Mechanical advantage of a machine is the ratio of the output force over the input force or M=Fo/Fi. Since M=1, Fi=Fo, or the input force is equal to the output force. This means that to raise the refrigerator that weighs 900 N, we need the same input force of 900 N, or Fo=Fi=900 N.

What is the process called in which water vapor and carbon dioxide retain heat?
saw5 [17]

The process in which water vapour and carbon dioxide traps heat is called the “greenhouse effect”.

 

The greenhouse effect is a natural phenomenon which occurs every day. To illustrate an example of this natural phenomenon, d<span>uring the day the Sun shines through the atmosphere. Earth's surface warms up because of the sunlight. Meanwhile at night in the absence of the sunlight, Earth's surface cools back and releasing the heat back into the air. However some of the heat is retained by the greenhouse gases (such as carbon dioxide and water vapour) in the atmosphere. This process what keeps our planet Earth warm and cozy at an average temperature of 16°C.</span>

When you pedal a bicycle, maximum torque is produced when the pedal sprocket arms are in the horizontal position, and no torque
poizon [28]

Answer:

This is because when the pedal sprocket arms are in the horizontal position, it is perpendicular to the applied force, and the angle between the applied force and the pedal sprocket arms is 90⁰.  

Also, when the pedal sprocket arms are in the vertical position, it is parallel to the applied force, and the angle between the applied force and the pedal sprocket arms is 0⁰.

Explanation:

τ = r×F×sinθ

where;

τ is the torque produced

r is the radius of the pedal sprocket arms

F is the applied force

θ is the angle between the applied force and the pedal sprocket arms

Maximum torque depends on the value of θ,

when the pedal sprocket arms are in the horizontal position, it is perpendicular to the applied force, and the angle between the applied force and the pedal sprocket arms is 90⁰.

τ = r×F×sin90⁰ = τ = r×F(1) = Fr (maximum value of torque)

Also, when the pedal sprocket arms are in the vertical position, it is parallel to the applied force, and the angle between the applied force and the pedal sprocket arms is 0⁰.

τ = r×F×sin0⁰ = τ = r×F(0) = 0 (torque is zero).
