A 24 V battery is connected to a voltage divider circuit consisting of a 1 resistor and a 2 resistor. What is the voltage across the 2 resistor?

A stationary charge is located between the poles of a horseshoe magnet. The magnetic force exerted by the charge is zero.

Charge is the physical property of matter which cause a particle to attract or repel when placed in its field.

A stationary charged particle does not interact with a static magnetic field. A charge placed in a magnetic field experiences a magnetic force. There will be no magnetic force acting on a stationary charge. The charge must be moving in order to have magnetic force on it.

Thus, the magnetic force exerted by the charge is zero.

Explanation:

drag is the force that acts against any moving object.

if it takes him any amount of time to get from one speed to another, it is caused by drag.

The statement which are Aristotle’s beliefs about motion EXCEPT option a.

Aristotle's theory of motion believed that all motion was centered upon the object trying to reach its natural resting position.

The theory states that it requires a force to make an object move in an unnatural" manner.

Until and unless a force is applied, the motion is continued or remains stopped.

Thus, all the statements are correct except Objects move according to natural tendencies.

trigonometry (guessing)

Explanation:

ellipse: is the shape of an orbit : looks like an oval

periapsis : shortest distance between something like the moon and the planet its orbiting around like the earth

parallax is triangulation. like how gps works. looking at a star one day and then looking at it again 6 months later, an astronomer can see a difference in the viewing angle for the star. With trigonometry, the different angles yield a distance. This technique works for stars within about 400 light years of earth

https://science.howstuffworks.com/question224.htm

By comparing the intrinsic brightness to the star's apparent brightness we can calculate the distance of stars

1/r^2 rule states that the apparent brightness of a light source is proportional to the square of its distance.Jan 11, 2022

https://www.space.com/30417-parallax.html

alternative distance measurement for stars used by most astronomers is the parsec. A star with a parallax angle of 1 arcsecond has a distance of 1 parsec, or 1 parsec per arcsecond of parallax, which is about 3.26 light years

The half-life of a substance is the time the substance takes to decay until the amount of the sample is half of its initial amount.

In this problem, the half-life of iodine-131 is 8 days. This means that after 8 days, only half of the initial sample will be left. After another 8 days (16 days), the sample will be reduced by another factor 1/2, so only 1/4 of the initial sample will be left.

Since the initial sample was 0.96 g, after 16 days the amount of iodine left is m = 1(0.96g) = 0.24g

Answer:

24 days

Explanation:

This is because the half-life is eight days. If you add another half-life, which will be 16 days, 1/4 of the sample remains, and if you add another half-life which is 24 days, 1/8 will remain.

If the resistance decreases to (1/4) of its original value while the voltage remained constant, the resulting current is 8A.

Option D) is the correct answer.

Ohm’s law states that "the potential difference between two points is directly proportional to the current flowing through the resistance.

It is expressed as;

V = I × R

Where V is the voltage or potential difference, potential difference, I is the current and R is the resistance.

Given that the circuit has a current of 2A, this means;

V = 2A × R

Next, the resistance in the circuit decreases to one-fourth of its original amount while the voltage remains constant

V = I' × (1/4)R

So we can equate.

2A × R = I' × (1/4)R

2A × R = I' × R/4

2AR = I'R/4

8AR = I'R

I' = 8AR / R

I' = 8A

If the resistance decreases to (1/4) of its original value while the voltage remained constant, the resulting current is 8A.

Option D) is the correct answer.

It is possible to predict the speed that a coaster will reach before it is ever placed on the track  by using the conservation of energy principle.

The principle of energy conservation states that energy can neither be created nor destroyed. It may transform from one form to another form.

Just like in roller coaster, velocity at the maximum height is predicted by using this principle. At the maximum height, potential energy is maximum and kinetic energy is minimum.

Thus, It is possible to predict the speed that a coaster will reach before it is ever placed on the track  by using the conservation of energy principle.

Answer:

No, projectile launched at 20° landed first.

Explanation:

70° projectile had a vertical velocity of v*sin(70), which is significantly bigger than v*sin(20). Since v=vx+at, we can see that [tex]Vyi*sin(20)-gt < Vyi*sin(70)-gt[/tex]

solve for t, you can check that by substituting velocity for any number.

Answer:

well,they may or they may not. It all depends on the vertical components of the speed with which the projectile is thrown.

Explanation:

to derive the time of flight :

Considering the vertical motion (along y axis) , the journey from the ground to highest point

v=u+at ,where v=final velocity , u=initial velocity , acceleration due to gravity i.e g and t is the time taken by the particle to reach the highest point

o=u(sin theta) + (- g)t

t=u(sin theta) - g

Hence total time of flight is twice of that i.e

T=2(vertical components of speed) / g

So, if two projectile have some vertical components of velocity , they will have equal time of flight.

The final temp of the gold cube will be 30.773 °C. The heat absorption principle is used in the given problem.

The amount of heat required to increase a substance's temperature by one degree Celsius is known as specific heat capacity.

Similarly, heat capacity is the relationship between the amount of energy delivered to a substance and the increase in temperature that results.

Mathematically, specific heat capacity is given by;

\rm Q= Ms \triangle t

Where,

Q is the amount of energy necessary to raise the temperature

M is the mass

Δt is the time it takes to raise the temperature.

s stands for specific heat capacity

While t stands for temperature change.

The given data in the problem is;

The energy required to raise the temperature is 430 joules.

M is the mass of gold = 250 g

s is the specific heat capacity of silver= (0.3 J/°Cg),

ΔT is the temperature fluctuation

The specific heat capacity is given by;

[tex]\rm Q= Ms \triangle t \\\\ \rm 430= 250 \times 0.3 \times (T_f-25)\\\\ T_f=30.773 ^0 C[/tex]
