When detergent is added to pure water, the surface tension decreases. Detergent molecules disrupt the cohesive forces between water molecules at the surface, reducing the surface tension. This allows the detergent solution to spread more easily and penetrate surfaces, enhancing ...

Small pieces of camphor dance on the surface of water due to surface tension. When camphor is placed on water, it rapidly sublimes, releasing molecules into the air. As these molecules push against the surface tension of the water, they ...
A person at rest in the middle of a horizontal plane of perfectly smooth ice can bring themselves to the shore by using the first law of motion. This law states that an object at rest will remain at rest ...
Since the car maintains a constant velocity, there’s no additional force acting on the ball while it’s airborne. Therefore, the ball travels vertically upward after being thrown and then falls straight back down relative to the car’s frame of reference. ...
The synchronizing satellite rotates around the Earth in a West to East direction. This rotation synchronizes with the Earth’s rotation, facilitating stable positioning relative to a point on the Earth’s surface. This alignment is essential for functions such as communication ...
