Answer:
oh umm it think its TV=11x*20s
Explanation:
This information describes the storm's velocity.
They are the same. If this is all happening on Earth, then the ball's acceleration is 9.8 m/s^2 in either case. That's the acceleration of gravity around here.
Answer:
L = 44,096 m
Explanation:
The speed of the sound wave is constant therefore we can use the relations of uniform kinematics
v = x / t
the speed of the wave in the bar is
v = 15 v or
v = 15 343
v = 5145 m / s
The sound at the bar goes the distance
L = v t
Sound in the air travels the same distance
L = v_air (t + 0.12)
as the two recognize the same dissonance,
v t = v_air (t +0.12)
t (v- v_air) = 0.12 v_air
t = 0.12 v_air / (v -v_air)
l
et's calculate
t = 0.12 343 / (5145 - 343)
t = 8.57 10-3 s
The length of the bar is
L = 5145 8.57 10-3
L = 44,096 m
Answer:
58.5 deg
Explanation:
= mass of the pig toy = 0.30 kg
= speed of the toy = 2 m/s
= radius of the circle = 0.25 m
= Angle of the string with the vertical = ?
= Tension force in the string
Using equilibrium of force in vertical direction
eq-1
Along the horizontal direction, the component of tension force provides the necessary centripetal force, hence
eq-2
Dividing eq-2 by eq-1
= 58.5 deg
