Which part of the electromagnetic spectrum is nearest to radio waves?
X-rays
microwaves
gamma rays
ultraviolet light
Answer:
i believe it is the microwaves that is closest to the radio waves.
Explanation:
The microwaves are the part of the electromagnetic spectrum is nearest to radio waves.
What is meant by electromagnetic spectrum?The range of all EM radiation arranged from high to low frequency (short to long wavelength) according to their frequency or wavelength. is known as the electromagnetic spectrum (EM).
Here,
The visible light from a bulb in your home and the radio waves from a radio station are two examples of electromagnetic radiation. Radiation is energy that travels and disperses as it does.
The properties of the electromagnetic spectrum include the ways in which signals can propagate and how much data they can carry. Signals delivered at higher frequencies typically propagate more quickly but can carry more data in a given amount of space.
The electromagnetic spectrum begins with the lowest frequency radio waves and moves up in frequency and down in wavelength from there. Radio waves are followed by visible light, infrared radiation, and lastly microwaves.
Hence,
The microwaves are the part of the electromagnetic spectrum is nearest to radio waves.

A layer of water Δx m thick which lies x m above the bottom of the tank will be rectangular with length 8 m. Using similar triangles, we can see that it will have widt of_____m
Answer:
x
Explanation:
The question relates to the energy required to pump water out of the
spout at the top of the triangular prism tank.
The width of the layer of water Δx thick is x m.
Reasons:
The location of the layer Δx m thick = x meters above the bottom
The length of the triangular (cross-section) prism tank = 8 meters
The length of the layer Δx thick layer = 8 meters
From the attached drawing of the cross-section of the tank, we have;
The height of the triangular tank cross-section = 3 meters
The length of the base of the triangular cross-section = 3 meters
By similar triangles, we have;
[tex]\dfrac{Height \ of \ Tank}{Base \ length \ of \ tank}= \dfrac{Height \ of \ layer \ with \ thickness \ \Delta x }{Width \ of \ layer \ with \ thickness \ \Delta x}[/tex]
Which gives;
[tex]\dfrac{3}{3} =\dfrac{x}{Required \ width}[/tex]
[tex]\dfrac{3}{3} =1 = \dfrac{x}{Required \ width}[/tex]
Required width × 1 = x
The required width = x m

How could you explain that two objects of the same volume have different buoyancy in water???
HELP ITS URGENT
Answer:
Explanation:
Take for example you place two eggs in the water. One starts to sink and one remains floating. They have the same volume but the one that sinks is cracked just a little, which as soon as it hits the water, water starts to go in the egg. Then that changes the volume of the egg. (I've done this expirement before) It can also be the way you place the object in the water, or one object has been in the water longer. The buoyancy can be the way they are positioned/placed in the water. One may be more absorbant to the water as well.

Calculate the resistance of an electric blanket that draws 9 A to transform 50 W of energy.
Answer:
The resistance is 0.617Ω.
Explanation:
Given that the formulas are V = I × R and P = I × V so when you substitute the V formula into P formula, you will get P = I² × R. Using this formula, you can find the resistance :
P = I² × R
50 = 9² × R
50 = 81 R
50 ÷ 81 = R
R = 0.617Ω (3sf)

Which part of this chemical process requires energy? KOH + HBr - KBr + H20 A. Forming bonds in KOH and HBr B. Breaking bonds in KBr and H2O C. Breaking bonds in KOH and HBr D. Forming bonds in KBr and H2O
The chemical process which requires energy is breaking bond in KOH and HBr. Hence, option C is correct.
What is energy?The capacity to perform work is known as energy in physics. Potential, kinematic, thermodynamic, electromagnetic, chemical, nuclear, and other types are all possible.
As energy is transferred through one body to another, there is also heat and work. As a result, heat transfer may result in thermal energy, whereas labor done may result in mechanical power.
As per the given reaction in the question,
KOH + HBr - KBr + H20
Here, in this reaction the chemical process which requires the energy is at the time of breaking of bonds in KOH and HBr at that time the energy is required.
Therefore, it is concluded that breaking bonds in KOH and HBr i.e., option C is correct.

A force of 6.0 N is applied horizontally to a 3.0 kg crate initially at rest on a horizontal frictionless surface. After the crate is pushed for 1.5 seconds, it has a velocity of 3.0 m/s. Does this support Newton's second law of motion, that force equals mass times acceleration? Explain. 
a. Yes, because the acceleration of the crate is 2.0 m/s².
b. No, because the acceleration of the crate is 2.0 m/s².
c. Yes, because the mass and the velocity of the crate are equal.
d. No, because the mass and the velocity of the crate are equal.
Answer:
a. Yes, because the acceleration of the crate is 2.0 m/s².
Explanation:
Given
[tex]Force = 6N[/tex] --- f
[tex]Mass = 3kg[/tex] --- m
[tex]Time = 1.5s[/tex] --- t
[tex]Velocity = 3.0m/s[/tex] --- v
Required
Does the system support [tex]F=ma[/tex]
Yes, it does and this is shown below
The crate is initially at rest; so:
[tex]u = 0[/tex]
Using the first equation of motion
[tex]v = u + at[/tex]
Substitute values for v, u and t
[tex]3 = 0 + a*1.5[/tex]
[tex]3 = 1.5a[/tex]
Make a the subject
[tex]a = 3/1.5[/tex]
[tex]a = 2[/tex]
Using [tex]F = ma[/tex]
Substitute values for F and m
[tex]6 = 3 * a[/tex]
Divide both sides by 3
[tex]6/3 = 3/3 * a[/tex]
[tex]2 = a[/tex]
[tex]a = 2[/tex]
In both cases:
[tex]a = 2[/tex]
Hence, option (a) is correct.
