Answer:
*The increase in thermal energy the maximum emission of radiation changes according to Wien's law
*The increase in thermal energy he intensity of the energy increases significantly, proportional to the fourth power of the temperature
Explanation:
When bodies heat up, the vibrations of their molecules and atoms increase, due to the energy, therefore the internal energy (Temperature) of the body also increases.
The increase in thermal energy relaxes in an increase in body temperature, when this happens the maximum emission of radiation changes according to Wien's law that gives a shift towards the visible as the temperature increases.
Furthermore, the intensity of the energy increases significantly, in a curve described by the Planck expression.
These increases are proportional to the fourth power of the temperature
P = σ A e T⁴
it absorbs energy and releases oxygen and glucose.
The net force on the student is A) -294 N
Explanation:
Neglecting air resistance, there is only one force acting on the student: the force of gravity, which is given by
where
m is the mass of the student
g is the acceleration of gravity
In this problem, we have:
m = 30 kg is the mass of the student
is the acceleration of gravity, where the negative sign means the direction is downward
Substituting, we find the force of gravity on the student:
And since this is the only force acting on the student, it is also the net force on him.

Answer:
the answer is b
Explanation:
because you multiply speed times wavelength
Multicellular organisms, as the name implies, have many types of cells, while unicellular organisms contain just one cell each. Both kinds of organisms reproduce through meiosis or mitosis. Multicellular organisms generally form the higher tiers in the web of life. These living beings, including plants and animals, have a more complex internal layout than unicellular creatures. They rely on specialized cells and cell departments for carrying out specific tasks, such as breaking down food, sending electrical messages and other duties necessary for supporting life. This distinction, called cell differentiation, lets multicellular organisms engage in more complex physical and cognitive tasks than unicellular organisms.In addition to having specialized cells, multicellular organisms have separate organ systems to perform specific tasks. These systems, such as the cardiovascular, digestive and respiratory systems, perform life processes necessary for survival. Digestive systems, for instance, deliver nutrients and energy to organs in the digestive tract, letting them process and digest food. These organ systems also facilitate communications between different types of systems, such as the circulatory and nervous systems.
