A piece of metal. I believe it is a piece of metal.
Answer:
Option D
A type I error is making the mistake of rejecting the null hypothesis when it is actually false.
Explanation:
Error type I is usually represented by alpha symbol and type I error entail making a mistake of rejecting the null hypothesis when it's actually true. Type II error on the other side involves making a mistake of failing to reject null hypothesis when it is actually false. The statement in option D is false because it contradicts the definition of type I error above hence the only false statement in relation to hypothesis testing is option D, A type I error is making the mistake of rejecting the null hypothesis when it is actually false.

Explanation:
Let d distance between the asteroid and space tug
So;d=Xtug+Xspace
Xtug=VtT+0.5atT^2
Xspace=VsT+0.5asT^2
Since Vt=Vs=0 initial velocity
Then
d=0.5(atT^2+asT^2)
T^2( at+as)=2d
T=√(2d/at+as)
But force F = mass M*acceleration a
Hence at=Ft/mt ,as=Fs/ms
But note Ft=F=Fs since the Same force acts on it
Hence T=√( 2d/F(1/mt+1/Ms))
T=√(2*493/366(1/3460+1/6430)
T=√(986/0.1627)=√(6060.195)=77.8s
