You have to go to settings and there will be options im guessing!
Answer:
Discrete
Explanation:
There can be many kind of visible spectrum. Some of them are as follows :Infrared, Continuous
, Blackbody and Discrete.
A neon lamp produces discrete kind of visible spectrum. In this type of spectrum, the spectrum consists of different colors. It means that the neon lamp is made up of different colors or individual frequencies.
Hence, a neon lamp produces discrete visible spectrum.
Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another inside a gravitational field, the force of gravity will do positive work on the object and the gravitational potential.

Answer:
<em>the minimum speed that the ball must have so that the cord does not become slack is</em> <em>2.02 m/s.</em>
<em></em>
Explanation:
In order to avoid slack, the centripetal force of the ball must equal its weight at the top of the circle. Therefore,
F_c = F_g
m v² / r = m g
v² = g r
v = √[g r]
v = √[(9.8 m/s²)(0.417 m)]
<em>v = 2.02 m/s </em>
Therefore,<em> the minimum speed that the ball must have so that the cord does not become slack is</em> <em>2.02 m/s.</em>
Explanation:
It is given that,
Initial speed of the broad jump, u = 12 m/s
It is launched at an angle of 20 degrees above the horizontal. Let t is the time for which the track star i in the air before returning to Earth. The motion of the track star in the broad jump can be treat as the projectile motion. The time of flight of the projectile is given by :
Putting all the values in above equation as :
t = 0.837 seconds
So, the time for which the track star is in air is 0.837 seconds. Hence, this is the required solution.
