365.25 or 366.25 in a leap year

Answer:

The wavelength can always be determined by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.

Explanation:

Thank me later

Answer:

Explanation:

So what you want to do is measure the wavelength for the wavelength by putting the ruler under or above the distance (show in picture).

amplitude you want to measure it inside of the wave. so when measuring move the ruler sideways.

( i hope this makes sense)

Answer:

7.8

Explanation:

Here, an effort of 50 N is applied at the car key and overcomes the resistance(or load) of 390 N at the lid.

mechanical advantage

=load/effort

=390 N/50 N

=7.8

Answer: The main colours of the visible light include:

--> red

--> Green

--> indigo

--> violet

Explanation:

Electromagnetic waves are waves that do not require or need a material medium for its propagation, but they travel successfully in free space (vacuum). These waves exist with an enormous range of frequencies called the electromagnetic spectrum.

Electromagnetic spectrum is defined as the range of all radiation possessing the special characteristics of electromagnetic waves arranged in order of their wavelength or frequency. The electromagnetic spectrum is made up of radio waves, infrared radiation, VISIBLE LIGHT, ultraviolet rays x- rays, gamma rays.

VISIBLE LIGHT: This is a small spectrum from the enormous range of frequencies of electromagnetic radiation. It provides radiant energy and makes things possible to be seen. The wave ranges from 4.5× 10^-7m to 7.0× 10^-7m. When the visible light is passed through a prism, it disperses into different wavelengths according to the colour make up. Dispersion of visible light produces the colors red (R), orange (O), yellow (Y), green (G), blue (B), (I) indigo and violet (V).

Therefore from the options given, red, Green, indigo and violet are examples of visible light spectrum.

Pick any free letter for each trait. For example, "A" for the dominant allele and "a" for the recessive allele for the number of arms. Assuming complete dominance, the genotype for the dominant trait will always have at least one "capital" allele, so a creature with 2 arms would have genotype either AA (homzygous dominant) or Aa (heterozygous), while a creature with the recessive trait of having 4 arms will always be homzygous recessive with genotype aa.

Answer:

a)  m*g*hi = m*g*hf [tex]_{f}[/tex]

         h[tex]_{i}[/tex] = h

b)  ratio = 1.22

c) the potential energy is converted to both rotational kinetic energy and translational kinetic energy

Explanation:

For a frictionless system : initial energy = final energy

i.e. Ei = Ef

a) Prove

Total Initial energy for First cylinder ( Ei ) = m*g*hi      

The final energy of the first cylinder ( Ef ) = m*g*hf

and this energies are purely potential energies

According to conservation of energy :

m*g*hi = m*g*hf

         hi = hf   ( and this holds for both cylinders because they where both kept at the same height initially  )

i.e. initial height = final height ( hence it is proved that both cylinders will reach their initial heights )

b) Determine the ratio of the time taken by both cylinders

lets assume height of incline ( h ) = Lsin[tex]\beta[/tex]

where L = distance covered by cylinder

Final velocity of first cylinder ( V1 )  = [tex]\sqrt{\frac{4}{3} gLsin\beta }[/tex]  

Final velocity of  second cylinder ( V2 ) = [tex]\sqrt{2gLsin\beta }[/tex]

( following the application of the law of conservation of energy )

Given that ; Time taken = displacement / velocity  

hence the ratio = ( h / v1 ) / ( h / v2 )

where h = Lsin[tex]\beta[/tex]

the ratio = 1.22

c) The time for the rolling motion is greater than the time for the sliding motion because the potential energy is converted to both rotational kinetic energy and translational kinetic energy

Answer:

25z

Explanation:

Answer:

Potential energy can transfer into other forms of energy like kinetic energy. Kinetic energy is energy an object has because of its motion.

Explanation:

The ball was released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.

Answer:

The change that has to take place inside the power cord in order for the device to function properly include;

The changing of the alternating current (AC) from the electrical outlet to the direct current having a specific voltage and current value with which the device can be powered

Explanation:

A battery powered device makes use of direct current (DC) electric power from a battery, while the power normally given out at an electrical outlet comes as an alternating current (AC) electric power source.

The power cord for battery-powered device, also known as an AC/DC adapter, that allows them to be plugged into electrical outlets converts the AC electric current it obtains from the electrical outlets to DC electrical current of the appropriate voltage and amperage that the device can make use of for electric power to function and for charging the battery which is the power source for the device

Therefore, the change that has to take place in the power cord is the conversion of the electric outlet alternating current (AC) voltage and amperage values, into direct current (DC) of the required voltage and current for the device

Answer:

Force = 304.5 Newton

Explanation:

Given the following data;

Initial velocity, u = 0m/s (since it started from rest).

Final velocity, v = 42m/s

Time, t = 0.02 secs

Mass = 0.145 kg

To find the force;

First of all, we would have to determine the acceleration of the ball;

Acceleration = (v - u)/t

Acceleration = (42 - 0)/0.02

Acceleration = 42/0.02

Acceleration = 2100 m/s²

Now, we solve for the force;

Force = mass * acceleration

Force = 0.145 * 2100

Force = 304.5 Newton

Answer:

The best-known power of the Supreme Court is judicial review, or the ability of the Court to declare a Legislative or Executive act in violation of the Constitution, is not found within the text of the Constitution itself. The Court established this doctrine in the case of Marbury v. Madison (1803).

Answer:Speed is the time rate at which an object is moving along a path

Velocity is the rate and direction of an object's movement.

Explanation:

Communities cooperate by simply co-existing and working together to benefit the community and offering their goods and services. Some programs in a community offer social work, like volunteering and charities, which help people in need in a community.

They can also be competitive because there are lots of the same goods and services offered throughout the city, so businesses have to compete for sales to attract consumers in the communities.

Explanation:

No, it will not fall. The pencil will remain at zero speed relative to the spacecraft and will orbit the earth with the spacecraft.

Answer:

NASA did not spend millions developing a space pen. The first U.S. astronauts did indeed use pencils and not pens, according to the NASA History Program Office. After a private inventor (Paul Fisher) developed a space pen on his own, he attempted to sell the pens to NASA. At first NASA refused the offer. Pencils lead to unwanted dust in the confined quarters of a space ship,so NASA was searching for an alternative. Unfortunately, ordinary pens do not work in free fall conditions like the astronauts experience. On the surface of the earth, gravity accelerates the ink downward while the pen case is held in place by a person that is held in place by the ground. But in space, both pen and ink are steadily falling so that the ink does not come out. In contrast, Fisher's space pen uses internal pressure to force the ink out,much like an aerosol can. After testing Fisher's pen, NASA became so satisfied with their performance that it started purchasing the pens for $6 a piece. Russian cosmonauts also switched from pencils to Fisher space pens.
