Uhm, if this is a problem on a piece of paper or anything then I would recommend to take a picture of it, instead of writing it all out.

Answer:

Regulatory

Step-by-step explanation:

the rectangular sign with longer vertical dimension and have white background  are called regulatory signs.

regulatory signs are those signals which are used to indicate or reinforce traffic laws.

these regulatory sign informs the driver and tell them to apply the traffic law at certain required places.

An adult brain is about 140 mm wide and divided into two sections (called "hemispheres" although the brain is not truly spherica
Sedbober [7]

Answer: 3.61×10^5 A

Step-by-step explanation: Since the brain has been modeled as a current carrying loop, we use the formulae for the magnetic field on a current carrying loop to get the current on the hemisphere of the brain.

The formulae is given below as

B = u×Ia²/2(x²+a²)^3/2

Where B = strength of magnetic field on the axis of a circular loop = 4.15T

u = permeability of free space = 1.256×10^-6 mkg/s²A²

I = current on loop =?

a = radius of loop.

Radius of loop is gotten as shown... Radius = diameter /2, but diameter = 65mm hence radius = 32.5mm = 32.5×10^-3 m = 3.25×10^-2m

x = distance of the sensor away from center of loop = 2.10 cm = 0.021m

By substituting the parameters into the formulae, we have that

4.15 = 1.256×10^-6 × I × (3.25×10^-2)²/2{(0.021²) + (3.25×10^-2)²}^3/2

4.15 = 13.2665 × 10^-10 × I/ 2( 0.00149725)^3/2

4.15 = 1.32665 ×10^-9 × I / 2( 0.000058)

4.15 × 2( 0.000058) = 1.32665 ×10^-9 × I

I = 4.15 × 2( 0.000058)/ 1.32665 ×10^-9

I = 4.80×10^-4 / 1.32665 ×10^-9

I = 3.61×10^5 A

Help for 1,2,3,4 please
ikadub [295]

In every case, you're finding the surface area of a rectangular prism. That area is the sum of the areas of the 6 rectangular faces. Since opposite faces have the same area, the formula can be written

... S = 2(LW +WH +HL)

The number of multiplications can be reduced if you rearrange the formula to

... S = 2(LW +H(L +W))

where L, W, and H are the length, width, and height of the prism. (It does not matter which dimension gets what name, as long as you use the same number for the same variable in the formula.)

When you're evaluating this formula over and over for diffferent sets of numbers, it is convenient to let a calculator or spreadsheet program do it for you.

1. S = 2((5 cm)(5 cm) +(5 cm)(5 cm +5 cm)) = 2(25 cm² +(5 cm)(10 cm))

... = 2(25 cm² + 50 cm²) = 150 cm²

2. S = 2(12·6 + 2(12+6)) mm² = 2(72 +36) mm² = 216 mm²

3. S = 2(11·6 + 4(11 +6)) ft² = 2·134 ft² = 264 ft²

4. S = 2(10·4 +3(10 +4)) in² = 164 in²
