Answer:
Force = 186 N
Explanation:
Torque is the rotational equivalent of linear force. It can be easely calculated using the formula :
Where is a vector that from the origin of the coordinate system to the point at which the force is applied (the position vector),
is the applied force.
The easiest way of computing the force is by setting the origin of the coordinate system to the lowest point of the torque wrench. By doing this we have that (the magnitud of the position vector) is 35cm.
Before computing the force we need to set all our values to the international system of units (SI). The torque is already in SI. The one missing is the length of the torque wrench (it is in centimeters and we need it in meters). So :
Now using the torque formula:
Where is the smaller angle between the force and the position vector. Because the force is applied perpendiculary to the position vector
, thus :
so the force is approximately 186 N.
Answer:
therefore critical angle c= 69.79°
Explanation:
Canola oil is less dense than water, so it floats over water.
Given
which is higher than that of water
refractive index of water
to calculate critical angle of light going from the oil into water
we know that
now putting values we get
c=
c=69.79°
therefore critical angle c= 69.79°
