Answer:

7572 m/s

Explanation:

The force between two masses separated by a distance r is given as:

\(F=G\frac{m_1m_2}{r^2}\)

Where F is the attractive force between 2 masses, m1 and m2, r is the distance between the centres of the masses and G is the universal gravitation constant, which is \(6.674*10^-11 Nm^2/kg^2\)

The mass of the earth (\(m_1\)) is far greater than the mass of the sputnik (\(m_2\)). Therefore \(m_1m_2=m_1\). The mass of the sputnik is neglected, therefore:

\(F=G\frac{m_1}{r^2}=\frac{(6.674*10^{-11})(5.98*10^{24})}{(6.96*10^6)^2} = 8.2389N\)

But F is actually centripetal acceleration, a = v²/r

\(8.2389 = v^2 / 6.96*10^6\\v=7572m/s\)

The specific heat capacity of the liquid is 2.51 x 10³ J/kg⁰C.

The specific heat capacity of the liquid is calculated as follows;

Q = mcΔФ

The RMS value of the magnetic field (B) will also be doubled when the RMS value of the electric field (E) is doubled. The factor by which the magnetic field changes is 2.

To provide a detailed explanation, when the RMS value of the electric field in an electromagnetic wave is doubled, the RMS value of the magnetic field also changes. The relationship between the electric and magnetic fields in an electromagnetic wave is governed by Maxwell's equations. These equations state that the electric and magnetic fields are perpendicular to each other and vary in intensity in a synchronized way.

In an electromagnetic wave, the intensity of the electric field and the magnetic field are related by a constant known as the impedance of free space. This constant determines the strength of the magnetic field for a given strength of the electric field. Therefore, if the RMS value of the electric field is doubled, the RMS value of the magnetic field will also double. This means that the strength of both fields increases proportionally.

To solve this mathematically, we first need to understand the relationship between the electric field (E) and the magnetic field (B) in an electromagnetic wave. This relationship is given by the formula:

E = c * B

where E is the RMS value of the electric field, B is the RMS value of the magnetic field, and c is the speed of light in a vacuum.

Now, if the RMS value of the electric field (E) is doubled, we have:
2E = c * B'

where B' is the new RMS value of the magnetic field. We can now express B' in terms of the original magnetic field B:
2E = c * B'
2(c * B) = c * B'
2B = B'

Hence, the RMS value of the magnetic field (B) will also be doubled when the RMS value of the electric field (E) is doubled. The factor by which the magnetic field changes is 2.

Answer:

The magnitude will be "353.5 N". A further solution is given below.

Explanation:

The given values is:

F = 500 N

According to the question,

In ΔABC,

⇒ \(\angle BCA = (90-30)\)

⇒             \(=60^{\circ}\)

then,

⇒ \(\angle BAC=(180-45-60)\)

⇒             \(=75^{\circ}\)

Now,

The corresponding angle will be:

⇒ \(\angle FAC=60^{\circ}\)

⇒ \(\angle FAB=70+60\)

⇒             \(=135^{\circ}\)

Aspect of F across the AC arm will be:

= \(F\times cos(60)\)

On putting the values of F, we get

The resilience of a material is defined as the ratio of the energy stored in the material to the energy required to deform it. Mathematically, resilience is given by the equation.

Resilience = (Energy stored) / (Energy required to deform)

Given that the resilience of the protein resilin is 0.92, we can use this information to determine the energy required to stretch it, as well as the energy stored when it relaxes.

Let's denote the energy required to stretch the resilin as W and the energy stored when it relaxes as 6.00 J (given in the question).

Resilience = (Energy stored) / (Energy required to deform)

0.92 = 6.00 J / W

Solving for W, we can rearrange the equation as:

W = (Energy stored) / (Resilience)

W = 6.00 J / 0.92

Plugging in the given values, we can calculate the energy required to stretch the resilin:

W = 6.00 J / 0.92

W ≈ 6.52 J

So, the work done to stretch the resilin is approximately 6.52 J.

Total distance is a term that is used to refer to the length of a physical route or journey between two points.  The car will travel a total distance of 200 meters in 10 seconds.

