HELP ME ASAP PLEASE!!!!!

Physics
1 answer:
solmaris [256]2 years ago
3 0

Answer:

f λ = c = 3.00E8      frequency * wavelength = speed of light

λ = c / f = 3.00E8 / 4.0E14 = 7.5E-7 m

Note 1 angstrom = 1.00E-10 m and 1 milli-micron = 1.00E-9 m

So the wavelength would be 7500 angstroms

The visible spectrum is 4000 A - 7000 A  or 400 - 700 milli-microns

The Earth's gravity keeps us from flying out to space. How can you explain that we have a stronger gravitational attraction to t
julia-pushkina [17]
It's the fourth choice.

This is because, since we are closer to the Earth, the Earth will have a stronger gravitational pull on us since again, we are closer.
That also explains tides, but that's just getting off topic. Hope I helped.

Find the final velocity of a car that accelerates at +2 m/s2 for +4m from an
Stolb23 [73]

Answer:

Explanation:

according to third equation of motion

2as=vf²-vi²

vf²=2as+vi²

vf=√2as+vi²

vf=√2as+vi

vf=√2*2*4+3

vf=√16+3

vf=4+3=7

so final velocity is 7 m/s

A 1000 kg car is moving on flat road at a constant speed of 25 m/s. What is the magnitude of average not force, that is required
Shkiper50 [21]

Answer:-600N

Explanation:

Mass(m)=1000kg

Initial velocity(u)=25m/s

Final velocity(v)=12.5m/s

Time(t)=22 seconds

v=u+axt

12.5=25+ax22

collect like terms

12.5-25=22a

-12.5=22a

Divide both sides by 22

-12.5/22=22a/22

-0.6=a

Acceleration=-0.6

Force=mass x acceleration

Force=1000 x -0.6

Force=-600
