Answer:B
Explanation:
Given
mass of sledge=82 kg
Force on sledge=160 N
degree![=15^{\circ}](https://tex.z-dn.net/?f=%3D15%5E%7B%5Ccirc%7D)
force has two component sin and cos
Normal reaction ![=mg-F\sin \theta](https://tex.z-dn.net/?f=%3Dmg-F%5Csin%20%5Ctheta%20)
![N=82\times 9.8-160\sin 15](https://tex.z-dn.net/?f=N%3D82%5Ctimes%209.8-160%5Csin%2015)
![N=803.6-41.41=762.19 N](https://tex.z-dn.net/?f=N%3D803.6-41.41%3D762.19%20N)
Actually yes because my sis got a bruse in her body!
I think its 60. I think you would subtract 144-84 to get the mass of the vinegar molecule.
No, you may have similar genetic material but not identical. You can have identical genetic material to your brother or sister if they are identical to you but not your parent because your genetic material consists of two people who have no relation to each other genetic material wise.
