Answer:
8.2 m/s
Explanation:
radius (r) = 1.3 m
coefficient of friction (u) = 0.19
acceleration due to gravity (g) = 9.8 m/s^{2}
for the passengers to remain stuck on the wall, the normal force must be equal to the centripetal force (while considering the coefficient of friction).
normal force = centripetal force x coefficient of friction
mg = x u
g = x u
v =
v =
v = 8.2 m/s
the minimum speed the passengers can have to stick to the wall = 8.2 m/s
Explanation:
because the moon has less mass than earth, the force due to gravity at the lunar surface is only about 1/6 that on earthso,the weight of a body on earth is 6×5N =30N
Here's an unorthodox approach that you might try:
READ each choice and think about it for a coupla seconds !
<span>A) diversity improves an established ecosystem.
No. The results were not an improvement.
B) genetic variation leads to the formation of a new species.
No. There's no mention of genetic variation or new species in the story.
C) the introduction of non-native species upsets a balanced system.
YES ! That's exactly what is described in the story.
D) changing in one part of a system does not affect other parts of the system.
</span>
No. A very great effect on the system is described.
Answer:
It is located at the point where circles intersect on a map.
Explanation:
The name 'EPICENTER' was formed by a seismologist from Ireland can Robert Mallet.
An epicenter of an earthquake can be defined as the exact point in the center where as earthquake originated from.
An epicenter of an earthquake can also be defined as the point that is located directly above the focal point of an earthquake.
In other to be able to accurately determine the exact place where an earthquake happens, seismologist try to find out the distance of the earthquake from at least three seismic recording stations. The distance of the earthquake is obtained from a an equipment used by seismologist called seismograph. After obtaining the values if this distance, circles with the right radius are then drawn around each station. The point where the three circles meet or intersect shows us the earthquake's epicenter.
