Answer:
Explanation:
distance of fan A = 18.3 m
distance of fan B = 127 m
speed of sound (s) = 343 m/s
What is the time difference between hearing the sound at the two locations?
time (T) = distance / speed
- time for sound to reach fan A = 18.3 / 343 = 0.053 s
- time it takes for sound to reach fan B = 127 / 343 = 0.370 s
- time difference = 0.370 - 0.053 = 0.317 s
Answer:
a = -1,33 m / s²
Explanation:
This problem is kinematic in one dimension, let's use the equations
v = v₀ + a t
v₀ = v - at
x = v₀ t + ½ a t²
we substitute the first in the second equation
x = (v-at) t + ½ a t²
x -v t = a t² (1 + ½)
a = (x -vt) / t² (1.5)
we calculate
a = (100 - 30 10) / 10² (1.5) =-200 / 150
a = -1,33 m / s²
Answer:
the interaction between the use of a charged object
Explanation:
honestly just had my certified physics educator dad tell me to write that lol sorry.
The answer yo this question is:
B-"Nitrogen, Arsenic, and Antimony"
Because its the only one out of all of the rest of the list that it contain properties that have similar element
Your Welcome :)
The Earth's gravitational pull and the table's force are of equal magnitude and in opposite directions, they balance each other.
<u>Explanation:</u>
A book placed on a surface have two forces acting on it which are, a force that pulls it toward the ground in a downward direction, that is gravitational pull and a second which is acted on the book on upward direction making a balance on the object.
This follows Newton’s third law of motion that states every action has an equal and opposite reaction.
