Answer:
The largest voltage is 0.02 V.
(d) is correct option.
Explanation:
Given that,
Range = 20 dB
Smallest voltage = 200 mV
We need to calculate the largest voltage
Using formula of voltage gain
Hence, The largest voltage is 0.02 V.

The mass is missing. The mass of the elevator is 1650 kg.
Answer:
The tension in the cable is 19387.5 N.
Explanation:
Given:
Initial velocity of the elevator (u) = 0 m/s
Acceleration in the upward direction (a) = 1.95 m/s²
Time taken by the elevator (t) = 2.15 s
Mass of the elevator and persons (m) = 1650 kg
Let the tension in the cable wire be 'T' Newtons.
Now, there are 2 forces acting in the vertical direction. One is tension in the upward direction and the other the weight of the elevator in the downward direction.
As the elevator is accelerating upward, the net force acts in the upward direction.
So, net force on the elevator is given as:
Now, from Newton's second law, net force equals mass times acceleration.
Plug in the given values and solve for 'T'. This gives,
Therefore, the tension in the cable is 19387.5 N.
Answer:
La fuerza que realiza el motor es 2035 N.
Explanation:
Podemos encontrar la fuerza del motor usando la siguiente ecuación:
(1)
En donde:
m: es la masa del coche = 550 kg
a: es la aceleración
Se puede calcular la aceleración mediante la siguiente ecuación cinemática:
(2)
En donde:
: es la velocidad final del coche = 100 km/h
: es la velocidad inicial del coche = 0
t: es el tiempo = 7,5 s
Resolviendo la ecuación (2) para "a" tenemos:
Entonces, la fuerza es:
Por lo tanto, la fuerza que realiza el motor es 2035 N.

Answer:
D.) A carpet transfers more energy to heat than the floor.
The frictional force between carpet and ball is more due to the rough surface of the carpet as compared to the friction between floor and ball, so the ball on the carpet would come to rest first before a ball on the floor.
