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.

What type of work is being done when pulling?
The same type as is done when pushing, shoving, rolling, lifting, wiggling etc. ... a force acting through a distance.
How much work is done when a 700 N refrigerator is lifted straight up a distance of 4 meters in joules?
Work is done in lifting is equal to work done in opposing gravity. Work done in opposing gravity = weight times distance = 700 x 4 =2800 joules
How much work is done in lifting a 20 kg object through a distance of 0.40 m Use g 10 ms?
Work Done= Force X Distance moved by the object in the direction of the force = 20kg X 10N/kg X 0.40m = 80J
How much work is done when a ball weighing 20 Newtons is lifted a vertical distance of 2 meter?
Work = force x distance = 20 x 2 = 40 newton-meters = 40 joules
Work done in lifting and lowering an object?
potential energy
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.

Is both the work done are same when you travel the same distance along horizontally and vertically?
No, unless both are zero. No work is done in a horizontal motion. mGh is work in a vertical direction.

Work = force x distance = 20 x 2 = 40 newton-meters = 40 joules
How much work is done by the surface molecules pushing upward on the object when it moved horizontally?
If there is no vertical motion, then no work is done by any vertical forces.

What kinds of tasks get done with the help of a lever?
lifting heavy objects
How is power defined in physical science?
In physics, Power is the amount of work done in a given amount of time. (Note: Work, in the scientific sense, is the amount of force multiplied by vertical distance traveled.)
What is the difference between horizontal and vertical motion?
Our jumping is a vertical motion, while walking is a horizontal motion. Exercises are done by both horizontal and vertical motion.
If you perform 40 joules of work lifting a 10-N bix from the floor to a shelf how high is the shelf?
The height of the shelf can be calculated using the formula: work done = force x distance. In this case, the work done is 40 J, the force is 10 N, so the distance (height of the shelf) can be calculated as 40 J / 10 N = 4 meters.
