When a force of 30 N acts on a certain object the acceleration of the object is 5 m/s^2 if the acceleration becomes is 8m/s ^2 w

Varvara68 [4.7K]

Answer:

48 N

Step-by-step explanation:

The equation for force is

F = m * a

where F is force, m is mass, and a is acceleration

30N = m * 5m/s²

m = 6 kg

F = 6kg * 8m/s² = 48 N

Sid starts with savings of £13

vfiekz [6]

Answer:

after 6 weeks

Step-by-step explanation:

Sid and Tim starts saving each week.

Sid starts his savings with initial amount of £13.00

Tim starts his saving with initial amount of £00.00

Each week from now Sid will save = £3.50

Tim will save each week = £3.00

Let's assume after 'x' weeks the amount of Sid would be = £ (13 + 3.50x)

and the amount of Tim's saving after x weeks = £ (3x)

The ratio of their savings in x weeks would be = 17 : 9

Now the expression we get,

(13 + 3.50x) : (3x) = 17 : 9

$\frac{13+3.50x}{3x}=\frac{17}{9}$

9(13 + 3.50x) = 17(3x)

117 + 31.5x = 51x

117 = 51x - 31.5x

117 = 19.5x

$x=\frac{117}{19.5}$

x = 6

After 6 weeks the savings of Tim and Sid would be in the ratio of 17 : 9.

$\\ \rm\Rrightarrow 2y=x-4$

$\\ \rm\Rrightarrow y=x/2-2$

m=1/2

Parallel lines have equal slope

Equation in point slope form

$\\ \rm\Rrightarrow y-4=1/2(x-1)$

$\\ \rm\Rrightarrow 2y-8=x-1$

$\\ \rm\Rrightarrow x-2y+7=0$

#2

$\\ \rm\Rrightarrow 1/2y-3x=2$

$\\ \rm\Rrightarrow 1/2y=3x+2$

$\\ \rm\Rrightarrow y=6x+4$

m=6

Parallel lines have equal slope

Equation of line

$\\ \rm\Rrightarrow y-6=6(x+2)$

$\\ \rm\Rrightarrow y-6=6x+12$

$\\ \rm\Rrightarrow 6x-y+18=0$

#3

$\\ \rm\Rrightarrow 1/k x+5=3y\implies y=x/3k+5/3$

m1=1/3k

$\\ \rm\Rrightarrow y=(2/k+3)x-6/(k+3)$

m2=2/k+3

Slopes remain same

$\\ \rm\Rrightarrow \dfrac{1}{3k}=\dfrac{2}{k+3}$

$\\ \rm\Rrightarrow k+3=6k$

$\\ \rm\Rrightarrow 5k=3$

$\\ \rm\Rrightarrow k=3/5$
