The magnitude of the tidal force between the international space station (iss) and a nearby astronaut on a spacewalk is approximately

2gmma/r3 . in this expression, m is the mass of the earth, r=6.79×106m is the distance from the center of the earth to the orbit of the iss, m=135kg is the mass of the astronaut, and a=13m is the distance from the astronaut to the center of mass of the iss.



calculate the magnitude of the tidal force for this astronaut. this force tends to separate the astronaut from the iss if the astronaut is located along the line that connects the center of the earth with the center of mass of the iss.

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
