In my opinion, i think the first one is the best one since we're cutting down on paper wasted in mails when its better to do it online.

"paying bills online instead of sending paper through mail"

A radioactive particle has a half life of 1 second. If it moves at 3/5 the speed of light, from my point of view standing still
AVprozaik [17]

The half-life observed by an observer at rest is 1.25 s

Explanation:

In this problem, the particle is travelling at a significant fraction of the speed of light: therefore, we have to consider the phenomenon of the time dilation. The half-life of the particle as measured by an observer at rest is given by

T=\frac{T_0}{\sqrt{1-(\frac{v}{c})^2}}

where

T_0 is the proper half-life of the particle

v is the speed of the particle

c is the speed of light

For the particle in this problem,

T_0 = 1 s

v=\frac{3}{5}c=0.6 c

Substituting into the equation, we find:

T=\frac{1}{\sqrt{1-(\frac{0.6c}{c})^2}}=1.25 s

Consider the numbers 23.68 and 4.12. The sum of these numbers has ____ significant figures, and the product of these numbers has
damaskus [11]

Answer:multiplying will give us 7 significant figures and addition will give us 3 significant figures

Explanation:

After multiplying the two numbers they resulting value will give a value in its 4 decimal places because both given values are in 2 decimal places. The 4 dp is gotten by the addition of the decimal places of both given numbers (2+2) and

The result of its addition will give us a value in its 1dp and 3 significant figures since the addition of 23.68 and 4.12 will give us 27.8

On a winter day with a temperature of -10°C, 500g of snow (water ice) is brought inside where the temperature is 18 °C. The snow
Serjik [45]

Answer:

Explanation:

Mass of ice m = 500g = .5 kg

Heat required to raise the temperature of ice by 10 degree

= mass of ice x specific heat of ice x change in temperature

= .5 x 2093 x 10 J

10465 J

Heat required to melt the ice

= mass of ice x latent heat

0.5 x 334 x 10³ J

167000 J

Heat required to raise its temperature to 18 degree

= mass x specific heat of water x rise in temperature

= .5 x 4182 x 18

=37638 J

Total heat

=10465 +167000+ 37638

=215103 J

If a wave traveling through air decreases its wavelength by half, describe what happens to the wave speed and frequency.
natka813 [3]
The frequency, the speed and the wavelength of a wave are related by the following equation:
f= \frac{v}{\lambda} (1)
where
f is the frequency
\lambda is the wavelength
v is the wave speed

The speed of the wave does depend only on the properties of the medium, so since the wave is still traveling in air, the medium has not changed and therefore the speed remains the same. We see instead from eq.(1) that the frequency is inversely proportional to the wavelength, so if the wavelength is decreased by half, we see that the frequency will double.
