Answer:
tsunamis,El Nino,and volcanic eruptions
Explanation:
all short term.
P = m x g
P = Weight force = 55.54 N
M = Mass = ? kg
G = Gravity = 9.83 m/s^2
-> 55.54 = m x 9.83
-> m = 55.54/9.83
-> m = approximately 5.65 kg
Answer: The mass of the object is approximately 5.65 kg.
Answer:
a) t = 0.75 s, b) t = 2.25 s
Explanation:
The speed of sound is constant in a material medium
v = 340 m / s
we can use the relations of uniform motion to find the time
v = x / t
t = x / v
In the exercise, the observer's distance to the wall is indicated d = 510 m, it also indicates that the shot is fired at the midpoint
x = d / 2
a) direct sound the distance from the observer to the screen is
x = 510/2 = 255 m
t = 255/340
t = 0.75 s
b) echo sound.
In this case the sound reaches the wall bounces, the distance is
x = d / 2 + d
x = 3/2 d
x = 3/2 510
x = 765 m
the time is
t = x / v
t = 765/340
t = 2.25 s
Answer:
Nucleus is not a subatomic particle.
Explanation:
Protons and Neutrons in the nucleus make up most of the mass of an atom, and electrons orbit outside of the nucleus.
