Is the ruler drop test valid?
The ruler-drop test has acceptable test-retest reliability that compares favorably with computerized measures of reaction time.
Which finger has the fastest reaction time?
The fingers on the outside — i.e. the thumb and little finger — therefore react faster than the middle finger, which is exposed to the “cross fire” of two neighbours on each side.
Did you catch the ruler faster with your eyes open or closed?
Your dominant hand (right or left) will catch the object faster when your eyes were open.
Did you catch the ruler faster with your eyes open or closed Brainly?
Answer Expert Verified The data tells us that the total time in catching the ruler in eyes open is 2.95 seconds which is lesser compared to the total time during eyes closed which is 4.12 seconds.
Did you catch the ruler faster with your left hand or right hand Why might this be so?
The dominant hand will catch the ruler faster as it is skilled and the brain sends signals in fractions of the second in this case the primary response takes place in this case. Thus, the correct answer is – the dominant hand of the individual.
Do you feel the end of the ruler pushing against your hands?
Answer. Answer: Q1:Yes,A ruler has two ends that’s why if you hold it on both sides you can feel the ends of the ruler pushing against your hands. Q3:The deformation of the ruler creates a force in the opposite direction, known as a restoring force.
What will happen to the ruler as you release date?
Answer: When the Ruler is bent the energy stored in it will be potential energy, When the ruler will be released this potential energy will be then converted into the Kinetic energy as a result the ruler will move Vibrations.
What will happen to the ruler as you take away your left hand quickly?
ANSWER. Ruler vibrates as it snaps back to its original position. The stored energy is released.
What will happen to the paperclips if you have struck the table hard enough?
If you have struck the table hard enough the paper clips will start to vibrate back and forth.
What will happen to the paper clips if you have?
Answer: The paper clips will begin to vibrate back and forth if you have hit the table hard enough. Explanation: Thanks to the “spring” repulsive nature of the atomic lattice, vibrations that reverberate through the rest of the nearby structure are produced by warping .
What happens when you drop the stone Brainly?
Answer: When the stone is dropped, there will be presence of gravity of Earth. The more the mass the object is, gravity will increase exponentially.
What happened when you dropped the stone?
Answer Expert Verified When you drop the stone tsunami occurs. Japanese people in ancient times use stone markers as tsunami warnings. The tsunami stones serve as warnings to descendants to avoid the same suffering of their ancestors because of the tsunami. A tsunami is a dangerous big wave from the ocean.
What happens when you drop the stone into the water?
If one drops a stone into a pond, a very rapid, thin jet of water spouts upwards. A cavity forms behind the object during impact on the water surface. This cavity is subsequently compressed by hydrostatic pressure, which leads to the formation of the jet.
What happens when you drop a piece of stone in a glass half filled with water?
Water level will rise up by a volume equal to the volume of the stone and if the volume of the stone is more than the empty space in the glass, water will overflow the glass. per Archimedes experiments, the water will be displaced an amount to equalize the mass of the stone.
What will happen if you drop a piece of chalk and sponge into a glass of water?
Answer. chalk particle will little distributeand the air from sponge come out .
What happened when you place the stone in the jar?
As stated by Archimedes’ Law, an object immersed in a fluid experiences a buoyant force that is equal in magnitude to the force of gravity on the displaced fluid. If you try to put a rock in a jar filled with water, you can observe that the water inside has increased a little.
What happen to the water level as stones are added into the glass?
If you drop small stone into a glass which filled upto the brim level, still nothing will happens. Because stone has the property to absorbs water without any volumetric changes. There will be strong cohesive force works between water and the stone.
Why can’t you see a penny under a glass of water?
When the cup is filled with water, the penny disappears. This happens because of refraction. As light travels through the sides of the glass and the water, it’s refracted and never reaches our eyes, which makes the penny seems to disappear.
Why do people put coins in their sink?
Very often your luggage comes equipped with clothing clips inside. You can use these clips to keep your toothbrush elevated and away from potential germs. If you find yourself with clothes to be washed, put a plastic bag over the sink’s drain and weigh it down with coins to make sure the sink basin fills up enough.
Why did the coin rolling on the floor slow down and eventually stop?
Friction finally causes the penny to slow down and to stop. It gets lower and lower inside the balloon because of our old friend, gravity, too. While the object’s mass stays the same, its speed drops because of friction against the balloon and moves lower because of gravity.
