What a fan does is create a wind chill effect. ... By blowing air around, the fan makes it easier for the air to evaporate sweat from your skin, which is how you eliminate body heat. The more evaporation, the cooler you feel.
Answer:
a single closed path of electrical components including a voltage source
In this problem, we apply the equation regarding kinematics expressed as vf^2 = v0^2 + 2as vf eventually becomes zero because the ball stops in the end. a = -9.8 m/s2s = 2 metres this time
This gives initial velocity, vo equal to 6.26m/s
now 6.26-(-8.85) = 15.11m/s
change in velocity/change in time = average acceleration 15.11/(12/1000) = 1259.167 m/s^2
Answer:
Explanation:
Given that,
Mass of the clock, m = 108 kg
When the clock is not moving, force acting on it, 
For the clock in motion, force acting on it, 
To find,
Solution,
When an object is at rest, the force acting on it is called force due to static friction and if the object is in motion, the force acting on its called force due to kinetic friction.
Let 
is the coefficient of static friction. Force is given by :
Let 
is the coefficient of kinetic friction. Force is given by :
