Answer:
Answer
Explanation:
If the satellite is in perfect orbit around the earth then gravitational pull of the earth on the satellite and moving forward satellite is in perfect balance i.e gravitational pull does not effect the orbit as the velocity of the satellite is good enough to counter the gravitational pull of the earth and inertia makes the satellite move forward with greater velocity, but when its velocity is suddenly reduced, the gravitational pull will counter on the orbiting satellite and it will crash onto the earth.
This is same as in well of death when motorist moves in circular motion inside the well with centripetal and centrifugal forces balanced, suddenly crashes on the ground when velocity of the motorist is not enough to balance forces.
the satellite's mass has no affect on its orbit around the earth rather the mass of the earth is only affecting factor .
Answer:
electrical energy change into heat and light energy.
Answer:
a. Potencia = 250 Watts
b. Tiempo = 333.33 segundos
Explanation:
Dados los siguientes datos;
Energía = 5000 Joules
Tiempo = 20 segundos.
Para encontrar el poder;
Poder = energía/tiempo
Potencia = 5000/20
Potencia = 250 Watts
B. ¿Para saber cuánto tarda una máquina en realizar el mismo trabajo;
Dado: potencia = 15 W
Tiempo = energía/poder
Tiempo = 5000/15
Tiempo = 333.33 segundos
A build up of charges on a sock from a dryer
We know avogadro's number = 6.023 x 10²³
1 amu = 1 atomic mass unit = 1/ (6.023 x 10²³) gm = 1.66 x 10⁻²⁴grams
<span>Now, to convert amu to grams,
131.29 amu = 131.29 x 1.66 x 10</span>⁻²⁴grams
<span>= 2.18 x 10</span>⁻²²<span> grams is the answer</span>
