A car is traveling at a constant speed of 60km/h but then changes lanes. Even traveling at a constant speed, the car's velocity is changing. Explain

Yes. Anytime the velocity is constant, the acceleration is zero. For example, a car traveling at a constant 90 km/h in a straight line has nonzero velocity and zero acceleration.

brainlest plz, i really need it

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

0.11 m/s and 0.28 m/s should be correct
