what's the difference between work and power

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.

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.

Explanation:

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.

Explanation:

when there is an increase in thermal energy, the kinetic energy if the matter increases as well.

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.

Answer:

0.0001158443168226212 Celcius (significant digits? who cares.....) or about 0.00021 Fahrenheit

Explanation:

500g=0.5kg

PE=mgh

PE=(0.5)*(9.81)*(1.5)

PE=7.36J

3% of 7.36 is 0.22J is converted to heat

From there, it's tricky.

I just used a joules to celcius converter to get 0.0001158443168226212 degrees celcius or 0.00021 degrees fahrenheit rise in temp.

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:

[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:

--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:

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.

I HOPE THIS ANSWER WILL HELP YOU!!!

Answer:

1. The elastic potential energy is 0.0176 Joules

2. The kinetic energy of the pinball the instant it leaves the spring is 0.0176 Joules

3. The speed of the pinball the instant it leaves the spring is approximately 2.42212 m/s

4. The height of the part where the pinball is located on the machine above the ground is approximately 0.213 meters

Explanation:

The spring constant of the pinball machine's plunger, k = 22 N/m

The amount by which the pinball machine's plunger is compressed, x = 0.04 m

The mass of the pinball ball, m = 0.006 kg

1. The elastic potential energy, P.E. = 1/2·k·x²

By substitution, we get;

P.E. = 1/2 × 22 N/m × (0.04 m)² = 0.0176 J

The elastic potential energy, P.E. = 0.0176 J

2. At the instant the pinball leaves the spring, the plunger and therefore the force of the plunger no longer acts on the pinball

Since there are no external forces acting on the pinball to increase the speed of the pinball after it leaves the spring, the velocity reached is its maximum velocity, and therefore, the kinetic energy, K.E. is the maximum kinetic energy which by the conservation of energy, is equal to the initial potential energy

Therefore;

K.E. = P.E. = 0.0176 J

The kinetic energy of the pinball the instant it leaves the spring, K.E.= 0.0176 J

3. The kinetic energy, K.E., is given by the following formula;

K.E. = 1/2·m·v²

Where;

v = The speed or velocity of the object having kinetic energy K.E.

Therefore, from K.E. = 0.0176 J, and by plugging in the values of the variables, we have;

K.E. = 0.0176 J = 1/2 × 0.006 kg × v²

v² = 0.0176 J/(1/2 × 0.006 kg) = 88/15 m²/s²

v = √(88/15 m²/s²) ≈ (2·√330)/15 m/s ≈ 2.42212 m/s

The speed of the pinball the instant it leaves the spring, v ≈ 2.42212 m/s

4. The height of the pinball is given by the following kinematic equation of motion;

[tex]v_h[/tex]² = u² - 2·g·h

Where;

[tex]v_h[/tex] = The velocity of the pinball at the given height = 1.3 m/s

u = v ≈ 2.42212 m/s (The initial velocity of the pinball as it the spring)

g = The acceleration due to gravity ≈ 9.8 m/s²

h = The height of the pinball above the ground

We get;

[tex]v_h[/tex]² = 1.3² = 2.42212² - 2 × 9.8 × h

∴  h = (2.42212² - 1.3²)/(2 × 9.8) ≈ 0.213

The height of the part where the pinball is located on the machine above the ground, h ≈ 0.213 m

Answer:

I would say both

Explanation:

Each silicon atom has four valence electrons which are shared, forming covalent bonds with the four surrounding Si atoms.

Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules. The simplest organic carbon molecule is methane (CH4), in which four hydrogen atoms bind to a carbon atom (Figure 1).

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
