ad two vectors?
A. Torque, energy, magnetic flux
B. Electric flux, momentum, force
C. Mass, Magnetic field strength, pressure
D. Momentum, moment of a force, gravitational potential
gradient

equation P Q RS . Given that the equation is
homogeneous, then which of the following statements must
be correct?
A. P, Q, R and S have the same units
B. P, Q, R and S are all scalar quantities
C. The product RS has the same units as P and Q

4) A satellite is in a highly elliptical orbit around the Earth.
Which of the following statements is a direct
consequence of Kepler’s Second Law regarding the
satellite’s motion?
A. The satellite’s angular velocity is constant throughout its
orbit
B. The satellite’s potential energy is constant throughout its
orbit
C. The satellite spends a longer time in the portion of its
orbit farthest from the Earth than in the portion closest
to the Earth
D. The satellite’s kinetic energy is constant throughout its
orbit.
5)A beam of monoenergetic alpha particles is incident on a
thin gold foil. It is observed that a small fraction of the
alpha particles are deflected through large angles. Which
of the following statements provide the most complete
explanation for this phenomenon?
A. Alpha particles are scattered by the electrons in the gold
atoms.
B. Alpha particles are repelled by the positively charged
nuclei of the gold atoms
C. Most of the atom is empty space, allowing most alpha
particles to pass through undeflected, but a small
number encounter the concentrated positive charge of
the nucleus.
D. The wavelength of the alpha particles causes diffraction
effects, leading to scattering
6) The spatial distribution of the electric field due to charges
(A and B) is shown in the figure 1 below.
Which one of the following statements is correct?
A. A is positive and B is negative; |𝐴| > |𝐵|
