1.2 percent of 155 million is 1,860,000. Divide that by 12 (for twelve months of the year) and get 155,000. That's the answer. 155,000.
Chemical energy is the answer to the energy stored in he bonds that hold together the atoms and molecules of all substances. SO answer C is the right one.
Hope this answers your doubt !! :)
The statements true concerning the strips with a positive versus a negative hall voltage are a and d.
<h3>
What is hall voltage?</h3>
The hall voltage is the potential created across a current-carrying metal-strip when the strip is placed in a magnetic field perpendicular to the current flow in the strip. it is used as a research tool to probe the movement of charges in materials, as well as determining the blood flow rate.
The top strip possess positive charge carriers, and the electric field points are in the same direction as the electric force.
The bottom strip has negative charge carriers, and the magnetic force points upward along the plate.
This will create an equilibrium of the magnetic force and electrostatic force.
Thus, the correct option are a and d.

Answer:
time required to mow lawn is 1274.06 minutes
Explanation:
given data
average mow = 1400 square meters each hour
area = 320000 square feet
to find out
How many minutes will take to mow lawn
solution
we know that here 1 square feet is equal to 0.092903 square meter
so 320000 square feet will be = 0.09203 × 320000 = 29728.9728 square meter
so time required is express as
time required =
time required =
time required = 21.23 hours
so time required = 21.23 × 60 min = 1274.06
time required to mow lawn is 1274.06 minutes
Answer:
Solar cell generates DC
Windmill generates AC
Explanation:
Solar cell generates DC from the panel, to use this DC for electricity it has to be passed to an inverter which convert DC to AC.
Windmill generates AC from the wind blades. This type of energy can be used directly with household appliances using AC, or passed to a rectifier to convert it to DC.
