The elastic potential energy stored in the compressed spring is determined as 11.6 J.

The elastic potential energy of the spring is the energy stored in the spring and the magnitude is calculated as follows;

U = ( ¹/₂kx² )

where;

The given parameters include the following;

the spring constant, k = 580 N/m

the extension of the spring, x = 0.2 m

Substitute the given parameters and solve for the elastic potential energy stored in the spring based on the compression produced by the two blocks.

U = ( ¹/₂kx² )

U = ( ¹/₂ ( 580 N/m ) ( 0.2 m )² )

U = 11.6 J

Answer:

When light enters from air to water i.e. it is moving from rarer to denser medium, it changes its original path as there is a change of speed of light and deflects itself towards the normal. This is known as the refraction of light and this is why a pencil in a cup of water looks as if it is broken and larger.

Major League Baseball games last an average of 190.885 minutes with a standard deviation that was not specified in the question. The standard deviation is a measure of how much the data deviates from the mean or average.

It can be used to determine the spread of the data and how closely the individual values cluster around the mean. Without the standard deviation, it is difficult to make any further conclusions about the duration of MLB games.

4.266 m is the radius of the circular path the electron follows

Electron's speed = 7.50 × 10⁶ m/s

Magnetic field, B = 1 × 10⁻⁵ T

Electron's mass. m = 9.11 × 10⁻³¹

Charge of electron, q = 1.6 × 10⁻¹⁹

We know the relation of radius of curvature, = 4.266 m

Every point on a circle has a curvature that is equal to the reciprocal of the radius; for other curves (and straight lines, which can be thought of as circles of infinite radius), the curvature is equal to the reciprocal of the radius of the circle that at that point most closely approximates the curve.

The curvature's reciprocal, R, is the radius of curvature in differential geometry. It is equal to the radius of the circular arc that, at that moment, most closely resembles the curve for a curve. The radius of curvature for surfaces is the diameter of a circle that, individually or in combination, best fits a normal section.

Explanation:

The 80.50 dollars would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 32.0 mi/gal.

To convert a given amount expressed in terms of unit miles to unit kilometres, use the miles to km formula. There are 1.6 kilometres in a mile.

The currency and monetary unit of the European Union is the euro, denoted by the sign €. Prior to being released as currency notes and coins in 2002, it started out as a noncash monetary unit in 1999. The national currencies of participating EU members and certain non-EU states were replaced by the euro.

Calculation:

Total km so 113km per day for 7 days is 791 km.

Then we change 791km to miles = 491.211 miles.

Since the car is 32 miles per gallon we divide 491.211/32= 15.35 gallons.

We change gallons to liters so we have 15.35gal x 3.785L= 58.09 L

At 1.10 euros per liter is 58.09 x 1.10 = 63.89 euros.

Assume 1 euro =- 1.26 dollars

Change euros to dollars 63.89 x 1.26 = 80.50 dollars.

Answer:

8165.138kg/cubic meter

Explanation:

Pressure= 80100 Pascal.= 1N/m^2

Height=10.2 meters

density of the fluid in kg/cubic meter= ?

g=acceleration due to gravity= 9.81m/s^2

The pressure of a system can be calculated using the expression below

P = ρ g h

Where

p =pressure,

h =depth of the liquid,

ρ = density of the liquid,

g = acceleration due to gravity.

If we substitute those values we have

80100 1N/m^2= ρ × 9.81m/s^2

ρ= 80100/9.81

ρ=8165.138kg/cubic meter

Hence, the density of the fluid in kg/cubic meter is 8165.138kg/cubic meter

Answer:

Option D. ²³⁹₉₃Np

Explanation:

Let the unknown be ʸₓA.

Thus, the equation becomes:

²³⁹₉₂U —> ⁰₋₁e + ʸₓA

Next, we shall determine the x, y and A. This can be obtained as follow:

92 = –1 + x

Collect like terms

92 + 1 = x

93 = x

x = 93

239 = 0 + y

239 = y

y = 239

ʸₓA => ²³⁹₉₃A => ²³⁹₉₃Np

Thus, the complete equation is:

²³⁹₉₂U —> ⁰₋₁e + ²³⁹₉₃Np

The female whale is approximately 3,000 meters away from the male whale.

To calculate the distance between the male and female blue whales, we can use the formula:

Distance = (Speed of sound in water × Time) / 2

Given that the speed of sound in water is approximately 1,500 m/s and the time taken for the sound to return is 4 seconds, we can substitute these values into the formula:

Distance = (1,500 m/s × 4 s) / 2

Simplifying the equation:

Distance = (6,000 m) / 2

Distance = 3,000 m

These Milky Way companion galaxies are easily visible from dark locations in the Southern Hemisphere. Prime examples of erratic galaxies are the Large and Small Magellanic clouds (left and right, respectively).

In comparison to a rich cluster, the poor cluster typically has a slightly more erratic shape. A number of smaller galaxies orbit each major spiral. The Small and Large Magellanic clouds are the two most well-known examples of atypical galaxies.

When two galaxies collide, irregular galaxies frequently result. This unusual Cartwheel Galaxy was created when a tiny galaxy slid through the centre of a massive spiral galaxy.

The roller coaster used 468KJ of potential energy that was then transformed to thermal energy.

visualise a roller coaster drive that converts potential energy to thermal energy The roller coaster's descent generates kinetic energy. The bottom of the roller coaster's track is where the highest kinetic energy is produced. As the object starts to rise, the kinetic energy turns into potential energy.

A roller coaster moves because potential energy is transformed into kinetic energy. As the roller coaster vehicles are driven to the top of the first hill, their potential energy increases. The cars fall, converting potential energy into kinetic energy.

The roller coaster ride transforms the stored potential energy at a height of 135m into kinetic and thermal energy.

P.E = K.E final + Thermal energy

Answer:

The angle at which a projectile is launched is important because it determines the initial velocity of the projectile and the direction in which it will travel. The angle also affects the projectile's trajectory, or the path that it follows through the air. The steeper the launch angle, the higher the projectile will go and the farther it will travel horizontally. A shallower launch angle will result in a flatter trajectory that does not go as high or travel as far. Therefore, the angle at which a projectile is launched is a key factor in determining how far and how high it will go.

Explanation:

The angle is important when launching projectile motion because it in the calculation of the maximum height, range and time of flight, angle of launching  is as important as the magnitude of initial velocity.

When a particle is hurled obliquely near the surface of the earth, it travels along a curved path while accelerating continuously in the direction of the planet's center (we assume the particle stays close to the surface of the globe). Such a particle's motion is known as projectile motion, and its route is referred to as a projectile.
