Supposed two objects attract each other with a gravitational force of 16units. If the mass of both object were triple and the distance between object were double.
What will be the resulting force between the two objects

During your summer internship for an aerospace company, you are asked to design a small research rocket. the rocket is to be launched from rest from the earth's surface and is to reach a maximum height of 910 m above the earth's surface. the rocket's engines give the rocket an upward acceleration so it moves with acceleration of 16.0 m/s2 during the time t that they fire. after the engines shut off, the rocket is in free fall. ignore air resistance.

Which of the following is not a part of the respiratory system? a. pharynx b. trachea c. pancreas d. larynx

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
