What is the de Broglie wavelength of a 2.89 x 10-28 kg particle moving
at 3.00 x 108 m/s? (h = 6.626 x 10-34 J-s)
Explanation:
formula is given by
h/mv
where h is 6.626 × 10 ^-34
and c = 3 × 10^8
m = mass
by plugging in the values in the formula, the de Brogile wavelength is equal to 7.6424 × 10^(-15)

Why do we feel the force of gravity from the Earth but we don’t feel the force of gravity from the moon?
Answer:
The gravitational force on the moon is less than on Earth because the strength of gravity is determined by an object's mass. The bigger the object, the bigger the gravitational force. Gravity is pretty much everywhere. We just feel it in different ways depending on our state of motion.

(a) The relative velocity If those trucks move at the same time from the same place is 35 m/s.
(b) The distance between them after 2 minutes is 4,200 m.
Relative velocity of the two trucksThe relative velocity of the two truck is calculated as follows;
Vr = 20 m/s - (-15 m/s)
Vr = 20 m/s + 15 m/s
Vr = 35 m/s

What is the world’s biggest source of electricity production?.
Coal, followed by gas is the largest source of electricity
Coal is the world’s biggest source of electricity production.
The world's biggest source of electricity production is Coal. Coal is a fossil fuel that is mined from the ground and is the largest source of energy for the generation of electricity worldwide. Coal is burned to produce heat, which is then used to boil water and produce steam. The steam drives turbines that generate electricity.
There are other sources of electricity as well, such as natural gas, nuclear energy, hydroelectric power, and renewable energy sources like wind and solar power.
However, coal is the largest source of electricity production in the world.
In a building, air moves due to currents caused by temperature differences. Which
A. statement best describes these currents?

D. They transfer thermal energy due to convection.
Answer:
D. they transfer thermal energy due to convection
In a building, air moves due to currents caused by temperature differences. They transfer thermal energy due to convection. this statement best describes these currents. Hence option D is correct.
What is Temperature ?Temperature is a physical quantity which measures hotness and coldness of a body. Temperature measures the degree of vibration of molecule in a body. Temperature is measured in centigrade (°C), Fahrenheit (°F) and Kelvin (K) in which Kelvin (K) is a SI unit of temperature. Absolute scale of temperature means Kelvin scale of temperature. relation between Kelvin(K) and centigrade (°C), °C= K - 273.15 from equation, 273.15 K means 0 °C, which is freezing point of water (ice). when we give temperature to the body, its molecule or atom absorbs thermal energy and vibrate about their mean position. Amplitude of vibration get increases as we go on increasing temperature and for higher temperature force of attraction between molecules gets weaker. Hence for higher temperature, due to weaken the force of attraction between molecule, solid goes into liquid state. and further increase in temperature liquid goes into gaseous state.
Hence option D is correct.

Two coherent sources of light are three
wavelengths out of phase. does light from these
sources experience constructive interference,
destructive interference, or no interference at all?
explain how you know.
Answer:
The difference phase = 3 λ
In terms of wavelength the difference of phase is zero so the sources would experience "constructive" interphase at that point.
If the light from the sources differed by 1/2, 3/2, 5/2 wavelengths etc, then the sources would be out of phase at that point.
A glass prism can be used to show the dispersion of white light to form a spectrum.
a.Draw a diagram to show how a ray of white light is dispersed as it passes through a prism.
b.Which colour of light is most strongly dispersed (deflected) as it passes through the prism?
c.Explain why some colours of light are more strongly dispersed than others.
For each of the following statements, decide whether it is true or false.
a) For Diagram refer to the attachment.
b) The colour that dispersed most is violet.
c) Every colour has its own wavelengths/ frequency. Different colours move with same speed in air / vaccum. But their speeds in refracting media like glass are different. Therefore, refractive index of the medium for different colours is different. Some gets strongly dispersed due to shorter wavelengths.
Explanation :
Dispersion of Light : The splitting up of a white light into different colours is called Dispersion of light. The light is made up of different colours. Each colour travels at its own speed inside a prism. Due to this different colours of light bend through different angles with respect to the incident ray , as they pass through a prism. The eed light bends the least while the violet the most. Thus, the rays of each colour emerge along different paths and thus becomes distinct.5.

If a 40.1 g piece of iron at 652 °C is dropped into a sample of 328 g of water at 32.4 °C, what will the final temperature be after thermal equilibrium is established? Assume that no heat is lost during the process. specific heat capacity of iron is 0.45 J/g C and water is 4.184 J/g C. SHOW YOUR WORK.
The final temperature of the mixture after thermal equilibrium is reached given the data is 40.4 °C

Spaceship I, which contains students taking a physics exam, approaches Earth with a speed of 0.60c, while spaceship II, which contains instructors proctoring the exam, moves at 0.28c (relative to Earth) directly toward the students. If the instructors in spaceship II stop the exam after 50 min have passed on their clock, how long does the exam last as measured by (a) the students (b) An observer on the Earth?
Answer:
Let β = v / c
proper time Δt' is measured in a frame at the same place in a given frame - the proper time is measured in spaceship II moving at .28 c
a) spaceship I is moving at (.6 - .28) c = .32 c relative to proper time
Δt = Δt' / (1 - β^2)^1/2 as measured by students in ship I
Δt = 50 / (1 - .32^2)^1/2 = 52.8 m measured by students
b) Δt = 50 / (1 - .28^2)^1/2 = 52.1 min time elapsed for observer on earth

When an ice pack is applied to an injury, thermal energy from the injured area transfers to the ice, causing the blood
vessels within the area to constrict, which reduces the swelling.
How is thermal energy transferred in this scenario?
a conduction
b convection

Thermal energy from the injured area transfers to the ice and the thermal energy transferred in this scenario is conduction.
What is Heat transfer by conduction?
Conduction heat transfer is the transfer of heat through matter such as solids, liquids, or gases without bulk motion of the matter.
The ice pack absorbs the heat energy without the actual movement of the molecules of the ice pack.

There are many Autotrophs than consumers because : Autotrophs are the bases of any food chain/web
Function of AutotrophsAutotrophs capture the energy required for every food chain or web from which sustains other organisms in the food chain form sunlight and chemicals. Also there is always more biomass present in the lower levels of the trophic system as biomass decreases as we move up the food chain.
