Answer:
The observed wavelength is (color - Red)
Explanation:
From the question we are told that
The wavelength of the emitter is
The redshift is R = 0.4
Generally red shift is mathematically represented as
=>
=>
=>
=>
The rock because it’s ratio is 4:3 and the ratio of the wood is 3:2
For a certain interval of time, an object is acted on by a constant non-zero force. For this interval of time . . . . .
A. The object is at rest. No. From F=ma, if F is not zero, the object can't remain at rest.
<em>B.</em> <em>The object's velocity changes.</em> <em>Yes.</em> From F=ma, if F is not zero, there must be acceleration.
C. The object's velocity can only increase. No. It might decrease.
D. The object is moving with constant velocity. No. From F=ma, if F is not zero, there must be acceleration.
<em>E.</em> <em>The object is accelerating.</em> <em>Yes.</em> From F=ma, if F is not zero, there must be acceleration.
Answer:
angular range is ( 0.681 rad , 0.35 rad )
Explanation:
given data
wavelength λ = 380 nm = 380 × m
wavelength λ = 700 nm = 700 × m
to find out
angular range of the first-order
solution
we will apply here slit experiment equation that is
d sinθ = m λ ...........1
here m is 1 for single slit and d is =
so put here value in equation 1 for 380 nm
we get
d sinθ = m λ
sinθ = 1 × 380 ×
θ = 0.35 rad
and for 700 nm
we get
d sinθ = m λ
sinθ = 1 × 700 ×
θ = 0.681 rad
so angular range is ( 0.681 rad , 0.35 rad )
Answer: a) Believing your talents, abilities, and intelligence can be developed in different ways.
Explanation:
In order to develop a growth mindset, a person must be constantly willing to learn and diversify his/her learning. Learning is not all about going to school and graduating with a degree. Learning has to do with having personal development plan and following it strictly. This is the only way we can develop a growth mindset. We all have talents, we are all intelligent and we all possesses different abilities. One thing is to possess all this things, another thing is putting them into use through constant and unending learning. Through this conscious effort, we can develop a growth mindset instead of a fixed mindset.
