I believe that <span>When you add something like </span>salt<span> to a solvent like </span>water<span>, it makes </span>water<span> become an impure solvent and raises its </span>boiling<span> point above that of pure solvents. Though </span>salt raises<span> the </span>boiling<span> point of </span>water<span>, it doesn't do it very much.</span>

Ratling [72]

Answer:

6.97 E 16

Explanation:

Frequency is a function of velocity of light to it's wavelength.

Mathematically written as

F = Velocity / wavelength

Velocity of light = 3 x 10^8

Wavelength =430 nm =430 x 10^-9 m

converting wavelength from nanaometer to meter we divide by 10^9

Frequency = (3 x 10^8)/(430 x10^-9) =6.97 E 16

36 The height of a 30-story building is approximately
ohaa [14]
An approximation used to measure building height is 10 feet per building level.

Converting from feet to meters using the equation:
1 ft = 0.3048m
10 ft = 3.048m

Multiplying that by 30 storeys, we get:
3 x 3.048m = 91.44m, which is near the answer of (3) 10^2 m or 100m.

34kurt

Answer:

The average current density at the position of the area.

Explanation:

Current density is the vector whose magnitude is electric current in the cross sectional area. Current density is vector quantity which is measured in amperes. The average current density is dependent on the electric current flow. It has perpendicular direction of flow and scalar magnitude.

If half of the weight of a flatbed truck is supported by its two drive wheels, what is the maximum acceleration it can achieve o
Scilla [17]

Answer:

Maximum acceleration will be equal to 3.43m/sec^2

Explanation:

We have given coefficient of kinetic friction \mu _k=0.7

And coefficient of static friction \mu _s=1

Acceleration due to gravity g=9.8m/sec^2

When truck moves maximum force will be equal to F=\mu _kmg

It is given that half of the weight is supported by its drive wheels

So force required =\frac{\mu _kmg}{2}

From newtons law maximum acceleration will be equal to a=\frac{\frac{\mu _kmg}{2}}{m}=\frac{\mu _kg}{2}=\frac{0.7\times 9.8}{2}=3.43m/sec^2
