Answer: A) kilograms
Explanation:
The amount of matter in a body is defined as mass, which is a physical quantity that expresses the measure of inertia of a body, determined by the acceleration produced when a force acts on it.
The unit of mass in the International System of Units (SI) is the <u><em>kilogram</em></u>, which was defined for many years from a standard object (the international prototype of the kilogram located at the International Office of Weights and Measures). However, since of May 20, 2019, its definition became linked to Planck's constant
Answer:
Radius of the salami = 9.9 cm
Explanation:
The formula for calculating the radius is given below:
a = v^2/r
where a represents acceleration
v represents velocity
r represents radius
As hungry mouse ran around the salami's circumference with a tangential speed of 0.17 m/s so that means velocity = 0.17 m/s.
The centripetal acceleration of the mouse = 0.29 m/s^2
putting these values in the above formula, we get
0.29 = 0.17^2 / r
After rearranging, we get,
r = 0.17^2 / 0.29
r = 0.099 m
r = 9.9 cm
so the radius of the salami = 9.9 cm
