Answer:
9.8 times 5?
Explanation:
this is a freefall question so i think that is what it is.
In order to recreate the process of energy production that takes place in the Sun, scientists use nuclear fusion.
Answer:
4.3 N/m
Explanation:
m = 230 g = 0.230 kg, x = 8.2 cm
in 13 oscillations, time taken = 19 s
In 1 oscillation, time taken = 19 / 13 = 1.46 s
By the use of formula of time period , Let k be the spring constant.
0.054 = 0.230 / k
k = 4.26 N/m
k = 4.3 N/m
A). No. The medium is glass.
B). Yes. There is no material between the satellite and Earth,
only vacuum.
C). No squared. The rings are not electromagnetic waves, and
the material is water.
D). No squared. Sound is not an electromagnetic wave, and
the material is air.
We can use the equation of motion:
s = ut + 1/2 x at²
Both the velocity and acceleration are downwards so we'll consider the downward direction positive
30 = 8t + 4.91t²
4.91t² + 8t - 30 = 0
Solving the quadratic:
t = 1.79 s; t = -3.42 s
Negative time is not possible so second value discarded. Time taken = 1.79 seconds
