On Mars the astronaut could hike for thousands of miles and explore incredible canyons and mountains, so he may not be as bored as he would become in a cave. On Mars the astronaut could use solar panels to power all of his equipment for the entire year. On Mars, the communication would be wireless. On Mars there would be sunsets and sunrises and beautiful stars to look at. So the cave experiment ( done several times already ) would not prove how long an astronaut could survive on Mars. On Mars, an astronaut could have robots to help him do things. He could possibly travel by bicycle or on a small electric motorbike. He could probably even explore caves.
Assault by contact refers to a physical attack on someone without their consent, where there is physical contact involved but no significant physical harm inflicted. It can include actions like pushing, slapping, or grabbing someone without their permission.
Yes, proximity switches can be actuated without physical contact. They work by detecting changes in the electromagnetic field around them when an object comes within range, triggering the switch without the need for direct contact.
Because, no environment can survive without water.

Yes from bedding etc
One effective way to eliminate a bug without making physical contact is to use a vacuum cleaner or a bug trap. These devices can capture the bug without the need for direct contact, allowing you to dispose of it safely and easily.
Contact forces involve direct physical contact between objects, such as friction and normal force. Non-contact forces act at a distance without physical contact, such as gravity, electrostatic, and magnetic forces.
Human contact is essential for emotional well-being and mental health. Prolonged isolation can lead to negative consequences such as loneliness, depression, and cognitive decline. While a person may physically survive without human contact, their overall health and quality of life would likely deteriorate without social interaction.
Yes, a .50 caliber round can cause harm without making physical contact with a person through its shockwave and blast effects.
most of the cells are in contact with a watery environment
Plants achieve reproduction without needing physical contact.
