Complete Question
Alberta is going to have dinner at her grandmother's house, but she is running a bit behind schedule. As she gets onto the highway, she knows that she must exit the highway within 55 min if she is not going to arrive late. Her exit is 43 mi away. How much time would it take at the posted 60 mph speed?
Answer:
The time it would take at the given speed is
Explanation:
From the question we are told that
The time taken to exist the highway is
The distance to the exist is
Alberta speed is
The time it would take travelling at the given speed is mathematically represented as
substituting values
Converting to minutes
1 hour = 60 minutes
So 0.71667 hours = x minutes
Therefore
Gamma waves have a short wavelength. The closer the wavelength () the higher frequency the wave is
Answer:
The system is still balanced
Explanation:
If we suppose that the boy weights M and the girl m, and are balanced at distances L1 and L2 from the pivot point respectively, thy will be balanced if the resultant torque of all the farces from the pivot pint is cero:
(1)
now they moved to distances (L1)/2 and (L2)/2, the resultant torque will be:
(2)
1/2 can be taken out as a common factor:
(3)
As the the inside of the parenthesis equals equation (1) that equals zero, hte whole equiation equals zero:
(3)
So the system is still balanced
