They will go off in opposite directions with the same force.

What is Newton's third law?

Newton's third law states that if object A exerts a force on object B, then object B must apply a force to object A that is equal in magnitude and directed in the opposite direction. This law illustrates a symmetry in nature whereby forces always occur in pairs and whereby no body can exert a force without also being subjected to one.

Newton's Third Law states that for every action, there is an equal but opposite reaction. If two people are standing on a scooter and push off each other (following the Law), it should come to the conclusion that they could go off in opposite with the same force.

By using the blackbody radiation formula, the temperature of the filament inside the bulb is changed by a factor of 10⁰'²⁵.

We need to know about black body radiation to solve this problem. The energy radiated by a black body object is proportional to the area and the fourth power of temperature. It can be determined as

P = A . e . σ . T⁴

where P is power, A is surface area, e is emissivity, σ is Stefan Boltzmann's constant ( 5.67 x 10¯⁸ W/m²K⁴) and T is temperature.

From the question above, we know that

P1 = 10 watt

P2 = 100 watt

T1 = T1

By using the black body radiation formula, the ratio of temperature is

T1⁴ / T2⁴ = P1 / P2

Hence,

T1⁴ / T2⁴ = P1 / P2

T1⁴ / T2⁴ = 10 / 100

T1⁴ / T2⁴ = 1 / 10

T2⁴ = 10T1⁴

T2 = ⁴√(10T1⁴)

T2 = T1 x 10⁰'²⁵

Thus, the temperature of the filament inside the bulb is changed by a factor of 10⁰'²⁵.

The residue of f(z) = πzcot(πz) can be calculated using series expansion. To calculate the residue of f(z), we can expand the function f(z) in a Laurent series around the singularity (pole) of the function.

The function f(z) = πzcot(πz) has a pole of order 1 at z = 0. To expand the function in a Laurent series, we can write cot(πz) as its Taylor series expansion and then multiply it by πz. The Laurent series expansion of f(z) around the singularity z = 0 is:

f(z) = πzcot(πz) = πz(1/πz + (πz/3) + (π^3z^3/45) + ...)

Simplifying this expression, we get:

f(z) = 1 + (\(π^2z^2^/^3\)) + ((\(π^4z^4^/^5)\) ) + ...

The residue of f(z) can be obtained by extracting the coefficient of the term with 1/z. In this case, the residue is 1.

Therefore, the residue of f(z) = πzcot(πz) is 1.

We can find the angular velocity at t = 2.0 s by plugging in this value into the equation.

\(\omega (t) = 25.0t \\\\\omega (2) = 25.0(2) = \boxed{50.0 \frac{rad}{s}}\)

b)

The angular acceleration is the derivative of the angular velocity, so:
\(\alpha (t) = \frac{d\omega}{dt} (25.0t) = 25.0\)

Thus, the angular acceleration is a constant 25 rad/s².

The correct answer is b. 0.20 Hz.

To find the frequency, we need to know how many cycles (in this case, pacing back and forth) occur in a unit of time (in this case, one second).

We know that the coach paces back and forth 10 times in 2 minutes. To convert minutes to seconds, we can multiply by 60:

10 times 2 minutes = 20 cycles in 120 seconds

To find the frequency, we divide the number of cycles by the time:

20 cycles / 120 seconds = 0.1667 cycles per second

To convert cycles per second to hertz (Hz), we simply use the same value:

0.1667 Hz ≈ 0.20 Hz

Therefore, the frequency of the coach's pacing is approximately 0.20 Hz.

The dog covered 28 m of distance, magnitude of displacement is 4m and direction is in east.

Distance is a scalar quantity that describes how much ground an object covers while moving, and displacement is a vector quantity that describes how far an object has travelled. This is the global change in the object's position.

We know that total distance travelled = 12 m + 16 m = 28 m.

First the dog walks 12m west, but then walks back 16m east. That means you have to subtract the distances to get the displacement.

