To calculate wind chill, enter the current ambient temperature in degrees Fahrenheit (°F) and enter the speed of the wind in miles per hour
<span>To produce a charge of 1.15 Coulombs in an object, we need to transfer = 1.15/(charge on an electron) number of electrons
As we know that, total charge on an electron = 1.60217662 Ă— 10 ^-19 coulombs
Hence, number of electrons required to move = 1.15/(1.60217662 Ă— 10 ^-19)
= 0.71777 x 10^19 electrons, i.e. 7.17 x 10^18 electrons upto 3 significant figures</span>
False
<u>Explanation:</u>
A positive magnification means the image is erect compared to the object. Magnifications with values greater than one represent images that are smaller than the object. A magnification of 1 (plus or minus) means that the image is the same size as the object. If m has a magnitude greater than 1 the image is larger than the object, and an m with a magnitude less than 1 means the image is smaller than the object. If the magnification is positive, the image is upright compared to the object; if m is negative, the image is inverted compared to the object.

_______________
h=7,5 m
g=10 m/s²
ρ=1000 kg/m³
_______________
p - ?
_______________
p=ρgh=1000 kg/m³ · 10 m/s² · 7,5 m = 75000 Pa = 75 kPa
