Answer:
The wavelength in miles is <u>0.1165 miles</u>.
Explanation:
Given:
Wavelength of the radio wave is 187.37 m.
Now, the wavelength is given in meters.
We need to convert the wavelength from meters to miles.
In order to convert meters to miles, we have to use their conversion factor.
We know that,
1 meter = 
Therefore, the conversion factor is given as:

So, the wavelength in miles is given as:

Hence, the wavelength in miles is 0.1165 miles.
Answer:
The speed of the vehicle was 21 m/s
Explanation:
Momentum can be defined as mass in motion
Momentum depends on the variables mass and velocity
The momentum of an object is equal to the mass of the object times the
velocity of the object
The given is:
→ A Jeep Rubicon has a mass of 2,630 kg
→ With a momentum of 55,200 kg m/s
We need to find the speed of the vehicle
→ The momentum = mass × speed
Substitute the values above in the rule
→ 55,200 = 2,630 × speed
Divide both sides by 2,630
→ speed = 20.99 ≅ 21 m/s
<em>The speed of the vehicle was 21 m/s</em>
Given data:
* The extension of the steel wire is 0.3 mm.
* The length of the wire is 4 m.
* The area of cross section of wire is,

* The young modulus of the steel is,

Solution:
The young modulus of the steel in terms of the force and extension is,

where F is the force acting on the steel wire,, l is the original length of the wire, dl is the extension of the wire, and A is the area,
Substituting the known values,

Thus, the force which produce the extension of 0.3 mm of the steel wire is 31.5 N.
At what angle torque is half of max
V ( initial ) = 20 m/s
h = 2.30 m
h = v y * t + g t ² / 2
d = v x * t
1 ) At α = 18°:
v y = 20 * sin 18° = 6.18 m/s
v x = 20 * cos 18° = 19.02 m/ s
2.30 = 6.18 t + 4.9 t²
4.9 t² + 6.18 t - 2.30 = 0
After solving the quadratic equation ( a = 4.9, b = 6.18, c = - 2.3 ):
t 1/2 = (- 6.18 +/- √( 6.18² - 4 * 4.9 * (-2.3)) ) / ( 2 * 4.9 )
t = 0.3 s
d 1 = 19.02 m/s * 0.3 s = 5.706 m
2 ) At α = 8°:
v y = 20* sin 8° = 2.78 m/s
v x = 20* cos 8° = 19.81 m/s
2.3 = 2.78 t + 4.9 t²
4.9 t² + 2.78 t - 2.3 = 0
t = 0.46 s
d 2 = 19.81 * 0.46 = 9.113 m
The distance is:
d 2 - d 1 = 9.113 m - 5.706 m = 3.407 m
