Lightbulb A is marked "25 W 120V, "and lightbulb B is marked "100 W 120V " These labels mean that each lightbulb has its respect

Dovator [93]

The cost of running the lightbulb A for 30 days at 0.110 per KWh is 1.98

<h3>How to determine the energy </h3>

We'll beging by calculating the energy used by lightbulb A. This can be obtained as follow:

Power (P) = 25 watts = 25 / 1000 = 0.025 KW
Time (t) = 30 days = 30 × 24 = 720 h
Energy (E) =?

E = Pt

E = 0.025 × 720

E = 18 KWh

<h3>How to determine the cost for running the bulb for 30 days</h3>

The cost of running the bulb for 30 days can be obtained as follow:

Cost per KWh = 0.11
Energy (E) = 18 KWh
Cost =?

Cost = energy × Cost per KWh

Cost = 18 × 0.11

Cost = 1.98

A 0.20-kg object is attached to the end of an ideal horizontal spring that has a spring constant of 120 N/m. The simple harmonic

miss Akunina [59]

Answer:

0.07756 m

Explanation:

Given mass of object =0.20 kg

spring constant = 120 n/m

maximum speed = 1.9 m/sec

We have to find the amplitude of the motion

We know that maximum speed of the object when it is in harmonic motion is given by $v_{max}=A\omega$ where A is amplitude and $\omega$ is angular velocity
