As part of a circus performance, a man is attempting to throw a dart into an apple which is dropped from an overhead platform. U
1 answer:
Answer:
The man has to aim 27.06 cm below the platform.
Explanation:
Given that,
Time = 235 millisecond
Speed = 13 m/s
We need to calculate the distance below the platform
Using equation of motion
Where, u = initial velocity
g = acceleration due to gravity
t = time
Put the value into the formula
Hence, The man has to aim 27.06 cm below the platform.

Answer:
A) x _electron = 0.66 10² m , B) x _Eart = 1.13 10² m , C) d_sphere = 1.37 10⁻² mm
Explanation:
A) Let's use a ball for the nucleus, the electron is at a farther distance the sphere for the electron must be at a distance of
Let's use proportions rule
x_ electron = 0.529 10⁻¹⁰ /1.2 10⁻¹⁵ 1.5
x _electron = 0.66 10⁵ mm = 0.66 10² m
B) the radii of the Earth and the sun are
= 6.37 10⁶ m
tex]R_{Sum}[/tex] = 6.96 10⁸ m
Distance = 1.5 10¹¹ m
x_Earth = 1.5 10¹¹ / 6.96 10⁸ 1.5
x _Eart = 1.13 10² m
C) The radius of a sphere that represents the earth, if the sphere that represents the sun is 1.5 mm, let's use another rule of proportions
d_sphere = 1.5 / 6.96 10⁸ 6.37 10⁶
d_sphere = 1.37 10⁻² mm
