Answer:
196.34 °F
Explanation:
To convert from degrees celsius to degrees fahrenheit, use this equation:
(°C * 9/5) + 32 = °F
So, using this equation:
(91.30 * 9/5) + 32 = °F
196.34 + 32 = °F
°F = 196.34
Hope this helps!
Answer:
We know that the torque can be calculated as follows:
T = rpsinα
With r being the distance of the body from the center of the circumference he has as trajectory, p being the momentum of the body and sinα being the sine of the angle between the 2 vectors: r and p.
It's pretty obvious that T is directly proportional to the momentum, that can be written as p = m·v, with m being the mass of the object and v the velocity of the object.
Coulomb's law:
F = k×q₁×q₂/r² where k ≈ 9.00×10⁹NC⁻²m²
Given values:
q₁ = +1.0C
q₂ = -1.0C
F = 650N
Substitute the terms in Coulomb's law with our given values. We will have to use the absolute value of q₂ to so the algebra works out. Solve for r:
650 = 9.00×10⁹×1.0×1.0/r²
r = 3721m
Taking significant figures into account:
<h3>r = 3700m</h3>
