Answer:
B. point on the surface directly above the earthquake
Explanation:
The earthquake involves the propagation of waves through the inner part of the earth due to natural or artificial processes. This majorly leads to the vibration of the earth crust of the affected region as the waves propagates. Thereby, causing sometimes the a violent break up of the surface of the earth from within.
Therefore, the focus of an earthquake is majorly called its epicenter, which is a point on the surface directly above the earthquake itself.
Answer:
176.58Watts
Explanation:
Power= work done /time
Where mass(m)=60kg
Height (h) =3m
Time(s)=10s
Force of gravity = 9.81m/s^2
Power=mgh/t
Power= (60kg) * (9.81m/s^2) * (3m)/10s
Power= 176.58Watts
I believe the instrument is called a Chordophone. It is an instrument that produces sound from a vibrating string stretched between two points, the string may be set in motion by bowing, striking, or plucking. It is one of the four major divisions of instruments in the original Hornbostel-Sachs scheme of musical instrument classification
Answer:
-14.2m/s
Explanation:
Given parameters:
Initial velocity of the ball = 25m/s
Time = 4s
Unknown:
Final velocity of the ball = ?
Solution:
To solve this problem, we use the expression below;
v = u - gt
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
t is the time
v = 25 - (9.8 x 4) = -14.2m/s
6. gas
7. liquid
8. gas
9. does not change
10. boiling point
