The spaceship Intergalactica lands on the surface of the uninhabited Pink Planet, which orbits a rather average star in the distant Garbanzo Galaxy. A scouting party sets out to explore. The party's leader–a physicist, naturally–immediately makes a determination of the acceleration due to gravity on the Pink Planet's surface by means of a simple pendulum of length 1.08m. She sets the pendulum swinging, and her collaborators carefully count 101 complete cycles of oscillation during 2.00×102 s. What is the result? acceleration due to gravity:acceleration due to gravity: m/s2
Answer:
The acceleration due to gravity is
Explanation:
From the question we are told that
The length of the simple pendulum is
The number of cycles is
The time take is
Generally the period of this oscillation is mathematically evaluated as
substituting values
The period of this oscillation is mathematically represented as
making g the subject of the formula we have
Substituting values
He should confront her about it and if after that point she continues report it to the chess team
The total charge on the line of length 1.80 cm is 0.02 x C.
We have an uniform line charge.
We have to determine the charge contained in a section of the line of length 1.80 cm.
<h3>What is the formula to calculate the Electric field due to infinite line charge?</h3>
The formula to calculate the Electric field due to infinite line charge is
According to question -
r = 0.335 m
E = 840 N/C
Therefore -
λ = 2πrE
λ = 2 x 3.14 x 8.85 x x 0.335 x 840 = 15639.7 x N/m =
1.56397 × x = 1.6 x N/m
Now, we know -
λ = Q / L
Therefore, for L = 1.80 cm = 0.018 m -
Q = 0.018 x 1.6 x = 0.02 x C
Hence, the total charge on the line of length 1.80 cm is 0.02 x C.

Answer:
Why sex cells only need half the number of chromosomes compared to other cells in the body? As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.
