Explanation:
<em>Work done by torque = magnitude of force * perpendicular distance between the point of action and point(axis) of rotation.</em>
Answer:
The angle is degrees.
Explanation:
Se the attached drawing if you need a visual aid for the explanation. Let be the angle of elevation of the plante which in itself is the same drop angle that the pilot measures. Let be the horizontal distance from the target and the height of the plane. We know that the package is dropped without any initial vertical speed, that means that it has a y-position equation of the form:
If we set we are setting the condition that the package is in the ground. We can then solve for t and get the flight time of the package.
.
If the flight time is - then the distance b can be found in meters by taking into account that the horizontal speed of the plane is .
The angle is thus
degrees.
For this, we need the formula:
V = k q / r
where k is the Coulombs law constant = 9 x 10^9 N
q is the charge of the hydrogen nucleus (proton) = <span>1.6 x 10^-19 C</span>
r is the distance
Simply plug in the values and solve for V
Mathematically, to compute for the wavelength, λ, we have
where v is the velocity and f is the frequency.
As we can see here, given that velocity is constant, wavelength increases as frequency decreases. This shows that wavelength is inversely proportional to frequency.
Answer: Wavelength and frequency are inversely related to each other.
the answer is true because i think its true not 100 percent sure
