D = v^2 / 2ug
d= 3.5^2 / 0,15 x 9.8 m/s^2
the answer should be around 4.2m
hope this helps
Answer:
1.Length is one of the four factors on which the wave frequency depends. So if the length of the string changes then there will be a change in the vibration of string. So in this case if the lengths are different then the wave frequency of both will be different.
2. Wave speed will be the same as it depends on tension and linear density of it.
3. Wavelength itself is find out by the length of string so it depends on length and it will vary with the lengths of strings.
Explanation:
Answer:
The object takes approximately 1.180 seconds to complete one horizontal circle.
Explanation:
From statement we know that the object is experimenting an Uniform Circular Motion, in which acceleration (
), measured in meters per square second, is entirely centripetal and is expressed as:
(1)
Where:
- Period of rotation, measured in seconds.
- Radius of rotation, measured in meters.
If we know that 
and 
, then the time taken by the object to complete one revolution is:
The object takes approximately 1.180 seconds to complete one horizontal circle.
Answer:
The answer is below
Explanation:
The maximum height (h) of a projectile with an initial velocity of u, acceleration due to gravity g and at an angle θ with the horizontal is given as:
Given that the two projectile has the same height.
As we move from Radiowaves to UV waves in electromagnetic spectrum we know that the wavelength is maximum for radio waves while its frequency is minimum
PART (i)
So as we move from radiowaves to UV region
the Frequency will increase
Part (ii)
As we move from Radiowaves to UV region all the parts must have same speed in same medium
All parts will move with speed of light
so Speed will remain the same
