The correct answer is letter D. A knife would most likely cause this blood spatter pattern because of the direction of the force that was inhibited on the weapon and the victim. The direction of the spatter will also depend on the body part that was hit by the weapon.

Need answer ASAP!! The specific heat capacity of metal A is twice that of metal B. Based on
AURORKA [14]

Answer:

last choice

Explanation:

Specific heat of a metal is    j/kg-c

It says nothing about melting point or heat of fusion

A = twice B   =  2 * j/kg-c       B = j/kg-c

 if   j is constant and mass is the same we can write this more like

    A = 2 /C       and    B = 1/C

  or    A ~  C/2      and   B~  C

now you can see that the temp change in A   will be 1/2   that of B
