Please help me I'll give brainliest to whoever's answer is right :D

constant, increase, decrease, constant

Explanation:

Not 100% sure but thought I could be of some help. If the arrows are the same size and length it remains constant. If it is longer to the right then it increases (means more force pulling it forward). However if it is longer in the other direction, this is likely to be friction which will slow it down. This is depending on which direction the box is meant to be moved in which is to the right in this case.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
