Question 1
Ricardo came up with three different designs for paper airplanes. He would like to find out which design flies the farthest. Ricardo plans to fly each paper airplane five times. What step should Ricardo take after he flies each plane?

Answer:

Momentum is the product of mass and velocity. The two types of momentum are angular and linear.

Explanation:

Answer:

Explanation: (Momentum is mass * velocity. Its units, in the SI system are kilogram meter per second) What is Inertia?

In physics, momentum is the product of mass and velocity. The greater the product of this equation, the greater the momentum. In science, there are two types of momentum: angular and linear, which concern different types of moving objects. However, that is not where the definition stops. The word momentum is also used as part of everyday speech, and is one of the very few physics concept whose metaphorical definition is the same as its actual one.

Answer:

Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself.

Answer: They give  you a portion of the thing its fighting so it gets your cells use to it so they can fight it off easily

Explanation:

Answer:

--In the first step, a uranium-235 atom absorbs a neutron, and splits into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy. -- In the second step, one of those neutrons is absorbed by an atom of uranium-238, and does not continue the reaction.

OR

Nuclear fission begins when a neutron hits the nucleus of an atom. The nucleus splits in two and releases thermal energy and releases more neutrons. The neutrons hits the nuclei of more atoms, splitting them and releasing more energy and neutrons.

Answer:

true

Explanation:

Answer: True

Explanation:

Explanation:

Scientists think an Earth without a tilt would be stratified into climate bands that would get progressively colder as you moved away from the equator. Humans would never survive the continuous winter of the high latitudes, and so we would likely congregate in the planet's tropical midsection.

Geothermal energy is not always found in an area that is easily accessible. (C)

Geothermal energy is not a possible energy source for many regions of the country. Because geothermal energy is not always found in an area that is easily accessible. Option C is correct.

Geothermal energy is the thermal energy in the Earth's crust that comes from the planet's creation and the radioactive decay of components in nearly equal amounts.

The disadvantage of using the geothermal energy is;

A. It is available only in limited areas.

B. It can cause air and groundwater pollution.

C. It is difficult to transport from place to place.

Geothermal energy is not a possible energy source for many regions of the country . Because geothermal energy is not always found in an area that is easily accessible.

Hence, option C is correct.

Answer: Pole star can be located using Ursa Major by extending an imaginary line from the last two stars towards the North direction.

Explanation:

Answer:

The pole star can be located using the Ursa Major constellation, by imagining a line towards the Northern direction connecting two stars present at the end of the bowl, This imaginary line meets Pole Star. The length of the imaginary line from the bowl is about five times the distance between the two stars of the bowl.

Answer:

Explanation:

Consider an endless sheet of uniform charge thickness per unit area [tex]\sigma[/tex]  

For a boundless sheet of charge, the electric field will be opposite to the surface. In this way, just the closures of a round and hollow Gaussian surface will add to the electric transition. For this situation, around and hollow Gaussian surface opposite to the charge sheet is utilized. The subsequent field is a large portion of that of a conductor at harmony with this surface charge thickness.  

By balance, we expect the electric field on one or the other side of a plane to be an element of x just to be guided typical to the plane and to point away from/towards the plane contingent upon whether, [tex]\sigma[/tex] is positive/negative.

According to the law;

[tex]2EA = \dfrac{q_{enc}}{\varepsilon_o}[/tex]

[tex]where; \ q_{enc} = total \ enclosed charge = \sigma A \\ \\ thus; \\ \\ 2EA = \dfrac{\sigma A}{\varepsilon_o} \\ \\ E = \dfrac{\sigma}{2 \varepsilon _o}[/tex]

Answer:

Velocity, V = 33.33 m/s

Explanation:

Given the following data;

Mass = 180grams to kilograms = 180/1000 = 0.18 kg

Kinetic energy = 100J

To find the speed;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Substituting into the equation, we have;

100 = ½*0.18*V²

Cross-multiplying, we have;

200 = 0.18*V²

V² = 200/0.18

V² = 1111.11

Taking the square root of both sides, we have;

Velocity, V = 33.33 m/s

Answer:To understand the regional and local climates of Colorado, you must begin with a basic knowledge of Colorado's topography. Colorado lies astride the highest mountains of the Continental Divide. Nearly rectangular, its north and south boundaries are the 41° and 37° N. parallels, and the east and went boundaries are the 102° and 109° W. meridians. It is eighth in size among the 50 states, with an area of over 104,000 square miles. Although known for its mountains, nearly 40 percent of its area is taken up by the eastern high plains.

Of particular importance to the climate are Colorado's interior continental location in the middle latitudes, the high elevation of the entire region, and the mountains and ranges extending north and south approximately through the middle of the State. With an average altitude of about 6,800 feet above sea level, Colorado is the highest contiguous State in the Union. Roughly three-quarters of the Nation's land above 10,000 feet altitude lies within its borders. The State has 59 mountains 14,000 feet or higher, and about 830 mountains between 11,000 and 14,000 feet in elevation.

Answer:C

Explanation:

Answer:

Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.

Answer: Electromagnetic waves are the combination of electric and magnetic field waves produced by moving charges.

The creation of all electromagnetic waves begins with a charged particle. This charged particle creates an electric field (which can exert a force on other nearby charged particles). When it accelerates as part of an oscillatory motion, the charged particle creates ripples, or oscillations, in its electric field, and also produces a magnetic field (as predicted by Maxwell’s equations).

Once in motion, the electric and magnetic fields created by a charged particle are self-perpetuating—time-dependent changes in one field (electric or magnetic) produce the other. Both electric and magnetic fields in an electromagnetic wave will fluctuate in time, one causing the other to change.

Electromagnetic waves (photons) are produced anytime a charged particle experiences a change in velocity.. The electromagnetic wave (radiation) that is produced when the charge particle changes it’s velocity is how energy is conserved. This energy is light.

Explanation:

In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The particles do not move down the tube with the wave; they simply oscillate back and forth about their individual equilibrium positions. Pick a single particle and watch its motion.

[tex]\lambda=5.70\times 10^{-7}\ m[/tex]

Explanation:

The frequency of a sodium vapor lamp, [tex]f=5.26\times 10^{14}\ Hz[/tex]

We need to find the wavelength of light. The relation between wavelength, frequency and speed of light is given by :

[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{5.26\times 10^{14}}\\\\\lambda=5.70\times 10^{-7}\ m[/tex]

So, the wavelength of light is equal to [tex]5.70\times 10^{-7}\ m[/tex].

Answer:

С. 30 m

Explanation:

Given the following data;

Initial velocity, U = 12m/s

Final velocity, V = 18m/s

Acceleration, a = 3m/s²

To find the distance, we would use the third equation of motion;

V ² = U² + 2aS

Substituting into the equation, we have

18² = 12² + 2*3*S

324 = 144 + 6S

6S = 324 - 144

6S = 180

S = 180/6

Distance, S = 30 meters.
