If an electrical component with a resistance of 53 Q is connected to a 128-V source, how much current flows through the componen
1 answer:
Answer:
the current that flows through the component is 2.42 A
Explanation:
Given;
resistance of the electrical component, r = 53 Ω
the voltage of the source, V = 128 V
The current that flows through the component is calculated using Ohm's Law as demonstrated below;
Therefore, the current that flows through the component is 2.42 A

B. A car of mass 2000 kg with speed 7 m/s
Explanation:
The kinetic energy of an object is given by:
where m is the mass of the object and v is its speed.
From the formula, we see that the larger the mass and the speed of the object, the larger its kinetic energy. Among the choices given, we see that the car with largest mass and largest speed is car B, which has a mass of 2000 kg and speed of 7 m/s. Its kinetic energy is:
We can verify that the other cars have smaller kinetic energy. In fact:
- Car A:
- Car C:
- Car D:
So, car B is the one which has most kinetic energy.

Answer:
Explanation:
From the question we are told
The amplitude of the lateral force is
The frequency is
The mass of the bridge per unit length is
The length of the central span is
The oscillation amplitude of the section considered at the time considered is
The time taken for the undriven oscillation to decay to of its original value is t = 6T
Generally the mass of the section considered is mathematically represented as
