An ocean wave is an example of a(n) _____ wave form.transverse
longitudinal
compression
circular

Answers

An ocean wave is an example of a circular wave form. Circular waves are also called orbital waves. These type of waves combines the other two types of waves namely the longitudinal and transverse wave forms. Orbital or circular waves happens at the interface between two substances having different densities.

An ocean wave is an example of a(n) transverse wave form. Therefore option 1 is correct.

Transverse waves are characterized by the displacement of particles perpendicular to the direction of wave propagation. In other words, the oscillations of the particles occur in a direction that is perpendicular (or transverse) to the direction of wave travel.

When an ocean wave forms, the particles of water move up and down in a vertical motion, while the wave itself moves horizontally. This up-and-down motion of the water particles is perpendicular to the direction in which the wave is traveling, making it a transverse wave.

Which of the following is a type of antimatter created in some nuclear fusion reactions within stars?A. photon
B. positron
C. neutrino
D. helium-4

Answers

A type of antimatter created in some nuclear fusion reactions within stars is B. Positron. Antimatter is composed of antiparticles, and is considered to be the opposite of matter. Its antiparticles have the same mass as ordinary particles, but they have the opposite charge. When matter and antimatter come into contact, annihilation or destruction occurs.

Answer:

The answer is B i just took the test and got it correct:)

Explanation:

The total energy of a 0.050 kg object travelling at 0.70 c is:A) 2.10 × 107 J

B) 3.06 × 107 J

C) 2.46 × 1015 J

D) 6.30 × 1015 J

E) 8.82 × 1015 J

Answers

Answer:

1.1025×10^15Joules

No correct option

Explanation:

The type of energy possessed by the object is kinetic energy. Kinetic energy is the energy due to virtue of an object motion.

KE = 1/2MV² where;

M is the mass of the car = 0.05kg

V is the velocity of the car

Since the car is traveling at 0.7c (c is the speed of light)

speed = 0.7c { 0.7(3×10^8)}

Speed = 2.1×10^8

Substituting this values in the formula given we have;

KE = 1/2×0.05×(2.1×10^8)²

KE = 1.1025×10^15Joules

No correct option.

During a thunder storm, movement of water molecules within clouds creates friction which causes the bottom of the clouds to become negatively charged. This means that the bottom of the cloud and the ground begin to act like parallel plates. Once the electric field between the clouds and the ground becomes larger than 3.0 x 10^6 N/C, lightning will strike. a. If the bottom of the cloud is 150 m above the ground, determine the electric potential difference between the ground and the cloud.

Answers

the distance between the charges, or so called infinite charge plates is 150 m, the magnitude of the electric field is 3 x 10^6 N/C and we need to find the voltage, or potential energy, the electric field magnitude is defined as:

E = V/d

therefore, the potential is:

V = E * d

so we have:

V = 3 x 10^6 * 150 = 450 x 10^6 J/C (or volts)

that is the electrical potential difference.
