Answer:

Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.

Explanation:

The distance $y$ from the central band to the first bright band is given by

$y = \dfrac{ \lambda D}{d}$

where $\lambda$ is the wavelength of light (or any particle), $D$ is the distance to the screen, and $d$ is the slit separation.

From this equation we see that, by increasing the wavelength $\lambda$ , increasing the distance from the screen $D$ , and decreasing the slit separation $d$ , we increase the distance between the first bright band and the central band.

Therefore, the 2nd choice "<em>Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.</em>" is correct.

Answer:

Maximum Tension=224N

Minimum tension= 64N

Explanation:

Given

mass =8 kg

constant speed = 6m/s .

g=10m/s^2

Maximum Tension= [(mv^2/ r) + (mg)]

Minimum tension= [(mv^2/ r) - (mg)]

Then substitute the values,

Maximum Tension= [8 × 6^2)/2 +(8×9.8)] = 224N

Minimum tension= [8 × 6^2)/2 -(8×9.8)]

=64N

Hence, Minimum tension and maximum Tension are =64N and 2224N respectively

Answer:

Thermocouple, also called thermal junction, thermoelectric thermometer, or thermel, a temperature-measuring device consisting of two wires of different metals joined at each end. One junction is placed where the temperature is to be measured, and the other is kept at a constant lower temperature.

An object is thrown upward with a speed of 15 m/s on the surface of planet X where the acceleration due to gravity is 2.5 m/s2.

Alex

Answer:

12s

Explanation:

the formula is

s = u×t + 0.5×a×t²

where:

s is the displacement of the object at this time (so it's equal to 0)

u is the initial speed

t is the time you have to find

a is the acceleration due to gravity

$0 = 15 \frac{m}{s} \times t + 0.5 \times 2.5 \frac{m}{{s}^{2} } \times {t}^{2}$

$15 \frac{m}{s} \times t = 0.5 \times 2.5 \frac{m}{ {s}^{2} } \times {t}^{2}$

$15 \frac{m}{s} = 1.25 \frac{m}{{s}^{2} } \times {t}$

$t = \frac{15 \frac{m}{ {s}^{} } }{1.25 \frac{m}{ {s}^{2} } }$

$t = 12s$

Answer:

Sound energy wave is transferred through a substance as a series of compressions.

Explanation:

Sound is caused by regular oscillating that produce regions of compression (high pressure) and rarefaction (low pressure) that move through a substance. Sound not only travels through air, it can travel through any substance, solid, liquid or gas. Whales can hear other whales across whole oceans through water, an Earthquake is low frequency sound moving through the solid Earth

A vibrating object compresses the air and sound waves move from the source, much like waves in water if you drop a stone into it. These sound waves can carry great distances depending on their loudness and frequency.
