The quantity that must be measured in order to calculate the coefficient of friction is angle at which the surface is tilted

Since the block of mass m slides at a constant speed,

a = 0

If tilted at an angle θ,

∑ Fy = m ay

N - Wy = 0

N = m g cos θ

∑ Fx = m ax

Wx - f = 0

f = m g sin θ

f = μ N

f = Frictional force

μ = Co efficient of friction

N = Normal force

μ = f / N

μ = m g sin θ / m g cos θ

μ = sin θ / cos θ

μ = tan θ

μ ∝ θ

Therefore, to calculate the coefficient of friction, the quantity that needs to be measured is angle of tilt

Answer:

A) OA, AB, BC

B) 25m/s^2

C) see explanation

D) 25

E) Rest

Explanation:

From the Velocity time graph shown:

The positive slope = OA ; This is positive because, it is the point of uniform acceleration on the graph.

Constant slope = AB, the slope here is constant because, AB on the graph is the point of constant velocity.

-ve slope = BC

B) Acceleration of body in path OA.

Acceleration = change in Velocity / time

Acceleration = (150 - 0) / 6

Acceleration = 150/6 = 25m/s^2

C) Path AB is Parallel to the because it marks the period of constant velocity (that is Velocity does not increase or decrease during the time interval).

D) Length of BC

BC corresponds to the distance moved, that velocity / time

Velocity = 150 ; time = 6

Therefore Distance (BC) = 150/6 = 25

E.) Velocity =0 ; Hence body is at rest

Scientists believe that Titan, one of Saturn's moons, has an atmosphere, while the large moons of Jupiter (Ganymede, Callisto, Europa, and Io) do not have significant atmospheres. The main reason for this difference lies in their respective environments and the processes occurring on these moons.

Titan has a thick atmosphere primarily composed of nitrogen, with smaller amounts of methane and other hydrocarbons. This atmosphere likely exists due to the presence of organic compounds on the moon's surface, as well as ongoing geological and atmospheric processes. Titan's atmosphere is maintained through a combination of surface evaporation, volcanic activity, and photochemical reactions.

In contrast, the large moons of Jupiter have relatively tenuous or no significant atmospheres. This is because their environments differ from that of Titan. Ganymede, Callisto, and Europa are icy moons with subsurface oceans, while Io is volcanically active. These moons lack the conditions necessary for the sustained presence of a thick atmosphere. The extreme temperatures, low atmospheric pressures, and different compositions and geological activities on these moons contribute to their lack of significant atmospheres.

Overall, the presence or absence of an atmosphere on a moon depends on multiple factors, including composition, geological activity, presence of volatile substances, and environmental conditions specific to each moon.

Answer:

The distance in front of the target is 9.524 km

Explanation:

Given;

height of the bomber above the ground, h = 9 km = 9000 m

velocity of the bomber, v = 800 km/h = 222.22 m/s

The time the bomb will get to the target is given by;

\(t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2*9000}{9.8} }\\\\ t = 42.857 \ s\)

The lead distance or distance in front of the target is given by;

x = vt

x = (222.22 m/s) x (42.857 s)

x = 9523.68 m

x = 9.524 km

Therefore, the distance in front of the target is 9.524 km

In front of the target, the distance will be "9.524 km".

According to the question,

Bomber's height, h = 9 km or,

                                = 9000 m

Bomber's velocity, v = 800 km/h or,

                                  = 222.22 m/s

Now,

The time will be:

→ t = \(\sqrt{\frac{2h}{g} }\)

By substituting the values, we get

     = \(\sqrt{\frac{2\times 9000}{9.8} }\)

     = \(\sqrt{\frac{18000}{9.8} }\)

     = 42.857 s

hence,

The lead distance will be:

→ x = vt

By putting the values,

     = 222.22 × 42.857

     = 9523.68 or,

     = 9.524 km

The frequency of 20-mm microwaves is approximately 1.5 × 10^10 Hz. (c = 3.0 × 108 m/s) .

The frequency of microwaves with a wavelength of 20 mm, we can use the wave equation:

c = λ * ν

Where:

c = speed of light (3.0 × 10^8 m/s)

λ = wavelength

ν = frequency

First, we need to convert the wavelength from millimeters to meters:

λ = 20 mm = 20 × 10^(-3) m

Now, we can rearrange the equation to solve for the frequency (ν):

ν = c / λ

Substituting the values:

ν = (3.0 × 10^8 m/s) / (20 × 10^(-3) m)

ν = (3.0 × 10^8) / (20 × 10^(-3))

ν = 1.5 × 10^10 Hz

The given statement, "When a car goes around a curve of smaller and smaller radius, the centripetal force on it decreases." is false.

The centripetal force required to keep a car moving in a curved path at a constant speed is directly proportional to the square of its velocity and inversely proportional to the radius of the curve.

As the radius of the curve decreases, the required centripetal force increases, not decreases. If the centripetal force on the car decreases, it would move out of its circular path, implying a decrease in velocity or radius of curvature.

Answer: The angular velocity at which the centripetal acceleration is 11.25 g, with a radius of 16.5 m, is approximately 2.59 rad/s.

Explanation:

Centripetal acceleration (ac) = angular velocity (ω)² × radius (r)

Here, the centripetal acceleration is given as 11.25 g, where g is the acceleration due to gravity (approximately 9.8 m/s²). The radius is given as 16.5 m.

First, we need to convert 11.25 g to meters per second squared (m/s²):

11.25 g = 11.25 × 9.8 m/s² ≈ 110.25 m/s²

Substituting the known values into the formula, we have:

110.25 m/s² = ω² × 16.5 m

To solve for the angular velocity (ω), we can rearrange the equation as follows:

ω² = 110.25 m/s² / 16.5 m

ω² ≈ 6.7 rad²/s²

Taking the square root of both sides, we find:

ω ≈ √6.7 rad/s =2.59 rad/sec

B. Increase in proportion to the wavelength of a wave.

Explanation:

An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.

Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.

Wavelength is simply the distance from one peak of an electromagnetic wave to the next peak. This distance is also equal to the distance from one trough of a wave to another.

Mathematically, wavelength is calculated using this formula;

\( Wavelength = \frac {speed}{frequency} \)

Hence, the waves in the electromagnetic spectrum have a speed that increase in proportion to the wavelength of a wave.

The process by which plastic deformation is produced by dislocation motion is called slip deformation.

When applied stress exceeds the elastic limit or yield stress, the deformation of the material body occurs. This is due to the result of a slip or dislocation mechanism at the atomic level. Plastic deformation in a metal has two prominent mechanisms, and they are. When we apply a shear stress on an object in a particular direction to change its shape or anything that we cam do. the shear stress generate a strain on the object and changes its shape to the extent that we can do by the force. the shape is changed to the extent by the force applied on the part of it and we can take a look into it.
