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

Answer:
yes i do becuase humans are here but by being here they disrupt the structure of plants and animals.
Explanation:
Answer:
Explanation:
given,
Speed of a wave on violin A = 288 m/s
Speed on the G string = 128 m/s
Force at the end of string G = 110 N
Force at the end of string A = 350 N
the ratio of mass per unit length of the strings (A/G). = ?
speed for string A
.......(1)
speed for string G
........(2)
Assuming force is same in both the string
now,
dividing equation (2)/(1)
Answer:
Explanation:
Given,
mass of the object,m = 0.30 Kg
initial speed, v_i = 3 m/s
time of collision = 0.20 s
final speed, v_f = -4 m/s
Impulse = change in momentum
Hence, impulse of the object is equal to
This is a Rift Valley.
