1. An object is accelerated at a rate of 5 m/s²? Find the mass of the object if the force exerted on it is 4 x 10⁵dynes. (Note:
torisob [31]

Step-by-step explanation:

\begin{gathered}\frak \red{Given}\:\begin{cases} \:\quad\sf  Acceleration \:of \ \: a\:body\:,\:a\:=\:\pmb{\frak{5\:m/s^2\:}}\:\\ \:\quad\sf Force \:Exerted\:on\:a\:body\:,\:F\:=\:\pmb{\frak{\:4\times 10^5\: dynes\:}}\:\end{cases}\\\\\end{gathered}

<h2><u>Need To Find : </u></h2>

  • The mass of a body ?

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━⠀

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━⠀

We're Provided with the , Acceleration (a) , and Force Exerted (F) on a body and , we'll find Mass (m) of the object using the <u>relation</u>

 between <u>Force , Mass & Acceleration </u> and, that is : 

\underline {\pmb{\sf \: F\:=\:m\:\times \:a \:}}

\\ \twoheadrightarrow \sf F \:=\:m\:\times \:a

: \rightarrow \sf 4 \:\times 10^5 \:=\:m\:\times \:5\:

\\  \\  \\ \\\twoheadrightarrow \sf 4 \:=\:m\:\times \:5\:\:\Bigg\lgroup \:1 \:N\:=\:1\:\times 10^5\:dynes\:\Bigg\rgroup\\

\\ \twoheadrightarrow \sf 4 \: \:=\:m\:\times \:5\:\\\\\\

\twoheadrightarrow \sf 5m\:=\:4\:\\

\twoheadrightarrow \sf m \cancel{\dfrac{4}{5}}\\\\

\ \twoheadrightarrow \pmb {\underline {\boxed {\purple {\:\frak{ \:m\:\:=\:0.8\:kg\:}}}}}\:\bigstar \: \\

\begin{gathered}\therefore \:\underline {\sf \: Hence,\:Mass\:of\:a\:body\:is\:\pmb{\sf 0.8\:kg\:}\:.}\:\\\\\end{gathered}

EXPLAIN ANSWER PLZ!
Dmitriy789 [7]

height,h = 3"

base, b = length, l = 2

area of triangle, t = bxh/2...eqn 1

area of square, s = l^2...eqn 2

area of pyramid, p =4t + s...eqn 3

subst h = 3 and b = 2 in eqn 1

t = 3x2/2 = 3

subst l =2 in eqn 2

s = 2^2 = 4

subst t = 3 & s = 4 in eqn 3

p = 4(3) + 4 = 16sq inch

Equation of the line that passes through (7,-1) and (-3,-1)
Archy [21]

Answer:

y = - 1

Step-by-step explanation:

Note the y- coordinates of both points are equal, both - 1

This indicates the line is horizontal and parallel to the x- axis with equation

y = c

where c is the value of the y- coordinates the line passes through

The line passes through (7, - 1 ) and (- 3, - 1 ) with y- coordinates - 1 , then

y = - 1 ← equation of line
