Answer:
Base
Explanation:
anything with a pH between 0-6 is an acid. pH of 7 means neutral. 8-14 means it is a base
hope I helped :)
Answer:
The time taken is 6.7 min
Explanation:
Using the linear momentum conservation theorem, we have:
when she was 60.4m from the shuttle, she has zero speed, so the initial velocity is zero.
That is 0.15m/s in the opposite direction of the camera.
the time taken to get to the shuttle is given by:
They should see if there are any sources of bias
Explanation:
The best way to ascertain the reliability of the claim in the article is to see if there is a source of bias.
A source of bias in the article can tell a lot about how reliable and trustworthy the article is. It will also give room to more research about the claim in the article from other sources.
It is possible for some elements of bias to be introduced into a set of observation due to preference and choices.

Answer:B. The superposition of waves from the primary source and reflected waves produced regions of constructive and destructive interference.
Explanation: Tsunami is described as several waves originating from a water body mainly an ocean caused by Large scale earth movements taking place under the sea.
Superimposition of wave is the movement of one wave on another,it can be constructive or destructive.
Constructive interference is a wave interference that take place causing the Crest of one wave to align with that of another wave leading to high amplitude.
Destructive interference is a wave interference that take place causing the Trouph of one wave to align with the crest of another wave leading to low amplitude wave.
Answer:
a) 145.6kgm^2
b) 158.4kg-m^2/s
c) 0.76rads/s
Explanation:
Complete qestion: a) the rotational inertia of the merry-go-round about its axis of rotation
(b) the magnitude of the angular momentum of the child, while running, about the axis of rotation of the merry-go-round and
(c) the angular speed of the merry-go-round and child after the child has jumped on.
a) From I = MK^2
I = (160Kg)(0.91m)^2
I = 145.6kgm^2
b) The magnitude of the angular momentum is given by:
L= r × p The raduis and momentum are perpendicular.
L = r × mc
L = (1.20m)(44.0kg)(3.0m/s)
L = 158.4kg-m^2/s
c) The total moment of inertia comprises of the merry- go - round and the child. the angular speed is given by:
L = Iw
158.4kgm^2/s = [145kgm^2 + ( 44.0kg)(1.20)^2]
w = 158.6/208.96
w = 0.76rad/s
