m_a_m_a [10]

Answer:

$10^{-35}\ meters$

Explanation:

The string theory is a theoretical concept, the very small particles of particle physics are rep[laced by strings. This theory also applies to black hole physics, nuclear physics, cosmology etc.

According to string theory, six space-time dimensions cannot be measured except as quantum numbers of internal particle properties because they are curled up in size of the order of $10^{-35}\ m$ .

The length of the scale is assumed to be on the order of $10^{-35}\ m$ . Hence, the correct option is (a).

Attempting to impress the skeptical patrol officer with your physics knowledge, you claim that you were traveling so fast that t

horsena [70]

Answer:

v_r = 1.268 × 10⁸ mi/hr

Explanation:

We are given;

wavelength of the red light; λr = 693 nm = 693 × 10^(-9) m

wavelength of the yellow light; λy = 582 nm = 582 × 10^(-9) m

Frequency is given by the formula;

f = v/λ

Where v is speed of light = 3 x 10^(8) m

Frequency of red light; f_o = [3 x 10^(8)]/(693 × 10^(-9)) = 4.33 x 10¹⁴ Hz

Similarly, Frequency of yellow light;

f = [3 x 10⁸]/(582 × 10^(-9)) = 5.15 x 10¹⁴ Hz

To find the speed of the car, we will use the formula;

f = f_o[(c + v_r)/c)]

Where c is speed of light and v_r is speed of car.

Making v_r the subject;

cf/f_o = c + v_r

v_r = c(f/f_o - 1)

So, plugging in the relevant values, we have;

v_r = 3 × 10⁸[((5.15 x 10¹⁴)/(4.33 x 10¹⁴)) - 1]

v_r = 3 × 10⁸(0.189)

v_r = 5.67 x 10⁷ m/s

Converting to mi/hr, 1 m/s = 2.23694 mile/hr

So, v_r = 5.67 × 10⁷ × 2.23694

v_r = 1.268 × 10⁸ mi/hr

The density of a material is calculated by:

anyanavicka [17]

Answer:

The density of the material is defined as the mass of the material to its volume.

ρ = M / V

Explanation:

The density of the material is a scalar quantity.

If the mass and the volume of the material is known the density of the material can be calculated using the formula,

ρ = M / V

The mass of the material can be found using a physical balance.

The volume of a geometrically symmetrical material can be found using the geometrical measurement. For a brick,

V = l x b x h

For non-geometrically shaped material the volume can be found from the displacement method using water.
