Explanation:
it says venus is often named as the earth's twin because both the planets share a similar size, surface composition and have an atmosphere with a complex weather system. But if you go in depth, the earth is just a little bit bigger than venus and both the planets move in opposite direction of eachother
The work done by the applied force = 650 J
Given the mass of the box = 40 kg
The displacement of the box on applying force = 5 m
Applied horizontal force = 130 N
The co-efficient of friction between box and floor is = 0.3
We have to find the work done by the applied force.
Work done by the applied force = Applied Force x Displacement of the box
= 130 N x 5 m
= 650 J
[Here the unit Nm is known as Joule(J) ]
We have the co-efficient of friction. So,
The force applied due to friction = Mass of the box x Co-efficient of friction x Acceleration due to gravity
= 40 kg x 0.3 x 9.8
= 117.6 N

Assuming north as positive direction, the initial and final velocities of the ball are:
(with negative sign since it is due south)
the time taken is
, so the average acceleration of the ball is given by
And the positive sign tells us the direction of the acceleration is north.
Answer:
Venus's very slow rotations rate does not allow a magnetic field to form
Answer:
s (l = 0) only two electrons
p (l = 1) sublevel six (6) electrons fit
d (l = 2) sub-level has 10 electrons
f (l = 3) has 7 has 14 electrons
Explanation:
The electrons have an odd spin, so they must comply with the Pauli principle, therefore only two electrons fit in a given sublevel.
Sub level s (l = 0) only two electrons
Sub level p (l = 1) has three orbitals in which two electrons fit, therefore in the sublevel six (6) electrons fit
Sub-level d (l = 2) has 5 orbitals each with two electrons, the sub-level has 10 electors
Sub-level f (l = 3) has 7 orbitals and two electrons each, the sub-level has 14 electrons
