Answer: Torque T = 40.7 Nm
Explanation:
Torque or turning effect is the rotational equivalent of linear force, i.e moment of force about a point.
Given that the force is applied perpendicular to the edge (angle 90°)
Torque can be represented by T;
T = FrSin∅ = Fr ( sin90 = 1)
T = force × distance
T = F × r
F = 55N
r = 74cm = 0.74m
T = 55N × 0.74m
T = 40.7 Nm
Answer:
The average speed is 8.0 km/h
Explanation:
We use the data for the return journey to calculate the distance travelled using the constant velocity equation:
s = v t =6*4=24km
Note I didn't change any units so the answer comes out in kilometres.
Now use the distance and time taken to travel to Guam to find the average speed:
v=st=24/3=8.0km/h
Answer:
Explanation:
An industrial system consists of inputs, processes and outputs. The inputs are the raw materials, labor and costs of land,transport, power and other infrastructure. The processes include a wide range of activities that convert the raw material into finished products.
If the object is moving in a straight line with constant speed,
that's a description of " acceleration = zero ".
Zero acceleration means zero net force on the object.
NO net force is 'required' to keep an object moving in a straight line
at constant speed. In fact, if there IS any net force on the object,
then either its speed or its direction MUST change ... there's no way
to avoid it.
None of this depends on the object's mass, or on the speed or direction
of its motion.
