Below is the solution:
<span>centripetal accel = 1.5*g
ω²r = 1.5*9.8m/s²
ω² * 8m = 14.7 m/s²
ω = 1.36 rad/s * 1rev/2πrads * 60s/min = 12.9 rpm</span>
Answer:
Minimum DC current 
Ampere
Voltage 
V
Explanation:
Here in this questions three resistors are used in series
Resistance of cap circuit
Here 
is the resistance per cap
Resistance of bus wire
Where 
is the resistance per 
feet of bus wire of gauge 16
Resistance of firing line
where 
is the resistance per feet of bus wire of gauge 14
Total resistance is equal to
Current in firing line is equal to
Voltage is equal to product of resistance and current
Answer:
B. 4.5N
Explanation:
F = kx
Where
F = force
K = spring constant
x = compression
Given
K = 15N/m
x = 0.3m
Therefore
F = 15 x 0.3
F = 4.5N
The magnitude of the force that resists the stretching is 4.5N
The trombone is a wind musical instrument and as all musical instruments can produce a standing (or stationary) wave.
This kind of waves is the result of the composition of two waves that produces a pattern that looks like it is not moving but just vibrating. Some points of the wave look like they are not even vibrating, they just stand still, and they are called nodes. Other points of the wave vibrate from the maximum positive value to the maximum negative value and are called antinodes.
