The squirrel has a good luck ,Car gets stopped just 1m away from the squirrel .

Explanation:

According to the Question

A squirrel runs out in front of a car moving at +20m/s ( initial speed u) . The driver slams on the brakes and begins decreasing at -8m/s² ( here the acceleration is acting in opposite directions of motion a )

When Squirrel was 26 metres ( Distance from the car initially )

Using Kinematic Equation

On substituting the value we obtain

➥ 0² = 20² + 2 × -8 × s

➥ 0 = 400 - 16 × s

➥ -400 = -16 × s

➥ 400/16 = s

➥ 25 = s

So, the squirrel is 25 metres from the car .

Answer:

Your answer is F = 2280 N

Explanation:

The formula for force is \(F=ma\). Given this formula, \(1520\) × \(1.5\) \(= 2280\)

If a musical note has a frequency of 212 Hz and a wavelength of 425 m, its velocity is 90.1 m/s.

The speed of sound is a relationship between frequency and wavelength, mathematically represented as follows:

speed = frequency x wavelength

In this case, the frequency is 212 Hz and the wavelength is 0.425 m. Plugging these values into the equation gives:

speed = frequency x wavelength

speed = 212 Hz x 0.425 m

speed = 90.1 m/s

Therefore, we can affirm that the the speed of the sound of the musical note is 90.1 m/s.

Given :

Velocity of bullet, \(v_b=300\ m/s\).

Mass of bullet, m = 0.005 kg.

Mass of rifle, M = 5 kg.

To Find :

The recoil velocity of the rifle.

Solution :

Since, their is no external force is acting.

So, momentum of the system will be conserved :

Initial momentum = Final momentum

m(0) + M(0) = m(300) + Mv

\(v=-\dfrac{300m}{M}\\\\v=-\dfrac{300\times 0.005}{5}\\\\v=-0.3 \ m/s\)

Therefore, recoil velocity of the rifle is 0.3 m/s.

Hence, this is the required solution.

The kinetic energy of the crate as it reaches the lower surface is 80 J

Kinetic energy is the energy possed by an object in motion. Mathematically, the kinetic energy can be expressed as follow:

The diameter of the image formed by the objective is approximately 2.85 cm. This can be calculated using the formula: diameter = (focal length of the objective) * (angle subtended by the object).

In this case, diameter = 95 cm * 0.009 rad = 0.855 cm, but since the objective forms a real image that is magnified by the eyepiece, the final diameter is larger and typically considered as 2 to 3 times the diameter of the exit pupil, giving a result of approximately 2.85 cm.

The formula used to calculate the diameter of the image formed by the objective is based on the thin lens equation: magnification = (focal length of the objective) / (focal length of the eyepiece). In a simple telescope, the objective lens forms a real, inverted image of the moon, which is then magnified by the eyepiece to be observed. The angle subtended by the moon can be used to calculate the diameter of the image formed by the objective. However, it is important to note that the final diameter of the image is typically larger due to the magnification provided by the eyepiece. The value of 2.85 cm is an estimate and may vary depending on factors such as the specific telescope design and observer preferences.

Answer:

The length of the incline is 3.504 meters.

Explanation:

Let suppose that Julietta's ball decelerates uniformly, then we determine the length of the incline is determined by the following equation of motion:

\(\Delta s = v_{o}\cdot t +\frac{1}{2}\cdot a \cdot t^{2}\) (Eq. 1)

Where:

\(\Delta s\) - Length of the incline, measured in meters.

\(v_{o}\) - Initial speed of the ball, measured in meters per second.

\(a\) - Aceleration of the ball, measured in meters per square second.

\(t\) - Time, measured in second.

If we know that \(v_{o} = 2.95\,\frac{m}{s}\), \(t = 1.54\,s\) and \(a = -0.876\,\frac{m}{s^{2}}\), then the length of the incline is:

\(\Delta s = \left(2.95\,\frac{m}{s} \right)\cdot (1.54\,s)+\frac{1}{2}\cdot \left(-0.876\,\frac{m}{s^{2}} \right) \cdot (1.54\,s)^{2}\)

\(\Delta s = 3.504\,m\)

The length of the incline is 3.504 meters.

When a component is used to perform the function of stop in a control circuit, it will generally be a normally closed component and be connected in parallel with the motor starter coil. Control circuits are an essential component of industrial automation.

They manage the flow of power and information to devices and systems that need to be automated. They control a wide range of machinery and processes, from packaging and filling machines to temperature and pressure control systems. Control circuits require a variety of components that can be used to create the necessary logic and electrical paths.

One of the essential components of control circuits is the stop function. The stop function is necessary to halt the machine's operation in an emergency or planned maintenance. The stop function is accomplished by using a normally closed component, which means the circuit is closed by default.

When the stop function is initiated, the component opens the circuit, stopping the machine. The component is typically connected in parallel with the motor starter coil, which ensures that the motor stops running immediately after the circuit is opened.

The given statement "vectors can be added together using the rules of algebra" is true.

A quantity or phenomena with independent qualities for both size and direction is called a vector. The word can also refer to a quantity's mathematical or geometrical representation. Velocity, momentum, force, electromagnetic fields, and weight are a few examples of vectors in nature.

When performing vector addition, you simply add the corresponding components of each vector together.

For example, if you have two vectors A = (a₁, a₂) and B = (b₁, b₂),

their sum C = A + B would be:

C = (a₁ + b₁, a₂ + b₂)

Any two vectors are not subject to the vector addition rule. Only when two vectors of the same kind and nature are they added.
