A scientist discovers a new body between the orbit of Neptune and the Kuiper Belt. The object is round and travels in an orbit around Neptune with other space objects. The scientist claims that she has found a new dwarf planet. Where is the scientist’s error?

The object is an asteroid, not a dwarf planet.
The object is a moon, not a dwarf planet.
The object is not a dwarf planet because it travels with other objects.
The object is not a dwarf planet because it is round.

the answer is c i did the same question so i know that's right!

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
