♥ Centripetal force formula ⇒ mv^2/r
♥ Let's solve:
⇒1200/200=v^2/25
⇒1200*25/200=v^2
⇒v^2=150
⇒v=SQRT(150)
⇒=12.2
Keep in mind anything right after the carrot sign is considered a "exponent" or "to the power of."

Answer:
Height as seen by the professor = 38.2 m
Explanation:
Angle of throw = θ = 69°
Velocity of throw = v
X component of velocity = v₁ = v cos 69 = 0.3584 v m/s
Vertical component of the velocity = v₂ = v sin 69 = 0.9336 v m/s
v₂ / v₁ = tan 69 = 2.605
v₂ = 2.605 v₁.
Professor sees as if the x component of velocity =0
v (as seen by professor) + v' = 0
=> v as seen by professor = -v' = -10.5 m/s
This shows that y component of the ball's velocity is 2.605 times its x component of velocity.
with respect to the professor, there is only y component of velocity.
v₂' =v₂ = 2.605 ( -10.5) = 27.4 m/s.
Height as seen by the professor = (27.4)² / 2(9.8) = 38.2 m
Answer:
Newton's Third Law of Motion
Explanation:
Newton's Third Law of Motion which states that, for every action there is an equal but opposite reaction.
This ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects.
In this scenario, a ball bounced by a basketball player on the floor bounces back up at her.
According to Newton's Third Law of Motion, the statement above simply means that in every interaction, there is a pair of forces acting on the two interacting objects i.e the ball and floor. The size of the force on the ball equals the size of the force on the floor. These two forces are called action and reaction forces and are the subject of Newton's third law of motion.
Hence, the ball bounced by the basketball player on the floor would bounce back in equal magnitude.
The magnitude of the acceleration is equal to 31.5
<u>Given the following data:</u>
To determine the magnitude of the acceleration:
In Science, the acceleration of a particle in a <u>circle</u> or circular track is known as centripetal acceleration.
<h3>How to calculate
centripetal acceleration.</h3>
Mathematically, centripetal acceleration is given by this formula:
Substituting the given parameters into the formula, we have;
Centripetal acceleration = 31.5

Answer:
emission of photon is of maximum wavelength when electron transition is from n = 8 to n = 5
Explanation:
Longest wavelength for the transition means the energy difference in two levels must me minimum
So here we know that the energy of electron in a given level is
now if z = 1 for hydrogen
then Energy of electron for n = 2
Energy of electron for n = 5
Energy of electron for n = 8
Now for least energy difference we can say
So emission of photon is of maximum wavelength when electron transition is from n = 8 to n = 5
