Answer:
Shows directions accurately
Explanation:
Even though the countries are distorted, they still show the correct coordinates. Sailors use this specifically for that reason. All of the maps are used differently, Conic maps are for better use of road trips or travelling
Hoped this helped
Answer:
It is given that power = 5000 W for 120 V and resistance is per 1000 ft of wire. The wire is 750 ft away from 120 V source. We need find the voltage delivered to this load.
Resistance of 750 ft wire, =
Using Ohm's Law:
Voltage delivered to the load,
Answer:
(a) v = 32 t
h = 16 t^2
g = 32 ft/s^2
(b) 64 ft/s
Explanation:
height, h = 64 feet
g = - 32 ft/s^2
(a) Let the time is t .
Let the velocity after time t is v.
Use first equation of motion
v = u + at
- v = 0 - 32 t
v = 32 t
Let the distance is h from the top.
Use second equation of motion
The acceleration is constant for entire motion.
(b) Let the velocity is v as it hits the ground. Use third equation of motion
Answer:
The value of g is
Explanation:
From the question we are told that
The mass of the weight is
The spring constant
The second harmonic frequency is
The number of oscillation is
The time taken is
Generally the frequency is mathematically represented as
At second harmonic frequency the length of the string vibrating is equal to the wavelength of the wave generated
Noe from the question the vibrating string is just half of the length of the main string so
Let assume the length of the main string is
So
The velocity of the vibrating string is mathematically represented as
Where T is the tension on the string which can be mathematically represented as
So
Then
=>
=>
=>
substituting values
Generally the period of oscillation is mathematically represented as
=>
The period can be mathematically evaluated as
substituting values
Therefore
so
substituting for L
=>
