This is a riddle meant to have a humorous effect.
So, what did they call the bug that the astronauts brought back from the moon? - A lunatic.
The word lunatic consists of lunar (relating to the Moon) and tick, which is a type of an insect.
The solution to the problem is as follows:
Normal force is m*g plus 240 N*sin30.
<span>30 kg*9.8 m/s^2 + 240 N*sin30 = 414 N

Answer:
8
Explanation:
Applying,
v = λf................ Equation 1
Where v = velocity/ speed of the wave, λ = wave length of the wave, f = number of waves the person surf in one seconds.
make f the subject of the equation
f = v/λ............ Equation 2
From the question,
Given: v = 1.6 m/s, λ = 24 m
Substitute these values into equation 2
f = 1.6/24
f = 0.0667 wave/seconds.
If,
in one seconds, the person surf a total wave crest of 0.0667
Therefore,
in one hours, he will surf a total wave crest of (0.0667×60×60) = 240 waves crest
He rides for every 30th wave crest,
Hence,
number of wave crest the person surf in one hour = 240/30 = 8
Answer:
D
Explanation:
From the information given:
The angular speed for the block 
Disk radius (r) = 0.2 m
The block Initial velocity is:
Change in the block's angular speed is:
However, on the disk, moment of inertIa is:
The time t = 10s
∴
Frictional torques by the wall on the disk is:
Finally, the frictional force is calculated as:
The rocket engine works on the basic principle proposed by Newton which is Newton’s Third Law.
