Aparticle with charge − 5.20 nc is moving in a uniform magnetic field b⃗ =−( 1.24 t )k^. the magnetic force on the particle is measured to be f⃗ =−( 4.00×10−7 n )i^+( 7.60×10−7 n )j^. a calculate the x-component of the velocity of the particle.

b calculate the y-component of the velocity of the particle.

c calculate the scalar product v⋅f

d what is the angle between v and f ? give your answer in degrees.

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