Displacement = 12 - 16 = -4m (4m to the east, because the distance can never be negative)

Part A:

We can use the principle of conservation of energy to determine the speed at which the quarterback throws the ball. Initially, the ball is at rest, so its initial kinetic energy is zero. The work done by the quarterback to accelerate the ball is given by the force applied times the distance over which it is applied. This work is equal to the final kinetic energy of the ball. Therefore, we have:

work done by the quarterback = 0.5mv^2

The force applied by the quarterback can be calculated using Newton's second law:

F = m*a

where a is the acceleration of the ball.

The acceleration of the ball can be determined using the distance over which the force is applied and the fact that the ball starts from rest:

a = (2*d)/t^2

where d is the distance over which the force is applied, and t is the time taken to apply the force.

Using the given values, we have:

d = 1.0 m

m = 0.42 kg

F = m*a

To find t, we need to first find the time of flight of the ball. The horizontal distance travelled by the ball is 70 m, which means that the time of flight is:

t_flight = d_horizontal / v_x

where v_x is the horizontal component of the velocity.

t_flight = 2*v_y / g

where v_y is the initial vertical velocity, and g is the acceleration due to gravity.

At the maximum height, the vertical velocity of the ball is zero, so we have:

v = sqrt(2*(F/m)d)

v = sqrt(2(F/0.42)1.0)

v = sqrt(4.76F)

F = mgcos(theta)

The thermal energy created by friction during Justin's descent down the water slide is approximately 332 J.

To determine the thermal energy created by friction during Justin's descent down the water slide, we can use the principle of conservation of energy.

The total mechanical energy of the system (Justin and the Earth) at the top of the slide is equal to the total mechanical energy at the bottom of the slide plus any energy lost due to friction.

At the top of the slide, Justin has potential energy (PE) due to his height above the ground, but no kinetic energy (KE) since he is at rest. At the bottom of the slide, he has no potential energy but has kinetic energy due to his speed:

\(PE(top) = mgh = (55 kg)(9.8 m/s^2)(8.0 m) = 4,292 J\)

KE(bottom) =

\((1/2)mv^2 = (1/2)(55 kg)(12 m/s)^2 = 3,960 J\)

The difference between the potential energy at the top and the kinetic energy at the bottom represents the energy lost due to friction:

The uterus lining is rebuilt by the end of the menstrual period. The rebuilding of the uterus lining starts after menstruation and the lining is typically completely rebuilt by day 14 of the menstrual cycle, which is when ovulation occurs and the uterus is preparing to potentially receive a fertilized egg.

The endometrium is the inner lining of the uterus, and it thickens every month to prepare for pregnancy. After menstruation, the endometrium grows and thickens to prepare for the implantation of a fertilized egg. The cells in the lining multiply and enlarge, and the glands in the lining begin to secrete mucus and other substances that help support the fertilized egg and promote its growth.

The rebuilding of the endometrium usually takes about two weeks after menstruation. This process is closely regulated by hormones such as estrogen and progesterone, which are produced by the ovaries and other parts of the body.

The ECG waveform that characterizes the conduction of an electrical impulse through the left ventricle is known as the QRS complex. The QRS complex represents the depolarization of the ventricles, specifically the rapid conduction of electrical activity through the bundle branches and Purkinje fibers, resulting in the contraction of the ventricular muscle.

The QRS complex consists of three main components:

Q wave: This is the first downward deflection after the P wave (atrial depolarization). It represents the initial depolarization of the interventricular septum.

R wave: This is the first upward deflection after the Q wave. It represents the depolarization of the main mass of the ventricles, particularly the left ventricle.

S wave: This is the downward deflection following the R wave. It represents the completion of ventricular depolarization.

The QRS complex appears as a series of three waveforms on an ECG (electrocardiogram): Q, R, and S. The Q wave represents the initial negative deflection, the R wave is the first positive deflection, and the S wave is the second negative deflection.

The QRS complex is typically broader and more prominent than other ECG waves, as the ventricular muscle has more mass and generates a larger electrical signal compared to the atrial muscle. The duration of the QRS complex is an important parameter to assess on an ECG, as abnormalities in its duration can indicate various cardiac conditions related to ventricular conduction abnormalities or ventricular hypertrophy.

Overall, the QRS complex reflects the electrical activity associated with the contraction of the left ventricle, which is the main pumping chamber responsible for delivering oxygenated blood to the body's systemic circulation.
