The average speed of the motorcycle is equal to 64 m/s.

The average speed of a moving object can be described as the total distance traveled by it in a definite time interval. The average speed is a scalar quantity because it carries only the magnitude and no direction.

The average speed can be determined from the ratio of the total distance to the time taken to cover that distance.

The average speed formula can be written as follows:

Average speed =  Total distance / total time taken

Given, the distance covered by the motorcycle  = 1600 m

The total time taken by motorcycle = 25 sec

The average speed of the train = 1600/25 = 64 m/s

Therefore, the average speed of the given motorcycle is 64 m/s.

Answer:

this ans is 42.85

Explanation:

i dont not explain but i hipe you get it

Answer:

Since these two forces are of equal magnitude and in opposite directions, they balance each other. The book is said to be at equilibrium. There is no unbalanced force acting upon the book and thus the book maintains its state of motion. When all the forces acting upon an object balance each other, the object will be at equilibrium; it will not accelerate.

Explanation:

The basic difference is that the motion of object remain unchanged in case of balanced forces while it changes when an object experiences unbalanced forces

When the forces experienced by an object have equal strength and are acting in opposite directions, they are known as balanced forces while the forces those differ in strength and are probably acting in any direction except opposite, they are known as unbalanced forces.

The balanced forces cancel out each other, and the motion of the object remains unchanged but unbalanced forces can change the velocity or direction of a moving object

After the collision, Ball 1 continues moving to the right with a velocity of 3.8 m/s, while Ball 2 remains stationary.

In a perfectly elastic collision, both momentum and kinetic energy are conserved. To determine the magnitude and direction of each ball's velocity after the collision, we can apply the principles of conservation of momentum and kinetic energy.

Let's denote the golf ball moving to the right as Ball 1 and the initially stationary golf ball as Ball 2. According to the law of conservation of momentum, the total momentum before the collision is equal to the total momentum after the collision:

(mass of Ball 1) x (velocity of Ball 1 before collision) + (mass of Ball 2) x (velocity of Ball 2 before collision) = (mass of Ball 1) x (velocity of Ball 1 after collision) + (mass of Ball 2) x (velocity of Ball 2 after collision)

Applying the values given in the problem:

(0.44 kg) x (3.8 m/s) + (0.22 kg) x (0 m/s) = (0.44 kg) x (v1) + (0.22 kg) x (v2)

where v1 and v2 represent the velocities of Ball 1 and Ball 2 after the collision, respectively.

Since Ball 2 is initially at rest, its velocity after the collision is v2 = 0 m/s.

Solving the equation, we find:

(0.44 kg) x (3.8 m/s) = (0.44 kg) x (v1)

1.672 kg·m/s = 0.44 kg·v1

Dividing both sides by 0.44 kg, we get:

v1 ≈ 3.8 m/s

Therefore, the magnitude and direction of Ball 1's velocity after the collision is approximately 3.8 m/s to the right.

Since Ball 2 is initially at rest, its velocity after the collision remains 0 m/s.

Hence, after the collision, Ball 1 continues moving to the right with a velocity of 3.8 m/s, while Ball 2 remains stationary.

To determine the separation distance between the charges, we can use Coulomb's Law, which states that the force between two charged objects is proportional to the product of their charges and inversely proportional to the square of the distance between them. The formula for Coulomb's Law is:

F = k * (|q1| * |q2|) / r^2

Where:

F is the force between the charges,

k is the electrostatic constant (k ≈ 9 x 10^9 Nm^2/C^2),

|q1| and |q2| are the magnitudes of the charges,

r is the separation distance between the charges.

Given:

|q1| = 5.0 x 10^-6 C,

|q2| = 6.0 x 10^-6 C,

F = -0.72 N.

The acceleration of the crate is approximately 1.84 m/s^2. the speed of the crate, when it reaches the bottom of the incline, is approximately 0.057 m/s.

A. To determine the acceleration of the crate as it slides down the plane, we can use the following equation:

acceleration = g * sin(θ) - μk * g * cos(θ),

where g is the acceleration due to gravity (approximately 9.8 m/s^2), θ is the angle of the plane, and μk is the coefficient of kinetic friction.

Plugging in the values, we have:

acceleration = (9.8 m/s^2) * sin(29°) - (0.19) * (9.8 m/s^2) * cos(29°).

Calculating this expression, the acceleration of the crate is approximately 1.84 m/s^2.

B. To find the speed of the crate when it reaches the bottom of the incline, we can use the following equation:

speed = √(2 * acceleration * distance),

where acceleration is the value we calculated in part A and distance is the height of the incline (8.15 mm or 0.00815 m).

Plugging in the values, we get:

speed = √(2 * 1.84 m/s^2 * 0.00815 m).

The true statements concerning Planck's quantum hypothesis are:

a. An upper limit is set on the amount of energy that can be absorbed or emitted in oscillations.

d. The energy of the oscillations of atoms within molecules must be quantized.

Planck's quantum hypothesis revolutionized our understanding of energy by proposing that energy is not continuous but exists in discrete units called quanta. This hypothesis was introduced to explain the behavior of blackbody radiation and has had profound implications in the field of quantum mechanics. Statement a is true because according to Planck's quantum hypothesis, energy is quantized, meaning it can only be absorbed or emitted in specific amounts. This implies that there is an upper limit to the amount of energy that can be absorbed or emitted in oscillations. This upper limit is determined by the quantum nature of energy.

