Answer:
Take north as y and west as -x.
distance=√(x^2+y^2)
displacement= tan theta(tan^-1) (y/x)
answers should be, (9.85m, 66.04°)
Answer:
(a)-0.701m
(b)-0.674m/s
Explanation:
Given a = -0.24,m/s² Xo = 0.170m, u = 0.190m/s
X = Xo + ut +1/2at²
X = 0.170 + 0.190×3.6 + 1/2×(-0.24) 3.6² = -0.701m
(b) its velocity at the end of this time interval is v
v = u + at
= 0.190 + (-0.24)× 3.6 = -0.674m/s
An electromagnet is made from a coil of wire which acts as amagnet when an electric current passes through it. Often anelectromagnet is wrapped around a core of ferromagnetic material like steel, which enhances the magnetic field produced by the coil.
