If the elevator is in the upward direction, the force that Yolanda exerts on the floor of the elevator is 81.792 N.

The force that Yolanda exerts on the floor of the elevator can be calculated using Newton's second law of motion, which states that force is equal to mass times acceleration:

force = mass x acceleration

In this case, Yolanda's mass is 38.4 kg, and the upward acceleration of the elevator is 2.13 m/s². So, we can plug these values into the formula:

force = 38.4 kg x 2.13 m/s²

force = 81.792 N

Since the elevator is accelerating upwards, the force that Yolanda exerts on the floor of the elevator is also upwards, so the answer is positive.

The more the kinetic energy of the object attached, more will be the maximum potential energy of the spring. Similarly, if object is hanging in vertical direction, maximum potential energy of the spring will be more if gravitational potential energy is high.

The spring potential energy depends on the kinetic energy and the gravitational potential energy of the object in the following way:

When an object is lifted to a certain height, it gains potential energy, which is referred to as gravitational potential energy. When an object is in motion, it possesses kinetic energy. When an object is compressed or stretched, it acquires potential energy, which is referred to as spring potential energy. Spring potential energy is the energy saved in the compressed or extended state of the spring. When the spring is no longer extended or compressed, it is released and the potential energy is transformed into kinetic energy. When the spring is compressed, its potential energy is at its maximum. When the spring is fully extended, the potential energy is at its minimum. When a force acts on the spring, it gains kinetic energy, which is transformed into spring potential energy after a certain distance.

Spring potential energy formula: Elastic potential energy = (1/2) kx²

The activity reading at 6 meters from the source as observed by the technologist will be  5mR/hr

The activity reading at 6 meters from the source can be calculated using the inverse square law, which states that the radiation intensity is inversely proportional to the square of the distance from the source. Therefore, the activity reading at 6 meters from the source can be calculated as follows:

Activity at 6m = (Distance at 1st measurement / Distance at 2nd measurement)² x Activity at 2m

Activity at 6m = (2m / 6m)² x 45mR/hr

Activity at 6m = (1/9) x 45mR/hr

Activity at 6m = 5mR/hr

Therefore, the activity reading at 6 meters from the source is 5mR/hr. This calculation demonstrates that as the distance from a radiation source increases, the radiation intensity decreases significantly, which is a fundamental principle in radiation safety.

It is essential to maintain appropriate distances from radiation sources and use appropriate protective equipment to minimize exposure to ionizing radiation.

The Doppler method can be used to estimate the average orbital distance of a planet's orbit by measuring the time it takes for the star's line-of-sight velocity to cycle from peak to peak, and using Newton's version of Kepler's third law. Option c) is correct .

If a planet orbits a star, both of them revolve around their mutual center-of-mass. This center-of-mass is very close to the star's center since stars are much more massive than planets. As a result, if the star and planet orbit each other, they appear to move in small circles or ellipses around a fixed point.In the Doppler method, astronomers observe the motion of a star, which can reveal the presence of an exoplanet.

When a planet orbits a star, the star moves slightly as a result of the gravitational tug of the planet. This motion causes the star's spectrum to shift slightly towards longer wavelengths (redshift) and shorter wavelengths (blueshift) as the star moves away from and towards us respectively. The size of this shift depends on the mass of the planet and its orbital distance from the star.

By measuring the size of these shifts, astronomers can infer the presence of an exoplanet and estimate its mass and orbital distance. Hence option c) Is correct ,

According to the big bang theory, we live in a universe that is made of almost entirely of matter rather than antimatter because of a slight excess of matter over antimatter that occurred during the early universe.

This excess is thought to be due to a process called baryogenesis, which involves the production of baryons (such as protons and neutrons) from an initial state of pure energy during the first fractions of a second after the big bang.

The exact mechanism by which baryogenesis occurred is not well understood, but several possible theories have been proposed, including the idea that it is related to the violation of CP symmetry (which refers to the combination of charge conjugation and parity) in the early universe.

In any case, the slight excess of matter over antimatter meant that when matter and antimatter particles collided and annihilated each other during the early universe, there were more matter particles left over, which eventually led to the formation of the structures we see in the universe today.

Answer: All matter is made up of very small particles called atoms.

Explanation:Atoms are the basic building blocks of ordinary matter

If Dr. Hewitt cuts the broom exactly through its center of gravity, then the weights of the two sides of the broom will be equal.

This is because the center of gravity is the point at which the weight of the object can be considered to be concentrated, and cutting the object at this point would result in two halves of equal weight.

