Explanation:

Answer:

453.25 MJ

Explanation:

The formula to find kinetic energy is :

\(E_{k} = \frac{1}{2} X m X v^{2}\)

E.k = ?

m = 0.56kg

v = 25mi./s which needs to be converted into metres per second

1mi./s= 1609.34m/s

25 mi./s = 40233.6 m/s.

E.k. = 0.5 × 0.56 × 40233.6²

e.k = 453247919.3J

E.k.= 453.25 MJ

Answer:

a = 5m/s^2

Explanation:

Vi=0 m/s

ΔY=10m

Δt=2s

find acceleration

With the givens and the acceleration being the only one missing, we can safely use the Δy = Vi Δt + 1/2 a (Δt)^2 formula

Plug it in and we get:

10 = 0 x 2 + 1/2 a (2)^2

10 = a2

10/2 = a 2/2

a = 5 m/s^2

Distance divided by time so 1246/156=7.98717948718

Answer:

26897.3 m

Explanation:

1 km = 1000 m

1 cm = 0.01 m

so the calculation will be

25873 m + 1024 m + 0.03 m= 26897.3 m

The sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)  would be 26897.0 meters.

In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.

As given in the problem we have to Calculate the following sum and express the answer in meters, by Following the rules for significant figures,

(25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)

1 kilometers = 1000 meters

1 meter =100 centimeters

(25.873 ×1000×100) + (1024×100 ) + (3.0 centimeters)

                = 26897.03 centimeters

Thus ,the sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)  would be 26897.0 meters.

Inducing magnetic properties on a substance means you are aligning the electrons to spin in the same direction, 2nd option.

The magnetic intensity is the magnetic field produced solely by the electric current flowing in a solenoid. The magnetic property of a material is induced by an external magnetic field. When a material is exposed to an external magnetic field, it becomes magnetized.

A strong magnetic field is produced when the majority of electrons in an atom spin in the same direction. The magnetic field's direction is determined by the direction of electron spin.

Answer:

distance divided by time is the speed. Your welcome

Answer:

51 miles/hour

Explanation:

Talia is on a road trip with some friends. in the first 2 hours, they travel 100 miles. then they hit traffic and go only 30 miles in the next hour. the last hour of their trip, they drive 75 miles. calculate the average speed of talia’s car during the trip. give your answer to the nearest whole number.

The average speed would be 51 miles/hour.

The average speed of a moving object is defined as the total distance traveled relative to the total time taken fro the journey. Mathematically, it is given as:

  total distance traveled/total time taken.

In this case;

Total distance traveled = 100 + 30 + 75 = 205 miles

Total time taken = 2 + 1 + 1 = 4 hours

Therefore;

Average speed = 205/4 = 51.25 miles/hour

To the nearest whole number = 51 miles/hour

To determine the velocity at which a 300 W motor will pull a mass when applying a force of 13.9 N, we need to consider the relationship between power, force, and velocity.

Power (P) is defined as the rate at which work is done or energy is transferred. It can be calculated using the formula:

P = F * v,

where P is power, F is force, and v is velocity.

Given that the power of the motor is 300 W and the force applied is 13.9 N, we can rearrange the formula to solve for velocity:

v = P / F.

Substituting the given values, we have:

v = 300 W / 13.9 N.

Calculating this expression gives us the velocity at which the motor will pull the mass.

v = 21.58 m/s.

Therefore, the velocity at which the 300 W motor will pull the mass when applying a force of 13.9 N is approximately 21.58 m/s.

Based on the decision tree analysis, the most appropriate decision for the company is to build a medium-sized supermarket with an expected net present value of $600,000.

