Answer
given,
mass of glider = 0.23 Kg
spring constant = k = 4.50 N/m
spring stretched to 0.130 m
The springs potential energy =


U = 0.038 J
at x = 0,the only energy will be kinetic .


v² = 0.3304
v = 0.575 m/s
displacement of the glider
using conservation of energy



x = 0.678 m
neutrons
Explanation:
Isotopes of an element differ in their number of neutrons.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their nucleus.
- Isotopes of an element have the same electronic configuration.
- They have the same chemical properties but differ in their masses.
- The mass of an atom is function of the protons and neutrons.

The wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.
<h3>What is the speed of wave?</h3>
Speed of wave is the rate by which the wave travels. It can be described as the distance cover by the crest or thrust of it per unit of time. It can be calculated with the following formula,

Here, (f) is the frequency and (λ) is the wavelength.
The frequency is inverse of time. Thus, the value of frequency in time t is,

The speed of the wave is 0.5 m/s. Put the values in the formula,

Thus, the wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

Answer: Workdone293.02KJ
Explanation: The equation to use to calculate Workdone = Change in KE + Change in PE
Assuming velocity is constant,KE becomes 0
Workdone= Change in PE=mg
W=92×9.8×325=293.02KJ
