What is supernova?A supernova is the enormous, dazzling explosion of a star. Supernovae or supernovas are the plural forms of its abbreviation, SN or SNe. This brief astronomical event occurs either in the latter stages of the formation of a large star or when a white dwarf is set off into uncontrolled nuclear fusion. The original object, referred to as the progenitor, either falls into a neutron star or a black hole, or entirely disintegrates. Before fading over the course of several weeks or months, the optical luminosity of a supernova can reach a peak that is similar to the luminosity of an entire galaxy. The latest supernova in the Milky Way to be directly observed was Kepler's Supernova in 1604, however more recent supernova remnants have been found.

A car traveling on a straight road at 10 meters per second accelerates uniformly to a speed of 21.0 meters per second in 12.0 seconds. The total distance traveled by the car in this 12.0-second time interval is?
Answer:
185.3m
Explanation:
Given parameters:
Initial velocity = 10m/s
Final velocity = 21m/s
Time = 12s
Unknown:
Total distance traveled by the car = ?
Solution:
To solve this problem, we use that appropriate motion equation:
v² = u² + 2as
v is the final velocity
u is the initial velocity
a is the acceleration
s is the unknown distance
t is the time taken;
acceleration = [tex]\frac{v - u}{t}[/tex]
a = [tex]\frac{21 - 10}{12}[/tex] = 0.92m/s²
now;
v² = u² + 2as
21² = 10² + 2(0.92)(s)
441 = 100 + 1.84s
441 - 100 = 1.84s
s = 185.3m

The fundamental frequency of the tube is 0.240 m long, by taking air temperature to be [tex]37^o[/tex]C is 367.42 Hz.
A standing wave is basically a superposition of two waves propagating opposite to each other having equal amplitude. This is the propagation in a tube.
The fundamental frequency in the tube is given by
[tex]f=\frac{v_T}{4L}[/tex]
where, [tex]v_T=v\sqrt{\frac{T}{273} }[/tex]
Since, T=37+273 K = 310 K
v = 331 m/s
[tex]\therefore v_T=331\sqrt{\frac{310}{273} } = 352.72 \ m/s[/tex]
Using this, we get:

Which statement accurately describes the charge of the nucleus of an atom? (2 points)
O a The nucleus can be either positively charged or neutral.
Ob
The nucleus never has an electrical charge.
O c
The nucleus always has a positive charge.
Od
The charge of a nucleus can change from positive to negative.
The nucleus of an atom will have a positive charge due to the existence of protons, which are positively charged subatomic particles.
Protons and neutrons are present in an atom's nucleus. We are aware that a proton has a charge of + 1 and a neutron has a charge of 0 (or no charge). As a result, the atom's nucleus will always be positively charged. A nucleus is a name for the dense area in the middle of an atom. Because there are positively charged subatomic particles present, the nucleus usually has a positive charge. The subatomic particles, which are present in atoms but far smaller than atoms, are there. Protons, neutrons, and electrons are the three primary subatomic particles found in matter. An atom's nucleus contains protons and neutrons, while its outermost nucleus contains electrons. Neutrons are subatomic particles with a charge of zero, whereas protons are positively charged.
Therefore, the nucleus of an atom will always have a positive charge. Consequently, an atom's nucleus has a positive charge because of the presence of protons.

