Answer:
The time interval is 
Explanation:
From the question we are told that
The angular acceleration is 
The time taken is 
The angular displacement is 
The angular displacement can be represented by the second equation of motion as shown below

where
is the initial velocity at the start of the 4 second interval
So substituting values

=> 
Now considering this motion starting from the start point (that is rest ) we have

Where
is the angular velocity at rest which is zero and
is the angular velocity after 4.0 second which is calculated as 12 rad/s s

=> 
Answer:
485520 m
Explanation:
= initial velocity of the projectile = 1360 m/s
= final velocity of the projectile =
=
= 544 m/s
a = acceleraton due to gravity on moon = - 1.6 m/s²
h = Altitude of the projectile
Using the kinematics equation

Inserting the values

h = 485520 m
Answer:It's how the color mixes together . Red and green both makes a dark color
Explanation:
72 m/s
Explanation:
Given,
Frequency ( f ) = 6 Hz
Wavelength ( λ ) = 12 m
To find : -
Speed ( v ) = ?
Formula : -
v = f x λ
v
= 6 x 12
= 72 m/s
Therefore,
the speed of a wave with a frequency of 6 Hz and a wavelength of 12 m is 72 m/s.
