work is defined as mass x acceleration x distance
assuming you are lifting vertically against gravity only, you can assume:
mass = 8kg
accel = 9.81 metres / second / second
distance = 1 m
8*9.81*1 = 78.48
SI unit being joules. if you were to perform this amount of work in 1 second you would consume 78.48 watts, i.e. an equivalent amount of energy that 1 light bulb would burn in 1 second of illumination.
well you know i have the same home work con physics haha and it's chapter 8 right second question haha. i think; if you want to lift a barbell three times as high you have to give three times the work (W)
Using an inclined plane decreases the amount of force needed to lift an item vertically. By spreading the work over a longer distance along the plane, the force required to lift the item is reduced. This makes it easier to lift heavier objects or lift objects to a greater height.
The work done to lift the log can be calculated using the formula: Work = Force x Distance. In this case, the force is 5000 N and the distance is 5 meters. Therefore, the work required to lift the log 5 meters would be 5000 N x 5 m = 25000 Joules.
Holding a watermelon in your hands is not considered work in the physics sense. Work is defined as force applied over a distance in the direction of the force, whereas holding a watermelon is a static action that does not involve movement over a distance.
The work required to lift the concrete block can be calculated using the formula: work = force x distance. If the concrete block weighs 1 kg, then the force required to lift it against gravity can be calculated as force = mass x gravity, where gravity is approximately 9.81 m/s^2. So, the work done would be work = 1 kg x 9.81 m/s^2 x 3.8 m.

The work required to lift the object is given by the formula: work = force x distance. The force required to lift the object is equal to its weight, which is mass x acceleration due to gravity. Therefore, the work done would be the weight of the object x height it is lifted: W = (2.90 kg x 9.81 m/s^2) x 9.4 m = 262.38 Joules.
For this type of procedure, it's best to use bleach. A high lift color will not be strong enough to lift artificial pigment.
The minimum energy required to lift an object is equal to the work done, which is given by the formula: work = force x distance. In this case, the work done would be 200 N (force) x 20 m (distance) = 4000 joules. Therefore, the minimum energy required to lift the object weighing 200 N to a height of 20 meters is 4000 joules.
To calculate the work required to lift the box, you can use the formula: work = force × distance. In this case, the force is equal to the weight of the box (30 kg * 9.8 m/s^2) and the distance is 1 meter. So the work required would be 294 joules.
The work required to lift the concrete block can be calculated using the formula: Work = force x distance. First, you need to calculate the force required to lift the block, which is equal to the weight of the block multiplied by the acceleration due to gravity (9.81 m/s^2). Then, multiply the force by the distance lifted (2.2 m) to find the work done.
