Since the connection is in series, the current divider can be used. It's mathematical expression is In = (It Rt) / Rn. If the value for is solved, power dissipation can also be solved using P = I^2 R.
I = 0.47 A
A. P = (0.47)^2 (5) = 1.11 Watts
B. P = (0.47)^2 (9) = 2 Watts
C. P = VI = 16(0.47) 4.24 Watts
Answer:
Savage is the answer
Explanation: The savage people guess like me
The speed with which the car going just before the driver slammed the brakes is 25.28 m / s, if the car skids to halt at a uniform rate of -9.4 m/s^2.
v² = u² + 2 a s
v = Final velocity
u = Initial velocity
a = Acceleration
s = Displacement
v = 0
a = - 9.4 m / s²
s = 34 m
0 = u² + ( 2 * - 9.4 * 34 )
u² = 639.2
u = 25.28 m / s
Deceleration is the slowing down of an object. It can be negative acceleration or positive acceleration. Deceleration is negative if the object moves in positive direction and it is positive if the object moves in negative direction.
Therefore, the speed with which the car going just before the driver slammed the brakes is 25.28 m / s

Answer:
Pressure amplitude, 
Explanation:
It is given that,
The maximum displacement equal to the diameter of an oxygen molecule, 
Speed of sound at 0 degrees is, v = 331.5 m/s
The pressure amplitude for the longitudinal wave is given by :
Where
is the density of air, 
f is the frequency say 59 Hz
So, pressure amplitude is given by :
So, the pressure amplitude in a sound wave in the air must be . Hence, this is the required solution.
