How many cs are there in 40 mins plane ride?​

Answer:

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector. ... In its simplest form, average velocity is calculated by dividing change in position (Δr) by change in time (Δt).

Explanation:

The force of gravity is 103.73N and the parallel component of gravity is 40.45N along with the perpendicular component is 95.43N.

The gravitational force, which pulls mass-containing objects in the same direction, is the force of gravity. The force of gravity from Earth is something we consider frequently. Your body is held firmly in place by this force. However, every mass-bearing object pulls everything else with mass toward it through gravity.

The force of gravity F = ma

F = 4.51×23

F = 103.73N

F parallel component = F sinθ

F parallel = 103.73 sin 23°

F parallel = 103.73 × 0.390

F parallel = 40.45N

F perpendicular component =  F cosθ

F perpendicular = 103.73 × cos 23°

F perpendicular = 103.73 × 0.920

F perpendicular = 95.43N.

Sugar can cause health problems.

I believe that sugar should be regulated by the government since it causes heath problems. As according to this website heathline.com that up to one third of the population in America is obese. As well as that regulating sugar will greatly help lowering that number, seeing that many food products have tons of sugar in them. By lowering the sugar and regulating it can cause less obesity among the average person in the US. As stated by HeathlyFoodAmerca.org consuming too much sugar can cause increased heath problems as shown, heart disease, diabetes, and teeth decay and this is why I believe that the U.S government should regulate sugar more.

For a rectangular storage tank filled with paraffin to a depth of 2 m, the volume, weight, mass of paraffin, and pressure at the bottom of the tank are:

a. The volume is 24 m³.

b. weight is 240,000 N,

c. mass is 24,490 kg, and

d. pressure is 23,530 Pa.

a) The volume of paraffin in the rectangular storage tank can be calculated using the formula:

Volume = Length x Width x Depth

Given:

Length = 4 m

Width = 3 m

Depth = 2 m

Substituting the values into the formula, we have:

Volume = 4 m x 3 m x 2 m

Volume = 24 m³

Therefore, the volume of paraffin in the tank is 24 cubic meters.

b) The weight of the paraffin can be calculated using the formula:

Weight = Volume x Density x Acceleration due to gravity

The density of paraffin varies, but we can assume a typical value of 10,000 kg/m³. The acceleration due to gravity is approximately 9.8 m/s². Substituting these values into the formula:

Weight = 24 m³ x 10,000 kg/m³ x 9.8 m/s²

Weight = 240,000 N

Therefore, the weight of the paraffin in the tank is 240,000 Newtons.

c) The mass of the paraffin can be calculated using the formula:

Mass = Density x Volume

Substituting the given values:

Mass = 10,000 kg/m³ x 24 m³

Mass = 24,490 kg

Therefore, the mass of the paraffin in the tank is 24,490 kilograms.

d) The pressure at the bottom of the tank due to the paraffin can be calculated using the formula:

Pressure = Weight / Area

The area of the bottom of the tank is equal to the length multiplied by the width. Substituting the values:

Area = 4 m x 3 m

Area = 12 m²

Pressure = 240,000 N / 12 m²

Pressure = 20,000 Pa

Therefore, the pressure at the bottom of the tank due to the paraffin is 20,000 Pascals (Pa).

The mass of the ball is approximately 10.24 kg, found using the conservation of energy principle.

What is the mass of a ball thrown upward with a speed of 10 m/s from a height of 20 m, using the conservation of energy principle?

To find the answer, we can use the conservation of energy principle, which states that the total energy of a system remains constant if there is no net work done on the system.

Initially, the ball has some potential energy due to its height above the ground and kinetic energy due to its motion. As it travels upwards, its potential energy increases while its kinetic energy decreases until it reaches its highest point, at which its kinetic energy is zero and its potential energy is at its maximum. Then, as it falls back down, its potential energy decreases while its kinetic energy increases until it reaches the ground, at which its potential energy is zero and its kinetic energy is at its maximum.

