Protons are positive, electrons are negative, and neutrons are neutral. In the nucleus, there are protons and neutrons, so the charge of a nucleus is positive
Answer:
Speed=28.1m/s(to 3s.f.) , Time=2.19s(to 3s.f.)
Explanation:
Time=Distance/Speed
=14.5/6.63
=2.19s(to 3s.f.)
Acceleration=Final Velocity(v)-Initial Velocity(u)/Time
9.81=v-6.63/2.19
v-6.63=21.5
v=28.1m/s
Answer
given,
Length of pipe, L = 2.65 m
speed of sound, v = 343 m/s
Pipe is open end Pipe
a) Lowest frequency
condition, for open end pipe
For lowest frequency
n = 1
f₁ = 64.72 Hz
b) For second frequency in bugle
n = 2
f₂ = 129.43 Hz
for n = 3
f₃ = 194.16 Hz
Answer; the free encyclopedia. In mechanics and physics, simple harmonic motion is a special type of periodic motion or oscillation where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.
Explanation:
If you're looking for the word it's heliocentric but if you're wondering what it is it's just where the sun is the center of the solar system and the planets all revolve around it.
