A. All natural radiation is at a level low enough to be safe
Answer:
a system of physical units ( SI units ) based on the metre, kilogram, second, ampere, kelvin, candela, and mole, together with a set of prefixes to indicate multiplication or division by a power of ten.
Explanation:
The problem here was not the error; it was the failure of NASA's systems engineering, and the checks and balances in our processes, to detect the error. That's why we lost the spacecraft.
As the banana flies through space, up the red arrow showing its path of motion takes a curved or parabolic shape.
<h3>What is a projectile?</h3>
A projectile is an object launched into space at an angle to the horizontal ground and allowed to fall freely under gravity.
The path of motion of a projectile is parabolic.
Examples of objects that are projectiles include:
- A thrown banana
- A kicked football
- An arrow shot from a bow
Therefore, as the banana flies through space, up the red arrow showing its path of motion takes a curved or parabolic shape.

Answer:
the apparent weight of the astronaut in the rocket is 3723 N.
Given:
acceleration = 34 
mass of astronaut = 85 kg
To find:
Apparent weight of the astronaut = ?
Solution:
Total weight of the astronaut in a rocket is given by,
W = w + F
W = apparent weight of the astronaut
w = weight of astronaut on earth surface = mg
F = force acting on the astronaut = ma
W = mg+ma
W = m (g+a)
W = 85 (9.8 + 34)
W = 3723 N
Thus, the apparent weight of the astronaut in the rocket is 3723 N.
