a car starts from rest on a curve with a radius of 130 m and tangential acceleration of 1.3 m/s2 . Through what angle will the car have traveled when the magnitude of its total acceleration is 2.6 m/s2?
The car will have traveled through an angle of approximately 119.7 degrees when the magnitude of its total acceleration is 2.6 m/s^2.
What is the angle of approximate calculation?
The magnitude of the total acceleration of a car on a curved path can be given by:
a = √(at^2 + ac^2)
where at is the tangential acceleration (1.3 m/s^2), and ac is the centripetal acceleration, which is given by:
ac = v^2 / r
where v is the velocity of the car and r is the radius of the curve (130 m).
Setting a = 2.6 m/s^2, we can solve for v:
v = √(r * a^2 - at^2) = √(130 * 2.6^2 - 1.3^2) = 27.47 m/s
The angle through which the car will have traveled can be found using the equation for the arc length s:
s = r * θ
where θ is the angle in radians. Substituting the values for v and t into the equation for s, we can solve for θ:
θ = s / r = v * t / r
Since the car started from rest, t can be found from the equation for acceleration:
at = v / t
t = v / at = 27.47 / 1.3 = 21.06 s
Finally, substituting t into the equation for θ, we get:
θ = v * t / r = 27.47 * 21.06 / 130 = 2.07 radians = 119.7 degrees

What is the walking ghost phase of radiation?
The "walking ghost phase" of radiation is a term that refers to a short period of time after exposure to a high dose of ionizing radiation, during which the individual may appear to be unaffected by the exposure.
The term originated during the Manhattan Project, when scientists observed that individuals who had received a high dose of radiation would often feel relatively normal for a short period of time before experiencing severe symptoms. During the walking ghost phase, the individual may experience few or no symptoms of radiation exposure, even though their body is sustaining significant damage from the radiation. This is because the initial effects of radiation exposure are often delayed, and the damage to the body's cells and tissues takes time to manifest as symptoms. After the walking ghost phase, the individual may begin to experience symptoms such as nausea, vomiting, diarrhea, fever, and weakness. The severity and duration of these symptoms depend on the dose of radiation and other factors such as the individual's age, health, and medical treatment. It is important to note that the walking ghost phase is a term used primarily in historical contexts, as modern radiation exposure scenarios generally do not involve such high doses of radiation that would produce this effect. Nonetheless, it serves as a reminder of the dangers of ionizing radiation and the importance of taking measures to minimize exposure.

Why is titanium non-magnetic?
Titanium is a non-magnetic metal because of its digital configuration and crystal shape.
In its pure shape, titanium has a hexagonal near-packed (hcp) crystal structure, this means that that its atoms are organized in a specific pattern in the crystal lattice.
This association outcomes inside the absence of unpaired electrons that could create magnetic moments, making it non-magnetic. Moreover, the electron configuration of titanium does not permit for magnetic moments to shape.
Titanium has four valence electrons, which are positioned within the 3-d and 4s orbitals.
The electrons in the 3d orbital are paired, which means that they've opposite spins and cancel out any magnetic second that could be created by means of the electrons inside the 4s orbital.
But, whilst titanium is alloyed with other metals, inclusive of iron or nickel, it may turn out to be magnetic because of the magnetic houses of these metals.

What is the capacitors ?A capacitor is an electrical component that consists of two conductive plates separated by an insulating material known as a dielectric. The capacitor stores electrical energy in the form of an electrostatic field between the two plates. When a potential difference is applied between the plates, it creates an electric field which can store energy.
The output of the oscillator (the collector voltage) is fed back to the base of the transistor via the capacitive divider. As the collector voltage increases, the voltage across the two capacitors increases, which increases the base current of the transistor, further increasing the collector voltage and thus providing positive feedback.

A ball is launched horizontally off a platform at 15 m/s. The ball takes 1 second to
hit the ground. The height of the platform is
m. The ball will
land
m. from the base of the platform.
Answer:
Below
Explanation:
The ball has one second to fall from its height and to travel horizontally at 15 m/s
Rate X Time = distance 15 m/s * 1 s = 15 meters from the platform .
df = do + vot + 1/2 a t^2
df = final position = o ft ( on the ground)
do = initial position = height
vo = original vertical velocity = 0
a = - 9.81 ms^2
so you have this:
0 = height + 1/2 (- 9.81) m/s^2 * (1)^2
height = 4.9 meters

What determines colloid osmotic pressure?
Colloid osmotic pressure is determined by protein concentration gradient across blood vessel walls.
Colloid osmotic strain (COP) is a sort of osmotic tension not set in stone by the centralization of proteins in an answer. These proteins, regularly egg whites and globulin, are too huge to even consider going through the walls of veins, and thus, they stay in the plasma (the fluid piece of blood) and make a fixation slope across the vein walls. This fixation slope prompts a net development of water into the veins, which assists with keeping up with blood volume and forestall liquid collection in the tissues.
The COP of an answer is relative to the convergence of proteins in the arrangement, with higher centralizations of protein bringing about higher COP. COP is significant in various physiological cycles, including the guideline of circulatory strain, the support of liquid equilibrium, and the anticipation of edema (expanding brought about by liquid gathering in the tissues).

When an electron beam is aimed at two closely spaced slits, the electrons passing through the slits will interfere with each other, producing an interference pattern on a screen behind the slits. The interference pattern will be a series of bright and dark bands, where the bright bands correspond to constructive interference and the dark bands correspond to destructive interference.
When a beam of electrons is passed through two closely spaced slits, it creates an interference pattern on a screen behind the slits. This pattern results from the wave-like behavior of electrons and the interference between the electrons passing through the two slits. The pattern appears as a series of bright and dark bands, where the position and intensity of the bands are determined by the relative phase of the electrons.

why do higher temperatures often result in greater precipitation
The higher temperatures often result in greater precipitation because warm air holds more water vapor.
A warmer planet means more precipitation will fall in regions of the world where water vapor is the factor that is currently limiting the amount of precipitation that occurs. This is the condition across a significant portion of the middle and upper latitudes across the Earth.
To put it simply, the amount of precipitation that falls is increasing as temperatures rise because warm air can carry more water vapor.

Energy consumption per second is measured as power. The amount of force necessary to create a unit displacement is another way to quantify power. Power, a scalar quantity, is represented by the letter P. For instance, a light bulb with 100 W of electricity will provide more light than one with 10 W.
The power in a circuit is measured using electrical power, which is given in watts. Electrical and mechanical-electrical techniques are used to measure electrical power in centrifugal pump applications. A watt, which represents power, is equivalent to one joule every second.
Power = Work done /Time taken
Time = 2 minutes = 120 seconds.
Work = 720kJ = 720000J
Power = 720000/120 = 6000W
P = 6kW
