Positive - Friction allows us to create heat in a desperate situation, like being lost in the woods. If we didn't have friction, we would probably freeze to death.
Negative - Friction can also cause unwanted fires, such as forest fires. If friction didn't exist, we wouldn't have these.
I think it is false, because why would is be stronger in a different state?
Pelvic girdle
In human anatomy, the pelvis is a complex of bones that connects the trunk and the legs, supports and balances the trunk, and houses and supports the intestines, the urinary bladder, and the internal organ. It is sometimes referred to as the bony pelvis or the pelvic girdle.
One is located on the left side of the body and the other is located on the right. They come together to make the pelvic girdle, a portion of the pelvis. The hip bones are attached to the upper portion of the skeleton at the sacrum.
The pelvic girdle's main function is to support the upper body's weight while seated and transfer that weight to the lower limbs while standing. For the muscles in the trunk and lower limbs, it functions as attachment point.

a.) Relative velocity = velocity of car B - velocity of car A
= 19 - 14
= 5 m/s
Hope this cleared your doubt, feel free to ask any question regarding this and have a nice day ahead! :)
Answer: 10kg
Explanation:
force applied by Ahmad = 100 N
box's acceleration = 10 m/s
mass of the box = ?
Recall that Force is the product of mass of an object by the acceleration by which it moves.
i.e Force = mass x acceleration
100N = mass x 10m/s
Mass = 100N / 10m/s
Mass = 10kg
Thus, the mass of the box is 10kg
