Answer: The package appears to fall straight downward
Explanation:
When the package is dropped from the plane (which has constant speed) it will follow a parabolic path. Then, as the plane and the package have the same constant speed in the horizontal component (X component of the movement) and a constant vertical acceleration due gravity, from the plane the package will always be seen below it, falling straight downward (free fall).
This is possible if it is assumed that there are no additional horizontal forces such as air resistance, thus fulfilling Newton's 1st Law of inertia that estates if a body is in equilibrium the sum of all the forces acting on it is equal to zero.
Answer:
the electric field is 42.8×10^6 N/C
Explanation:
let k be the coulomb constant, Q be the charge distribution , R be the radius of the disk and x be the distance from the center.
k = 8.98755×10^9 N×m^2/c^2
Q = 6.1×10^-6 C
R = 4.9×10^-2 m
x = 3.1×10^-3 m
Answer:
you need to multiply the momentum and the mass
A Framework for K–12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (Framework) recommends science education in grades K–12 be built around three major dimensions: science and engineering practices, crosscutting concepts that unify the study of science and engineering through their common application across fields, and core ideas in the major disciplines of natural science.
