no she did not
Helen Keller was born in Tuscumbia, Alabama, United States. She was about 9 months when she lost her sight and hearing.
No, the value of acceleration due to gravity (g) would not be affected by changing the size of the bob in a simple pendulum experiment. The period of a simple pendulum is determined by the length of the pendulum and the gravitational acceleration at that location, not the size of the bob.
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
When the kinetic energy of a pendulum is at half its maximum value, the potential energy it possesses will also be at half its maximum value. This is because the total mechanical energy of the pendulum (the sum of kinetic and potential energy) remains constant throughout its motion.
Changing the length or mass of a pendulum does not affect the value of acceleration due to gravity (g). The period of a pendulum depends on the length of the pendulum and not on its mass. The formula for the period of a pendulum is T = 2π√(L/g), where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.
Scarlet fever. When it suddenly drops you could loes sight and hearing.
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.
yes it can change....
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.
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.
