The Answer is true, the saying opposites attract are true for magnets when poles match though they repel.
If the 30 N on the rope were pulled straight up, it would offset the force of gravity ( m g = 10 kg * 9.8 N/kg = 98 N) , leaving a net force up from the ground on the sled of 98-30 = 68 N. Since the rope is pulled at the angle of 25o, only part of the force is in the upward direction, (30N)(sin(25) = (30)(.423) = 12.7. So the net force becomes 98 N down offset by 12.7 up or 98-12.7 = 85.3 N. Ah, there it is: C.

Explanation:
Convection is a type of process where heat travels upwards and cold travels downwards.
Answer:
Not possible.
Explanation:
Exoplanets are an active area of modern research. The article states that the outermost planet (Planet C) goes all the way around its star in less time than the innermost planet (Planet A). Which is not possible as it will violet Kepler's third law of planetary motion. Which says that the square of orbital period of a planet is proportional to the cube of its semi-major axis of its orbit.
