A vehicle, starting from rest, accelerates on a circular track with a 335m diameter. What is the distance travelled by the vehicle when it makes one complete cycle?

The answer is that the time the diver was in the air is 1.13 seconds.

To determine the time the diver was in the air, we can use the kinematic equation:

Δy = viΔt + 1/2at²,

where Δy is the displacement, vi is the initial velocity, a is the acceleration due to gravity (g), and t is the time.The initial velocity, vi, is given as 5.5 m/s, and since the diver jumps upwards, the displacement, Δy, is equal to the height of the board, which is 3.0 m. The acceleration due to gravity, a, is -9.8 m/s² (negative because it acts downwards).Substituting the known values into the equation:3.0

m = (5.5 m/s)t + 1/2(-9.8 m/s²)t²

Simplifying, we get:

4.9t² + 5.5t - 3.0 = 0

We can solve for t using the quadratic formula:

t = (-5.5 ± √(5.5² - 4(4.9)(-3.0))) / (2(4.9))= (-5.5 ± 1.59) / 9.8= -0.47 s or 1.13 s

Since time cannot be negative, the time the diver was in the air is 1.13 seconds.

The negatively charged sphere Z is most likely to leave the electric field near the center of plates, which is closest to letter Y.

Physical field that surrounds electrically charged particles and exerts force on all the other charged particles in the field is called an electric field.

Negatively charged sphere labeled Z will experience a force due to  electric field created by parallel plates. Since the vector is pointing right, we can assume that electric field is also pointing right.

Electric field lines are perpendicular to plates and are equally spaced. Therefore, electric field is uniform in magnitude and direction between the plates.

As the negatively charged sphere Z travels horizontally between plates, it will experience force in the direction opposite to electric field due to its negative charge. This force will cause sphere to slow down and  stop.

Since the electric field lines are equally spaced between the plates, electric field will be strongest at the edges of plates and weakest in the center. Therefore, negatively charged sphere Z is most likely to leave the electric field near the center of plates, which is closest to letter Y.

Answer:

You would weigh the same.

Explanation:

At the moment, since Earth is not a perfect sphere, the Earth "bulges out" at the equator, so you're further from the centre of the Earth. Since gravity acts through a body's center of mass, the further you are from the centre the weaker the gravitational acceleration you will feel, because gravity weakens over distance.

So, you're actually lighter at the equator than you'd be at the poles.

However, if the Earth was a perfect sphere, this "bulge" at the equator would not happen, and so you would weigh the same at the poles and at the equator.

Hope this makes sense.

The resistance of the longer wire assuming that the resistivity and the density of the material of the wire are unchanged during the drawing process is twice the resistance of the wire before, i.e. 16 Ω.

The impediment to current flow in an electrical circuit is measured by resistance. The ohm, a unit of measurement for resistance, is represented by the Greek letter omega. The name of the unit of resistance is derived from Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current, and resistance.

Given:

The resistance of the wire, R = 8 Ω.

Calculate the electrical resistivity by the formula given below,

σ = \(R\frac{A}{l}\),

Here σ is the electrical resistivity, A is the area, and l is the length of the wire.

According to Que's statement,

R₁ / R₂ = {σ₁ l₁ / A₁ } / {σ₂l₂ / A₂}

R₂ = 2 *R₁

R₂ = 2*8

R₂ = 16 Ω

Therefore, the resistance of the longer wire assuming that the resistivity and the density of the material of the wire are unchanged during the drawing process is twice the resistance of the wire before, i.e. 16 Ω.

\(v= 0.023\times 3.7\)

\(\large\boxed{\bold{v= 0.0851 \: m/s}}\)

Therefore, the speed of the given wave is 0.0851 m/s

To solve this problem, we can use the principle of conservation of energy. According to this principle, the total mechanical energy of an object remains constant as long as there are no external forces doing work on the object.

The initial mechanical energy of the girl and sledge is the potential energy they have due to their height above the ground. This potential energy is given by the formula:

PE = m * g * h

where PE is the potential energy, m is the mass, g is the acceleration due to gravity, and h is the height above some reference point.

The final mechanical energy of the girl and sledge is the sum of their kinetic energy and potential energy at the end of their motion.

We can set up the following equation to represent the conservation of energy:

Initial PE + Initial KE = Final KE + Final PE

Since the girl and sledge start from rest, their initial kinetic energy is zero. Therefore, the equation simplifies to:

Initial PE = Final KE + Final PE

We can determine the distance the girl and sledge travel down the slope by calculating the final kinetic energy and potential energy and solving for the distance.

The final kinetic energy is given by the formula:

KE = 1/2 * m * v^2

where KE is the kinetic energy, m is the mass, and v is the velocity.

The final potential energy is given by the formula:

PE = m * g * h

where PE is the potential energy, m is the mass, g is the acceleration due to gravity, and h is the height above some reference point.

To calculate the final kinetic energy, we need to determine the velocity of the girl and sledge at the end of their motion. We can use the principle of conservation of energy to solve for the velocity.

Substituting the given values into the equation for conservation of energy, we get:

Initial PE = Final KE + Final PE

= 1/2 * 40 kg * v^2 + 40 kg * 9.8 m/s^2 * h

We can solve for the velocity by rearranging the terms and substituting the values for the mass, initial potential energy, and final potential energy:

v = sqrt((2 * (Final PE - Initial PE)) / m)

= sqrt((2 * (40 kg * 9.8 m/s^2 * h - 40 kg * 9.8 m/s^2 * h)) / 40 kg)

= 0

Since the velocity is zero, the final kinetic energy is also zero. This means that the final mechanical energy is equal to the final potential energy, which is equal to the initial potential energy.