Let's use the following variables:

m = mass of the ball

v_i = initial velocity of the ball (10 m/s)

v_f = final velocity of the ball (0 m/s at the highest point)

h = height of the ball above the ground (20 m)

g =  (9.81 m/s^2)

The total energy of the ball initially is:

E_i = 1/2 * m * v_i^2 + m * g * h

At the highest point, the total energy of the ball is:

E_f = 1/2 * m * v_f^2 + m * g * 2h

Since the ball is at rest at the highest point, its final velocity is zero, so:

E_f = m * g * 2h

By the conservation of energy principle, the total energy of the ball is constant, so:

E_i = E_f

Substituting the expressions for E_i and E_f and solving for the mass of the ball:

1/2 * m * v_i^2 + m * g * h = m * g * 2h

1/2 * v_i^2 + g * h = 2g * h

m = (1/2 * v_i^2 + g * h) / g

m = (1/2 * 10^2 + 9.81 * 20) / 9.81

m = 10.24 kg

Therefore, the mass of the ball is approximately 10.24 kg.

Answer: 15m/s

Explanation: Average Velocity is vector describing the total displacement of an object and the time taken to change its position. It is represented as:

\(v=\frac{\Delta x}{\Delta t}\)

At t₁ = 1.0s, displacement x₁ is:

\(x(1)=25+3(1)^{2}\)

x(1) = 28

At t₂ = 4.0s:

\(x(4)=25+3(4)^{2}\)

x(4) = 73

Then, average speed is

\(v=\frac{73-28}{4-1}\)

v = 15

The average velocity of a car between t₁ = 1s and t₂ = 4s is 15m/s

Work done by gravity when it moves from A to C will be 288.6 joule

873.2 = 7.4v2 + 473.6

v = 7.34 m/s

It should be noted that to find velocity at C, which has come down to a height of 2 meter, it means it has travelled by 5.9-2 =3.9 m

so, v2 = 2gh = 20x3.9 =

Answer:

If 99.995 A  pass thru a shunt and 5 mA pass thru the meter, the meter will have full scale deflection for a current of 100 A.

By Ohm's Law  

99.995 Rs = .005 Rm

Rs = .005 / 99.995 * 120

Rs = .006 ohms

Using a shunt resistance of .006 Ω will produce the required result.

The value of the shunt resistor should be very low to divert most of the current, use a shunt resistor with a value of 0.0012 ohms.

The value of the shunt resistor (Rs) is:

Rs = (Rm × Im) ÷ (If - Im)

where:

Rs = Shunt resistor value

Rm = Resistance of the milliammeter

Im = Full-scale current of the milliammeter

If = Maximum current we want to measure

The shunt resistor value:

Rs = (120 × 5 ) ÷ (100  - 5)

Rs = (0.12 ) ÷ (100 - 0.005)

Rs = 0.12 ÷ 99.995

Rs = 0.00120018 ohms

The given scenario involves calculating the acceleration of an object propelled by a force of 10 N with a mass of 30 kg. The object will accelerate at a rate of 0.333 m/s².

The equation for calculating acceleration is:

acceleration = force / mass

where acceleration is measured in meters per second squared (m/s²), force is measured in Newtons (N), and mass is measured in kilograms (kg).

Given:

mass = 30 kg

force = 10 N

To find the acceleration, we can substitute these values into the equation:

acceleration = force / mass

acceleration = 10 N / 30 kg

acceleration = 0.333 m/s²

Therefore, the object will accelerate at a rate of 0.333 meters per second squared. This means that for every second that passes, the object's velocity will increase by 0.333 meters per second.

It's worth noting that the direction of the force is also important in determining the direction of the acceleration. If the force is applied in the same direction as the motion of the object, it will speed up, but if the force is applied in the opposite direction, it will slow down.

The distance travelled by the plane in the first second of its run is 5m.

Velocity is defined as the rate of change of a body’s position with respect to time. Velocity is basically speeding in a specific direction. It is a vector quantity, which means we need both magnitude (speed) and direction to define velocity. If there is a change in magnitude or the direction of velocity of a body, then it is said to be accelerating.

From the question;

velocity (acceleration) = 5m/s2

distance = 1800m

so, to find the distance travelled in the first second;

time = 1 second

using the formula; \(velocity = \frac{displacement}{time}\)

therefore; displacement = velocity x time

displacement = 5 x 1

displacement = 5m

Answer:

A.) 230 km

B.) 76.67 km/h

Explanation:

Given that On a straight road (taken to be in the +x direction) you drive for an hour at 50 km per hour, then quickly speed up to 90 km per hour and drive for an additional two hours.

A.) How far do you go?

When driving for an hour, the distance covered will be

Distance = speed × time

Distance = 50 × 1 = 50 km

When driving for additional 2 hours, the distance covered will be

Distance = 90 × 2 = 180 km

Total distance = 180 + 50 = 230 km

b. What is your average x component of velocity?

Average Velocity = total distance/ total time

Average velocity = 230/3

Average velocity = 76.67 km/h

Due to its centre of mass being too high and because of that it is at a high risk of toppling at the corner

Answer:

1.84 m

Explanation:

For the small lead ball to be balanced at the tip of the vertical circle just before it is released, the reaction force , N equal the weight of the lead ball W + the centripetal force, F. This normal reaction ,N also equals the tension T in the string.

So, T = mg + mrω² = ma where m = mass of small lead ball, g = acceleration due to gravity = 9.8 m/s², r = length of rope = 1.10 m and ω = angular speed of lead ball = 3 rev/s = 3 × 2π rad/s = 6π rad/s = 18.85 rad/s and a = acceleration of normal force. So,

a = g + rω²

= 9.8 m/s² + 1.10 m × (18.85 rad/s)²

= 9.8 m/s² + 390.85 m/s²

= 400.65 m/s²

Now, using v² = u² + 2a(h₂ - h₁)  where u = initial velocity of ball = rω = 1.10 m × 18.85 rad/s = 20.74 m/s, v = final velocity of ball at maximum height = 0 m/s (since the ball is stationary at maximum height), a = acceleration of small lead ball = -400.65 m/s² (negative since it is in the downward direction of the tension), h₁ = initial position of lead ball above the ground = 1.3 m and h₂ = final position of lead ball above the ground = unknown.

v² = u² + 2a(h₂ - h₁)

So, v² - u² = 2a(h₂ - h₁)

h₂ - h₁ =  (v² - u²)/2a

h₂ =  h₁ + (v² - u²)/2a

substituting the values of the variables into the equation, we have

h₂ =  1.3 m + ((0 m/s)² - (20.74 m/s)²)/2(-400.65 m/s²)

h₂ =  1.3 m + [-430.15 (m/s)²]/-801.3 m/s²

h₂ =  1.3 m + 0.54 m

h₂ =  1.84 m

Explanation: The volume flow rate of the water remains constant as it flows from the larger pipe to the smaller pipe. Therefore, we can use the equation:

A1v1 = A2v2

where A1 and v1 are the cross-sectional area and velocity of the larger pipe, and A2 and v2 are the corresponding values for the smaller pipe.

The cross-sectional area of a pipe is given by the formula:

A = πr^2

where r is the radius of the pipe.

Substituting the given values, we get:

π(0.4)^2(15) = π(r^2)(45)

Simplifying and solving for r, we get:

r = 0.13 m

Therefore, the radius of the smaller pipe is 0.13 m.

• time taken = 30 min = 0.5 h

Substituting these values into the equation:

                          ⇒ \(\bf 900 \space\ km/h\)

It would take approximately 546 days for the decay rate of the sample of this radioactive isotope to fall to 0.58 of its initial rate.

1. The decay rate of a radioactive isotope is proportional to the number of radioactive atoms present in the sample at any given time.

2. The decay rate can be expressed as a function of time using the formula: R(t) = R₀ * \(e^{(-\lambda t\)), where R(t) is the decay rate at time t, R₀ is the initial decay rate, λ is the decay constant, and e is the base of the natural logarithm.

3. The half-life of a radioactive isotope is the time it takes for half of the radioactive atoms in a sample to decay. In this case, the half-life is given as 210 days.

4. Using the half-life, we can find the decay constant (λ) using the formula: λ = ln(2) / T₁/₂, where ln(2) is the natural logarithm of 2 and T₁/₂ is the half-life.

5. Substituting the given half-life into the formula, we have: λ = ln(2) / 210.

6. Now, we need to find the time it takes for the decay rate to fall to 0.58 of its initial rate. Let's call this time "t".

7. Using the formula for the decay rate, we can write: 0.58 * R₀ = R₀ * e^(-λt).

8. Simplifying the equation, we get: 0.58 = \(e^{(-\lambda t\)).

9. Taking the natural logarithm of both sides, we have: ln(0.58) = -λt.

10. Substituting the value of λ from step 5, we get: ln(0.58) = -(ln(2) / 210) * t.

11. Solving for t, we have: t = (ln(0.58) * 210) / ln(2).

12. Evaluating the expression, we find: t ≈ 546.

13. Therefore, it would take approximately 546 days for the decay rate of the sample of this radioactive isotope to fall to 0.58 of its initial rate.
