The current flowing through a 60-watt bulb with a voltage supply of 120 volts is calculated using the equation I = P/V, which yields a result of 0.5 amperes.

To calculate the current flowing through a 60-watt bulb given a voltage of 120 volts, we can use Ohm's Law and the power equation. The power equation is P = IV, where P is power in watts, I is current in amperes, and V is voltage in volts.

First, we need to rearrange the equation to solve for the current I. Doing so, we get I = P/V. By substituting the given values, we have I = 60 W / 120 V. Therefore, I = 0.5 A.

The result shows that a current of 0.5 amperes (0.5 A) is flowing through the 60-watt bulb when it is connected to a 120-volt power supply.

Answer:

D

Explanation:

Non-visible radiation is used in medical imaging, such as X-rays and ultrasound, in sterilization and disinfection with UV light, and in commercial applications like detecting metal flaws and preserving food.

Example of Non-Visible Radiation Used in Medical Imaging:

Medical imaging is a major application of non-visible radiation that does not rely on radioisotopes. An example of this is the use of X-ray imaging to view the internal structure of the body, which utilizes X-rays, a form of electromagnetic radiation outside the visible spectrum, to create images of bones and organs. Ultrasound, another non-visible form of radiation, uses high-frequency sound waves to produce images of soft tissues, such as inside a pregnant woman's womb to monitor the developing fetus.

Non-Visible Radiation in Sterilization and Disinfection:

Another use of non-visible radiation is in the field of sterilization and disinfection. Ultraviolet (UV) light is effective at killing microorganisms by causing damage to their DNA. This type of nonionizing radiation is less energetic than ionizing radiation and can be used to sterilize surgical instruments and disinfect water without penetrating the material of the packaging or damaging the cells of human tissue.

Non-Visible Radiation for Pest Control and Food Preservation:

Non-visible radiation is also used commercially, such as using gamma rays from cobalt-60 to detect flaws in metals and to sterilize male flies for pest control. In food preservation, non-visible radiation is applied to kill microorganisms that can spoil food, thus extending its shelf life and reducing the risk of foodborne illnesses without the use of chemical preservatives.

Answer:

b. the smaller object

Explanation:

According to Newton's second law, when a force is applied to an object, it accelerates. This acceleration is proportional to the intensity of the applied force and is inversely proportional to the mass that moves. Therefore, the lower the mass, the greater the acceleration.

Explanation:

The element with electronic configuration The electronic configuration of an element is 1s22s22p63s23p64s1 has a partially filled s-orbital. This is typical of a representative element. In a representative element the highest s-orbital or p-orbital is partially filled.

Answer:

a₂ = 6 m/s²

Explanation:

Conceptual Analysis

We apply Newton's second law:

F=m*a Formula (1)

m: mass  in kilograms (kg)

a: acceleration (m/s²)

F: force in Newtons (N)

Known Data

a₁ = 2 m/s²

m₁= m

m₂= (1/3)m

Problem development

We apply formula (1) for the two conditions given:

F₁ = m₁*a₁ = m*2

F₂ = m₂*a₂= (1/3)m*a₂

F₁ = F₂

m*2 =  (1/3)m*a₂   We divide by m on both sides of the equation

2 = (1/3)*a₂

6 = a₂

a₂ = 6 m/s²

To calculate the velocity of the plane relative to the ground, add up the x and y components of the plane's velocity and the wind velocity. Find the magnitude and direction of the resultant velocity using the Pythagorean theorem and trigonometry.

To calculate the velocity of the plane relative to the ground, we need to consider the vector sum of the plane's velocity and the wind velocity. We can break down the velocity vectors into their x and y components. The plane's velocity is due south, so its x component is 0 km/h and its y component is -600 km/h. The wind velocity is blowing from the southwest, which can be represented as 45 degrees south of west. Its x component is -100*cos(45) km/h and its y component is -100*sin(45) km/h. Now we can add up the x and y components to find the resultant velocity vector. The x component is 0 + (-100*cos(45)) km/h and the y component is -600 + (-100*sin(45)) km/h. Finally, we can find the magnitude and direction of the resultant velocity vector using the Pythagorean theorem and trigonometry. The magnitude is sqrt(x^2 + y^2) km/h and the direction can be found using the arctan(y/x) function.

Answer:

Force due to seat must be equal to the Weight of the student

Explanation:

As we know that the student is sitting on the seat at rest

So here we can say that at this position the student must be at equilibrium position

so we can write force equation for this position of student

vertically downward the net force is due to his/ her weight which is given as

[tex]W = mg[/tex]

now this weight of the student is counter balanced by the the normal force due to seat which is in opposite direction

Now for equilibrium position of the object we will have

[tex]F_n = mg[/tex]

so the seat will push the student upwards by force which is equal to the weight.

The equation relating distance "d" and time "t" is d = 10.56t. This equation represents a direct variation between distance and time, where 10.56 is the constant of variation. The graph of this equation is a straight line passing through points (0,0) and (1.25, 13.2).

The distance "d" you bike varying directly with the amount of time "t" you bike suggests a linear relationship. This can be represented as d = kt, where "k" is the constant of variation, representing the rate you bike per hour. From the provided information, we know that if you bike for 1.25 hours, you travel 13.2 miles. That means k = d/t = 13.2 / 1.25 , which equals 10.56. So the equation relating "d" and "t" is d = 10.56t.

To graph this equation, you would plot time on the x-axis and distance on the y-axis. Begin by plotting a point at (0,0). Then plot a second point at (1.25, 13.2) as given. Draw a line through these points. The slope of this line is 10.56, which verifies our equation. This:

Using  the scientific definition of work, a greater amount of force does not always result in a greater amount of work because work done is the result of the force applied and the displacement of that object.

The work done on an object when the object shows the displacement with respect to the force applied to it and If the force is applied in the same direction as the displacement, work is done on the object, and the work done is equal to the force multiplied by the displacement. The greater force does not show the greater amount of work, as the work done has different factors that it depends upon.

Hence, using the scientific definition of work, a greater amount of force does not always result in a greater amount of work because work done is the result of the force applied and the displacement of that object.

The centripetal force in uniform circular motion remains constant as long as the object's mass and velocity don't change, since centripetal force is calculated as the mass times centripetal acceleration (Fc = mac).

In uniform circular motion, the centripetal force must remain constant to maintain the motion. The second law of motion given by Newton states that net force is mass times acceleration: net F = ma. We have centripetal acceleration (a = ac) for uniform circular motion, and consequently, Fc, the magnitude of centripetal force is Fc = mac. This equation implies that as long as the mass of the object and its velocity (which together determine ac) remain constant, the centripetal force will also remain constant. It is this force that maintains the object in a circular path, acting towards the center of curvature and altering the direction of the object without changing its speed.

It's important to note that centripetal force is not a particular type of force; rather, it could be provided by any force or combination of forces that act towards the center of the object's circular path, like gravitational force, tension, friction, or any other appropriate force that can cause the required centripetal acceleration for uniform circular motion.

The correct answer is

B. it would move in a line tangent to the circular path

In fact, the centripetal force is the only force that keeps the object in a circular trajectory, pulling the object towards the centre of the circle. When this force is removed, there are no other forces acting on the object, therefore for the law of inertia, the object will continue to move at constant velocity, therefore in the same direction (tangent to the circular path) at constant speed.
