Why should a microscope slide be held by its edges?
A microscope slide should be held by its edges to avoid leaving fingerprints or oils from the skin on the slide surface, which can interfere with the clarity of the image under the microscope. Handling the slide by its edges also helps prevent accidental damage or smudging of the sample on the slide.
Where friction is useful or nuisance for us?
Lots of friction in the world, some useful, some harmful. But friction is not something that merely exists or does not. It can be measured, and a thing can be said to have too little, too much, or a good amount. If you get a rope burn, when a rope you are holding slips in your hands, that is harmful friction. Friction causes a car to stop when the breaks are put on. An ice skater uses skates because they get traction with their sharp edges, but there is low friction on the blade to slide on the ice. If you were on a roof made of asphalt tiles, and the roof were not too steep, it would be friction that holds you in place. You would know better than to go on the roof if it were covered by ice, because the friction would be too low - it would be slippery.
What are the forces involved in skiing?
There is a fair amount of physics involved, but the general picture is simple. The force of gravity is pulling the skier down the slope. It is the "prime mover" here. There will be air friction ("drag") on the individual, and a bit of friction (though not much) on the bottom surface of each ski where it is in contact with the snow. And the poles are used to "lift" the skier and allow him to "reposition" his skis. But the real "biggie" here other than gravity is the force created when the edges of the skis "cut into" the snow and allow the skier to redirect his path of travel. The skier shifts his weight to put more on the outer ski and use the edge to slice into the snow and allow him to move laterally (across) a slope. It is true that the skier will have considerable momentum after he gets going, but the edges of the skis will allow him to change course and control his rate of descent. The force on the edges as they "bite into" the snow are the other key factor that makes skiing what it is.
How do you reduce the friction of axles rotating in the chassis of a mousetrap car?
To reduce the friction of axles rotating in the chassis of a mousetrap car, you can try using lubricants like graphite or silicone on the axles. Make sure the axle holes in the chassis are drilled accurately to reduce binding, and use smooth materials for the axle construction. Additionally, ensuring proper alignment and spacing of the wheels can help minimize friction.
What lens is thicker at the edges?
A concave lens is thicker at the edges compared to the center.
Why should a microscope slide and coverslips be held their edges?
A microscope slide and coverslip should be held by their edges due to leaving fingerprints and/or debris and how easily breakable they are. Leaving fingerprints or debris on either a slide of coverslip will alter the view under the microscope.
Name two objects or structures within the environment that have horizontal edges?
Two objects or structures within the environment that have horizontal edges are the floor and a string.
What are two objects or structures within the environment that have vertical edges?
Trees and mountains have vertical edges, as do buildings and telephone poles.
Two objects or structures within the environment that have vertical edges?
telephone pole , tall building , a rocket launching
What happens when edges of tectonic plates when pushed together?
they shout help!!Vibrate and course friction
Why should you hold a microscope slide by the edges?
You should hold a microscope slide by the edges to avoid smudging or getting fingerprints on the glass surface. This helps ensure a clear and unobstructed view when examining the slide under a microscope.
What can you infer about a rock that had smooth edges?
A rock with smooth edges may have undergone erosion from water or wind over time. The smooth edges suggest that the rock has been worn down and rounded by abrasion, potentially indicating that it has been transported and exposed to repeated friction.
Why should a microscope slide be held by its edges?
A microscope slide should be held by its edges to avoid leaving fingerprints or oils from the skin on the slide surface, which can interfere with the clarity of the image under the microscope. Handling the slide by its edges also helps prevent accidental damage or smudging of the sample on the slide.
What is the total number of edges can a square base pyramid has?
A 4-sided pyramid, also known as a square pyramid, has 8 edges. This is the more-common shape for pyramidal structures. There are 4 edges where the triangular sides meet each other, and there are 4 more edges where the 4 triangular sides meet the square base.
What is the difference between automatons and kripke structures?
They are veery similar - instead of atomic propositions automatons have letters and they appear on the edges rather than in the states. Plus automatons have accepting states which kripke structures don't.
What is a lobed leaf and how does it differ from other types of leaf structures?
A lobed leaf is a leaf with deep indentations or divisions along its edges, creating distinct lobes. This differs from other types of leaf structures, such as simple leaves with smooth edges or compound leaves with separate leaflets, because lobed leaves have these distinct lobes that give them a unique appearance.
How can I make my own inflatable structures?
To make your own inflatable structures, you will need a durable material like PVC or vinyl, a way to seal the edges such as heat sealing or sewing, and a way to inflate the structure like a pump or fan. Design your structure, cut the material to size, seal the edges, leaving an opening to inflate, and then inflate the structure to the desired pressure.
