Answer:
The value of tangential acceleration  40
  40 
The value of radial acceleration 
Explanation:
Angular acceleration = 50 
Radius of the disk = 0.8 m
Angular velocity = 10 
We know that tangential acceleration is given by the formula  
 
Where r =  radius of the disk
 = angular acceleration
 = angular acceleration 
⇒  0.8 × 50
 0.8 × 50 
⇒  40
 40 
This is the value of tangential acceleration.
Radial acceleration is given by 

Where V = velocity of the disk = r 
⇒ V = 0.8 × 10
⇒ V = 8 
Radial acceleration 


This is the value of radial acceleration.
 
        
             
        
        
        
Answer:
The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.

Answer:
 = 1.7 cm
 = 1.7 cm
Explanation:
The magnification of the compound microscope is given by the product of the magnification of each lens
         M = M₀  
         M = - L/f₀  25/
Where f₀ and  are the focal lengths of the lens and eyepiece, respectively, all values in centimeters
 are the focal lengths of the lens and eyepiece, respectively, all values in centimeters
In this exercise they give us the magnification (M = 400X), the focal length of the lens (f₀ = 0.6 cm), the distance of the tube (L = 16 cm), let's look for the focal length of the eyepiece ( )
)
           = - L / f₀ 25 / M
 = - L / f₀ 25 / M
Let's calculate
          = - 16 / 0.6 25 / (-400)
 = - 16 / 0.6 25 / (-400)
          = 1.67 cm
 = 1.67 cm
The minus sign in the magnification is because the image is inverted.
            = 1.7 cm
 = 1.7 cm

Explanation:
To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows: If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2. If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375.
