Which is greater 45 RPM or 4.71 rad/s? Why?
45 rpm is greater/faster. Convert both measurements to the same unit rate:
45 rpm = (45 rev) / (1 min) = (45 rev) / (60 s) = 0.75 rps
4.71 rad/s = (4.71 rad) / (1 s) • (1 rev) / (2π rad) = (4.71 rev) / (2π s) ≈ 0.74962 rps
what's the difference between work and power
Work is defined as the process of energy transfer to the motion of an object through the application of force. ... Power is defined as the amount of energy transferred in unit time. The SI unit of power is the watt.
You need to have power or energy, to be able to work. When you reach another lesson, you will learn about time, which is the flow of work you have done. You need more work than time for your work to count.

Which location, 23 degrees or 48 degrees would experience the same earthquake at stronger intensity?Explain why.
Answer:
48 degress
Explanation:
An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. In the United States, we use the Modified Mercalli Scale. Earthquake intensity is a ranking based on the observed effects of an earthquake in each particular place. Therefore, each earthquake produces a range of intensity values, ranging from highest in the epicenter area to zero at a distance from the epicenter.

The voltage across the terminals of a generator is 5.7 v when it supplies a current of 0.3 A. It becomes 5.1 V when I=0.9A. Find its emf and it's internal resistance
Answer:
The emf of the generator is 6VThe internal resistance of the generator is 1 ΩExplanation:
Given;
terminal voltage, V = 5.7 V, when the current, I = 0.3 A
terminal voltage, V = 5.1 V, when the current, I = 0.9 A
The emf of the generator is calculated as;
E = V + Ir
where;
E is the emf of the generator
r is the internal resistance
First case:
E = 5.7 + 0.3r -------- (1)
Second case:
E = 5.1 + 0.9r -------- (2)
Since the emf E, is constant in both equations, we will have the following;
5.1 + 0.9r = 5.7 + 0.3r
collect similar terms together;
0.9r - 0.3r = 5.7 - 5.1
0.6r = 0.6
r = 0.6/0.6
r = 1 Ω
Now, determine the emf of the generator;
E = V + Ir
E = 5.1 + 0.9x1
E = 5.1 + 0.9
E = 6 V
that is a difference between a law and a hypothesis?
A law describes how two variables affect each other, but a hypothesis only discusses one variable.
A law must be testable so that it can be proven, but a hypothesis is an untestable explanation.
A hypothesis includes an explanation for why two variables affect each other, but a law only describes how they
affect each other
A hypothesis may or may not be testable, but a law is an untestable explanation of why two variables affect each
other and cannot be proven
Answer:
A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon.
A law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. ... However, Newton's law doesn't explain what gravity is, or how it works.

A wave with a frequency of 325 Hz. is travelling at a speed of 125 m/s. What is the wavelength of this wave?
Answer:
0.385 meters
Explanation:
Just remember this very simple equation:
velocity=(wavelength)*(frequency)
I always remember it as "Velma is Waving Frantically"
So, 125=(wavelength)*(325)
Therefore, wavelength=0.385 meters!

describe the steps that occurs in the process of fission
Answer:
--In the first step, a uranium-235 atom absorbs a neutron, and splits into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy. -- In the second step, one of those neutrons is absorbed by an atom of uranium-238, and does not continue the reaction.
OR
Nuclear fission begins when a neutron hits the nucleus of an atom. The nucleus splits in two and releases thermal energy and releases more neutrons. The neutrons hits the nuclei of more atoms, splitting them and releasing more energy and neutrons.

3 Describe the two possible things that can happen if a charged object is brought near
another charged object,
4 Give one example of a balloon repelling another object, Explain why the balloon repelled
the object
Answer:
For two objects of charges q1 and q2, that are separated by a distance R, the force that each object suffers is given by the Coulomb's:
F = k*q1*q2/R^2
If both charges have the same sign, then we have a positive force, which means that the objects are "pushing" each other, then this is a repulsive force.
If instead, each object has a charge with a different sign, the force will be negative, then the objects will be pulling each other, and the force is an attractive force.
a) Whit this in mind, the two possible things that can happen if a charged object is near another charged object are:
The objects repel each other, which happens when both objects have charges with the same sign.
The objects attract each other, which happens when the objects have charges with a different sign.
b) A charged balloon most probably has a static charge (the type of charge that can be obtained by rubbing the balloon with a piece of cloth), which means that it has extra electrons, and we know that electrons have a negative charge, then we can assume that this balloon has a negative charge.
Then if we put another charged balloon (also with static charge) near our original balloon they will repel each other, this happens because both balloons have a negative charge.
How much work is required to raise a 0.75 kg flag from shoulder height (1.2m) To the top of the flag pole (4 m)?

If the radius of Earth were one half what it is now, and the mass were the same, what would be the value of g?
Answer:
4 times what it is now.
Explanation:
g=G(M/r^2)
G is constant, so ignore.
We have (1M/0.5r^2), or 4.
Answer:
4g
Explanation:
the equation of g (field gravity)
g = G M/R²
because G (Contant of Gravitasion) and M (Mass of earth) same, them
g2/g1 = R1²/R2²
g1 = g now
g2 = g which the value we looking for
g2/g = 1/(1/2)²
g2/g = 1/(1/4)
g2/g = 4
g2 = 4g

Consider a gate whose Shape is a parabolic arch of height 3m and base width 3m. If the origin of the coordinate system is at the vertex, then what is the equation of the edge of the gate?
Answer:
An arch in a memorial park, having a parabolic shape, has a height of 25 feet and a base width of 30 feet.
The equation of the parabolic arch with the height of 3m and base width of 3m is x²= 3/16 y.
What is parabolic equation?Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve. An essential component of a conic section is a parabola.
A parabola is formed by cutting a right circular cone in half along a plane perpendicular to the cone's generator. It is a locus of a moving point whose separation from the focus is equal to its separation from a stationary line (directrix) Focus refers to the fixed point, and directrix refers to the fixed line.
The equation of a parabola is x² = 4ay.
Height of the arch = 3 m
base width = 3 m
thus it goes through the point (3/2, 3)
then, (3/2)² = 4 a 3
a = 9 / (4× 12) = 3 /16
Then the equation of the parabolic arch becomes x² = 3/16 y.

3.1. A stone of mass 2kg is thrown vertically upward with a speed
of 20m's Calculate the maximum height reached.
Answer:
20.41 m
Explanation:
Let's list out the relevant variables in this problem. Take the upwards direction to be positive and the downwards to be negative.
v₀ = 20 m/sv = 0 m/sa = -9.8 m/s² Δy = ?We are using the fact that at maximum height, the object's velocity is 0 m/s right before it changes direction to fall vertically back down to Earth.
Find the constant acceleration equation that contains these four variables.
v² = v₀² + 2aΔySubstitute the known values into the equation and solve for Δy, the maximum height.
(0)² = (20)² + 2(-9.8)Δy 0 = 400 - 19.6Δy -400 = -19.6Δy Δy = 20.4081632653The maximum height of the stone is 20.41 m. Notice that its mass was irrelevant when solving for its maximum height when thrown.

It is chemically unreactive, it is highly radioactive and has a short half life.2) 7.5 times heavier than air and more than 100 times heavier than hydrogen. The gas liquefies at −61.8 °C (−79.2 °F) and freezes at −71 °C (−96 °F). On further cooling, solid radon glows with a soft yellow light that becomes orange-red at the temperature of liquid air (−195 °C [−319 °F]).Explanation:
