Scientists must have an unbiased type of investigation. These type of science requires three major characteristics for it to be functional and sticked to the truth: they must be impartial, accuarate and truthful. Without these characteristics there is no way forensic science must be treated as science.
Answer:
The horizontal speed of a projectile is constant for the duration of its flight. This is because, once launched, there are no horizontal forces acting on the projectile (air resistance is usually ignored because it is very small) so horizontally the projectile will travel at a constant speed. For any calculations involving the projectile's horizontal motion, we use
distance=speed×time
d=vt
Impulse is the interval of a force ,f,over the time interval ,t,for which it acts
Formula p=f t
Momentum is the quantity of motion of a moving body measured as a product of its mass and velocity
Formula p=m v
P=momentum
M=mass
V=velocity
Yes, in a classical model of the singly-ionized helium atom, a single electron orbits the nucleus.
<h3>What is singly ionized helium?</h3>
Singly ionized helium is an atom that has lost one electrons from its outermost shell. We consider its remaining electron like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom which is the number of protons in the nucleus so the nucleus charge on singly ionized helium is -1.

Answer:
I don't know this for sure, but I think its because they need to be able to sit in their seats without flying in the air.
