Answer:
Torque, 
Explanation:
It is given that,
Length of the wrench, l = 0.5 m
Force acting on the wrench, F = 80 N
The force is acting upward at an angle of 60.0° with respect to a line from the bolt through the end of the wrench. We need to find the torque is applied to the nut. We know that torque acting on an object is equal to the cross product of force and distance. It is given by :
So, the torque is applied to the nut is 34.6 N.m. Hence, this is the required solution.
Answer:
Decrease of snake, coyote, and hawk population. Increase of sagebrush and cacti.
Reasons:
The rats are aten by the snake coyote and hawks so if a food source is taken from them they are going to have to fight more for food. The rats eat the sagebrush and cacti so if they arent getting eaten as much, they have mroe ime to produce.
Answer:
velocity and wavelength
Explanation:
When a ray of light moves from one medium to another, the ray of light changes the direction when it enters the second medium, refraction of light occurs.
When it changes the direction, the frequency will remain the same because it depends only on the source not on the medium.
As the refractive index of two medium is not same, it means the wavelength will change.
Also, speed = frequency × wavelength
So, wavelength and velocity changes. Hence, the correct option is (a).
Answer:
21 Hz, 43 Hz and 22 Hz
Explanation:
The computation of the beat frequencies that are generated by this discordant combination is as follows:
As we know that
beat frequencies = |f_1 - f_2|
So
For the first one
= |349 Hz - 370 Hz|
= 21 Hz
For the second one
= |349 Hz - 392 Hz|
= 43 Hz
And, for the third one
= |370 Hz - 392 Hz|
= 22 Hz
