Magnitude of the acceleration of fan blades will be approximately 165.9 m/s2

The first step is to convert the rotational speed from revolutions per minute (RPM) to radians per second (rad/s), since acceleration is measured in meters per second squared (m/s^2), which is a linear unit of measurement. We can use the conversion factor:

1 revolution = 2π radians

Therefore, 339.0 rev/min is equal to:

339.0 rev/min * (2π rad/1 rev) * (1 min/60 s) = 35.6 rad/s

The acceleration of a point on one of the fan blades can be found using the formula for centripetal acceleration:

a = rω^2

where:

a is the centripetal acceleration

r is the radius of the fan blade (0.13 m)

ω is the angular velocity in radians per second (35.6 rad/s)

Plugging in the values:

a = (0.13 m)(35.6 rad/s)^2

a = 165.9 m/s^2 (rounded to three significant figures)

Therefore, the magnitude of the acceleration of a point on one of the fan blades is 165.9 m/s^2.

Answer:

There will be a force of gravity and a normal force coming from the track itself.

Explanation:

Assuming this is a continuation of an earlier question [20398149], the crate starts at rest and is allowed to slide down the ramp with acceleration a = 2.35 m/s², so the block will have some speed as it reaches the bottom of the ramp and it will continue to slide some distance along the flat part.

If the flat part is made of the same material as the ramp, then in addition to its own weight and the normal force, the crate will also feel some friction that slows down its leftward slide.

• The crate's weight and the normal force act vertically, so that

∑ F = n - w = 0

n = w = mg = (100 kg) (9.8 m/s²) = 980 N

(where ∑ F = net force, n = magnitude of normal force, w = crate weight, m = crate mass, g = mag. of gravitational acceleration)

• The friction acts horizontally, so

∑ F = -f = m a

(where f = mag. of friction and a = crate acceleration)

The surface has a coefficient of kinetic friction of µ = 0.3, so

f = µ n = 0.3 (980 N) = 294 N

So at the bottom of the ramp, there are 3 forces exerted on the crate:

• its weight of 980 N pointing downward

• the normal force of the surface pushing upward on the crate, also of 980 N

• friction of 294 N, pointing to the right

and the two vertical forces cancel each other.

A wire is connected to a 6V battery. At 20°C, the current is 2A whereas at 100°C the current is 1.7 . The temperature coefficient of resistivity (α) of the material of the wire is a. 1.1 x 10-3 °C

To find the temperature coefficient of resistivity (α) of the material of the wire, we'll use the formula:

α = (R₂ - R₁) / [R₁(T₂ - T₁)]

where R₁ and R₂ are the resistances at temperatures T₁ and T₂, respectively.

First, let's calculate the resistances at 20°C (T₁) and 100°C (T₂) using Ohm's Law (V = IR):

R₁ = V / I₁ = 6V / 2A = 3Ω (at 20°C)
R₂ = V / I₂ = 6V / 1.7A ≈ 3.53Ω (at 100°C)

Now, we can find α using the formula:

α = (3.53Ω - 3Ω) / [3Ω(100°C - 20°C)]
α ≈ 0.53Ω / (3Ω * 80°C)
α ≈ 0.000221 °C⁻¹

The closest answer choice to the calculated α is (a) 1.1 x 10⁻³ °C, though there's a slight difference between the calculated value and the provided options.

Solar Energy

Explanation:

Solar radiation (a form of an object) heats up our atmosphere, that's why heat is felt on earth.

The streamlines equations are \(x^2 - y^2 = c_1\) and \(xy = c_2\), where \(c_1\) and \(c_2\) are constants.

The velocity field is given by,

\(V_x = x (x^2 + y^2)^-^1^/^2\)

\(V_y = y (x^2+ y^2)^-^1^/^2\)

Now, we know that the tangent to a streamline is always parallel to the velocity vector. Hence, for the streamline equations, we must have

\(dx/dy = V_x/V_y\)

Therefore,\((x/y) = V_x/V_y = x/y\)

⇒ \(x^2 - y^2 = c_1\)

or, \((x+y)(x-y) = c_1\)

Hence, the equation of the streamlines are given by \(x^2 - y^2 = c_1\)

Now, for the other streamline equation, let's differentiate both sides of \(V_x\)= constant along the streamline:

\(dx/ds = constant/y\)

And differentiate both sides of \(V_y\) = constant along the streamline:

\(dy/ds = constant/x\)

Multiplying both equations, we get

\(xdx/ds = ydy/ds\)

or,\(xdx = ydy\)

Integrating, we get

\(x^2/2 = y^2/2 + c_2\)

or,\(xy = c_2\)

Thus, the equations of the streamlines are \(x^2 - y^2 = c_1\) and \(xy = c_2\)

The primary indicator of an object's position and speed is its velocity.It is the distance that an object travels in one unit of time.The displacement of the item in one unit of time is the definition of velocity.

Smax = 400 feet.

c) v = 32 ft/s

c) v = - 32 ft/s

(a)

The following is the function provided for ball height:

s = 160 t - 16 t²

Therefore, we must take the derivative with respect to t and make it equal to zero in order to get the time to reach maximum height (in-flexion point):

So, 160 - 32 t = 0, 32 t = 160 t, and 160/32 t = 5 sec.

As a result, the maximum distance is covered every 5 seconds.

Smax = (160)(5) - (16)(5)²

Smax = 800 - 400

Smax=400 feet

b)First, we determine the speed at which the ball travels 384 feet.