Explanation:

Answer:

The average speed of 3.5 m/s means that it takes Sally approximately 47.619 minutes to run 10,000 meters

Explanation:

Average speed is a scalar quantity that is given by dividing the total distance moved or traveled by an object by the time that it takes the object during the motion

The average peed indicates the rate at which the object makes a given amount of journey distance given that the journey is completed with varying speeds

With the knowledge of the average speed and the distance covered, the time for completion of the journey can be found as follows;

\(Average \ speed , \overline v = \dfrac{\Delta x}{\Delta t}\)

Where

\(\overline v\) = Average speed of the object = 3.5 m/s

Δt = The time it takes the Sally to run 10,000 meters

Δx = The total distance Sally runs = 10,000 meters

Therefore;

\(\Delta t = \dfrac{\Delta x}{ \overline v} = \dfrac{10,000 \ m}{3.5 \ m/s} = \dfrac{20,000}{7} \ s \approx 2,857.143 \ s\)

The time it takes the Sally to run 10,000 meters= Δt = 20,000/7 seconds ≈ 2,857.143 seconds

20,000/7 seconds ≈ 47.619 minutes

Therefore, the average speed of 3.5 m/s means that the time it takes the Sally to run 10,000 meters ≈ 47.619 minutes

grav times mass equals force

Explanation:

The power of the rocket has a mass of 1000 kg is 16,33,333.33 Watt

The mass of the rocket = 1000 kg

The rocket travels at a constant speed for 60 s

The displacement of the rocket = 10000 m

The formula to find the power of the rocket engine is

               P = F x v

where F is the force and

          v is the velocity

Thus  P = (m x g x d)/t

where m is the mass of the rocket

           g is the acceleration due to gravity

           d is the displacement

           t is the time taken

Let us substitute the known values in the above equation, we get

               P = ( 1000 x 9.8 x 10000 ) / 60

                  = 98000000 / 60

The number of complete waveforms passing a given point per unit time is called frequency.

Frequency is a fundamental concept in wave motion and refers to the rate at which a wave oscillates or repeats within a specified time interval. It is typically measured in units of hertz (Hz), which represents the number of cycles or waveforms completed per second.

In other words, frequency measures how often a wave oscillates or completes a full cycle in a given amount of time. It represents the temporal aspect of a wave and determines the pitch of a sound wave or the color of light waves, among other characteristics.

For example, in the context of sound waves, a higher frequency corresponds to a higher pitch, while a lower frequency corresponds to a lower pitch. In electromagnetic waves, such as visible light, different frequencies correspond to different colors.

The relationship between frequency (f), wavelength (λ), and the speed of the wave (v) is given by the equation:

v = f * λ

where v is the velocity of the wave. This equation shows that frequency and wavelength are inversely proportional. As the frequency increases, the wavelength decreases, and vice versa.

In summary, frequency measures the number of complete waveforms passing a given point per unit time and is a key parameter for characterizing various types of waves, including sound waves, light waves, and electromagnetic waves.

Therefore the codes of her examinations are :

ICD Code :

\($R06.02$\) = shortness of breath

\($M79.1$\) = musculoskeletal pain

\($X50.3XXS$\) = overexertion due to the repetitive body movement

a. The probability that a randomly selected soda can has a volume less than 12 fluid ounces is approximately 0.3085

b. The probability that the sample mean volume is less than 12 fluid ounces, when a sample of size n = 32 is taken, is approximately 0.0023

c. The distribution of the sample mean becomes narrower and more concentrated around the population mean. Consequently, the probability of obtaining a sample mean less than 12 fluid ounces decreases because the sample mean is less likely to deviate significantly from the population mean.

a) Let X be the volume of a randomly selected soda can. We are given that the mean (μ) is 12.01 fluid ounces and the standard deviation (σ) is 0.02 fluid ounces.

We need to calculate P(X < 12). To do this, we standardize the variable using the z-score formula:

z = (X - μ) / σ

Substituting the given values, we have:

z = (12 - 12.01) / 0.02

= -0.5

Now, we can use a standard normal distribution table or calculator to find the probability associated with the z-score of -0.5. From the table, we find that the probability is approximately 0.3085.

b) When a sample of size n = 32 soda cans is drawn randomly from the population, the mean volume of the sample (denoted by X-bar) follows a normal distribution with the same mean (μ = 12.01 fluid ounces) but a smaller standard deviation (σ-bar) given by:

σ-bar = σ / sqrt(n)

Substituting the values, we have:

σ-bar = \(0.02 / \sqrt{(32)\)

= 0.02 / 5.6569

≈ 0.00354

Now, we need to calculate P(X-bar < 12). Again, we standardize the variable using the z-score formula:

z = (X-bar - μ) / σ-bar

Substituting the given values, we have:

z = (12 - 12.01) / 0.00354

≈ -2.8249

Using the standard normal distribution table or calculator, we find that the probability associated with the z-score of -2.8249 is approximately 0.0023.

c) As larger and larger sample sizes are taken, the probability that the sample mean volume is less than 12 fluid ounces tends to decrease. This is because as the sample size increases, the sample mean becomes a better estimate of the population mean. The larger the sample size, the more reliable and representative the sample mean is of the true mean. Hence, the sample mean is more likely to be closer to the population mean.
