Did Helen Keller get her sight back?
no she did not
How to determine the value of g?
That can be determined fairly easily with a pendulum. The period of the pendulum depends on the length of the pendulum and the value of "g".
Where was Helen Keller born?
Helen Keller was born in Tuscumbia, Alabama, United States. She was about 9 months when she lost her sight and hearing.
Value of g by simple pendulum?
You can build a simple pendulum - one that has most of its mass concentrated in a small place, at the end of the pendulum. Measure the pendulum's length, and measure how long it takes to go back and forth. Use the formula for the period of a pendulum, solving for "g".
Why does a pendulum lose time in summer and gain in winter?
Time period of pendulum is, T= 2π*SQRT(L/g) In summer due to high temperature value of 'l' increases which increases the time period of pendulum clock. Hence, pendulum clock loses time in summer. In winter due to low temperature value of 'l' decreases which decreases the time period of pendulum clock. Hence, pendulum clock gains time in winter.
What did Helen Keller come down with?
Scarlet fever. When it suddenly drops you could loes sight and hearing.
Does the mass of the pendulum bob affect the value of g why?
The value of gravitational acceleration 'g' is totally unaffected by changing mass of the body. We are not talking about weight of the pendulum. It is the value 'g' we are talking about, which remains unaffected by changing mass as: g= ((2xpie)2)xL)/T2 where, g= gravitational acceleration L= length of simple pendulum T= time period in which the pendulum completes its single vibration or oscillation
What is effect of changing mass of pendulum on value of 'g'?
yes it can change....
Did Helen Keller get her disabilities from a fever?
Yes, Helen Keller lost her sight and hearing due to an illness at the age of 19 months, which is believed to have been scarlet fever or meningitis.
Did a posionous butterfly cause Hellen Keller to lose her sight and hearing?
No, Helen Keller did not lose her sight and hearing due to a poisonous butterfly. She became deaf and blind after falling ill as a young child, which was likely due to a severe illness such as scarlet fever or meningitis.
When did Helen Keller lose her sight?
Helen Keller lost her sight and hearing in February 1882, when she was just 19 months old. This was the result of an illness accompanied by severe fever, which is thought to have been either scarlet fever or meningitis.
In measuring the period of a pendulum's motion with a stopwatch how could you best minimize the influence of reaction time?
In measuring the period of a pendulum's motion with a stopwatch, you can best minimize the influence of reaction time by measuring period at the maximum swing point, i.e. the point where the pendulum stops and then reverses. It is at that point that the pendulum is moving the slowest. You should also make your line of sight be perpendicular to the swing, in order to minimize parallax error; and you should have a mark of some kind that you can move around to the peak value, then recording the period between successive peak values.
