Answer:7.2kgm/s
Explanation:
Answer:
7,200 g · m/s
Explanation:
Momentum formula:
p = mv
p = momentum
m = mass
v = velocity
p = (18)(400)
p = 7,200 g · m/s
Answer:
The higher the better. Inside the atmosphere since sound cant travel without a atmosphere
Explanation:
Answer:
higher evaluations = faster sound travel
B They evolve more quickly than native species.
C They have higher reproductive rates than native species.
D They have no population controls such as predators.
Answer:
Option (C)
Explanation:
Invasive species usually refer to those species that are new to an ecosystem and cause a great impact on the native species. It also affects the ecosystem, economy and the health of human beings. Examples of some invasive species are zebra mussels, killer algae, green crab and Asian carp.
These species are much stronger than the native species and they have the ability to grow at a much faster rate, increasing their population. This increasing rate of population creates a problem for them to survive in a new location.
Thus, the most appropriate answer is option (C).
Answer:
D
Explanation:
The other species had evolved to be able to survive the predators of the area over the years
Answer:
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
hope it helps:)
Answer:
Then number of electrons is equal to number of protons
Explanation:
Since protons are positive and electrons are negitive, they cancel each other.
HENCE THEY ARE NEUTRL

The question says interval and not interval(s) so that’s why it’s making me think it may be the latter.
Answer:
Q-R is correct
Explanation:
A constant velocity means a velocity that is not changing.
The velocity is increasing (changing) in O-P, P-Q and R-S.
Since the Q-R segment is a horizontal line, the velocity stays the same. If you imagine the graph's velocity y-axis is labelled, it might be easier to think about.
Answer:
The velocity is constant only in the Q-R interval.
Explanation:
The graph shows the velocity over time. In the Q-R interval the velocity is equal all over the interval, that is, it is constant. In the other intervals, the velocity increase with some rate, so it is not constant.