We can therefore set up the following equation to solve for the distance the girl and sledge travel down the slope:

Initial PE = Final KE + Final PE

= 0 + Final PE

= Initial PE

This equation tells us that the initial potential energy is equal to the final potential energy. Since the girl and sledge start from rest at the top of the slope and end at rest at the bottom of the slope, the final potential energy is equal to the initial potential energy.

Therefore, the distance the girl and sledge travel down the slope is equal to the distance they travel up the slope, which is 25m.

Answer:

required vertical distance below the edge is 0.6648 m

Explanation:

Given the data in the question;

Horizontal speed of water falls v = 2.73 m/s

direction of water falls 52.9° below the horizontal

The vertical velocity must be such that;

tanθ = v\(_y\) / v\(_x\)

Now, vertical speed of water falls;

v\(_y\) = v\(_x\) × tanθ

we substitute

v\(_y\) = 2.73 × tan(52.9°)

v\(_y\) = 2.73 × 1.322237

v\(_y\) = 3.6097

Now, at the top of falls, initial speed u = 0

v² - u² = 2as

s = ( v² - u² ) / 2as

we substitute

s = ( 0² - (3.6097)² ) / (2 × 9.8)

s = 13.029934 / 19.6

s = 0.6648 m

Therefore, required vertical distance below the edge is 0.6648 m

The maximum height the container can be lifted before bursting is  970 meters above sea level, and the maximum depth the container can be taken before imploding is 35 meters below the surface of the ocean.

Gauge pressure is the pressure measured relative to the atmospheric pressure at a particular location. It does not take into account the atmospheric pressure and only represents the pressure above or below the atmospheric pressure.

A) To find the maximum height h in meters above the ground that the container can be lifted before bursting, we need to find the new gauge pressure at this higher altitude. We can use the relationship between pressure and altitude:

P = P0 + ρgh

where P is the gauge pressure at the new altitude, ρ is the density of air, g is the acceleration due to gravity (assumed constant), and h is the height above sea level. Solving for h, we get:

h = (P - P0) / (ρg)

We know that the maximum pressure difference the container can withstand is ΔPmax = 2.35 × 105 Pa, so the new gauge pressure at the higher altitude can be found by adding this to the sea level pressure:

P = Pa + ΔPmax = 1.01 × 105 Pa + 2.35 × 105 Pa = 3.36 × 105 Pa

Substituting this into the equation above, along with the given values for ρ and g, we get:

h = (3.36 × 105 Pa - 2.02 × 105 Pa) / (1.20 kg/m3 × 9.81 m/s2) ≈ 970 meters

So, the maximum height the container can be lifted before bursting is approximately 970 meters above sea level.

B) To find the maximum depth dmax in meters below the surface of the ocean that the container can be taken before imploding, we need to find the new gauge pressure at this depth. We can use a similar equation to the one used above, but with the density of seawater instead of the density of air:

P = P0 + ρsgd

where g is the acceleration due to gravity (assumed constant), d is the depth below the surface of the ocean, and ρs is the density of seawater. Solving for d, we get:

d = (P - P0) / (ρsg)

We know that the maximum pressure difference the container can withstand is ΔPmax = 2.35 × 105 Pa, so the new gauge pressure at the maximum depth can be found by subtracting this from the sea level pressure:

P = P0 - ΔPmax = 2.02 × 105 Pa - 2.35 × 105 Pa = -0.33 × 105 Pa

(Note that this gives a negative value for pressure, which means the container will implode rather than burst.)

Substituting this into the equation above, along with the given values for ρs and g, we get:

d = (-0.33 × 105 Pa - 1.01 × 105 Pa) / (1025 kg/m3 × 9.81 m/s2) ≈ -35 meters

So, the maximum depth the container can be taken before imploding is approximately 35 meters below the surface of the ocean.

Therefore, The container can be lifted to a maximum height of 970 meters above sea level without bursting, and it can be submerged to a maximum depth of 35 meters without imploding.

Answer:

a) the amount of heat absorbed by the water is 431995.2 J

b) the amount of heat absorbed during evaporation is 2712000 J

Explanation:

Given that;

mass of water Mw = 1.2 kg

Specific heat capacity of water Cw = 4186 J/kg.C

Change in temperature ΔT = final T - Initial T = 100 - 14 = 86°C

Now

A)

Heat required to raise the temperature of water is expressed as:

Q = Mw × Cw × ΔT

Q = 1.2 × 4186  × 86

Q = 431995.2 J

Therefore the amount of heat absorbed by the water is 431995.2 J

B)

Then heat absorbed during evaporation will be:

Q1 = Heat absorbed during phase change from water to steam = Mw × Lv

Lv = latent heat of vaporization of water = 2.26 × 10⁶ J/kg

so

Q1 = 1.2 × 2.26 × 10⁶ = 2712000 J

Therefore the amount of heat absorbed during evaporation is 2712000 J

Answer:

You need the definition of acceleration (a=Vf-Vi/t) and 1 equation of linear motion (deltaX = Vi×t + 1/2×a×t^2). Since you know a is constant (gravity) and you know your initial Vi to be 40 m/s and your final velocity Vf to be zero (maximum height), then you can use thhe definition of acceleration to find time.

-9.81m/s^2 = (0-40m/s)/t

t = (-40)/(-9.81) s

t = 4.077s

Now that you have time, you should know all but deltaX in the equation of linear motion.

dX = (40m/s)(4.077s) + (1/2)(-9.81m/s^2)(4.077s)^2

dX = (163.099m) — (81.549m)

dX = 81.55m
