Can you please tell what "it" is?
Answer:
Nuclear fusion
Explanation:
The reaction shown in the diagram depicts a nuclear fusion.
The reaction expression is given as:
²₁H + ³₁H → ⁴₂He + ¹₀n + energy
This reaction is a nuclear fusion expression. Here two small lighter nuclide to form a product with an attendant emission of a neutron and energy.
The combination of lighter nuclides to form a heavier one is nuclear fusion.
Fusion is different from nuclear fission in which a heavier nuclide splits up.
Answer:
Explanation:
Displacement is minimum distance between initial and final point .
Distance is total length of path covered in a journey .
a )
Tyler covered a longer distance in the journey because total length of path covered by him is longer due to curved path .
b )
Both have same displacement , because minimum distance between initial and final point in both the case is same .
c )
average speed = distance / time
as time is same for both the case ,
average speed ∝ distance
As distance covered by Tyler is more , his average speed is more .
d )
average velocity = displacement / time
As both displacement and time are same in both the case , average velocity in both the case is same .
e )
They start at the same time and place at the bottom of the mountain and finish at the same time , both have tie and nobody won the race , in spite of speed of Tyler being greater .
Answer:
50 is the answer.. the formula is load/effort
Answer:
168 Hz
Explanation:
The Doppler equation describes how sound frequency depends on relative velocities:
fr = fs (c + vr) / (c + vs),
where fr is the frequency heard by the receiver,
fs is the frequency emitted at the source,
c is the speed of sound,
vr is the velocity of the receiver,
and vs is the velocity of the source.
Note: vr is positive if the receiver is moving towards the source, negative if away.
Conversely, vs is positive if the receiver is moving away from the source, and negative if towards.
Given:
fs = 164 Hz
c = 343 m/s
vr = -15 m/s
vs = -23 m/s
fr = fs (c + vr) / (c + vs)
fr = 164 Hz (343 m/s − 15 m/s) / (343 m/s − 23 m/s)
fr = 168 Hz
