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.
I believe the answer is False
Answer:
°
Explanation:
Let's use the component method of vector addition:
Now, we know:
So:
Now lets calculate the magnitude of the vector B:
Finally its angle is given by:
°
Keep in mind that I added 180 to the angles of C and B to find the real angles measured from the + x axis counter-clock wise.
Explanation:
I haven't actually seen the answer I'm looking for but I think the answer is when temperatures are lower the wavelength is longer
The cyclist is moving by uniformly accelerated motion, with an initial velocity of
and an acceleration of
.
The acceleration is given by
where
is the final velocity and
is the time between the end and the beginning of the motion, and in our case it is 1.75 s. Therefore, from this relationship we can find the final velocity:
