The particle accelerator at CERN in Geneva, Switzerland, has a circumference of 27
. Inside it protons are accelerated to a speed of 0.999999972
What is the circumference of the accelerator in the frame of reference of the protons?

Answer:

10km/h describe its velocity

Explanation:

Velocity =distance /time

It defined as the rate of change of the object's position with respect to a frame of reference and time.

If you travel a distance of 10 Km in 1 hour then 10 km/h is your velocity.

Velocity can be explained as a vector measurement of the direction and rate of motion of an object. The velocity of an object can be specified as the rate of change in the object’s position w.r.t. time.

Velocity can be defined as a vector parameter as it consists of both magnitude and direction. The velocity can be determined from the formula mentioned below:

v = d / t

where v is the velocity, d represents the distance covered, and t is the time.

Although the S.I. unit for the measurement of velocity is m/s or, miles per hour (mph), and kilometers per hour (kph).

Given, the distance traveled, d = 10  km

The time is taken, t = 1 hr

The velocity, v = d/t = 10 km/1 h = 10 km/h

This question can be solved by using equations of motion.

A. The grapefruit dropped by "3.1 m".

B. The speed of the grapefruit, when it hit the ground was "7.8 m/s".

A.

We will use the second equation of motion here to find out the distance dropped by the grapefruit:

\(h = v_it+\frac{1}{2}gt^2\)

where,

h = height dropped = ?

vi = initial speed = 0 m/s

t = time period = 0.8 s

g = acceleration due to gravity = 9.81 m/s²

Therefore,

\(h = (0\ m/s)(0.8\ s)+\frac{1}{2}(9.81\ m/s^2)(0.8\ s)^2\)

h = 3.1 m

B.

Now, we will use the first equation of motion to find out the final speed:

\(v_f = v_i +gt\)

vf = 0 m/s + (9.81 m/s²)(0.8 s)

vf = 7.8 m/s

Answer:

10.3 m/s to the east

Explanation:

Use the law of conservation of linear momentum:

m1Vi1 + m2Vi2 = m1Vf1 + m2Vf2

We know that

m1 = 7 kg. Vi1 = +5.0 m/s (east is +) Vf1 = -2.0 m/s

m2 = 3.0 kg. Vi2 = -6.0 m/s (west is -) Vf2 = ?

or

(7)(5) + (3)(-6) = (7)(-2) + 3Vf2

Solving for Vf2, we get

Vf2 = 10.3 m/s (to the east)

A) To find F_1, the volume of fluid flowing into the pipe per unit of time (volumetric flow rate), we can use the formula:

B) To solve for v_2, v_2 = (A_1 * v_1) / A_2.

C) If you are shown a picture of streamlines in a flowing fluid, you can conclude that the "velocity" of the fluid is greater where the streamlines are closer together.

Part A
To find F_1, the volume of fluid flowing into the pipe per unit of time (volumetric flow rate), we can use the formula:
F_1 = A_1 * v_1

Here, A_1 is the cross-sectional area of the pipe at its entrance and v_1 is the speed of the fluid as it enters the pipe.

Part B
To find the velocity v_2 of the fluid flowing out of the right end of the pipe, we can use the continuity equation, which states that the volumetric flow rate is constant throughout the pipe:
A_1 * v_1 = A_2 * v_2

To solve for v_2, we can rearrange the equation:
v_2 = (A_1 * v_1) / A_2

Part C

The speed at which a particle's relativistic momentum equal twice its classical momentum, will be 2.598* 10^8 m/s.

Relativistic momentum ensures that the conservation of momentum holds in all inertial frames.

The relativistic effects of length contraction, time dilation, and other similar phenomena are experienced by particles when they move at very high speeds (near the speed of light). The mass of the particles also varies at this high speed. The relativistic momentum is the product of the particle's velocity and its corresponding relativistic mass.

(a) The magnitude of the displacement of the cyclist in the 39.0 s interval is 50.0 m. (b) The direction of the displacement is 26.6° counterclockwise from due east. (c) The magnitude of the average velocity is 1.29 m/s (d) The direction of the average velocity is 90° counterclockwise from due east. (e) The magnitude of the average acceleration is 0 m/s². (f) The direction of the average acceleration is undefined.

(a) The magnitude of the displacement of the cyclist in the 39.0 s interval is 50.0 m.

To calculate the displacement, we need to find the net change in position of the cyclist. From the given information, in the first leg of the journey, the cyclist moves 36.0 m due south. In the second leg, the cyclist moves 36.0 m due north. The net change in the north-south direction is 36.0 m - (-36.0 m) = 72.0 m. Since the displacement is the shortest straight-line path between the initial and final positions, the magnitude of the displacement is given by the Pythagorean theorem: √((72.0 m)^2 + (36.0 m)^2) = 50.0 m.

(b) The direction of the displacement is 26.6° counterclockwise from due east.

To determine the direction, we can use trigonometry. The angle can be found using the inverse tangent function: θ = tan^(-1)((36.0 m) / (72.0 m)) = 26.6°. Since the cyclist is north of the flagpole, the displacement is counterclockwise from due east.

(c) The magnitude of the average velocity is 1.29 m/s.

Average velocity is calculated as the displacement divided by the time interval: (50.0 m) / (39.0 s) = 1.28 m/s.

(d) The direction of the average velocity is 90° counterclockwise from due east.

Since the cyclist is moving east during the second leg of the journey, the average velocity is in the same direction. Counterclockwise from due east is 90°.

(e) The magnitude of the average acceleration is 0 m/s².

Average acceleration is given by the change in velocity divided by the time interval. Since the speed of the cyclist remains constant at 12.0 m/s throughout the journey, there is no change in velocity, and thus the average acceleration is 0 m/s².

(f) The direction of the average acceleration is undefined.

Since the average acceleration is 0 m/s², there is no change in velocity, and therefore, no specific direction can be assigned to the average acceleration.

If thermal energy is added to 150 g of water at a rate of 55 J/s for 2.5 minutes, the temperature of the water will increase by 6.58°C, as calculated using the equation for specific heat capacity.

To determine the increase in temperature of 150 g of water when thermal energy is added at a rate of 55 J/s for 2.5 minutes, we need to calculate the amount of heat energy added to the water and use this to determine the increase in temperature.

The amount of heat energy added to the water can be calculated as follows:

Q = 55 J/s * 2.5 min * 60 s/min = 6675 J

Next, we can use the equation for specific heat capacity to determine the increase in temperature of the water:

ΔT = Q / (mass * specific heat capacity)

where ΔT is the increase in temperature, Q is the heat energy added, mass is the mass of water (150 g), and specific heat capacity is the amount of heat energy required to raise the temperature of 1 g of water by 1°C (usually around 4.18 J/g°C).

Substituting in the values, we have:

ΔT = 6675 J / (150 g * 4.18 J/g°C) = 6.58°C

So the temperature of the water would increase by 6.58°C.

When 1.0-a electric current flows through a piece of cylindrical copper wire, the voltage drop is 5.38 mv, so the electric resistance of the wire is 5.38 ohms.

The electric resistance of the wire can be calculated using Ohm's Law, which states that the voltage drop across a conductor is equal to the product of the current flowing through it and the resistance of the conductor. Mathematically, this can be written as:

V = I * R

Where V is the voltage drop, I is the current, and R is the resistance. We can rearrange this equation to solve for the resistance:

R = V / I
