Find the mass of a body if the acceleration the body used to move is given as 5 m/s-2 and the force of the body is 30N take g=10
Aleonysh [2.5K]

The mass of a body if the acceleration the body used to move is given as 5 m/s-2 will be 3 kg.

<h3>What is force?</h3>

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

Force is defined as the product of mass and acceleration. Its unit is Newton.

Given data;

Force,F = 30 N

Mass,m =  kg

Acceleration,a = 5 m/s²

The force is found as;

F=ma

30 N =m kg × 5 m/s²

m=3 kg

Hence the mass of a body will be 3 kg.

To learn more about the force refer to the link;

Why was the geocentric model of the solar system accepted by scientist for many years?
dolphi86 [110]

Answer: Because of the its assumption of earth being at the centre of the universe and also, its parallax argument.

Explanation: Geocentric model is the

theory of the structure of the solar system (or the universe) in which Earth  is assumed to be at the centre of it all. It was generally accepted until the 16th century, after which it was superseded by heliocentric models 

Among many, geocentric model was considered because of its stellar parallax argument.

What is parallax? Parallax is the apparent change in position of objects due to a change in observation location

The ancient Greeks claimed that if the Earth is moving around the Sun then the stars should shift their positions due to this orbital motion (called stellar parallax). The stars don't shift. They don't shift enough for you to notice, but they do indeed shift. This is essentially the same reason the moon appears to follow you around when you drive - it's too far away for any apparent shift due to your motion.

A rabbit trying to escape a fox runs north for 8.0 m, darts northwest for 1.0 m, then drops 1.0 m down a hole into its burrow. W
kifflom [539]

Answer:

9.61 m

Explanation:

d1 = 8 m north

d2 = 1 m north west

d3 = 1 m vertically down

Write the displacements in vector form

\overrightarrow{d_{1}}=8\widehat{j}m

\overrightarrow{d_{2}}=1 \left ( -Cos45\widehat{i}+Sin45\widehat{j} \right )m

\overrightarrow{d_{2}}=\left ( -0.707\widehat{i}+0.707\widehat{j} \right )m

\overrightarrow{d_{3}}=-1\widehat{k}m

The resultant displacement is given by

\overrightarrow{d}=\overrightarrow{d_{1}}+ \overrightarrow{d_{2}} +\overrightarrow{d_{3}}

\overrightarrow{d}=-0.707\widehat{i}+ 8.707\widehat{j} - 4\widehat{k}m

The magnitude of displacement is given by

d =

\sqrt{\left ( -0.707 \right )^{2}+\left ( 8.707 \right )^{2}+\left ( -4 \right )^{2}}

d = 9.61 m
