What is u should know it bc u should answered it already
Explanation:
Answer:
Mass, m = 2.2 kg
Explanation:
It is given that,
Frequency of the piano, f = 440 Hz
Length of the piano, L = 38.9 cm = 0.389 m
Tension in the spring, T = 667 N
The frequency in the spring is given by :

is the linear mass density
On rearranging, we get the value of m as follows :


m = 0.0022 kg
or
m = 2.2 grams
So, the mass of the object is 2.2 grams. Hence, this is the required solution.
Hypothesis: The water will squirt far.
Indep.V.: Height of hole.
Depend.V.: Range of squirt
Constant: Everything that isnt the independant var. such as filled liquid.
Control: None,I believe.
Number of groups: 4
Trials per group: 4
Answer: Option (a) is the correct answer.
Explanation:
When these two conducting spheres are connected together through a thin wire then charge from the smaller sphere will travel through the wire. And, this charge will continue to travel towards the neutral sphere until the charge on both the spheres will become equal to each other.
For example, charge on small sphere is 5 C then this charge will continue to travel towards the neutral sphere until its charge also becomes equal to 5 C.
Hence, then their potential will also become equal.
Thus, we can conclude that the spheres are connected by a long, thin wire, then after a sufficiently long time the two spheres are at the same potential.
