Given: Mass m = 0.61 Kg; Displacement x = 4.0 cm or x = 0.04 m
Required: Spring constant k = ?
Formula: F = kx
k = F/x
k = (0.61 Kg)(9.8 m/s²)/0.04 m
k = 149.45 N/m
Answer:
Potential
Explanation:
This is because it has not yet fallen, and it has the potential to fall and turn into kinetic energy. When it starts falling, it will be kinetic.
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center SO THE ANSWER IS “NEAR EITHER POLE•
Answer:
Explanation:
mass of charged particle m = 6 x 10⁻³ kg .
speed of particle v = 4 x 10³ m /s
speed of particle perpendicular to magnetic field = v sin37
= 4 x 10³ sin37
= 2.41 x 10³ m / s
Force on charged particle
= B q v , B is magnetic field , q is charge on particle and v is velocity perpendicular to B
Force = ma
= 6 x 10⁻³ x 8
= 48 x 10⁻³
Force = Bqv
48 x 10⁻³ = 5 x 10⁻³ q x 2.41 x 10³
q = 48 x 10⁻³ / (5 x 2.41)
= 3.98 x 10⁻³C.
PE = mass * height * 9.81
PE = 142 * 25 * 9.81
PE = 34825.5 J
