Average acceleration when the particle completes half revolution​ is 18 m/s^2.

If you whirl a ball on the string over your head, then the ball is undergoing centripetal acceleration. If you drive a car around in circle, then your car is undergoing centripetal acceleration.

The average acceleration of a particle moving in a circular path is given by the formula: a = v^2/r, where v is the velocity of the particle and r is the radius of the circular path.

For the given particle, the velocity is 6 m/s and the radius is 2m. Therefore, the average acceleration is given by a = v^2/r = 6^2/2 = 18 m/s^2.

There are also reasons not to, but usually it keeps you on the road.

Explanation:

If I keep my vehicle straight behind the one in front of me, as long as they are fine I’m fine.
Although, if they make a mistake it’s easy to be too focused on following them than to save yourself.

Using the taillights of the vehicle in front of you to guide you in snowy conditions can help improve your visibility, provide guidance on the road ahead, and keep you centered and safe while driving in challenging conditions.

In extremely snowy conditions, visibility can be severely reduced, making it difficult to see the road ahead and navigate safely. Using the taillights of the vehicle in front of you can help guide you for several reasons:

(1) Contrast: The taillights of a vehicle provide a contrasting light against the white background of the snow, making it easier to see and follow the vehicle in front of you.

(2) Visibility: The taillights are usually positioned higher up on the vehicle than the brake lights, making them more visible above the snow drifts or other obstacles on the road.

(3) Indicators: The taillights provide indicators of the vehicle in front's movements, such as when they are turning or slowing down. By paying attention to these indicators, you can anticipate the actions of the vehicle ahead and react accordingly.

(4) Centering: Following the taillights of the vehicle in front can help keep you centered on the road and prevent you from accidentally veering off course.

The velocity of a Simple Harmonic Oscillator is half of its maximum velocity at a distance of 0.50A from x-O.

A Simple Harmonic Oscillator is a physical system that undergoes periodic motion, such as a mass attached to a spring. The motion of a simple harmonic oscillator can be described by the equation of motion:

x = A * cos(ωt),

where x is the displacement from the equilibrium position, A is the amplitude of the motion, ω is the angular frequency, and t is time.

The velocity of a Simple Harmonic Oscillator can be derived from the displacement equation:

v = dx/dt = -A * ω * sin(ωt).

The maximum velocity of a Simple Harmonic Oscillator occurs when the displacement is at its maximum value, which is at x = A. At this point, the velocity is equal to -A * ω * sin(ωt) = -A * ω. The velocity is half of its maximum value when sin(ωt) = 0.5, which occurs when t = π / (2ω). At this time, the displacement is x = A * cos(π / (2ω)) = A * √(0.5), or approximately 0.50A from x-O.

The (x, y) coordinate where the shell exploded is (9861.56 m, 58041.32 m).

The horizontal and vertical displacement of the shell can be calculated using the following equations:

x = Vx * t

y = Vy * t - 0.5 * g * t^2

where

Vx = 300 m/s * cos(55) = 234.38 m/s (horizontal velocity)

Vy = 300 m/s * sin(55) = 224.14 m/s (vertical velocity)

g = 9.8 m/s^2 (acceleration due to gravity)

t = 42 s (time elapsed)

Plugging in the values we get:

x = 234.38 m/s * 42 s = 9861.56 m

y = 224.14 m/s * 42 s - 0.5 * 9.8 m/s^2 * 42^2 s^2 = 66946.16 m - 8904.84 m = 58041.32 m

Answer:

2.4 m/s

Explanation:

The formula for speed is s = d/t

We have the distance and time so plug those numbers in

623/4.22   We can't divide the number like this so...

Convert the 4.22 into seconds >>>  240 + 22 = 262

Now we can divide the numbers.

The distance to each object using a baseline of 1000km is a)10313250 km b)31416000 km c)10313250000 km.

Parallax shift is the apparent shift of an object's position due to a change in the observer's point of view. In astronomical terms, it's used to measure the distance to nearby stars. The formula to calculate the distance (d) of an object using its parallax (p) and the baseline (b) is:

d = (1 / p) * (b / 2)

where p is expressed in radians. To convert from degrees (°), minutes (') or seconds (") to radians, we use the following conversions:

1° = (π / 180) rad

1' = (1° / 60) = (π / 10800) rad

1" = (1' / 60) = (π / 648000) rad

So for (a), 1° parallax:

d = (1 / (π / 180)) * (1000 / 2) km = (180 / π) * (1000 / 2) km = (180 / π) * 500 km = 206265 * 500 km = 10313250 km

For (b), 1' parallax:

d = (1 / (π / 10800)) * (1000 / 2) km = (10800 / π) * (1000 / 2) km = (10800 / π) * 500 km = 62832 * 500 km = 31416000 km

For (c), 1" parallax:

d = (1 / (π / 648000)) * (1000 / 2) km = (648000 / π) * (1000 / 2) km = (648000 / π) * 500 km = 206265000 * 500 km = 10313250000 km

So in each case, the distances are approximately 10313250 km for 1° of parallax, 31416000 km for 1' of parallax, and 10313250000 km for 1" of parallax, as measured from a 1000-km baseline.

The pressure in a 0.5 m^3 vessel charged with 10 kg of carbon dioxide at 30°C can be calculated using the ideal gas law.

The ideal gas law states that the pressure (P), volume (V), number of moles (n), and temperature (T) of an ideal gas are related by the equation PV = nRT, where R is the gas constant. To calculate the pressure in the vessel, we need to know the number of moles of carbon dioxide, the volume of the vessel, and the temperature.

First, we can convert the mass of carbon dioxide (10 kg) to moles using its molar mass (44 g/mol):

n = 10 kg / (44 g/mol) = 0.227 moles

Next, we can calculate the pressure in the vessel using the ideal gas law:

P = (nRT) / V = (0.227 moles * 8.31 J/(mol*K) * (303 K)) / (0.5 m^3) =~ 59.3 atm
