Momentum is the result of a particle's mass and velocity. A vector quantity with both magnitude and direction is momentum. Isaac Newton's second equation of motion states that the force applied to a particle is equivalent to the time rate of change of momentum.
Any grouping of particles has a momentum equal to the vector sum of their momenta. A modification in one particle's momentum is perfectly balanced by a modification in the momentum of another particle, according to Newton's third law, which states that particles exert equal and opposite forces on one another.

Initial discovery of radioactivity and how it was thought to be the same as another type of light energy emission is true statement.
Henri Becquerel made the initial discovery of radioactivity. She investigated the characteristics of x-rays, which Wilhelm Roentgen had discovered in 1895, using naturally fluorescent minerals. In the belief that the uranium would absorb the sun's energy and then release it as x-rays, he placed potassium uranyl sulphate on photographic plates covered in black paper and exposed them to the sun.A study released earlier this month by the Global Carbon Project (GCP), a team of scientists who monitor emissions, predicts that CO2 emissions will increase by 4 point 9 percent in 2021 compared to the previous year.
Due to the COVID-19 pandemic and related lockdowns, emissions decreased by 5 point 4 percent in 2020.

1. Predict the change in capacitance of a parallel plate capacitor as the area of the plates is increased.
2. Predict the change in capacitance of a parallel plate capacitor as the separation between the plates is increased.
3. Briefly describe the observations you will make in Activity 1-2 of the lab to test one of these two predictions.
4. If you have two identical capacitors, what do you predict will be the capacitance of the two connected in parallel?
5. Briefly describe the observations you will make in Activity 2-1 of the lab to test this prediction.
6. What devices will you use to measure the decay of voltage in an RC circuit?
A parallel plate capacitor has a capacitance of C=fracepsilon_0 Ad, where A is the area of the plates and d is the distance between them. 1) If the area of the plates A_1 grows, then A_1>A C_1=fracepsilon_0 A_1d>fracepsilon_0 Ad C_1>C, which means that the capacitance also grows.
2) If the distance between the plates is increased by d_1, the capacitance decreases because d_1>d C_1=fracepsilon_0 Ad_1 fracepsilon_0 Ad C_1C.
3) Since capacitance is directly proportional to plate area, capacitance also increases with plate area.
Because capacitance is inversely proportional to plate separation, capacitance decreases as plate separation increases.
4) When two identical capacitors are connected in parallel, their equivalent capacitance is C_1 C_1=C+C=2C. 6) The Voltmeter is the device used to measure the voltage decay in an RC circuit.

how is einstein's famous equation, e = mc2, important in understanding the sun?
The correct answer is option D) the Sun generates energy to shine by losing 4 million tonnes of mass each second.
What is sun ?
The Sun, a 4.5 billion year old yellow dwarf star and the centre of our solar system, is a hot, glowing ball of hydrogen and helium. It's about 93 million miles (150 million kilometers) from Earth and it's our solar system's only star. The sun is not a solid mass. It does not have easily identifiable boundaries like rocky planets like Earth. Instead, the sun is composed of layers made up almost entirely of hydrogen and helium.
It explains the fact that the Sun generates energy to shine by losing some 4 million tonnes of mass each second. The "lost" 4 million tonnes is turned to an amount of energy equal to this mass times the speed of light squared.In order to produce the energy we see it produce, the Sun needs to fuse 4 × 1038 protons into helium-4 per second. The upshot of that fusion is that 596 million tonnes of helium-4 are formed with each second that passes, while 4 million tonnes of mass are turned into pure energy via E = mc2.

The block's acceleration is 3.585 m/s^2, while the cord tension is 17.4 N. depicts two blocks attached by a cord (of minimal mass) that crosses a frictionless pulley.
A block weighs 1.30 kg per m1.
A 2 m2 block weighs 2.8 kg.
Block-block system acceleration = a
T is equal to the cord's tension.
The acceleration of block 1 in our coordinate systems is equal to the acceleration of block 2 in our coordinate systems. So, using a common acceleration, we can express them. These are the motion equations:
T = m1*g - m1*a and M2*g - T
We obtain the equation of motion for the entire system by combining the two equations.
(m1+m2)
*a = m2*g-m1*g
The acceleration is given by the equation a = (m2-m1)*g/(m1+m2), a = (2.8-1.3)9.8/(1.3+2.8), and a = 3.585 m/s2.
