Is the allele for a scalloped wing in the fruit fly dominant or recessive to the wild type?

Fb= bouyant force = F2 - F1 = mg

A small sculpture made of brass (density = 8470 kg/m cubed) is believed to have a secret central cavity. The weight of the sculpture in air is 15.76N. When it is submerged in water, the weight is 13.86 N. What is the volume of the secret cavity?

Oh, the density is = 8470

I am assuming I have to find the amount of displacement -- 15.76 - 13.86 = 1.9

I have just now started

sin65 and cos 37?

yes I agree

m1vf1+m2vf2=m1v01+m2v02

Puck A has a mass of 0.025 kg and is moving along the x-axis with a velocity of +5.5 m/s. It makes a collision with Puck B, which has a mass of 0.050 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the angles: Puck A 65 degrees...
