Answer:
F=m(11.8m/s²)
For example, if m=10,000kg, F=118,000N.
Explanation:
There are only two vertical forces acting on the rocket: the force applied from its thrusters F, and its weight mg. So, we can write the equation of motion of the rocket as:
Solving for the force F, we obtain that:
Since we know the values for a (2m/s²) and g (9.8m/s²), we have that:
From this relationship, we can calculate some possible values for F and m. For example, if m=10,000kg, we can obtain F:
In this case, the force from the rocket's thrusters is equal to 118,000N.
Answer:
1.29 m
Explanation:
Net force acting on the dog, will be given by
where m is mass and g is acceleration due to gravity
Since the work done by the net force against the ground equals the final potential energy
Height which the dog can jump,
H=0.6+0.44=1.04 m
Total height to reach=Height to jump+ half height of the dog
=1.04 m+0.5(0.5 m)=1.29 m
Answer:A satellite maintains its orbit by balancing two factors its velocity the speed it takes to travel in a straight line and the gravitational pull that Earth has on it. A satellite orbiting closer to the Earth requires more velocity to resist the stronger gravitational pull.
Explanation:
A deep zone.........................
It gets into the atmosphere through evaporation, it wafts round as clouds and water vapor, then eventually precipitates out somewhere as rain or snow. This enters it into the biosphere, because every living thing on Earth needs water, and obviously in to the hydrosphere because... water is water. As moving water (streams, glaciers, etc.), it weathers and erodes the geosphere (the lithosphere is part of the geosphere). Deep down where rocks become sedimentary or metamorphosed, water also influences what kind of rock you get (as is also the case with cooling lava, but that's basically water at its first stage of entering the cycle).
