Answer:
Resistor
Explanation:
Resistor provides resistance to the flow of electric current in a circuit. 
It controls the amount of current in a circuit by acting as a barrier to the flow of electric charges 
 
        
                    
             
        
        
        
Displacement is the final position of the object minus the initial position of the object. 
Xf - Xi. Displacement is not the distance of the object. If you go to the right 10m and to the left another 10m, your displacement is 0m. But your distance is 20m
        
             
        
        
        
Pressure is defined as the force per unit area on a body.
        
                    
             
        
        
        
To solve this problem we will apply the concepts related to the Doppler effect. According to this concept, it is understood as the increase or decrease of the frequency of a sound wave when the source that produces it and the person who captures it move away from each other or approach each other. Mathematically this can be described as

Here,
 = Original frequency
 = Original frequency
 = Velocity of the observer
 = Velocity of the observer
 = Velocity of the speed
 = Velocity of the speed 
Our values are,



Using the previous equation,

Rearrange to find the velocity of the observer

Replacing we have that


Therefore the velocity of the observer is 16.2m/s
 
        
             
        
        
        
Answer:
33,02 lb
Explanation:
g_m ≈ 1,62 m/s2
g ≈ 9,81 m/s2
m = 200 lb
m_m = m * g_m / m = 200 * 1,62 / 9,81 = 33,02 lb
