Kinetic energy is the energy of motion, observable as the movement of an object or subatomic particle. Every moving object and particle have kinetic energy. A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy at work

Answer:

Magnetism is a physical phenomenon that manifests itself in a force acting between magnets or other magnetized or magnetisable objects, and a force acting on moving electric charges, such as in current-carrying cables. The force action takes place by means of a magnetic field, which is generated by the objects themselves or otherwise. There are natural and artificial magnets. All magnets have two poles called the north pole and the south pole. The north pole of one magnet repels the north pole of another magnet and attracts the south pole of another magnet; the same with south poles.  

The speed of the water jet emerging from the nozzle with a water density of 1000 kg/m³ is 30.107 m/s.

Speed can be defined as the rate of change in the distance of an object. It is a scalar quantity due to only magnitude and no direction.

Height = 3.3 m

Diameter = 2.03 inch

Gauge pressure = 450.228 kPa

We need to calculate the speed of the water jet emerging from the nozzle

Using Bernoulli's equation,

1/2ρ(Vn² - Vp²) = P gauge - ρgh

(Vn² - Vp²) = (2/P) Pgauge - 2gh

Vn² - (An/ Ap)²Vn² = (2/P) Pgauge - 2gh

Vn² - (rn/ rp)⁴Vn² = (2/P) Pgauge - 2gh

Vn² = \(\sqrt{(2/P) Pgauge - 2gh/ (1- (rn/ rp)^4)}\)

Vn = \(\sqrt{[((2/1000)(450.228 X 10^3)) - 2 X 9.8 X 3.3]/ 1 - (1.01/ 1.91)^4}\)

Vn = \(\sqrt{(2 X 450.228 - 64.68)/ 1- (1.04/ 13.30)}\)

Vn = \(\sqrt{(900.45 - 64.68)/ (13.30- 1.04)/13.30}\)

Vn = \(\sqrt{(835.776)/ (12.26/ 13.30)}\)

Vn = \(\sqrt{(835.776)/ 0.922}\)

Vn = \(\sqrt{906.48}\)

Vn = 30.107 m/s

The front of the truck is designed to crumple during a collision to absorb the impact energy, slow down the collision, and protect the well-being of the passengers. This design feature helps increase the collision time, reduce the forces acting on the passengers, and minimize the risk of severe injuries.

Danica observes a collision between two vehicles. She sees a large truck driving down the road. It strikes a small car parked at the side of the road. On colliding, the truck applies a force on the stationary car, and the stationary car applies an opposite force on the truck. The front of the truck is designed to crumple in order to absorb the impact energy and slow down the collision , which protects the well-being of the passengers.

During a collision, the principle of Newton's third law of motion comes into play. According to this law, for every action, there is an equal and opposite reaction. In the case of the collision between the truck and the car, the truck exerts a force on the car, pushing it forward, while simultaneously experiencing an equal and opposite force from the car.

The purpose of designing the front of the truck to crumple is to increase the collision time and absorb the kinetic energy. When the truck collides with the stationary car, the front of the truck deforms, crumples, and absorbs a significant amount of the impact energy. This process increases the time over which the collision occurs, reducing the forces acting on the passengers and minimizing the risk of severe injuries.

By allowing the truck to crumple, the kinetic energy of the collision is transformed into other forms, such as deformation energy and heat. This energy transformation helps protect the passengers by reducing the deceleration forces acting on them. It also helps prevent the transfer of excessive forces to the car's occupants and reduces the likelihood of severe injuries.

Answer:

The length of the spring is 44.92 cm

Explanation:

Hooke's Law

Suppose a spring of constant k and natural length x0. If a force F is applied to the spring and it stretches to a distance x1. Hooke's Law states that:

\(F=k.x\)

Where x is the elongation of the spring:

\(x=x1-x0\)

We are given the characteristics of a spring of x0=31 cm. When a mass of m=8 Kg is hung from the spring, it stretches to x1=36.9 cm. We need to calculate the force of the mass of 8 Kg. It can be done by calculating the weight:

\(F = m.g=8\ Kg\cdot 9.8\ m/s^2\)

\(F=78.4\ N\)

The elongation of the spring is

\(x=36.9\ cm - 31\ cm = 5.9\ cm\)

Converting to meters:

\(x=5.9/100=0.059\ m\)

(a)

From Hooke's Law, we solve for k:

\(\displaystyle k=\frac{F}{x}=\frac{78.4}{0.059}\)

\(k=1,329\ N/m\)

(b) With the value of k, the equation for the spring is:

\(F=1,329.x\)

Now if a weight of F=185 N is hung from the spring, the elongation is:

\(\displaystyle x=\frac{F}{1,329}=\frac{185}{1,329}\)

\(x=0.1392\ m=13.92\ cm\)

Thus, the length of the spring is:

\(x1=xo+x=31\ cm+13.92\ cm=44.92\ cm\)

The length of the spring is 44.92 cm

(a)The spring constant will be 1,329 N/m.

(b)The length of the spring will be 44.92 cm.

Spring constant is defined as the ratio of force per unit displaced length. The spring force is balanced by the weight;

The given data in the problem is;

L₁  is the long spring is hung vertically from a ceiling= 31.0 cm

L₂  = 36.9 cm

m is the mass= 8.00 kg

The net elongation of the spring is

x= 36.9-31 =5.9 cm = 0.059 m

The force acted on the spring due to which the elongation is done;

F=mg

F= 8 × 9.81

F=78.4 n

From the Hooke's law the spring constant is found as;

\(\rm K = \frac{F}{x} \\\\ \rm K = \frac{78.4}{0.059} \\\\ \rm K = 1,329 \ N/m\)

Hence the spring constant will be 1,329 (in N/m).

(b) The length of the spring will be 44.92 cm.

For the  weight of F=185 N is hung from the spring, the elongation is:

\(\rm x= \frac{185}{1,329} \\\\ \rm x=0.10392 m = 13.92 \ cm\)

The length of spring is;

\(\rm x_1 = x_0+x \\\\ \rm x_1 = 31+13.92 \\\\ \rm x_1=44.92\ cm\)

Hence the length of the spring will be 44.92 cm.

The electric potential energy stored in a capacitor is given by the formula:

U = (1/2) * C * V^2

where U is the potential energy in Joules, C is the capacitance in Farads, and V is the voltage across the capacitor in Volts.

In this case, we are given that the capacitor stores 9.40 x 10^-10 C of charge at 50.0 V. However, we are not given the capacitance value. Therefore, we cannot calculate the potential energy directly using the above formula.

To find the capacitance value, we can use the formula:

C = Q / V

where Q is the charge stored in the capacitor and V is the voltage across the capacitor.

Substituting the given values, we get:

C = 9.40 x 10^-10 / 50.0

= 1.88 x 10^-11 F

Now we can use the formula for electric potential energy to find the energy stored in the capacitor:

U = (1/2) * 1.88 x 10^-11 * (50.0)^2

= 4.70 x 10^-8 J

Therefore, the electric potential energy stored in the capacitor is 4.70 x 10^-8 Joules.
