Answer:

Tripled

Explanation:

The relation between the tangential speed and the angular speed is given by

v = r ω

where, r is the radius of the circular path and ω be the angular velocity

As we know that

ω = 2π f

Where, f is the frequency of rotation in rpm

So, v = 2π f r

As the RPM becomes tripled, the tangential velocity is also tripled.

Answer:

the kinetic energy is transformed into heat energy evident by the warmth of the tires and is dissipated.

When a car is braked to a stop, its kinetic energy is transformed into heat energy.

Energy cannot be created or destroyed, according to the law of conservation of energy. However, it is capable of change from one form to another. An isolated system's total energy is constant regardless of the types of energy present. The law of energy conservation is adhered to by all energy forms.

In a nutshell, the law of conservation of energy asserts that the system's total energy is conserved in closed systems, or systems that are separated from their environment.

To find acceleration using velocity and distance, use the kinematic equation v² = vo² + 2a(d − do). If the object starts from rest, rearrange the equation to solve for acceleration: a = (v² - vo²)/2d. Keep in mind that this approach assumes constant acceleration and ignores forces such as air resistance and friction.

To find acceleration when given distance and velocity, you can use physics' kinematic equations that relate displacement, velocity, acceleration, and time. One of these equations is v² = vo² + 2a(d − do), where v is the final velocity, vo is the initial velocity, a is the acceleration, and d is the displacement or distance.

First, to find acceleration (a), you have to ensure that the initial velocity (vo) is zero (when the object starts from rest). After this, rearrange the equation to solve for acceleration: a = (v² - vo²)/(2d). This will help you find the acceleration when you plug in your given final velocity (v) and distance (d).

Note: This method assumes a constant acceleration and does not consider forces like friction or air resistance. It's fundamental to consider this when dealing with real-world problems.

Final answer:

Momentum depends on mass and velocity, and in this scenario, the basketball will have three times more momentum than the softball despite moving at the same velocity. Understanding momentum is key in analyzing the effects of collisions and interactions involving objects of different masses and velocities.

Explanation:

Momentum is a measure of how hard it is to stop an object and depends on both mass and velocity. The momentum of an object (p) is given by the product of its mass (m) and velocity (V): p = mV. In the given scenario, if a basketball has three times greater mass than a softball but both are moving at the same velocity, the basketball will have three times more momentum compared to the softball.

This difference in momentum reflects the impact a player with a greater mass but the same velocity can have in collisions, as momentum is crucial in determining the effect of such interactions. Therefore, if the mass of the softball is m, and the velocity of both the softball and basketball is v, then the momentum of the softball will be m × v and the momentum of the basketball will be 3m × v, which is three times greater than that of the softball.

To find the mass of the crate on a frictionless incline with a known force and acceleration, use Newton's second law. The mass is calculated as 40 N divided by 2.0 m/s^2, resulting in 20 kg.

To determine the mass of the crate on an incline, you can use Newton's second law of motion, which is F = ma, where F is the force, m is the mass, and a is the acceleration. In this case, we know the force applied up the incline (40 N), the acceleration of the crate (2.0 m/s2), and we need to determine the mass m. The equation can be rearranged to solve for mass by dividing both sides by acceleration, resulting in m = F/a. Thus, dividing the force by the acceleration, you get m = 40 N / 2.0 m/s2 = 20 kg. So, the mass of the crate is 20 kilograms.

Planck's equation can be used as a formula to determine the energy of a photon. In this problem, given the frequency and using 6.63 x 10^-34 J.s as Planck's constant, the energy can be calculated. This Physics concept is useful in understanding the energy-frequency relationship of photons.

To calculate the energy of a photon, we can use the Planck's equation E = hv, where 'E' is the energy of the photon, 'h' is the Planck's constant and 'v' is the frequency of the photon.

In this case, the frequency of the photon 'v' is given as  3.55 x 10^17 Hz and Planck's constant 'h' is a universally accepted constant which is 6.63 x 10^-34 J.s. Substituting these values into Planck's equation we get:

E = 6.63 x 10^-34 J.s x 3.55 x10^17 Hz

Upon calculating, the energy in Joules of the photon can be found.

Further explanation:

The opposition that every object feels when it moves is known as the frictional force. This is an opposing force. It always acts in the opposite direction of the motion of the object.

Given:

The angle of inclination of plane is [tex]{17^ \circ }[/tex].  

The acceleration due to gravity is [tex]9.8\,{\text{m/}}{{\text{s}}^{\text{2}}}[/tex].

Concept used:

The frictional force is defined as the opposition of motion of any object or body.  It is also defined as the product of coefficient of friction to the normal force exerted on the body.

The expression for the net force exerted on the mug is given as.

[tex]{F_{{\text{net}}}} = mg\sin \theta[/tex]                                                                         …… (1)

Here, m is the mass of the mug, g is the acceleration due to gravity and [tex]\theta[/tex]  is the inclination angle.

The force that keeps the body at rest is known as the static friction force. It also acts in the opposite direction of motion of body.

The expression for the static frictional force is given as.

[tex]{F_s} = {\mu _s}N[/tex]                                                              ..…. (2)

Here, [tex]{\mu _s}[/tex] is the coefficient of static frictional force and N is the normal force exerted on the body.

When mug is placed on the inclined plane the static frictional force is equal to the frictional force. The vertical component of weight is balanced by the normal reaction of the mug.

The expression for the normal force is given as.

[tex]N - mg\cos \theta=0[/tex]

Rearrange the above expression.

[tex]N = mg\cos \theta[/tex]

Substitute [tex]mg\cos \theta[/tex]  for N in equation (2).

in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Color is the frequency of the light and wavelength is the speed of that light. Depending on the color it will have a higher frequency and a smaller wavelength while another will have a lower frequency and a longer wavelength so that the colors will even out. Hope this helps.

The color of light is determined by its wavelength. In the visible light spectrum, longer wavelengths are perceived as red, while shorter wavelengths are perceived as blue or violet. This is evident in phenomena like rainbows.

The relationship between color and wavelength for light is that the color of light that we perceive is determined by the wavelength of the light. In the visible light spectrum, each color corresponds to a different range of wavelengths. For instance, red light has longer wavelengths (about 700 nM to 635 nM), whereas blue or violet light has shorter wavelengths (around 450 nM to 400 nM). This is why when we see a rainbow, it is a gradation of colors from red (long wavelength) at the top to violet (short wavelength) at the bottom. This happens because of the refraction and dispersion of light in droplets of water.

First calculate for the time it takes for the model rocket to reach the land. Using the formula:

h = vi t + 0.5 g t^2

where h is height = 100 m, vi is initial vertical velocity = 0 since it simply dropped, t is time = ?, g = 9.8 m/s^2

100 = 0.5 (9.8) t^2

t = 4.52 seconds

So the total horizontal distance taken is:

d = 50 m/s * 4.52 s

d = 225.90 m

The distance from the edge of the cliff where the model rocket will land is ; 225.90 m

Using the given data :

Velocity of rocket = 50.0 m/s

Depth of canyon ( H ) = 100 m deep

Initial velocity ( vi ) = 0

To determine how far from the edge of the cliff does the model rocket land

H = vi( t ) + 0.5gt²

100 = 0.5*(9.8)*t²

∴ t = 4.52  secs

Velocity = horizontal distance / time

∴ distance ( horizontal distance ) = velocity * time

   distance = 50 m/s * 4.52 secs = 225.90 m

Hence we can conclude that The distance from the edge of the cliff where the model rocket will land is ; 225.90 m .
