What is the only part in our body we do not stretch?

Answer:

Increase

Explanation:

The best way for me to visualize the relation between wavelength, frequency, and energy is to think about actual ocean waves. Wavelength is a measure of the distance between two equivalent points on consecutive waves (think wave peak to wave peak). Lets say you are building a sand castle and want to see how many waves hit your castle over a period of 10 seconds. If the distance between each wave is 10 ft and the wave is traveling at 1 foot per second then you will only have one wave hit your castle. If the wavelength is 1/2 that (5 ft) then you will have 2 waves hit your castle in the same amount of time. This is the same concept behind waves in physics. The smaller the distance between each wave, the more waves and therefore more energy that will be delivered.

Answer:

Joule’s law of heating states that when a current ‘i ' passes through a conductor of resistance ‘r’ for time ‘t’ then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time.

H = i 2 rt

The reason behind the heat produced is the collision of the free electrons with the lattice ions or atoms while accelerating in presence of the external electric field.

we know that

volt= work done/ total charge or v = w/q

from this we get w= vq

we know that current i = q / t

so q = it

putting this in prev equation

we get w = vit

from ohms law v = ir

putting it in prev eq we get

w = irit = i2rt joule as work is stored as heat soH = I2RT Joules

if a current carrying conductor having resistance (r) gets heated by to passing of current (i) for time (t) and the heat thereby produced be H

joules law states that

H propotional to i^ 2 when r and t are constant

H propotional to r when I and t are constant

H propotional to t when r and I constant

Se realizan estudios en tres áreas: a) Procesos de transformación de la energía, b) Almacenamiento de la energía, c) Gestión inteligente entre consumo y generación.

Explanation:

Actualmente, se están realizando estudios en principalmente en tres áreas cruciales: a) Procesos de transformación de la energía, b) Almacenamiento de la energía, c) Gestión inteligente entre consumo y generación.

a) Se están desarrollando nuevos materiales que permiten mayor eficiencia entre la energía recibida y la energía eléctrica, además de una mayor durabilidad frente a las condiciones ambientales. Esto implica el mejoramiento del desempeño de las tecnologías basadas en las energías renovables y limpias, acortando su brecha con las energías no renovables.

b) Se están desarrollando nuevos materiales que garanticen una mayor densidad energética y mayor durabilidad, significando baterías más compactas, con mayor capacidad y más competitivas económicamente.

c) Se están desarrollando estrategias de control inteligente a tiempo que permite sincronizar el consumo y la generación, además de posibilitar el flujo bidireccional de la energía a través de una red inteligente (smart grid) e integrar mejor las fuentes renovables dentro de la matriz energética.

Answer:force required to lift the load = 500N

Explanation:

Mechanical advantage for a lever is given by the formulae

= force output/force input

or

Mechanical Advantage = Load / Effort

where

Force output  / Load= 800 N

mechanical advantage = 1.6

Force input / Effort =??

Force input=  Force output /Mechanical advantage

= 800N / 1.6

=500N

OR

Effort = Load/ Mechanical Advantage = 800/ 1.6 = 500N

Answer:

the watt is a unit of power

The symbol W denotes the work done and m is the mass and g is the acceleration due to gravity. If m is in Kg and g has a unit of m/s². Then the unit Kg m/s² is equal to one joule J. That is the unit of work done.

Work done in physics is the dot product of force and displacement. Work done of one joule is equal to the force of one newton, exerted by an object of mass m and acceleration a.

Thus we have F = Ma.

If the acceleration is replaced by acceleration due to gravity g, then force of one Newton is mg, that is the product of mass and acceleration. Force is an external agent act on a body to change its state from rest or motion.

If the force applied causes a displacement of the object, then a work is done on the body. Let the mass is taken in Kg and acceleration due to gravity is in m/s², then one newton  is  Kg m/s² is equal to one joule J. Hence, W has the unit of Kg m/s² or J.

Explanation:

Impulse = change in momentum = force x change in time

50 x 0.02 = 1

If a baseball is hit by a bat with a force of 50N during a time interval of 0.02s. Then the impulse on the baseball is 1 N s.

An impulse is a quantity that measures the change in momentum of an object. It is defined as the product of force and time, and it is measured in units of Newton seconds (N s) or kilogram meters per second (kg m/s). The impulse experienced by an object is equal to the change in momentum that occurs when a force is applied to it for a specific period of time.

Impulse is practically applied in various areas of physics and engineering. Here are a few examples:

Sports: Impulse is a crucial factor in many sports, especially those that involve hitting or throwing objects. In sports like baseball, cricket, and golf, the force and time of impact determine the ball's momentum and trajectory.

Transportation: The impulse experienced by vehicles during a collision is used to determine the forces that act on the occupants. This information is used to design safety features such as airbags and crumple zones.

Engineering: In mechanical engineering, impulse is used to design machines that can produce large forces over short periods. For example, hydraulic presses use a large force over a short period to shape metal or other materials.

Physics: Impulse is a fundamental concept in physics, particularly in the study of collisions and the conservation of momentum. The impulse-momentum theorem is a fundamental law of mechanics that relates the change in momentum of an object to the impulse applied to it.

Here in the Question,

The impulse on the baseball can be calculated using the formula:

Impulse = Force x Time

Given that the force is 50 N and the time interval is 0.02 s, the impulse can be calculated as follows:

Impulse = 50 N x 0.02 s

Impulse = 1 N s

Therefore, the impulse on the baseball is 1 N s.

Explanation:

(1) Given that,

A charge, [tex]q=3\times 10^{-7}\ C[/tex]

Electric field, E = 27 N/C

We need to find the force acting on the charge. The force on the charge is given by :

[tex]F=qE\\\\F=3\times 10^{-7}\times 27\\F=8.1\times 10^{-6}\ N[/tex]

So, the force acting on the charge is [tex]8.1\times 10^{-6}\ N[/tex]

(b) Charge, [tex]q=5\times 10^{-6}\ C[/tex]

Force, [tex]F=2\times 10^{-4}\ N[/tex]

Let E be the electric field.

[tex]E=\dfrac{F}{q}\\\\E=\dfrac{2\times 10^{-4}}{5\times 10^{-6}}\\\\E=40\ N/C[/tex]

So, the electric field is 40 N/C.

Answer: Budding is one of the methods of asexual reproduction in organisms.

Explanation:

The asexual reproduction is the process in which new organisms are produced from the parent organism without the formation of gametes. The budding is one of the methods of asexual reproduction in which from a mature organism a bud develops as an outgrowth. The bud obtains the nutrition from the parent organism and increase in size. On maturity the bud dissociate or detach from the parent organism and lives as separate individual organism. Budding can be seen in the case of Hydra, and Yeast.
