Explanation:

Answer:

B.  85  V

Explanation:

E(rms) = E(peak-to-peak) / squareroot(2)

E(rms) = 120V / 1.414 = 84.9 V

(When  rounded)  =  85  V

The correct option about peak value and effective value of AC sine wave is, “85 V”.

Peak value = 120 V (Given)

Effective value = Peak value ÷ √2

Effective value = 120 ÷ √2

Effective value = 85 V (approximately)

Thus, we can conclude that by dividing the peak value by √2, we will get effective value and multiplying the effective value with √2 will give peak value as result.

Explanation:

PRIMERO ENCUENTRAS LA COMPONENTE x

x = 5.9 m(cos62°) + 7.8 m(cos 29°) = 9.6 m

AHORA LA COMPONENTE y

y = 5.9 m(sen 62°) - 7.8 m(sen 29°) = 1.4 m

PARA ENCONTRAR DESPLAZAMIENTO:

R = [tex]\sqrt{(9.6 m)^{2} + (1.4 m)^{2}}[/tex] = 9.7 m

Answer:

19.1°C

Explanation:

If A and B mix to give 16°C, A has risen by 4°C and B has fallen by 3°C;

If B and C mix to give 23°C, B has risen by 3°C and C has fallen by 5°C;

This means the energy transfered to cause a change of 3°C in B causes a change of 4°C in A and 5°C in C;

We can use this as a ratio (4:5);

The temperature difference between A and C is 16°C;

we add the two parts of the ratio (4+5) to get 9 and divide the temperature difference to get 16/9;

Next we multiply this by one of the parts of the ratio, so with 4, you get 64/9;

This number is the proportional temperature change in A upon mixing;

We then add this to the original temperature of A to get the resultant temperature of the mix like so:

64/9 + 12 = 19.1111...

You can do this alternatively using the other part of the ratio;

We would multiply the 16/9 by the 5 instead of the 4 to get 80/9;

This number is the proportional change in temperature in C upon mixing

Then subtract this from this from the original temperature of C and you should get the same answer:

28 - 80/9 = 19.1111...

Answer: 29.5 degree

Explanation: Given that

Ax = 44.4 m and Ay = 25.1 m 

The direction of the vector will be

Tan Ø = Ay/Ax

Substitute Ay and Ax into the formula

Tan Ø = 25.1/44.4

Tan Ø = 0.5653

Ø = tan^-1(0.5653153)

Ø = 29.48 degree

Ø = 29.5 degree approximately.

Therefore, the direction of the vector is 29.4 degrees approximately.

Answer:

Protons = 28

Neutrons = 42

Explanation:

Alpha decay is one of radioactive decay in which the atomic nuclei can be illustrated by the emission or loss of helium particles of mass number 4 and proton number of 2

Because mass number is the sum of protons and neutrons, If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay, 28 protons will be left in the nucleus and 42 neutrons will be left in the nucleus.

Answer: C

high; large

Explanation:

The wave energy is related to its amplitude and frequency.

The wave energy is proportional to the amplitude of the wave. So, wave with the most energy will have high amplitude.

Also, frequency is related to wave energy. The larger the frequency, the more the energy of the wave.

Therefore, The waves with the MOST energy have high amplitudes and large

frequencies.

The correct statement to describe that when a 100 J of heat energy is added to the system, then the kinetic energy of the system will increase  and the speed of the particles will also increase. Hence, option 3 is correct.

The force that an object has because it is moving is known as kinetic energy in physics. It is defined as the quantity of effort required to accelerate anybody of a specific mass from rest to its specified velocity. The body keeps its kinetic energy after acquiring it during acceleration, barring changes in speed.

When slowing from its current pace to a condition of rest, the body expends the very same amount of energy. Any term in the Lagrangian of a system that has a derivative in regard to time is formally referred to as kinetic energy.

When the energy is added to the system the gap between the particles will increase due to which the velocity of the molecules will increase and with increase in the velocity the kinetic energy will also increase automatically.

C. It decreases as the water releases energy to its surroundings

Explanation:

The energy that is possessed in the body because of the motion is said to be kinetic energy. When the water freezes, the kinetic energy of the water molecules decreases as the particles stop motion. The energy is released in the surrounding. Freezing takes place when the liquid molecules slow down and lose the kinetic energy to form the solid crystals.

The second one is best.  Gravity is an attractive force that acts between all objects, whether they're in contact or not.

Gravity is an attractive force that acts between all objects, whether they're in contact or not.

Gravity, also called gravitation, in mechanics, is the universal force of attraction acting between all matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter.

On the other hand, through its long reach and universal action, it controls the trajectories of bodies in the solar system and elsewhere in the universe and the structures and evolution of stars, galaxies, and the whole cosmos.

On Earth, all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth’s surface, the acceleration of gravity is about 9.8 metres (32 feet) per second per second.

Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second. At the surface of the Moon, the acceleration of a freely falling body is about 1.6 metres per second per second.

Hence Gravity is an attractive force that acts between all objects, whether they're in contact or not.

Answer:a

Explanation:

The throwback PFD is a Type III PFD. This type of PFD is designed for calm, inland water, or where there is a good chance of quick rescue. THe correct option is C.

Type III PFDs will not turn unconscious wearers to a face-up position, so the wearer may have to tilt their head back to avoid turning face down.

Type III PFDs have the same minimum buoyancy as Type II PFD. Float coats, fishing vests, and vests designed for various water sports are examples of Type III PFDs. Some Type III PFDs are designed to be inflated upon entering the water.

Offshore life jackets of Type I are suited for all areas, notably open, choppy, or isolated regions where rescue may be delayed and offer the highest buoyancy. Near-shore vests of Type II PFDs are designed for calm inland water or situations where there is a good probability of prompt rescue. Throwable PFDs of Type IV are suitable for usage in open water as well as calm, heavily used inland waters where assistance is always available. Special-purpose PFDs known as Type Vs are made for activities like kayaking and whitewater rafting.

The throwback PFD is not a Type I PFD because it does not provide the most buoyancy and is not designed for all waters. It is not a Type II PFD because it is not intended for calm, inland water or where there is a good chance of quick rescue.  It is not a Type IV PFD because it is not intended for calm, inland water with heavy boat traffic, where help is always present. It is not a Type V PFD because it is not designed for specific activities such as kayaking or whitewater rafting.

Therefore, the correct option is C. type III.
