If the mass and post-collision speed of block 1 is known, the momentum of the block 2 can be determined.
<h3>
What is momentum?</h3>
The momentum of an object in motion is the product of mass and speed of the object.
P = mv
<h3>Conservation of linear momentum</h3>
The principle of conservation of linear momentum states that, the sum of the initial momentum must be equal to the sum of the final momentum.
Thus, if the mass and post-collision speed of block 1 is known, the momentum of the block 2 can be determined.

Answer:
The ion has more protons than electrons.
Explanation:
Explanation:
Effective nuclear charge is defined as he net positive charge experienced by an electron in an atom. It is termed "effective" because the shielding effect of electrons prevents higher orbital electrons from experiencing the full nuclear charge of the nucleus due to the repelling effect of inner-layer electrons.
The 1s is the closest shell to the nucleus of an therefore maximum nuclear charge is experienced. The formula for effective nuclear charge is:
Zeff = Z – S
where
Z = the number of protons in the nucleus, and
S = the shielding constant, the average number of electrons between the nucleus and the electron.
Hence, the energy required to remove an electron from the 1s orbital is the strongest.
Change in temperature
A calorimeter directly measures temperature change and this information, along with the substance's mass and specific heat, is used to calculate the amount of heat.<span />
Answer:
W = 1.44 10⁻⁷ J
Explanation:
The expression for the job is
W = ∫ F. dx
Where the point is the scalar product in this case the direction of the meteor and the depth is parallel, whereby the scalar product is reduced to the ordinary product
W = 630 ∫ x³ dx
W = 630 x⁴ / 4
Let's evaluate between the lower limit x = 0, w = 0 to the upper limite the point at x = 5.5 10⁻³ m
W = 157.5 ((5.5 10⁻³)⁴ -0)
W = 1.44 10⁻⁷ J
