Taxidermy, skulls, animal skeletons, deer skeletons. Please, I don't need to know how to spruce up a fresh skull, I need to know how to spruce up an already cleaned, dry, brittle, exposed to the elements for years skull.

how can you tell the luminosity by knowing the magnitude of a star?

ex. A star with a magnitude of -5 and a temp of 24000 degrees C would be found in what category of the HR diagram?

I was able to complete all of the other problems, but this one is much more difficult and I am completely lost..

A squirrel is wandering around a yard. It hops 2.2m at an angle of 74 degrees north of east. Then it scurries 3.1m at an angle of 85 degrees north of west. Finally, it runs 1.7m at an angle of 15 degrees south of west. What are the magnitude and direction for the squirrel's total displacement?

If anyone can help me I'd greatly appreciate it..Thanks!!

i'm stuck on the last 3 questions. please help on any u know thanks.
1. A 20g ball of clay is thrown horizontally at 30m/s toward a 1.0kg block sitting at rest on a frictionless surface. The clay hits and sticks to the block.
a. What impulse does the clay exert on the block?
b. What impulse does the block exert on the clay?
c. Does J(block on clay) = -J(clay on block)?

2.A firecracker in a coconut blows the coconut into 3 pieces. Two peices of equal mass fly off south and west, perpendicular to each other , at 20m/s. The 3rd piece has twice the mass as the other two. What are the speed and direction of the 3rd piece.
3.A 10g bullet is fired into a 10kg wod block that is at rest on a wood table. The block, with the bullet embedded, slides 5.0cm across the table. What was the speed of the bullet?

1. The lower block which is 2kg is pulled on by a rope with a tension force of 20N. the coefficient of kinetic friction between the lower block and the surface is 0.30. the coefficient of kinetic friction between the lower block and the upper block(1kg) is also 0.30. What is the acceleration of the 2.0kg block?


2. Find an expression for the acceleration of m1. Assume the table is frictionlesss.
m1 is a box on a surface being pulled by a pulley toward -->
m2 is a dangling box.

vector A has a magnitute of 5.7 and points at an angle of 125 deg from the x-axis. vector B has a magnitute of 3.8 and points in the same direction as the x axis.

A+B = ([Ax + Bx]), ([Ay+By])
.........= ([5.7cos(180-125) + 3.8cos(0)] , [ 5.7sin(180-125)+ 3.8sin(0)]
.........= (7.1,4.7)

The magnitute of A+B is:
||A+B|| = sqrt( 7.1^2 + 4.7^2)
............= 8.5

did i do this right? and how do i find the angle for the new vector?
