Answer:
Explanation:
Ah is a unit of charge .
A battery with 12 V and charge capacity of 40 Ah will have energy content
= volt x charge
volt = 12 V
Charge = 40 Ah
= 40 x 60 x 60 A.s
= 144000 coulomb
energy content = 12 x 144000
= 1728000 J
energy content of heavy duty battery
= 12 x 60 x 60 x 60
= 2592000 J
Ratio = 1728000 / 2592000
= 2 / 3
Current can not be compared as current depends upon the resistance of appliance used . As resistance of appliance is unknown , current can not be compared.
A pressure antinode in a sound wave is not a region of high pressure, while a pressure node is not a region of low pressure.
The answer is false
Answer:
I = 21.94 A
Explanation:
Given that
B= 0.15 T
Number of turns N= 3100
Length L = 57 cm
Diameter ,d= 7 cm
We know that magnetic field in the solenoid given as
Now by putting the values
I = 21.94 A
Therefore current need to produce 0.15 T magnetic filed is 21.94 A.
Answer:
An object in either state of equilibrium must have no net force acting on it.
Explanation:
The most probably answer among the presented options would be the one that says "road map is to passenger".
Let us establish first that we do not know what a thesis statement means and that we are just taking the statement as it is without any prior knowledge to the hard word present. The key to this would be the statement "it lets her know where the writer will take her." Among the ones presented as options, only the road map fits the description. Thus, the answer being road map is to passenger. The car is subject to the driver's commands thus the driver is the one guiding the car, and the student follows what is written in the study guide.
