4 0

(distance covered) divided by (time to cover the distance) is SPEED.

(straight-line distance and direction between start-point and end-point) is DISPLACEMENT.

(amount and direction of change in speed) divided by (time for the change) is ACCELERATION.

(amount and direction of change in momentum) divided by (time for the change)  OR  (mass) times (acceleration) is FORCE.

Which statements accurately describe convection in water? Check all that apply. Cold water sinks because it is less dense than w
Tanya [424]

Explanation:

Convection is defined as a process in which movement of particles of fluid is due to heat and less dense fluid rises and more denser (colder) material sink because of the influence of gravity, this results in transfer of heat.

Thus, we can conclude that the statements which accurately describe convection in water are as follows.

  • Cold water sinks because it is more dense than warm water.
  • Warm water rises because it is less dense than cold water.

A glass vessel that can be repeatedly filled with precisely the same volume of liquid is called a pycnometer. A certain pycnomet
White raven [17]

Answer:

density of liquid 0.848 g/ml

Explanation:

from the information given in the question

mass of water = 34.914 - 25.296 = 9.618 g

volume of pycnometer = volume of water

which will be equal to = \frac{ mass}{density}

= \frac{9.618}{0.9970} = 9.646 ml

mass of liquid =33.485-25.296 = 8.189 ml

density of liquid= \frac{mass}{volum\ of\ liquid}

                           = \frac{8.189}{9.646} =0.848 g/ml
