Answer:
Explanation:
There is no external force applied, therefore there is a moment's preservation throughout the trajectory.
<em>Initial momentum = Final momentum. </em>
The total mass is equal to
Where,
mass of ship
mass of fuell expeled.
As the moment is conserved we have,
Where,
Velocity of fuel
Velocity of Space Ship
Solving and re-arrange to 
we have,
Where c is the speed of light.
Therefore the ship be moving with speed
1575 N
Explanation:
Step 1:
Let us consider that 350 J of energy is spent by that person to push a couch to 4.5 m from its initial position.
Let F be the force required and E be the energy spent and D be the distance traveled by the couch from its initial state.
In Physics, Work done = Force / Displaced distance
Step 2:
Let the work done be 350 J and Distance be 4.5 m
Then Force exerted = 
I think the correct answer is hydrolysis. The name <span>of the process that puts adenosine diphosphate (ADP) and phosphate (P) together to reform ATP is called hydrolysis. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
Answer:
Es una constante porque sigue funcionando y debido a la gravedad, tú tendrías que ser tú quien la detenga si está bajando en lugar de hacia arriba.
Explanation:
B- at night
In eyes of the humans, and many other animals there are two types of receptors, the rods, and the cones. The cones have an important role in color vision and they possess different types of pigment which enable color vision.
On the other hand, the rods are more sensitive to light, and they are responsible for black and white vision.
Therefore, an increase in the number of rods can enable the animal to see betther in the dark.
