The work done to lift the block of ice is calculated as follows: Work = force × distance = 90N × 3m = 270 Joules.
The potential energy (PE) of the block of ice when lifted to a height of 3m is equal to the work done to lift it, which is 270 Joules.
The force needed to move a block is directly related to the distance it travels. As the distance the block travels increases, more force is required to overcome friction and other resistive forces acting against the motion. This relationship is commonly described by the work-energy principle.
To calculate the heat needed to melt a block of ice at its melting point, you need to know the mass of the ice block, the specific heat capacity of ice, and the heat of fusion of ice (or latent heat of fusion). The formula to calculate this heat is Q = m * ΔHf, where Q is the heat energy, m is the mass, and ΔHf is the heat of fusion.
Work = force x distance = (4 x 10) = 40 newton-meters = 40 joules
The work done by a block on an incline is calculated using the equation: work = force * distance * cos(theta), where force is the component of the weight of the block that acts parallel to the incline, distance is the displacement of the block along the incline, and theta is the angle between the force and the displacement vectors.
When a block is floating in a fluid, the net force in the vertical direction is zero. This is because the weight of the block is balanced by the buoyant force acting in the opposite direction, resulting in equilibrium.

-- The equal and opposite forces on it are the vertical forces ... the weight of the block downward and the normal, constraint force of the surface upward. Since the vertical forces are equal and opposite, the net vertical force on the object is zero, and it has no vertical acceleration. -- Nobody ever said that the block needs force to keep moving. In fact, it doesn't. Once it's moving horizontally, no force is needed to keep it moving horizontally. If it weren't for that pesky friction where it touches the surface, it would keep moving forever with no force on it.
Vertical blinds supposedly block out more of the sunlight.
It's called city-block distance, because it is calculated as if on each pixel between your two coordinates stood a block (house) which you have to go around. That means, you can only go along the vertical or horizontal lines between the pixels but not diagonal. It's the same like the movement of the rook on a chess field.

You can use a tape measure to measure the length and width of the block and then multiply these two dimensions to calculate the area. Alternatively, you can also use a laser distance measuring tool for more accurate measurements.
To calculate the number of concrete blocks needed for a building, you first need to determine the area of one block and then divide the total building area by the block area. Concrete block sizes vary, so you will need to know the dimensions of the block you plan to use. Once you have that information, divide the total building area (25x30) by the block area to find the number of blocks needed.
