Answer:
Gravitational force interacts similarly with dark matter as it does with ordinary matter.
Electromagnetic force does not interact with dark matter since it does not emit, reflect or absorb light. However electromagnetic force interacts with ordinary matter since ordinary matter reflects, absorbs and emits light in varying spectrums.
Thus:
Ordinary matter only: Gravitational, Electromagnetic.
Dark matter only: Gravitational.
Dark matter and Ordinary matter: Gravitational.

Question 1 (1 point) What explanation does general relativity provide for gravity? A) Gravity can affect only massive particles, not massless photons B) Gravity is inversely proportion to the radius of the body. c) Gravity is directly proportional to the mass of the attracting body. D) Gravity is the opposite of the electromagnetic force. OE) Gravity is the result of curved spacetime. Question 2 (1 point) If light from a distant star passes close to a massive body, the light...

6. A playground merry-go-round, i.e., a horizontal disc of radius 3 m that can rotate about a vertical axis through its center, is rotating at an angular speed 1/s (measured, as usual, in terms of radians). The moment of inertia of the merry-go-round with respect to that axis is 3000 kg m? A student of mass 80 kg is standing at the center of the merry-go-round. The student now walks outward...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?

(a) Which part of an atom is positively charged, and which part is negatively charged? (b) How does the charge of an electron compare with the charge of another electron? (c) How does the charge of an electron compare with the charge of a proton? Can charge be created or destroyed? How does that answer relate to the conservation of charge? How is electric charge similar to mass? How are they different? What are two ways electric charge can be...

In Data 4.1 on page 258, we examine a study in which mice were randomly assigned to either a normal light/dark cycle or to have a light on around the clock. According to the paper describing that study, "The global increase in the prevalence of obesity and metabolic disorders coincides with the increase of exposure to light at night." The study is examining whether light at night plays a causal role in the obesity epidemic. In Data 4.1, we examine...