To determine the most appropriate decision for the supermarket operator, we will analyze the situation using a decision tree. Here's a step-by-step explanation:

1. Calculate the expected net present value (NPV) for each scenario:

Medium-sized supermarket:

- Average demand: NPV = $600,000 (no reason to expand)

Large-sized supermarket:

- Average demand:

- Do nothing: NPV = $100,000

- Stimulate demand through advertising:

- Unfavorable response (20% chance): NPV = -$20,000

- Favorable response (80% chance): NPV = $320,000

- Expected NPV = (0.2 * -$20,000) + (0.8 * $320,000)

                           = $244,000

- Favorable demand:

 - Maintain size: NPV = $623,000

 - Expand:

   - 75% chance of $330,000

   - 25% chance of $610,000

   - Expected NPV = (0.75 * $330,000) + (0.25 * $610,000)

                               = $400,000

2. Calculate expected NPV for each supermarket size:

- Medium-sized: (0.35 * $600,000) + (0.65 * $600,000)

                          = $600,000

- Large-sized: (0.35 * $244,000) + (0.65 * max($623,000, $400,000))

                     = $527,350

3. Compare the expected NPVs:

- Medium-sized: $600,000

- Large-sized: $527,350

Based on the decision tree analysis, the most appropriate decision for the company is to build a medium-sized supermarket with an expected net present value of $600,000.

The Uranus have 13 faint rings and 27 small moons in the solar system.

Uranus, the third-largest planet in our solar system and the seventh from the Sun, is incredibly chilly and windy. The ice giant spins at a nearly 90-degree angle from the axis of its orbit, encircled by 13 foggy rings and 27 tiny moons. One of the two frost giants in the outer solar system is Uranus (the other is Neptune). A heated, dense fluid comprised of the "icy" substances water, methane, and ammonia made up the vast majority (80% or more) of the planet's mass.

The age of Uranus' rings is predicted to be less than 600 million years, considering them extremely juvenile. The collisional fragmentation of several former moons that ringed the planets resulted to the Uranian ring system.

a 0.75 kg projectile has been shot straight up with an initial speed of 18m/s. Then 16.2 m high would it go if there were no air friction.

An object which  is propelled by the application of an external force and as a result then moves freely while being affected by the gravity and air resistance is termed to as a projectile. Projectiles are often used in sports and warfare, despite the fact that any item traveling through space is a basically a projectile.

To find  how high would it go if there were no air friction we will use the following

ΔKE=PE

1/2mu^2-1/2mv^2=mgh

given 1/2mu^2= 1/2*0.75*18^2

1/2mv^2=0m/s

11.The time at 75° East longitude would be 1 hour and 20 minutes behind. 12.The time at 135° degrees East longitude would be 4 hours ahead. and 13. the time in Lima, Peru (15° South latitude, 75° West longitude) would also be 9:30 AM.

At 2:00 AM at 90° East longitude, the time at 75° East longitude would be 1 hour and 20 minutes behind. This is because for every 15 degrees of longitude, there is a time difference of approximately 1 hour. Since the two longitudes in question have a difference of 15 degrees, we can divide this by 15 to calculate the time difference.

If it is 8:00 PM at 15° East longitude, the time at 135° East longitude would be 4 hours ahead. Similarly, for every 15 degrees of longitude, there is an approximate time difference of 1 hour. Since the two longitudes in question have a difference of 120 degrees, we can divide this by 15 to calculate the time difference.

There is a 7-hour difference** between 105° West longitude and the Prime Meridian (0° longitude). The Prime Meridian, passing through Greenwich, England, serves as the reference point for determining time zones. As one moves westward from the Prime Meridian, each 15 degrees of longitude corresponds to a time difference of approximately 1 hour. Therefore, the time at 105° West longitude would be 7 hours behind the time at the Prime Meridian.

If it is 9:30 AM in New York (41° North latitude, 75° West longitude), the time in Lima, Peru (15° South latitude, 75° West longitude) would also be 9:30 AM. The latitude does not affect the time difference between the two locations. However, since both locations have the same longitude (75° West), they would experience the same local time. The time difference between different latitudes is primarily significant for determining time zones rather than the actual time within a specific time zone.
