Answer: 3.63 Nm
Explanation:
from the question we were given the following
mass = 1.7 kg
length of the string (r) = 2.5 ,m
angle θ = 5 degrees
acceleration due to gravity (g) = 9.8 m/s
we can calculate the torque using the formula Torques = m x g x r x sin θ
torque = 1.7 x 9.8 x 2.5 x sin 5
torque = 3.63 Nm

Explanation:
4 degrees C turns out to be the temperature at which liquid water has the highest density. If you heat it or cool it, it will expand. ... Ice floats on top of lakes, preventing evaporation (and convection in the frozen layer), and lakes stay liquid underneath, allowing fish and other life to survive.
We know that the Pythagorean theorem applies only to right triangles, therefore the original vectors must be parallel to the legs of a right triangle.
In other words, they must be orthogonal (i.e. perpendicular to each other) in order that the Pythagorean theorem applies.
