Answer:

Blue..

Explanation:

<em>Energy = plank's constant x frequency </em>

So.. Energy is directly proportional to frequency.... Blue hai higher frequency than orange.

If we measure the temperature of a blackbody to be about 300 K (a typical air temperature in Florida), at what wavelength would

Nostrana [21]

Answer:

9.66 x 10^-6 m

Explanation:

Use the Wein's displacement law

$\lambda _{m}\times T = b$

Where, b is the Wein's constant

b = 2.898 x 10^-3 meter-kelvin

So, λm x 300 = 2.898 x 10^-3

λm = 9.66 x 10^-6 m

a 10. kg ball thrown into the air. it is going 3.0 m/s when thrown. how much potential energy will it have at the top?

Sever21 [200]

Answer:

45 j

Explanation:

At the top, the KE will have been converted to PE

KE = 1/2 mv^2 =PEat-top = 1/2 10 *3^9 = 45 j

What is the rate of change of position in which the same distance is traveled each second ?

abruzzese [7]

Answer:

The rate of change of position in which the same distance is traveled each second is called uniform velocity.

Explanation:

When there is a change in the position coordinate of an object with respect to time, it is has a velocity associated with it.
Similarly, when there is a change in the velocity component of the object with respect to the time, there is an acceleration associated with it.
When the rate of change of position in which the same distance is traveled each second, the object is said to be in uniform velocity. Therefore, there is no acceleration acting on the object.
Since there is no acceleration acting on the object, the net force on the object is zero.

After scientists analyze the results of their experiments, they ____. communicate those results to other people include a contro

Dovator [93]

Answer:

communicate those results to other people

Explanation:

According to my research on the experimental design process, I can say that based on the information provided within the question the next logical step after analyzing the results would be to communicate those results to other people/scientists. That way it advances the scientific field as a whole and provides the results to other scientists that can use those results to implement in other studies.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Two forces are acting on an object. The first force has magnitude F1=33.4 N and is pointing at an angle of θ1=23.8 clockwise fro

lesya [120]

Answer:

a)Fnx = -26.92 N

b)Fny= 8.4 N

c)Fex = 26.92 N

d)Fey = - 8.4 N

e)β = 18.34° clockwise from the positive x axis

Explanation:

Look at the attached graphic

a) What is the x component of the net force acting on the object?

Fnx:x component of the net force acting on the object

Fnx= F₁x+ F₂x

F₁x= 33.4*sin 23.8° = 13.48 N

F₂x= - 46.1*cos 28.8°= - 40.4 N

Fnx = 13.48 N- 40.4 N= -26.92 N

b) What is the y component of the net force acting on the object?

Fny= F₁y+ F₂y

F₁y= 33.4*cos 23.8° =30.6 N

F₂y= - 46.1*sin 28.8°= -22.2 N

Fny=30.6 N-22.2 N = 8.4 N

c) What is the x component of the equilibrant?

Fex: component of the equilibrant

Fex = - Fnx

Fex = - ( -26.92 N)

Fex = 26.92 N

d) What is the y component of the equilibrant?

Fey = - Fnx

Fey = - ( 8.4 N)

Fey = - 8.4 N

e) What is the magnitude of the equilibrant?

$F_{e}$ : equilibrant force

$F_{e} = \sqrt{(F_{e}x)^{2}+{(F_{e}y)^{2} }$

$F_{e} = \sqrt{(26.92)^{2}+{(-8.4)^{2} }$

$F_{e} = 28.2 N$

f) What is the angle the equilibrant makes with the x axis?

$\beta =tan^{-1} (\frac{-8.94}{26.96} )$

β = -18.34° or β = 18.34° clockwise from the positive x axis
