Answer:

Normal, Gravitational, Applied, Friction, and Tension

Explanation:

Because the sled is on the ground, or rather because it is on the earth, it will have a force of gravity, or its weight, pulling it down.

There is a normal force because the sled is not moving into the ground, so there needs to be a force pushing on the sled from the ground. Additionally, Newton's 3rd law states that for every action there is an equal but opposite reaction, if it's in equilibrium or not moving.

There will be an applied force since the child is pulling the sled and is applying a force to do so.

There will be a friction force that is pulling the sled opposite the direction it is moving, since it is on the ground that is presumably not fricitonless.

There will be a tension force pulling on the sled by the rope. However there is also a tension force pulling on the child's hand by the rope, meaning that these are internal forces and essentially balance out, but they are still there.

There is no air resistance force, or very little of it, since the object is not falling.

Answer:

by using formula,

wavelength= velocity/frequency

= 120/6

= 20 meter

Ans: 20 meter

Answer:

wavelength= velocity

= 120/6= 20 meter

Explanation:

i) The velocity of the particle at 17 sec is 17m/s.

ii) The total distance travelled is 190 m.

iii) The total displacement is -10m.

Distance is the length of any path connecting any two places. As measured along the shortest path between any two points, displacement is the direct distance between them.

The direction is ignored when calculating distance. The direction is accounted for in the displacement calculation.

Since it solely depends on magnitude and not direction, distance is a scalar number. Since displacement varies on both magnitude and direction, it is a vector quantity.

Distance provides specific directions that must be taken when moving from one location to another. Displacement only provides a partial description of the route because it pertains to the quickest way.

Velocity of particle = Slope of the object =Δ \(\frac{y}{x}\)

Velocity = \(\frac{95-10}{20-15}\) = 17m/s

Answer:

The value is \(s = 110.32 \ m\)

Explanation:

From the question we are told that

   The initial velocity is  u=  46.5 m/s

Generally from kinematic equations we have that

     \(v^2 = u^2 + 2as\)

Here  \(a = -g = -9.8 \ m/s^2\)

   The negative sign is because it is moving against gravity

At maximum height v =  0 m/s        

So

     \(0 = (46.5)^2 + 2* (-9.8)s\)

=>   \(s = 110.32 \ m\)

The mass of the airplane is approximately 15.63 slugs.To find the mass of the airplane, we can use the formula: mass = weight / gravitational acceleration. In this case, the weight of the airplane is given as 16,000 lb and the local gravitational acceleration is 32 fps^2.

Using the formula, we can calculate the mass as follows:

mass = 16,000 lb / 32 fps^2

To simplify the calculation, we need to convert the weight from pounds to slugs. Since 1 slug is equal to 32.2 pounds, we divide the weight by 32.2 to obtain the weight in slugs:

weight (in slugs) = 16,000 lb / 32.2 lb/slug

Now we can substitute the weight in slugs into the formula:

mass = weight (in slugs) / gravitational acceleration

mass = (16,000 lb / 32.2 lb/slug) / 32 fps^2

After simplifying the units, we get:

mass = (500 slugs) / (32 fps^2)

mass ≈ 15.63 slugs

Therefore, the mass of the airplane is approximately 15.63 slugs.

The correct option is option (c): In Atrial Tachycardia, the P waves are commonly seen as irregular or have a sawtooth pattern.

Atrial Tachycardia is a condition characterized by a rapid heart rate originating from abnormal electrical activity in the atria of the heart. In this condition, the P waves, which represent the electrical activity generated by the atria, can exhibit certain characteristic patterns. One common finding in Atrial Tachycardia is irregular P waves.

The irregularity occurs because the electrical signals responsible for generating the P waves are not originating from the sinus node, the normal pacemaker of the heart, resulting in a lack of consistent rhythm. Another common presentation of P waves in Atrial Tachycardia is a sawtooth pattern, known as "sawtooth flutter waves."

These waves have a distinct appearance, resembling a series of sharp peaks and valleys, which can be observed on an electrocardiogram (ECG). The irregular or sawtooth P waves in Atrial Tachycardia can help differentiate this condition from other types of tachycardia and aid in its diagnosis.

If an object has particles that are moving very slowly, the object's temperature is probably low.

Temperature is a macroscopic property that quantifies the average kinetic energy of particles within a system.

The kinetic energy of an individual particle is related to its speed, as kinetic energy (KE) is given by the equation KE = 1/2 * mv^2, where m is the mass of the particle and v is its velocity.

In a system with particles moving very slowly, it implies that the average speed of the particles is low. This low average speed translates to a lower average kinetic energy for the particles within the system.

Since temperature is a measure of the average kinetic energy, an object with particles moving slowly is likely to have a low temperature.

To understand this concept, consider a solid object at a low temperature. The particles in the object, such as atoms or molecules, have limited thermal energy and move slowly in a localized manner.