384 = 160 t - 16 t

16 t² - 160 t + 384 = 0

Quadratic Equation Solving:

Either:

t = 6 sec

or t = 4 seconds

Since it takes 5 seconds to reach the highest point,

t then equals 5 seconds.

t then equals 4 seconds.

Now, by taking a derivative of ods with respect to t at 4 sec, we can find velocity:

v = 160 - 32 t

v = 160 - (32)(4)

v = 32 ft/s

c,Because t = 6 s > 5 s

The second number of t = 6 sec must represent the point in the ball's downward motion when it is 384 feet above the earth.

So, at that moment, velocity will be:

Answer:

\(Speed = \frac{8v}{5}\)

Explanation:

Given

\(Speeds: v\ and\ 2v\)

Required

Determine the average speed

First, we need to determine the time spent on the journey

\(Time = Distance/Speed\)

For the first \(\frac{1}{4}th\)

\(T_1 = \frac{1}{4}/v\)

\(T_1 =\frac{1}{4v}\)

For the next \(\frac{3}{4}th\)

\(T_2 = \frac{3}{4}/2v\)

\(T_2 = \frac{3}{8v}\)

\(Total\ Time = T_1 +T_2\)

\(T = \frac{1}{4v} + \frac{3}{8v}\)

\(T = \frac{2+3}{8v}\)

\(T = \frac{5}{8v}\)

Average Speed is then calculated as thus:

\(Speed = Distance/Time\)

\(Speed = (\frac{1}{4} + \frac{3}{4})/\frac{5}{8v}\)

\(Speed = (\frac{1+3}{4})/\frac{5}{8v}\)

\(Speed = (\frac{4}{4})/\frac{5}{8v}\)

\(Speed = 1/\frac{5}{8v}\)

\(Speed = 1 * \frac{8v}{5}\)

\(Speed = \frac{8v}{5}\)

Hence;

Option 1 answers the question

Answer: 1. \(\frac{8v}{5}\)

Explanation: Speed is a variable in Physics defined by the rate at which an object go through a distance. It can be calculated as:

\(speed=\frac{distance}{time}\)

A fourth of distance with speed v takes:

\(speed=\frac{distance}{time}\)

\(time=\frac{distance}{speed}\)

\(time=\frac{1}{4v}\)

The rest of the distance with speed 2v takes:

\(time=\frac{3}{4*2v}\)

\(time=\frac{3}{8v}\)

Average speed is given by:

\(average=\frac{distance_{traveled}}{time_{travel}}\)

Total time to cover the distance:

\(time=\frac{1}{4v}+\frac{3}{8v}\)

\(time=\frac{2+3}{8v}\)

\(time=\frac{5}{8v}\)

Total distance traveled:

\(d=\frac{1}{4} +\frac{3}{4}\)

d = 1

average = 1 ÷ \(\frac{5}{8v}\)

\(average=\frac{8v}{5}\)

The average speed of particle is 8/5v.

The power loss due to friction per meter of the pipe is approximately 0.00393 W/m.

We can use the Darcy-Weisbach equation to determine the pressure drop per metre of the pipe:

ΔP = f * (L/D) * (ρ/2) * V^2

where: f = friction factor and P = pressure drop

L stands for pipe length.

Pipe diameter is given by D.

= the water's density.

V = water's speed

In order to ascertain the type of flow, we can first compute the Reynolds number (Re):

Re = (ρ * V * D) / μ

where: = the water's viscosity

Water has a density of 1000 kg/m3 and a viscosity of 1.002 x 10-3 Pa.

Re is equal to (1000 kg/m3 x 0.1 m/s x 0.2 m) / (1.002 x 10-3 Pa/s) 199,203.

1 / f is equal to -2.0 * log10((/D)/3.7 + (2.51/(Re * f)))

where is the pip's roughness height.

We can now determine the pressure drop:

P = f (L/D) * (L/D) * (L/D) * (L/D) * (/2) * V2 = 0.025 * (1 m / 0.2 m) * (1000  kg/m³ / 2) * (0.1 m/s)^2

≈ 1.25 Pa/m

Therefore, the pressure drop per meter of the pipe is approximately 1.25 Pa/m.

P = ΔP * Q

where:

P = power loss

Q = flow rate (volume flow rate)

Assuming the pipe is completely filled with water, the flow rate can be calculated as:

Q = (π/4) * D^2 * V

Q = (π/4) * (0.2 m)^2 * (0.1 m/s) ≈ 0.00314 m³/s

Now we can calculate the power loss:

P = ΔP * Q

In order to form a hypothesis that would illustrate the relationship between mass and kinetic energy, we first need to understand what kinetic energy and mass are and how they are related. Kinetic energy is the energy that an object possesses due to its motion, and is given by the formula KE = 0.5mv², where m is the mass of the object and v is its velocity. Mass, on the other hand, is a measure of the amount of matter in an object.

The relationship between mass and kinetic energy is direct, meaning that as mass increases, so does kinetic energy, provided that velocity remains constant. Similarly, if velocity increases, then kinetic energy will increase as well, provided that mass remains constant.

The hypothesis that illustrates this relationship can be stated as follows:If the mass of an object is increased, then the kinetic energy of the object will also increase, because kinetic energy is directly proportional to mass, assuming velocity remains constant.In other words, if the mass of an object is doubled, then its kinetic energy will also double, assuming that its velocity remains constant.
