Answer:

statement b is correct

Explanation:

In water the molecules are more close together and can vibrate faster (send sound waves) whereas in gas the molecules are more further away from each other and hence sound is slowest in gas and fastest in solids

Suppose the minimum uncertainty in the position of a
Anika [276]

Answer:

The minimum uncertainty in its speed is greater than 6.52\times 10^4\ m/s.

Explanation:

It is given that,

Speed of the particle, v=4.1\times 10^5\ m/s

We need to find the minimum uncertainty in its speed. It can be calculated using uncertainty principle as :

\Delta x.\Delta p\ge \dfrac{h}{2\pi}

Since, p = mv

\Delta x.\Delta (mv)\ge \dfrac{h}{2\pi}

(\dfrac{h}{mv}).(m\Delta v)\ge \dfrac{h}{2\pi}

\dfrac{\Delta v}{v}\ge \dfrac{h}{2\pi}

\Delta v\ge \dfrac{v}{2\pi}

\Delta v\ge \dfrac{4.1\times 10^5}{2\pi}

\Delta v\ge 6.52\times 10^4\ m/s

So, the minimum uncertainty in its speed is greater than 6.52\times 10^4\ m/s. Hence, this is the required solution.

a wave is represented by the equation y=0.5 sin0.6×(x-60t) where the distance x is measured in cm and time t is seconds. what is
Grace [21]

Answer:

lamda=10.5m

Explanation:

using the equation of progressive wave.

y=Asin(wt-kx)

comparing the two equations together, we have

kx=0.6x , k=0.6

k=2π/λ

0.6=2*3.142/λ

cross multiply

0.6λ=6.284

divide both sides by 0.6

λ=6.284/0.6

λ=10.47m

approximate

λ=10.5m

Good Afternoon my son has a science project the category is Physical science can you'll give me science Ideas he can do I'm New
Naddik [55]

As a experiment you could use is The affect of light in plants. A study He can do is maybe about Gravity affects and how it works on weight. Also you can do a all time favorite the Mentos and Diet Coke Experiment.

Hopefully one of these ideas will inspire you!
