Answer:
neutron is a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
0.14 (rounded to the nearest hundreth)(full answer: 0.13544323097)
(a) could possibly become a vector
First, we need to find the spring constant
Force of gravity = force of tension from spring
mg = kx
(1x10^-3)(9.8) = k (3.2x10^-2)
k = .30625
Now we can look at the other situation
Since the spring was moved 0.01 meters, we can find the force
F = kx = (.01)(.30625) = .0030625 N
Now we can set the electric force equal to the force of the beads
kq^2/r^2 = .0030625 N
q = 292 microCoulombs
Answer:
θ = 45º
Explanation:
To find the solution, let's use the projectile launch equation
R = vo² sin 2θ / g
Where vo is the initial speed of the dolphin, T is the angle of the jump and g the gravity acceleration.
To obtain a maximum range, the sine T function must be 1,
sin 2θ = 1
2θ = sin⁻¹ 1
2θ = 90
θ = 45º
Therefore, the dolphin should jump at an angle of 45º from the horizontal
