What is the number of waves that pass a fixed ping in a given amount of time?
Viktor [21]
The number of waves that pass a fixed point in a given amount of time is wave frequency. Wave frequency can be measured by counting the number of crests (high points) of waves that pass the fixed point in 1 second or some other time period. The higher the number is, the greater the frequency of the waves. :)

You are driving at 25 m/s with your cruise control on when you see a fallen tree in the road. It takes you 0.30 s to put on the
xxTIMURxx [149]

Explanation:

Given data

velocity v= 25m/s

The time it takes to put on brake t= 0.3s

the distance covered when the  brake was put on is

v=s/t

s= v*t

s= 25*0.3s

s= 7.5m

hence the distance covered is 7.5m

Also the rate of decrease in aceleration is 5m/s^2

we can also calculate the distance covered at this rate

v^2=u^2+2as

25^2= 0+2*5*s

625=10s

divide both sides by 10

s=625/10

s= 62.5m

The total  distance covered between putting on the brakes and decelareation is  7.5+62.5= 70m

Given that the tree is 75m ahead, the car would not hit the tree

The atomic radii of a divalent cation and a monovalent anion are 0.19 nm and 0.126 nm, respectively. (a) Calculate the force of
Alchen [17]

Explanation:

Given that,

Radius of divalent cation, a_1=0.19\ nm

Radius of monovalent anion, a_2=0.126\ nm

Charge for divalent cation, Z_1=+2

Charge for monovalent cation, Z_2=-1

The sum of radii of both cations and anion is, a_o=0.19+0.126=0.316\ nm=0.316\times 10^{-9}\ m

(a) The force of attraction between two ions is given by :

F=k\dfrac{-Z_1Z_2e^2}{a_o^2}

F=-9\times 10^9\times \dfrac{2\times (-1)\times (1.6\times 10^{-19})^2}{(0.316\times 10^{-9})^2}

F=4.61\times 10^{-9}\ N

(b) Let F' is the force of repulsion at this same distance such that,

F + F' = 0

So, F'=-4.61\times 10^{-9}\ N

Hence, this is the required solution.
