m/s/s
Answers
Hey,
QUESTION )Following the second Newton's Law :
✔ We apply : F = m x a ⇔ m = F/a with F in N, m in kg and a in m/s²
m = 20/2,5 m = 8 kgthe object therefore has a mass of 8 kg

What is electromagnetic spectrum ?The electromagnetic spectrum encompasses electromagnetic waves with frequencies ranging from less than one hertz to greater than 1025 hertz, corresponding to wavelengths ranging from thousands of kilometres to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are given different names; beginning at the low-frequency (long-wavelength) end of the spectrum, these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

What do supernova have to do with heavy elements?
Answers
Answer:
When a star dies, it is called a supernova. A supernova contains massive amounts of energy, and the hydrogen and helium that was originally in the star turns into heavier elements ranging from oxygen to iron to gold.

Answer:
Read Below
Explanation:
During the supernova nucleosynthesis, the r-process creates heavy isotopes, which decay after the event to the first stable isotope, thereby creating the neutron-rich stable isotopes of all heavy elements. The neutron capture occurs in high neutron density with high-temperature conditions.

Answers
Answer: The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if the distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.

8. As you throw a 2.00 x 102 g baseball, your hand moves a distance of 80.0 cm before you release the ball. If you exert an average force of 55.0 N on the ball while it is in your hand, determine:
Answers
Answer:
v = 21.0 m / s
Explanation:
In this exercise, it is generally asked to determine the final speed of the ball.
Let's start by finding the acceleration of it
F = ma
a = F / m
let's reduce the magnitudes to the SI system
m = 2.00 102 g (1kg / 1000g) = 0.200 kg
x = 80.0 cm (1m / 100 cm) = 0.800 m
we calculate
a = 55.0 / 0.200
a = 275 m / s
now we can use kinematics, where the ball has an initial velocity of zero and travels a distance x = 80 cm with the force
v² = v₀² + 2 a x
v² = 0 + 2ax
v = [tex]\sqrt{2ax}[/tex]
let's calculate
v = [tex]\sqrt{2 \ 275 \ 0.800}[/tex]Ra 2 275 0.800
v = 20.98 m / s
if we use the criteria of significant figures
v = 21.0 m / s

(Choice A)
There is a net force on the coin.
(Choice B)
There are no forces on the coin.
(Choice C)
There is no net force on the coin.
(Choice D)
There is not enough information.
Answers
A coin falls off a table and is traveling to the ground. There is a net force on the coin which is responsible for the motion of the coin. Thus, the correct option is A.
What is Net force?The net force can be defined as is the sum of all the forces which are acting on an object. Net force acting upon an object can accelerate its mass. Some other forces also acts on a body either at rest or motion. The net force is used in a system when there is a significant number of forces acting on the object.
A coin which falls off a table and is still traveling to the ground. Then, it can be concluded that there is a net force which is acting on that coin which is responsible for the motion of the coin.
Therefore, the correct option is A.
