Answer:
2 L, L, 2 L/3
Explanation:
For a pipe of length l open at both ends, the length of the pipe is given by :
or
For first pitch tone, n = 1
For first pitch tone, n = 2
For first pitch tone, n = 3
So, the wavelengths of the three lowest-pitch tones produced by this pipe are 2 L, L, 2 L/3 respectively. Hence, the correct option is (d)
this is due to the existence of other forces called the strong nuclear forces that overcomes the repulsion forces between the protons and keeps the nucleons holding to each other also there is a type of energy that is called the nuclear binding energy and this energy also works on binding the components of the nucleus together
C. is the answer. You can't use plastic because it does not conduct electricity and string does not conduct electricity either so the circuit will end before it get to the bulb.
7.11x 10⁶J
Explanation:
Given parameters:
Speed of light = 3 x 10⁸m/s
Mass of object = 23.7g = 0.0237kg
Unknown:
Energy = ?
Solution:
From Einstein's equation, we see that mass and energy are equivalent using the expression below:
E = mc²
Substituting the parameters:
E = 3 x 10⁸ x 0.0237 = 7.11x 10⁶J