What does this tell you about the direction and magnitude of the acceleration acting on the cannonball throughout its duration of flight?
Answer:
Direction remains the same but velocity changes.
Explanation:
This tell us about the direction and magnitude of the acceleration acting on the cannonball throughout its duration of flight that its direction remains the same but its magnitude of the acceleration is continuously changing. The cannonball moves in the direction in which the cannon was fired while the velocity is highest after the fire but decreases when goes higher and when it comes back to the ground so its velocity increases against so we can say that both positive and negative acceleration occurs. Positive acceleration means increase in the magnitude of velocity whereas negative acceleration means decrease in velocity.
In the year 2000, a company made $4.7 million in profit. For each consecutive year after that, their profit increased by 15%. How much would the company's profit be in the year 2004, to the nearest tenth of a million dollars?
Answer: $8.2 million.
Explanation:
If we have a quantity A, and we have an increase of x%, this can be written as:
A + (x%/100%)*A
Now, for this particular case we have:
In year 2000 (we can define this year as the year zero, y = 0) the initial value is $4.7 million.
The next year, y = 1, there is an increase of 15%, then we will have a profit of:
P = $4.7 million + (15%/100%)*$4.7 million = $4.7 million + 0.15*$4.7 million
P = $4.7 million*(1 + 0.15) = $4.7 million*(1.15)
in the next year, y = 2, the profit will be:
P = $4.7 million*(1.15) + (15%/100%)* $4.7 million*(1.15)
= $4.7 million*(1.15) + 0.15* $4.7 million*(1.15)
= $4.7 million*(1.15)^2
We already can see the pattern, the profit in the year y will be:
P(y) = $4.7 million*(1.15)^y
In particular, in the year 2004 we have y = 4, then the profit that year will be:
P(4) = $4.7 million*(1.15)^4 = $8.2 million.
What is the relationship between magnetism and the movement of electrical charges in generators ( the device).
Answer:
Electricity and magnetism are two related phenomena produced by the electromagnetic force. Together, they form electromagnetism. A moving electric charge generates a magnetic field. A magnetic field induces electric charge movement, producing an electric current.
Explanation:
A wire carrying a current I is bent into the shape of an equilateral triangle of side L. (a) Find the magnitude of the magnetic field at the center of the triangle.
The magnetic field at the center of the triangle is [tex]\frac{4.50 \mu_{0} I}{\pi L}[/tex].
An equilateral triangle with side L is formed by the bend of a wire carrying a current I.
The magnetic field created by a straight wire is given as:
[tex]B = \frac{ \mu_{0} I}{2 \pi a}[/tex]
The cosines of the complementary angles are identical to the sines of the angles that appear in that equation.
The magnetic field from a distance "a" from the wire,
We obtain:
[tex]tan{~}30^{\circ} = \frac{a}{L/2}\\a = 0.2887L[/tex]
Therefore, the magnetic field at P which is the center of the triangle will be:
[tex]B = \frac{\mu_{0} I}{4 \pi a}(cos{~}\theta_{1} - cos{~}\theta_{2})[/tex]
[tex]B = \frac{\mu_{0} I}{4 \pi \times 0.2887L}(cos{~}30^{\circ} - cos{~}150^{\circ})[/tex]
[tex]B = \frac{\mu_{0} I \times 1.732}{\pi \times L}[/tex]
[tex]B = \frac{1.50 \mu_{0} I}{ \pi L}[/tex]
Every side produces the same amount of field in the same direction, which in the illustration is perpendicular to the paper.
Therefore, the total field is:
[tex]\frac{1.50 \mu_{0} I}{ \pi L} = \frac{4.50 \mu_{0} I}{ \pi L}[/tex]

What is the force of gravity acting on a 2000 kg spacecraft when it is about the Earth at a in orbit distance of 8.375 x 106 m?
Answer:
W = 13.44 KN
Explanation:
First, we need to find the value of acceleration due to gravity at the specified height:
[tex]g' = g(1-2\frac{h}{R})[/tex]
where,
g' = value of acceleration due to gravity at given height = ?
g = value of acceleration due to gravity at surface of earth = 9.81 m/s²
h = height of space craft = 8.375 x 10⁶ m - 6.37 x 10⁶ m = 2.005 x 10⁶ m
R = Radius of Earth = 6.37 x 10⁶ m
Therefore,
[tex]g' = (9.81\ m/s^2)(1-2\frac{2.005\ x\ 10^6\ m}{6.37\ x\ 10^6\ m})\\\\g' = (9.81\ m/s^2)(1 - 0.315)\\g' = 6.72\ m/s^2[/tex]
Now, we can find the weight or force of gravity on space craft:
[tex]W = mg'[/tex]
where,
W = Force of gravity on space craft = ?
m = mass of space craft = 2000 kg
Therefore,
[tex]W = (2000 kg)(6.72\ m/s^2)[/tex]
