light the 11-cis component converted to all trans-retinal, which results in the changes in configuration fundamental in the rhodopsin molecule.

A spring is used to launch a coffee mug. The 20cm long spring can be compressed by a maximum of 8cm. The mug has a mass of 350 g
Zepler [3.9K]

Answer:

7503.13 N/m

Explanation:

Use principle of conservation of energy.

Here, energy stored in the spring due to compression shall be utilized in attaining the potential energy of the mug.

Given that,

Length of the spring = 20 cm = 0.20 m

Compression, x = 8 cm = 0.08 m

mass of the mug, m = 350 g = 0.35 kg

h = 7 m

use the expression for energy balance -

(1/2)*k*x^2 = m*g*h

=> k = (2*m*g*h) / x^2

input the values

k = (2*0.35*9.8*7) / 0.08^2

= 7503.13 N/m

What is the kinetic energy of a 26 kg eagle flying at an altitude of 65 m at a speed of 19 m/s?
sweet [91]

Answer:

4693 J

Explanation:

The kinetic energy of the eagle is given by:

K=\frac{1}{2}mv^2

where

m is the mass of the eagle

v is the speed of the eagle

In this problem, m = 26 kg and v = 19 m/s. Substituting into the formula, we find

K=\frac{1}{2}(26 kg)(19 m/s)^2=4693 J

As we can see, the altitude of the eagle is not relevant for the calculation of the kinetic energy.

A 0.4 kilogram sample of aluminum at 115 degrees Celsius is put into a container containing 0.5 kilograms of water at 15 degrees
AlladinOne [14]

The heat liberated by the aluminium container would be equal to heat absorbed by the water.


According to the first law of thermodynamics for a closed system the total energy of the system is always conserved. Therefore the energy liberated by the aluminium container will completely absorbed by the water untill they both come to thermal equilibrium.
