Answer:
The ball has kinetic energy
the kinetic energy is 945 J
Explanation:
Answer:
The electric force between A and B will increase.
Explanation:
The Earth's radius is 6371 km. So that's our distance from the center when we're on the surface.
The Shuttle astronaut's distance from the center, when s/he's in orbit, is 330 km greater ... that's 6701 km.
The force of gravity is inversely proportional to the distance between the center of the Earth and the center of the astronaut. So, in orbit, it's
(6371/6701)^2 = 90.4 %
of its value on the surface.
They would identify the frogs by looking at their DNA and the genetic material
Answer:
false
Explanation:
Resultant is a force with the combined effect of two or more forces. Even though a force is a vector, it is not part of the definition of a vector. Vectors a made of 2 or more components, depending on the dimension of the vector. A 2-D vector has two components, 3-D has three, and so on. In your case, you are probably generally working on 2-D vectors, so simply two components would be correct.
