An increase in the atmospheric concentrations of greenhouse gases produces a positive climate forcing, or warming effect. From 1990 to 2015, the total warming effect from greenhouse gases added by humans to the Earth’s atmosphere increased by 37 percent. The warming effect associated with carbon dioxide alone increased by 30 percent.

Answer:

Climate change mitigation consists of actions to limit the magnitude or rate of global warming and its related effects. An increase in the atmospheric concentrations of greenhouse gases produces a positive climate forcing, or warming effect. From 1990 to 2015, the total warming effect from greenhouse gases added by humans to the Earth's atmosphere increased by 37 percent

A 1.25 kg block is attached to a spring with spring constant 17.0 N/m . While the block is sitting at rest, a student hits it wi

Free_Kalibri [48]

Answer:

The amplitude of the subsequent oscillations is 13.3 cm

Explanation:

Given;

mass of the block, m = 1.25 kg

spring constant, k = 17 N/m

speed of the block, v = 49 cm/s = 0.49 m/s

To determine the amplitude of the oscillation.

Apply the principle of conservation of energy;

maximum kinetic energy of the stone when hit = maximum potential energy of spring when displaced

$K.E_{max} = U_{max}\\\\\frac{1}{2} mv^2 = \frac{1}{2} kA^2\\\\where;\\\\A \ is \ the \ maximum \ displacement = amplitude \\\\mv^2 = kA^2\\\\A^2 = \frac{mv^2}{k} \\\\A = \sqrt{\frac{mv^2}{k}} \\\\A = \sqrt{\frac{1.25\ \times \ 0.49^2}{17}} \\\\A = 0.133 \ m\\\\A = 13.3 \ cm$

Therefore, the amplitude of the subsequent oscillations is 13.3 cm

There are 92 naturally occurring elements. How does this relate to the number of compounds?

raketka [301]

C) Elements combine in different ways to create many more than 92 compounds.

Explanation:

The number of elements we have relates to the compound formation in that, elements combine in different ways to create many more than 92.

Elements are distinct substances that cannot be split up into simpler substances. Such substances are only made up of one kind of atom.

Compounds are substances that are made up of two or more kinds of atoms joined together in a definite grouping.

Several millions of compounds are known because elements can combine in different ways.
The number of elements do not increase because new elements are discovered, it is because elements have several ways by they combine.

A gold nucleus is 466 fm (1 fm = 10-15 m) from a proton, which initially is at rest. When the proton is released, it speeds away

Artist 52 [7]

Answer:

$v=6.8\times10^6m/s$

Explanation:

The sum of the kinetic and electric potential energies of the proton when initially released must be equal to their sum at infinity, so we have:

$K_i+U_i=K_f+U_f$

Which, since $K_i=0J$ because initially the proton is at rest, is:

$\frac{kqQ}{d}=\frac{mv^2}{2}+\frac{kqQ}{r_\infty}$

where $k=9\times10^9Nm^2/C^2$ is Coulomb's constant, $q=1.6\times10^{-19}C$ the charge of the proton, $Q=(79)(1.6\times10^{-19})C$ the charge of the gold nucleus, since it has 79 protons, $d=466\times10^{-15}m$ the initial separation between them, $m=1.67\times10^{-27}kg$ the mass of the proton and v its final velocity. $r_\infty$ is very far away, so the final electric potential will be 0J, and we have:
