Answer:
The force needed will be greater to hold the object at rest.
Explanation:
For a better understanding let's take a look at the attached image.
In the image there is an example of this condition, we have an object of 3 kg-f mass, the first angle between the horizontal and the inclined plane is 35°. When we increase the angle to 45°. We can realize that we need to hold the object with a stronger force.
The calculation and the equations based on Newton's laws can be found in the attached image.
Answer:
wavelength of the sound wave will be 0.977 m
Explanation:
We have given frequency of the sound wave f = 351 Hz
Speed of the sound wave v = 343 m/sec
We have to find the wavelength of the sound wave
We know that velocity of the sound wave is given by
So wavelength of the sound wave
So wavelength of the sound wave will be 0.977 m
