They require the same amount of work because the formula for work is force times distance.

What usually requires less work lifting or sliding?
Sliding
How much work is done in lifting a 600kg sack of rice to a vertical distance of 10m?
Just use the formula for gravitational potential energy:GPE = mgh Where m is the mass, g the gravity (around 9.8, in SI units), and h the height.
With regard to the object-lifting examples traced in lesson 3 the ima is equal to the distance divided by the distance?
effort, resistence

An inclined plane makes work easier by increasing the distance an object must be moved and changing what other factor?
Moving an object up an inclined plane requires less force compared to lifting it straight up. An inclined plane makes work easier by increasing the distance an object must be moved and changing the height that it spans.decreasing the force.
Which requires more work lifting a 100-kilogram sack a vertical distance of 2 meters or lifting a 50-kilogram sack a vertical distance of 4 meters?
They are the same- weight x distance equals weight times distance.
Which requires more work lifting a 50-kg sack a vertical distance of 2 m or lifting a 25-kg sack a vertical distance of 4 m?
work= force x distance, so both require work
What is a Distance Multiplier?
DM, established on the basis of results of empirical studies that suggest physical stress increases as the vertical distance of lifting increases. Value = (0.82+4.5/D) (metric) or (0.82+1.8/D) (US system) V= vertical distance of the hands from the floor.
Why does a ramp not reduce the amount of work. Please explain in words or with numbers?
Assuming 100% efficiency, the amount of work depends on the weight and the vertical distance (that is, opposite to the pull of gravity) moved. If you use a ramp then you reduce the force by an amount k, that's true, but the distance you have to push in the direction of the force is multiplied by k. The work done is [original force]/k times [vertical distance]times k and the k cancels out. For vertical lifting k=1.
Does lifting a 25 bag N of sugar 1 meter above the floor requires 25N m of work?
I suspect it is. Someone correct me if I'm wrong, but Work = force by distance.

What is convectional lifting?
Convective lifting is due to vertical instability. Convective current will form in order to transport the building heat energy at the surface upwards and to bring down cooler air aloft.

What sport do you use your pectorals in?
any sport that requires your arms because it helps with lifting and pushing and pulling
What is the angle of pull chosen at the elbow joint and why it is chosen as opposed to other angles when lifting a television set as you help your roommate move in requires appropriate lifting techniq?
90 degrees
