The information that could be gathered about a star whose light curve has multiple symmetrical depths is ; The shape and surface variegation of the star
The light curves of a KBO ( moons and stars ) are measured as a rate of the brightness of a star in relation to time. therefore the study of the light curve having multiple symmetrical depths ( depth of brightness ) will give an information about the shape/size and the surface variegation of the star
Hence we can conclude that The information that could be gathered about a star whose light curve has multiple symmetrical depths is ; The shape and surface variegation of the star

Answer:
Explanation:subtract all of those by the all of the other numbers and that’s the answer i think that’s the way I learned it
Answer:
Explanation:
r = Radius = 2.7 cm
F = Force =
A = Area =
= Stress =
E = Young's modulus =
= Strain
= Original length = 67 cm
= Change in length
Young's modulus is given by
Strain is
Strain is given by
The cylinder height decreases by
Given gravitational potential energy when he's lifted is 2058 J.
Kinetic energy is transferred to the person.
Amount of kinetic energy the person has is -2058 J
velocity of person = 7.67 m/s².
<h3>
Explanation:</h3>
Given:
Weight of person = 70 kg
Lifted height = 3 m
1. Gravitational potential energy of a lifted person is equal to the work done.
Gravitational potential energy is equal to 2058 Joules.
2. The Gravitational potential energy is converted into kinetic energy. Kinetic energy is being transferred to the person.
3. Kinetic energy gained = Potential energy lost =
Kinetic energy gained by the person = (-2058 kg.m/s²)
4. Velocity = ?
Kinetic energy magnitude=
Solving for v, we get
The person will be going at a speed of 7.67 m/s².
