I don’t think I will have any time to go
Answer:
the answer is gravitational force hope this helps u stay safe
Explanation:
Answer:
attached below is the free body diagram of the missing illustration
Initial kinetic energy of the electron = 3 eV
Explanation:
The conclusion that can be drawn about the kinetic energy of the electron is
E
= initial kinetic energy of the electron
E
= -4 eV
E
= -1 eV
insert the values into the equation above
= -1 -(-4) eV
= -1 + 4 = 3 eV
I believe it’s 8.3 to be precise
Answer:
0.281 m
Explanation:
Applying,
W = 0.5ke².................. Equation 1
Where W = Workdone by the stretched spring, k = spring constant, e = extension/ compression of the spring
make e the subject of the equation
e = √(2W/k)................ Equation 2
From the question,
Given: W = 1.240J, k = 31.50 N/m
Substitute these values into equation 2
e = √(2×1.240/31.50)
e = √(0.07873)
e = 0.281 m
