Albert views henry moving by at a constant velocity. henry has a light clock and also a stopwatch which were synchronized when at rest. as albert views these two moving clocks, which of these statements would be true according to albert? the light clock runs slow compared to the stopwatch. the stopwatch runs slow compared to the light clock.
Answer:
The two are still synchronized but run slow
Explanation:
Time flows at a different rate for an object that is moving. The time of the object which is moving is running slower than an object which is stationary. Here, Albert is stationary so time will flow faster for him and for Henry who is moving time will flow slower. This phenomenon is called time dilation

What energy is calculated from an object's mass height and the acceleration due to gravity?
A beam of monochromatic light goes from material 1 with index of refraction n1 into material 2 with index of refraction n2. the frequency of light in material 1 is f1 and in material 2 is f2. what is the ratio of f1/f2?
To solve this problem, we should remember that the formula for index of refraction is defined as:
n = c / v
or
n v = c
Where,
n = index of refraction
c = speed of light
v = speed of light in the medium
Since speed of light is constant, then we can simply equate the materials 1 and 2:
n1 v1 = n2 v2
Where the speed of light in the medium (v) can be expressed as:
v = w * f
Where,
w = wavelength of light
f = frequency of light
Therefore substituting this back into the relating equation:
n1 w1 f1 = n1 w2 f1
Since it is given that the light is monochromatic, w1 = w2, this further simplifies the equation to:
n1 f1 = n2 f2
f1 / f2 = n2 / n1 (ANSWER)
The ratio of the frequency of light in two different materials can be found using their refractive indices and the equation n1*f1 = n2*f2.
The ratio of the frequency of light in two different materials is determined by their refractive indices.
In physics, the frequency of light can be related to the speed of light in different media using the index of refraction.
The equation n1*f1 = n2*f2 expresses the relationship between the frequencies of light in material 1 and material 2.
The ratio of frequencies f1/f2 of monochromatic light when moving from one material to another is 1, because the frequency of light remains constant across different media.
The student asks about the ratio of the frequencies f1 and f2 of monochromatic light going from one material with index of refraction n1 to another with index of refraction n2. This question pertains to the physics concept of refraction and properties of light as it travels through different media. The frequency of light does not change when it passes from one medium to another, as frequency is an intrinsic property of the wave that is independent of the medium. Therefore, the ratio of the frequencies f1/f2 is equal to 1, or f1=f2.

Imagine a landing craft approaching the surface of callisto, one of jupiter's moons. if the engine provides an upward force (thrust) of 3264 n, the craft descends at constant speed; if the engine provides only 2203 n, the craft accelerates downward at 0.39 m/s2. what is the weight of the landing craft in the vicinity of callisto's surface?
Final answer:
The weight of the landing craft on the surface of Callisto is 3264 N, derived by analyzing the force provided by the craft's engine in two different scenarios according to Newton's second law of motion.
Explanation:
The question involves understanding Newton's second law of motion, which is F = ma, where F is the net force applied to the object, m is the mass of the object, and a is the acceleration.
When the engine provides an upward force (thrust) of 3264 N, the craft descends at a constant speed, implying that the thrust balances out the weight of the craft (weight = gravitational force). Therefore, the net force, F, is zero, and the acceleration is 0 m/[tex]s^{2}[/tex]. When the thrust is only 2203 N, the craft accelerates downward at 0.39 m/[tex]s^{2}[/tex]. To find the weight of the landing craft on Callisto's surface, we can use the given data from the two scenarios.
To solve, let's denote the mass of the landing craft as m, and the acceleration due to gravity on Callisto as g. Thus, the weight of the landing craft, which is the gravitational force, can be expressed as W = mg.
From the second scenario, we have:
F - W = ma
2203 N - mg = m(0.39 m/[tex]s^{2}[/tex])
Since the first scenario tells us that F = W when F is 3264 N, substituting back, we get mg = 3264 N. We therefore find the weight of the landing craft to be 3264 N on the surface of Callisto.

If the energy bar was his only fuel, how far could a 68 kg person walk at 5 km/h?
To calculate how far a 68 kg person could walk at 5 km/h based on the energy from an energy bar, you need to know the energy content of the bar. Then, you would estimate the energy expenditure during walking and use that to estimate the distance that person could cover.
Explanation:Your question refers to energy and distance covered by a person walking at a certain speed, making it a topic of Physics. However, the computation of how far a 68 kg person can walk at 5 km/h, given a certain amount of energy (derived from an energy bar), requires more information.
We would specifically need to know the amount of energy provided by the energy bar. Once we have that, we can dive into understanding that energy consumption during physical activity, like walking, is determined by body mass and speed among other factors.
A common estimation of energy expenditure due to walking is made using the formula 0.1×weight(kg)×distance(km). After obtaining the energy content of the bar, we can rearrange that formula to find the distance: distance = energy/(0.1×weight). With that calculation, you could answer how far the person can walk based on the energy released by the bar.

Answer : (B) it decreased by 1/4
Explanation :
It is given that :
The distance between twin satellites that were originally 150 meters apart are now 300 meters apart.
When the satellites are 150 m apart then the gravitational force is :
[tex]F=G\dfrac{m_1m_2}{(150\ m) ^2}[/tex]..........(1)
Similarly, when the satellites are 300 m apart then the gravitational force is :
[tex]F'=G\dfrac{m_1m_2}{(300\ m) ^2}[/tex]...........(2)
From eq (1) and (2)
[tex]\dfrac{F_c}{F_c'}=4[/tex]
[tex]F_c'=\dfrac{F_c}{4}[/tex]
