Answer:
no
Explanation:
it is not healthy because sodium is not good to our body
Assuming that the magnitude is additive, then you simply have to add the brightness four times. This is because each star has 2 magnitudes of 8.34. As a result, you have to add 4 magnitudes of 8.34. The solution is as follows:
Magnitude = 4(8.34)
Magnitude = 33.36
Answer:
v = 7.9 m/s
Explanation:
length of the vine (L) = 20 m
initial angle with the vertical = 45 degrees
final angle with the vertical = 30 degrees
acceleration due to gravity (g) = 9.8 m/s^{2}
speed (v) =?
to solve this problem we can apply the equation below:
loss in potential energy = gain in kinetic energy
m x g x h = 1/2 x m x
v =
before we can apply the above we need to get our height
height = initial vertical height - final vertical height
height = (L - L cosθ2) - (L - L cosθ1)
height = (20 - 20cos45) - (20 - 20cos30) = 3.2 m
v =
v = 7.9 m/s
