Answer:

Throwing a penny off the Empire State Building wouldn't kill someone. A penny only weighs about a gram and it tumbles as it falls. Because of the tumbling and the lightweight, there's so much air resistance that the penny never really gathers that much speed before it hits its terminal velocity. A gram of weight traveling at a relatively slow speed might hurt a little if it hit you on the head, but it's not going to kill you.

It is more likely that the storm you observed, which passed over you after an hour, was a mesoscale convective system (MCS) rather than an air mass thunderstorm.

Air mass thunderstorms typically form and dissipate within the boundaries of a single air mass. They are generally short-lived and do not typically travel large distances. Therefore, it is less likely for an air mass thunderstorm to travel from a location far to the west to your current location within just an hour.

On the other hand, mesoscale convective systems are larger-scale weather systems that can cover hundreds of miles and persist for several hours or even longer. They often have organized structures, such as squall lines or clusters of thunderstorms, and can move over significant distances. It is more plausible for a mesoscale convective system to travel from a distant location to your area within the span of an hour.

Considering the time and distance covered, the fact that the storm passed over you after an hour suggests that it was likely a mesoscale convective system.

The net force on an object is zero that is pulled with forces of 80 newtons to the right and 80 newtons to the left.

Net force is equal to sum of all the force acting on a body.

The formula for net force if n force are acting on it:

                       \(F_{net}=F_{1}+ F_{2}+F_{3}.....F_{n}\)

In this case the two forces are equal but opposite in direction.

Putting the values in the formula

\(F_{net} = 80+(-80)\) (since forces are equal but opposite)

\(F_{net}= 0\)

So the net force acting on the object is zero because the forces are equal and opposite.

The probability of stopping at a traffic light is about 47.22%.

With 10 traffic lights, expect to be stopped for approximately 5 minutes and 45 seconds along the main street.

(a) To calculate the probability of stopping at a particular traffic light, we need to consider the cycle time of the traffic lights. The cycle time is the total time taken for one complete sequence of green, amber, and red signals. In this case, the cycle time is 55 + 17 + 48 = 120 seconds.

The probability of stopping at a particular traffic light can be calculated by dividing the red signal duration by the cycle time. Therefore, the probability is 48/120 = 0.4 or 40%.

However, in California, no one stops on amber, so we need to exclude the amber duration from the calculation. Therefore, the probability becomes 48/(55 + 48) ≈ 0.4722 or 47.22%.

(b) If there are 10 traffic lights on the main street, we can calculate the expected amount of time spent stopped at traffic lights by multiplying the probability of stopping at each traffic light by the average duration of being stopped.

The average duration of being stopped at a traffic light is the sum of the red signal duration and half of the amber signal duration. So, the average duration is (48 + 17/2) = 56.5 seconds. To find the expected amount of time stopped at traffic lights, we multiply the average duration by the number of traffic lights: 56.5 seconds * 10 = 565 seconds.

Therefore, if you drive all the way down the main street, the expected amount of time you are likely to be stopped at traffic lights is approximately 565 seconds, which is equivalent to 5 minutes and 45 seconds.

The specific latent heat of vaporization of water is 2300 kj/kg.

What is the specific latent heat of vapourization?

Specific latent heat of vapourization is the quantity of heat required to convert unit mass of a substance from liquid to vapour state without change of temperature.

We have...

Q = heat energy = 69 kj

m = mass = 0.030 kg

L = Specific heat

The formula is given by:

Q = mL

L = Q / m

L = 69 / 0.030

L = 2300 kj / kg

Answer:Food contains chemical potential energy. As our bodies digest it, the stored energy is converted into energy for us to move and grow.

Explanation:

Because chemical energy is held in the molecular bonds of food, it has potential energy.

The primary source of potential energy in food is either the eating of other organisms that have undergone photosynthesis or the photosynthesis process that occurs in plants.

Chloroplasts, specialized organelles found in plants, contain the pigment chlorophyll and are responsible for photosynthesis. When sunlight is absorbed by chlorophyll, it transforms carbon dioxide from the atmosphere and water from the soil into glucose, a type of sugar, and oxygen. Photosynthesis is the name given to this process.

Energy transfer in the food chain: When animals eat plants or other animals (herbivores or carnivores), they acquire the energy that was originally contained in the glucose molecules that the plants created.

Chemical bonds and potential energy: The chemical bonds that connect the atoms in organic compounds like proteins, lipids, and glucose allow for the storage of energy. Because these connections can be broken by chemical processes, which release energy in the process, they can store potential energy.

The potential energy in food is eventually transformed into kinetic energy (energy of motion) and other forms of energy that fuel our daily activities and maintain the health of our bodies.

Hence, Because chemical energy is held in the molecular bonds of food, it has potential energy.

A lens with a longer focal length will have a narrower angle of view, while a lens with a shorter focal length will have a wider angle of view. The focal length of a lens also affects the magnification and focus of the subject in an image.

Focal length is the distance between the optical centre of a lens and the image sensor of a camera. It can be measured in millimetres and is used to determine the angle of view of the lens.

A) The focal length of the second lens can be calculated using the lens equation: 1/f2 = 1/f1 + 1/d, where f1 is the focal length of the first lens (10 cm), d is the distance between the two lenses (10 cm), and f2 is the focal length of the second lens.

(b) The formula M = -d2/d1 can be used to compute the system's overall magnification.

Where d1 is the object's (15 cm) distance from the first lens and d2 is the image's (0 cm). M = 3 is obtained by solving for M. (c) The finished picture is accurate, erect, and enlarged.

Answer:

The star's luminosity rises above its previous level. Because it is so cool, the surface will be red, and it will be much farther away from the center than it was during the earlier stages of star evolution. Despite its lower surface temperature, the red giant has a large surface area, which makes it very luminous.

The largest force in this scenario is the propulsion force.

As the boat passes out of the port and accelerates, one force becomes larger than the other forces. To determine which force is the largest, we need to consider the different forces acting on the boat.

One of the main forces acting on the boat is the propulsion force provided by the boat's engine. This force propels the boat forward and is responsible for its acceleration. As the boat accelerates, the propulsion force increases to overcome the resistance forces such as friction with the water and air resistance.

Therefore, the largest force in this scenario is the propulsion force. It is greater than the resistance forces acting on the boat. This allows the boat to overcome these resistance forces and accelerate forward.

In summary, as the boat passes out of the port and accelerates, the propulsion force provided by the boat's engine becomes the largest force, enabling the boat to overcome the resistance forces and move forward.

Coulomb's law is a fundamental principle in electrostatics that describes the interaction between charged objects. This relationship can be described mathematically as: F=k(q1q2)/d^2, where k is a constant of proportionality, q1 and q2 are the magnitudes of the charges, and d is the distance between the charges.

It states that the force between two point charges is proportional to the magnitude of each charge and inversely proportional to the square of the distance between them.

Test charges are used to determine the magnitude and direction of the force acting on a charged object. They are chosen to be small enough that their presence does not significantly alter the original charges, so that Coulomb's law can be accurately applied to the system. By carefully measuring the force acting on the test charges, the magnitude of the original charges can be determined. This is known as the method of test charges and is an important tool in understanding the behavior of charged objects and their interactions with each other.
