Answer:
Explanation:
K = Kinetic energy
= Perigee speed = 4280 m/s
= Apogee speed = 3990 m/s
= Perigee Distance = 22500000 m
= Apogee Distance = 24100000 m
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of Earth
m = Mass of satellite
In this system the kinetic and potential energies are conserved
The mass of the Earth is
Answer:
D
Explanation:
a weak base is the answer
Polarized light light is unique in that it vibrates mostly in one direction.
Polarized mild waves are light waves in which the vibrations occur in a single plane. The process of reworking unpolarized light into polarized light is called polarization. There are a ramification of methods of polarizing mild.
Polarization is used for differentiating among transverse and longitudinal waves. Infrared spectroscopy makes use of polarization. it is used in seismology to take a look at earthquakes. In Chemistry, the chirality of organic compounds is tested the use of polarization strategies.
Refraction is the change in route of waves that takes place when waves tour from one medium to every other. . Light has a dual nature. as it has waves, sunlight passing via rainstorm makes a rainbow. however, while mild moves a sun mobile, it can provide strength as a series of very small bursts. particles of count number have names together with the proton, electron and neutron.

Answer:
40 metros en 10 segundos.
Explicación:
Una grúa está levantando una caja de 1000 kg atada a una cadena y la caja, que inicialmente está en reposo, aumenta su velocidad en 4 m / s por segundo, por lo que si la región de colocación está a 40 metros de distancia, la grúa tarda 10 segundos en completar el proceso. tarea de movimiento y colocación de la caja. La grúa se utiliza para levantar y mover cargas pesadas, máquinas, materiales y mercancías para diferentes propósitos. Entonces el trabajo realizado por la grúa depende de la velocidad y la distancia de colocación.
Answer:
