<span>You do not require a force to keep something moving. You only require a force to get it moving. Or to stop it moving. In your everyday experiences, something you get moving seems to come to a stop after you stop pushing it. It is because there are forces (friction) that make it stop. Without those forces, the object would just keep moving. So this would mean the answer would be True.</span>
Answer:
The displacement is zero miles
Explanation:
The displacement of an object that moves from point A to point B is defined as

Where d is the displacement of the object. The displacement does not depend on the trajectory of the object. It only depends on the linear distance between the end point and the starting point.
In this case we know that the person walks from home to work and then walks from work to home. Therefore, the total displacement is the linear distance between the point where its journey begins and the point where the route ends.
The tour begins on the front porch of your house and ends on the front porch of your house (when you return from work). If we call A to the front porch of the house then the displacement is:

The displacement is zero miles, since the person finishes the journey just where it started (front porch)
Then the time interval during which the rocket engine provides upward acceleration in 2.1s hope this helps have more photos but can’t put them more in brainliest is appreciated
Answer:
At the dimer-dimer interface there might be acting non-covalent forces (van der waals, Hidrogene bridges, hydrophobic forces)
At the monomer-monomer interface there might be covalent forces acting (disulfide bridges).
Explanation:
On the SDS-PAGE application works by disrupting non-covalent bonds in the proteins, and so denaturing them. Therefore, the disulfide bridges won´t be disrupted, so the monomers will remain bounded.
I think it is B as 168/20
