Tom and Jerry start at the same location. Tom is travelling due east at a velocity of 5 m/hr. Jerry is travelling due northwest
Sedaia [141]

Answer:

The distance between them is changing at the speed of 10.16 m/hr

Explanation:

Consider the sketch attached below.

The question is simply asking to calculate the resultant of the two velocities.

To get the angle between them, we simply use the coordinates of the two vectors to determine the angle between them.  

90 + 45 = 135°

from the cosine rule we have

c^{2} = a^{2} + b^{2} - 2abcosθ

c^{2} = 6^{2} +5^{2} - 2 ×6×5×cos 135

c^{2} = 103.426

c = \sqrt{103.426}

c = 10.17 m/hr

Explain how a paleontologist might use relative dating techniques to determine the age of a fossil.
Serggg [28]
As far as I know, radioactive dating is the measure of radioactive substances in a fossil or something. Like the fossils have a radioactive substance in them, it is the only thing that can show how long the fossils been aging, therefore being able to show the date. And thats how radioactive dating works, and that is how a paleontologist uses it

Why are lipids and proteins free to move laterally in membranes?
Rashid [163]

Correct option C) Hydrophilic portions of the lipids are in the interior of the membrane.

Lipids and proteins free to move laterally in membranes because both are inserted into a fluid lipid bi-layer and they are able to diffuse laterally through the membrane.

Lipid Composition of Cell Membranes is a important property of lipid bilayers which is behave as two-dimensional fluids where individual molecules are rotate and move freely in lateral directions

Membrane proteins and phospholipids both are unable to move back and forth between the inner and outer leaflets of the membrane at an appreciable rate. Phospholipids in the lipid bilayer can either move rotationally, laterally in one bilayer, or undergo transverse movement between bilayers.
