Answer: Option (C) is the correct answer.
Explanation:
Conduction is a process where transfer of heat occurs when two objects of different temperature are held next to each other. Heat gets transferred from hot substance to cool substance.
For example, when a copper pot is placed over a stove then heat transfers from stove to the copper pot.
Thus, we can conclude that heat would best be transferred by conduction between a stove and a copper pot.
Answer:
84.6 J
Explanation:
The work done by the force is given by
where
W is the work done
F = 15 N is the force applied
d = 6.0 m is the displacement
is the angle between the force's direction and the displacement
Substituting the numbers into the equation, we find
V= s/t = 400/4.5=800/9 (km/h)
Answer:
The force is 
Explanation:
The moment of Inertia I is mathematically evaluated as
Substituting 
for M(Mass of the wheel) and 
for 
(Radius of wheel)
The torque on the wheel due to net force is mathematically represented as
Substituting 135 N for 
(Force acting on sprocket),
for 
(radius of the chain) and F is the force acting on the sprocket due to the chain which is unknown for now
This same torque due to the net force is the also the torque that is required to rotate the wheel to have an angular acceleration of 
and this torque can also be represented mathematically as
Now equating the two equation for torque
Making F the subject
Substituting values