The individual particles vibrate or oscillate around their equilibrium positions, but their net displacement or overall motion is minimal.

As the temperature increases, the average kinetic energy of the particles also increases. This leads to more vigorous and rapid motion of the particles. In a gas, for example, higher temperatures result in faster random motion of the gas molecules.

Therefore, if an object has particles that are moving very slowly, it is an indication that the average kinetic energy and, consequently, the temperature of the object are low.

Explanation:

The number of the solenoid's turns (N) can be found as follows:

\( N = \frac{L*I}{\phi_{B}} \)    (1)

Where:

L: is the self-inductance of the solenoid

I: is the current = 1.40 A

\(\phi_{B}\): is the magnetic flux = 0.00308 Wb      

The self-inductance of the solenoid (L) is:

\( L = \frac{|\epsilon|}{|dI/dt|} \)   (2)

Answer:

Plural cerebrums cerebra The largest part of the vertebrate brain, filling most of the skull and consisting of two cerebral hemispheres divided by a deep groove and joined by the corpus callosum, a transverse band of nerve fibers. The cerebrum processes complex sensory information and controls voluntary muscle activity.

Explanation:

The correct statements are: [1] If the absorbance band of an interferent can be blocked by the slit while still passing the absorbance band of the analyte, [3] If narrowing the slit causes the light band passed to go from polychromatic to monochromatic light, [4] If the bandwidth of the light passed by the slit includes some of the baseline.

By adjusting the slit width on a monochromator, it is possible to selectively block certain absorbance bands while allowing others to pass through. This can be useful in eliminating interference from other substances in the sample.

Narrowing the slit width reduces the range of wavelengths that can pass through, resulting in a more monochromatic light. This can enhance the sensitivity of absorbance measurements by reducing background noise.

If the bandwidth of the light passed by the slit includes some of the baseline, it can lead to inaccuracies in absorbance measurements. Narrowing the slit width helps to minimize the inclusion of baseline noise, improving the sensitivity of the measurement.

Explanation:

Use the equation: acceleration (a) = change in velocity (v – u) / time taken (t)

Explanation:

The horizontal velocity of the ball remains constant and unchanged.

When you throw a ball horizontally with a speed of 3 m/s, its horizontal velocity will be 3 m/s, even after 2 seconds have passed. In this problem, neglecting the force of air resistance means that there will be no external forces acting on the ball that would alter its horizontal velocity.

Since velocity is a vector quantity (having both magnitude and direction), the horizontal velocity of the ball remains constant at 3 m/s in the horizontal direction.

Now, if we consider the vertical motion of the ball, it will be subject to the force of gravity, which will cause it to accelerate downwards at a rate of 9.8 m/s^2 (the acceleration due to gravity near the surface of the Earth).

Assuming that there is no friction or other forms of energy loss in the system, the change in kinetic energy of the block after it is released from rest and has traveled a distance of a2 can be calculated using the conservation of energy principle, which states that the total mechanical energy of a system remains constant.

At the starting point, all of the potential energy stored in the spring is converted to kinetic energy as the block is released from rest.Therefore, at the starting point, the kinetic energy of the block is zero and the potential energy stored in the spring is u₀.

When the block has traveled a distance of a2, it has reached a point where it has no potential energy left, as the spring has returned to its original length.

At this point, all of the energy is in the form of kinetic energy. Therefore, the kinetic energy of the block when it has traveled a distance of a2 is given by:

K = U₀

where K is the kinetic energy of the block and U₀ is the initial potential energy stored in the spring.

The change in kinetic energy of the block as it travels from the starting point to a distance of a2 can be calculated by subtracting the initial kinetic energy from the final kinetic energy:

ΔK = K2 - K1

= U₀ - 0

= U₀

Therefore, the change in kinetic energy of the block after it is released from rest and has traveled a distance of a2 is equal to the initial potential energy stored in the spring, which is U₀.

Explanation:

The minimum tension in the vertical wire must be 14.7 N to support the 1.5 kg picture.(the wire is supporting the picture in a vertical position) is 14.7 N.

To determine the minimum tension of a single vertical wire required to support a 1.5 kg picture, we need to consider the gravitational force acting on the picture.

The force of gravity acting on the picture can be calculated using the equation: F(gravity) = m * g,

where F(gravity) is the force of gravity, m is the mass of the picture, and g is the acceleration due to gravity (approximately 9.8 m/s²).

Substituting the given mass of the picture, m = 1.5 kg, into the equation, we have:

F(gravity) = 1.5 kg * 9.8 m/s² = 14.7 N.

Since the wire is supporting the picture in a vertical position, the tension in the wire must be equal to the force of gravity to maintain equilibrium.

Therefore, the minimum tension in the vertical wire must be 14.7 N to support the 1.5 kg picture is 14.7 N.
