What is the velocity of a 4.5 Pound object falling thirty feet?
Ignoring air resistance ... Any object dropped near the Earth's surface reaches a speed of 43.9 feet per second after falling 30 feet. The velocity is 43.9 feet per second down. The object's weight makes no difference.
What has more pressure on an object 260 feet depth of water or 35000 feet of altitude?
The 260 feet of water: at that depth, there is the weight of the water and the atmosphere on top of it.
When an object is lifted 6 feet off the ground it gains a certain amount of potential energy If the same object is lifted 12 feet off the ground its potential energy is?
Double the first potential energy.
If an object moved 33 feet in 5 seconds what is its speed?
Speed = (distance) / (time) = 33/5 = 6.6 feet per second
When an object is lifted 12 feet off the ground it gains a certain amount of potential energy if the same object is lifted 36 feet off the ground its potential energy is?
The potential energy of an object can be calculated using the simple formula Potential Energy = mass*acceleration due to gravity*distance above ground. For simplification, we can call the mass m and the acceleration g. Using these values, the object will have a potential energy of 12m*g when it is 12 feet off the ground. When it is 24 feet off the ground, it will have an energy of 24*m*g. This is nothing more than twice the value we calculated before, so we can say that the object's potential energy at 24 feet is twice its potential energy at 12 feet. In order to give an exact value, we would need to know the mass of the object as well.
When a person or object cannot be clearly discernible at a distance of 500 feet?
Fog, mist, dark
What does 20 100 vision mean?
20/100 Vision would mean that the average person can see clearly at 100 feet you must be 20 feet away to see the object clearly.
What does it mean to have 20 15 vision?
It means the average person can see clearly at 20 feet what you can see clearly at 15 feet.
What is 3280.8399 feet in miles?
3,280.8399 feet = 0.621371193 miles
What object is 1000000 feet long?
A 304800 meter object is 1000000 feet long!
What is 1200 feet long wall in linear feet?
Feet are the same as linear feet. Linear just distinguishes them clearly from square feet or cubic feet.
An object is released into the air at an initial height of 6 feet and an initial velocity of 30 feet per second The object is caught at a height of 7 feet How long is the object in motion?
23 sec
Compare nearsightedness and farsightedness in terms of defects?
In nearsightedness, the eyeball is elongated and the focal point thus falls short of the retina. This results in good vision for objects very close to the face, but poor vision at any significant distance (even beyond a few feet, for any level of nearsightedness. Conversely, in farsightedness, the focal point is never reached, before the retina. Thus, objects which are near cannot be seen clearly. However, distance sight is preserved.
What is meant by 20-70 vision?
It means you can see clearly at 20 feet what a normal person could see clearly at 70 feet. You may be needing glasses just for driving.
What is an object that is 9 feet long?
anaconda
