If an elephant has a net force of 10000 N downward while experiencing an upward force of 9000 N from air resistance, what is the

elephant's gravitational force downward?
-1000 N, downward
-20000 N, downward
-19000 N, downward
-0 N, the forces are balanced

QveST [7]
Compton scattering equation of wavelengths 
λ'-λ = h/mec (1 - CosФ)
λ' = λ + h/mec (1 - cos 180°)
= ( 0.0830nm) + (6.626 × 10⁻³⁴ J.s)/ (9.1 × 10⁻³¹ kg)(3.0 × 10⁸ m/s
= 0.0830nm
The momentum of electron is
P photon λ = Pe + P phpton λ'
Pe = h/λ - ( -h/λ') = h(λ' + λ)/λλ'
= (6.626 × 10⁻³⁴ J.s)(( 0.08785nm) +( 0.0883nm)/0.08785nm)( 0.083nm)
1.55 × 10⁻²³ kg.m/s.

What is the atomic number of an Neon atom with 10 protons and 11 neutrons in its nucleus, & 10 Electrons in orbitals around
vesna_86 [32]

Answer:

10

Explanation:

The atomic number is only based on the number of the elements protons.  The neutrons and electrons will only change the atomic mass and properties of the element.  So the atomic number is 10.

488 J of work is done to a box which is moved across the floor for a distance of 8.9 m. What net force is required to act on the
kvv77 [185]
According to the formula
a = f \times d
Where a is work, f is force and d is the distance that box was moved over. And from that formula, you can get that f = a/d and that is 54.83N of force

you push a coin across a table the coin stops how does this motion relate to balanced and unbalanced forces
-BARSIC- [3]
When you exert a force on the coin, it will accelerate. If you push the coin and it moves at a constant velocity, the friction force must be equal to the force that you are exerting. This is an example of a balanced force. When the net force is greater than 0 N, the is an unbalanced force.

If the kinetic energy of the 40kg box is 784 J, what is the velocity before it strikes the ground?
mamaluj [8]

Answer:

Explanation:

KE=\frac{1}{2}mv^2

784=\frac{1}{2}(40)v^2

784=20v^2

39.2=v^2

v=6.26m/s
