Frequency = (speed) / (wavelength)

Speed = 3 x 10⁸ m/s

Wavelength = 3 cm = 0.03 m

Frequency = (3 x 10⁸ m/s) / (0.03 m)

Frequency = (3 x 10⁸ / 0.03) (m / m-s)

Frequency = 1 x 10¹⁰ Hz (10 Gigahertz)

A small sphere is hung by a string from the ceiling of a van. When the van is stationary, the sphere hangs vertically. However,

olganol [36]

Answer with Explanation:

We are given that

String makes an angle w.r.t vertical= $\theta=$

a.We have to derive an expression for the magnitude of the acceleration of the van in terms of the angle $\theta$ and magnitude g of the acceleration due to gravity.

According to newton's second law

$T sin\theta=ma$

$Tcos\theta=mg$

$\frac{Tsin\theta}{Tcos\theta}=\frac{ma}{mg}$

$tan\theta=\frac{a}{g}$

$a=gtan\theta$

b. $\theta=10^{\circ}$

$g=9.8 m/s^2$

$a=9.8\times tan10^{\circ}=1.73 m/s^2$

c.Velocity=Constant

We have to find the angle $\theta$

$a=0$

$0=9.8tan\theta$

$tan\theta=0$

$tan\theta=tan0$

$\theta=0^{\circ}$

When the temperature of 2.35 m^3 of a liquid is increased by 48.5 degrees Celsius, it expands by 0.0920 m^3. What is its coeffic

alexandr1967 [171]

Coefficient of volume expansion is 8.1 ×10⁻⁴ C⁻¹.

<u>Explanation:</u>

The volume expansion of a liquid is given by ΔV,

ΔV = α V₀ ΔT

ΔT = change in temperature = 48.5° C

α = coefficient of volume expansion =?

V₀ = initial volume = 2.35 m³

We need to find α , by plugin the given values in the equation and by rearranging the equation as,

$\alpha=\frac{\Delta \mathrm{V}}{\mathrm{V}_{0} \Delta \mathrm{T}}=\frac{0.0920}{2.35 \times 48.5}=0.00081$

= 8.1 ×10⁻⁴ C⁻¹.

DesCribed briefly the method you would take in location the position of an object A defined by an ordered pair of value (8,4)

Strike441 [17]

Answer:

Explanation:

The method that I will use to locate the position of an object of ordered pair of value (8, 4) is known as the graphical method. The ordered pair of value (8, 4) is known as the coordinates. In graphical method, the coordinate will be located on the Cartesian plane having both x and y axis. The graph will be a 2-dimensional graph with y-axis being along the vertical and the x-axis along the horizontal.

The coordinates (8, 4) means that the value of x is +8 and the value of y is +4. To locate the point P(8, 4) on the graph, we will have to locate both points on the positive x and y axis respectively and then mark out their point of intersection. This point of intersection will be the position of the object defined as ordered pair of value (8,4).
