Answer:
Explanation:
It says “Momentum before the collision is equal to momentum after the collision.” Elastic Collision formula is applied to calculate the mass or velocity of the elastic bodies.
Answer:
so in a given orbital there can be 3 electrons.
Explanation:
The Pauli exclusion principle states that all the quantum numbers of an electron cannot be equal, if the spatial part of the wave function is the same, the spin part of the wave function determines how many electrons fit in each orbital.
In the case of having two values, two electrons change. In the case of three allowed values, one electron fits for each value, so in a given orbital there can be 3 electrons.
C. element only one substance
Answer:
Energy gained by the second particle = 12Uo
Explanation:
Given Data;
Resistant force = 12F
Initial kinetic energy = Uo
Calculating the kinetic energy gained, we have;
u = f *r
where f= resistant force = 20F
r = initial kinetic energy = Uo
Therefore,
U = 12 * uo
= 12 Uo
Therefore, energy gained by the second particle = 12Uo
Answer:
x = 108.5 m y = 45.37 m,
Explanation:
This is a projectile launching exercise, the horizontal distance it reaches is called the range and can be found by the expression
x = v₀ₓ t
the initial hairiness is
v₀ₓ = v₀ cos θ
x = v₀ cos θ t
let's calculate
x = 53 cos 35 2.50
x = 108.5 m
the height of the projectile can be calculated with
y =v₀ t - ½ g t²
y = vo sin tea t - ½ g t²
y = 53 sin 35 2.50 - ½ 9.8 2.5²
y = 45.37 m