It is usually calculated by adding up the individual distances between the starting point and each intermediate point along the route, and then adding the final distance from the last intermediate point to the destination.

Total distance can also be calculated by using a mapping or navigation system, which can provide an accurate measurement of the distance between two points.

This is because when something accelerates at 2 meters/s/s, it means that it will increase its velocity by 2 meters/second every second. Since the car starts from rest, it will have a velocity of 0 meters/second at the start.

Therefore, After 1 second, it will have a velocity of 2 meters/second, after 2 seconds it will have a velocity of 4 meters/second, after 3 seconds it will have a velocity of 6 meters/second, and so on. After 10 seconds, it will have a velocity of 20 meters/second.

0.840s is the half-life of lithium-8 if the decay constant is 0.825/s. The decay constant is unique to each radioactive substance and measures the speed of radioactive decay. Therefore, the correct answer is option D.

The half-life of lithium-8 can be calculated using the formula:

\(t1/2 = ln(2) / \lambda\)

Where t1/2 is the half-life, ln is the natural logarithm, and λ is the decay constant. Substituting the given decay constant of 0.825/s into the formula:

t1/2 = ln(2) / 0.825/s

t1/2 ≈ 0.840s

Therefore, the half-life of lithium-8 is approximately 0.840s. The formula for half-life is a fundamental concept in nuclear physics, which determines the time required for a radioactive substance to decay by half of its original quantity. The decay constant, which is specific to each radioactive substance, measures the rate at which radioactive decay occurs.

The higher the decay constant, the shorter the half-life, indicating that the substance is more unstable and decays faster. In this case, the decay constant of lithium-8 is 0.825/s, indicating that it is relatively unstable and has a short half-life of approximately 0.840s.

In summary, the half-life of lithium-8 is approximately 0.840s with a decay constant of 0.825/s. Therefore, the correct answer is option D.

Telescopes designed to study the earliest stages in galactic lives should be optimized for observations in infrared light. Infrared light has longer wavelengths than visible light, allowing it to penetrate dust and gas clouds more effectively.

This is particularly important for studying the earliest stages of galactic evolution, as these stages often involve dense regions of dust and gas that can obstruct visible light observations. By observing in the infrared spectrum, astronomers can detect the faint emissions from warm dust, molecular clouds, and newly forming stars that are otherwise hidden in the visible range. This enables them to study processes such as star formation, protoplanetary disks, and the evolution of galaxies in their early stages.Therefore, optimizing telescopes for observations in infrared light is crucial for gaining insights into the earliest stages of galactic lives and unraveling the mysteries of galactic evolution.

Answer:

The first choice: Mars travels at the highest speed at the closest approach to the sun.

Explanation:

Assume that the sun is stationary and that the gravitational pull from the sun is the only force on Mars.

The mechanical energy of Mars is the sum of two components:

Let \(r\) denote the distance between the sun and Mars. The \(\rm GPE\) between the two would be proportional to \((-1/r)\). Thus, increasing the distance between the sun and Mars would increase the \(\rm GPE\!\) of Mars in relation to the sun.

The kinetic energy \(\rm KE\) of Mars is proportional to the square of the speed of Mars. Increasing the speed of Mars would thus add to the \(\rm KE\!\) of this planet.

Since the gravitational pull from the sun is the only force on Mars, the mechanical energy of Mars would be conserved. In other words, the sum of the \(\rm KE\) of Mars and the \(\rm GPE\) of Mars in relation to the sun would be constant.

Thus, as the \(\rm GPE\) of Mars decrease (as the planet moves closer to the sun,) the \(\rm KE\) of Mars (and thus the speed of this planet) would necessarily increase.

The speed of Mars is maximized when the \(\rm KE\) of this planet is maximized. Because of the conservation of \(({\rm KE} + {\rm GPE})\), the \(\rm GPE\) of Mars in relation to the sun would need to be minimized. Thus, the distance between Mars and the sun at that moment would also need to be minimized. Hence, Mars would be travelling at the highest speed at its closest approach to the sun.
