yes. because by light now a days we are giving laser tratements in kidneas etc by this way i can tell light can push a solid.
No, using a stick to push an object is an external force, not a muscular force. Muscular force comes from the contraction of muscles in the body.
A soft drink can would not be a good object to use when applying the two-second rule, as it is too light and might be easily blown away by wind or affected by external factors, leading to an inaccurate measurement of the following distance between vehicles. It's best to use a more stable and solid object for a more reliable estimation.
In finding the density of a rectangular solid object, you can simply calculate it by dividing the mass by the volume using the formula density = mass/volume. However, for an irregular solid object, you may need to use techniques like displacement method or water displacement method to determine its volume before calculating the density.
The best way to push an object is to position yourself behind it, bend your knees, place your hands on the object, and then push using the strength of your legs and lower back while keeping your back straight to avoid injury. It's important to use proper body mechanics and not to strain or overexert yourself while pushing.
Actually, its not. It depends on the direction of the force vector use to push or pull. If the two directions are equal, and the position of the force vectors are consistent with each other, then the amount of force to push would be the same as the amount of force to pull. You are probably realizing by now that when you pull an object, there is a tendency to lift it up from the surface, reducing friction, while when you push an object, the tendency is to push it down on the surface, increasing friction. This is why you have to be very careful and consistent in how you measure things.
we use force
No. If light were to become a solid it would cease to be light. What about the quantum method in physics concerning light.
The door is a solid object.
I believe it is kinetic energy.

We use force to push an object. The SI unit of force is Newton. Newton is the force which can move a body of mass 1 kg with a speed of 1m/s.
Either litres or cubic metres.
To measure the solid volume of an irregular object, you can use a graduated cylinder filled with water. By submerging the irregular object in the water, you can measure the change in water level, which corresponds to the object's volume. Alternatively, you could use a displacement method with a volumetric flask or a beaker, ensuring that the object is fully submerged for an accurate measurement.

use a ruler to measure the lenght of each side of the object
