Answer:
The angle is 
Explanation:
From the question we are told that
The distance of separation is 
The wavelength of light is 
Generally the condition for destructive interference is mathematically represented as
![dsin(\theta ) =[m + \frac{1}{2} ]\lambda](https://tex.z-dn.net/?f=dsin%28%5Ctheta%20%29%20%20%3D%5Bm%20%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20%5D%5Clambda)
Here m is the order of maxima, first minimum (dark space) m = 0
So
![100 *10^{-6 } * sin(\theta ) =[0 + \frac{1}{2} ]600 *10^{-9}](https://tex.z-dn.net/?f=100%20%2A10%5E%7B-6%20%7D%20%2A%20%20sin%28%5Ctheta%20%29%20%20%3D%5B0%20%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20%5D600%20%2A10%5E%7B-9%7D)
=> ![\theta = sin^{-1} [0.003]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20%20sin%5E%7B-1%7D%20%5B0.003%5D)
=> 
Answer:
40.13491 m/s
Explanation:
= My speed = 35 m/s
v = Speed of sound in air = 343 Hz
= Speed of the police car
When the car is approaching

When the car is receding

Dividing the equations

The speed of the police car is 40.13491 m/s
The true statements about generators would be :
They convert motion energy to electric energy
They use the relative motion of a magnet and a coil of wire.
Explanation:
Generators use the energy of the rotating coil in relative motion with magnets to induce a current within the wire. Generators are devices that convert energy into a voltage by the relative motion of the magnet and a coil that changes flux.
Answer:
The time it will take for the driver to reach Ottawa is 3 hours 32 minutes and 45 seconds
Explanation:
The given parameters are;
Speed of the car = 120 km/h
Distance from Toronto to Ottawa = 425.5 km
The formula for speed is given as follows;
Speed = Distance/Time
Therefore, to find the time duration it takes from Toronto to Ottawa, we have;
Time duration = Distance from Toronto to Ottawa/(Speed of the car)
The time duration = 425.5/120 = 3.54583 hours = 212.75 min = 12765 seconds
The time it takes from Toronto to Ottawa while driving at 425.5 km/h = 12765 seconds.
<span>Let m1=10kg and m2=5kg and for our calculations assume right is positive and up is positive (note: for block hanging, the x axis is vertical so tilt your head to help)
For m1
Sigma Fx = ma
T - m1gsin35 = m1a where T = tension
For m2
m2g - T = m2a
Add equation together
m1a + m2a = T-m1gsin35 + m2g - T
a(m1 + m2) = m2g - m1gsin35
a= (5*9.8 - 10*9.8*sin35)/(10 + 5)
a= -0.48m/s/s
So the system is moving in the opposite direction of our set coordinate system where we said right positive, its negative so its moving left therefore down the ramp</span>
