What else can I help you with?
Why every object left above the surface of the earth without a support falls down ward?
Objects fall downward when unsupported due to the force of gravity, which pulls objects toward the center of the Earth. This force causes objects to accelerate toward the ground at a rate of 9.8 m/s^2. This phenomenon is described by Newton's law of universal gravitation.
What do you see when you look into the periscope?
When you look into a periscope, you see a magnified view of what is above the surface of the water. Periscopes are commonly used on submarines to enable viewing above the waterline without the vessel having to surface.
What kind of objects float above water?
Objects that are less dense than water will float on the surface. This can include materials like wood, plastic, and certain types of metals. In general, objects with a density less than 1 g/cm3 will float.
Hyphae above the surface of an object is for?
Hyphae above the surface of an object is for absorbing nutrients and moisture from the environment to support the growth and development of the fungus. This structure helps the fungus explore new resources and extract essential nutrients for its survival and reproduction.
What forces act in water?
In water, buoyancy, gravity, surface tension, drag, and pressure are some of the forces that act on objects. Buoyancy is the upward force exerted by water that allows objects to float. Gravity pulls objects down towards the bottom of the body of water. Surface tension is the force that allows water molecules to stick together at the surface. Drag is the resistance force experienced by objects moving through water. Pressure increases with depth due to the weight of the water above pushing down.

Which of these does the atmosphere exert pressure on?
The atmosphere exerts pressure on all objects and surfaces within it, including buildings, people, and the Earth's surface. This pressure is a result of the weight of air molecules above pressing down on objects below.
Why is the gravitational potential energy of an objects 1 meter above the moons surface less than its potential energy 1 meter above Earths surface?
because the value of gravitational force of earth is greater than that of moon.
What man made objects are in the therospere?
The thermosphere is an atmospheric layer where man-made objects such as satellites and space stations orbit the Earth. These objects can be found at altitudes ranging from 80 km to 550 km above the Earth's surface.
What does protruding?
I t means Extending out above or beyond a surface or boundary

Which instrument is used to observe objects on the surface from a submarine?
A periscope is used to observe the surface from a submarine
The support disks hold cable off the pavement surface what is the minimum cable height above the pavement?
2 inches

Which do hyphae, which extend above the surface of wherever a fungus is living, typically support?
Hyphae that extend above the surface of where a fungus is living typically support the reproductive structures of the fungus, including spore-producing structures like mushrooms or fruiting bodies. These structures are important for the fungus's reproduction and dispersal of spores.
How does air above a cold surface?
how does air above cold surface move