However, it is important to note that if the broom is not perfectly symmetrical, the location of the center of gravity may not be at the exact physical center of the broom. In this case, Dr. Hewitt would need to locate the actual center of gravity of the broom and cut it at that point to achieve equal weights on each side.

Nonetheless, if the broom is cut exactly at its center of gravity, the weights of the two sides of the broom will be equal regardless of its shape or size.

Therefore, if the broom is cut exactly at its center of gravity, each half will have half the total weight of the broom.

Using Ohm's Law, we can find the current in the circuit:

I = V/R

In this case, the resistance is 10 ohms and the voltage is 9V, so we have:

I = 9V / 10 ohms = 0.9 A

Therefore, the current in the circuit is 0.9 A.

2). The voltage in the circuit is 120.05 V.

Using Ohm's Law, we can find the voltage in the circuit:

V = I*R

In this case, the resistance is 35 ohms and the current is 3.43 A, so we have:

V = 3.43 A * 35 ohms = 120.05 V

Therefore, the voltage in the circuit is 120.05 V.

3). To find the resistance of the circuit from the graph, the resistance of the circuit is 2 ohms.

Resistance (R) = Voltage (V) / Current (I)

Since the graph shows a straight line, it means that the resistance of the circuit is constant. We can find the resistance of the circuit by calculating the slope of the line.

Slope = Rise / Run = ΔV / ΔI

Looking at the graph, we can see that the voltage increases by 4V when the current increases by 2A. Therefore:

ΔV = 4V

ΔI = 2A

Slope = ΔV / ΔI = 4V / 2A = 2 ohms

Therefore, the resistance of the circuit is 2 ohms.

4). The current pass through the circuit is [tex]I_{2}[/tex] is 2 A.

We can solve this problem by using the principle of conservation of energy. The total energy provided by the battery is equal to the sum of the energy dissipated by the resistors. Since the resistors are connected in parallel, the voltage across each resistor is the same.

The energy dissipated by a resistor is given by the formula:

E = I^2 x R x t

where E is the energy dissipated, I is the current flowing through the resistor, R is the resistance of the resistor, and t is the time for which the current flows.

For the circuit with resistor R1, the energy dissipated is:

E1 = I x R1 x t

For the circuit with resistor R2, the energy dissipated is:

E2 = I2 x R2 x t

Since the batteries are identical, the total energy provided by the battery is the same for both circuits. Therefore, we have:

E1 + E2 = I x R1 x t + I2 x R2 x t

Substituting the given values, we get:

2 x (30) x t + I2 x (45) x t = 2 x (30 + 45) x t

Simplifying, we get:

60t + 45I2t = 150t

15I2t = 90t

The wheels make 210 revolutions per minute.

The first part of the question is asking for the angular speed of the wheel which is expressed in rad/min. The angular speed is defined as the rate at which an object changes its angle with respect to a fixed point.

The angular speed can be calculated using the formula:ω = v/r Where;ω = angular velocity, v = linear velocity, r = radius of the wheel

Let’s convert the speed given in miles/hour to meters/minute.

The conversion factor for miles to meters is 1 mi = 1609.34 m, and for hours to minutes is 1 hr = 60 min.15 mi/h = 15 × 1609.34 m/60 min = 402.34 m/min

The radius of the wheel is half of the diameter; r = 24/2 = 12 inches.

To convert inches to meters, we multiply by a conversion factor of 0.0254 m/inch.

Therefore; r = 12 × 0.0254 m/inch = 0.3048 m

Now, let’s substitute the values into the angular velocity formula; ω = v/r = 402.34 m/min/0.3048 m = 1319.2 rad/min

To calculate the number of revolutions per minute the wheels make, we can use the formula ;f = ω/2π Where; f = frequencyω = angular velocity = 1319.2 rad/min2π = 6.28f = 1319.2/6.28 = 210 revolutions/min

As the embryo grows, its cells divide and become more specialized, and it increases in size, causing the seed coat to become too small to contain the growing plant.

The embryo puts pressure on the seed coat until it splits and the plant emerges. This force is due to the pressure generated by the expanding plant embryo, not any outside force. The embryo contains hormones, proteins, and other substances that cause cells to divide and specialize, which increases its size and puts pressure on the seed coat.

As it does this, the outer layers of the seed coat split, allowing the embryo to emerge. This force is not caused by gravity or any other external force. In conclusion, the force that allows the sunflower seed to emerge from its seed coat is generated by the pressure from the growing embryo inside the seed coat, not any outside force.
