Why is the nucleus of an atom dense​
Inessa [10]

Explanation:

The nucleus of an atom is dense because it contains more of particles in a very little space.

The nucleus is the center of an atom made up of the protons and neutrons.

Atomic nucleus is very small compared to the size of the atom.

 Density is function of mass and volume.

Mass is the amount of matter in a substance.

Volume is the space occupied by a substance.

    The more the mass the more the density.

Since protons and neutron are massive bodies occupying a small space, they make the nucleus very dense.

An object travels with velocity v = 4.0 meters/second and it makes an angle of 60.0° with the positive direction of the y-axis.
zhenek [66]

Answer:

2 m/s and -2 m/s

Explanation:

The object travels with an angle of

60.0°

with the positive direction of the y-axis: this means that it lies either in the 1st quadrant (positive x) or in the 2nd quadrant (negative x).

If it lies in the 1st quadrant, the value of vx (component of v along x direction) is:

v_x = v cos \theta = (4.0 m/s) cos 60.0^{\circ}=2 m/s

If it lies in the 2nd quadrant, the value of vx (component of v along x direction) is:

v_x = -v cos \theta = -(4.0 m/s) cos 60.0^{\circ}=-2 m/s
