Answer: VColumn A

Explanation:

In a quadratic relation , variable y is directly proportional to x^2

distance time have the relationship

d = kt²

or

t = kd²

where k is a fixed number (constant).

column A has the perfect squares

: 1, 4, 9, 16...

Therefore d = kt² with k=1:

t = 0, d = 1 x 0² = 0

t = 1, d = 1 x 1² = 1

t = 2, d = 1 x 2² = 4

t = 3, d = 1 x 3² = 9

A disk-shaped grindstone of mass 1.7 kg and radius 8 cm is spinning at 730 rev/min. After the power is shut off, a woman continu

Anastasy [175]

Answer:

0.186 N-m

Explanation:

mass of the grindstone, $m=1.7 kg$

radius, $r=8 cm$

Frequency, $f=730 rev/min = 12.16 rev/s$

time, $t=9s$

final angular velocity, $\omega=0$

Initial angular velocity,

$\omega_o=2\pi f\\=2\pi (12.16) rad/s\\= 76.36 rad/s$

Angular acceleration of the grind stone is:

$\alpha=\frac{\omega-\omega_o}{t}\\\Rightarrow \alpha =\frac{0-76.36}{9} = -8.48 rad/s^2$

Moment of inertia:

$I=mr^2+mr^2=2mr^2$

$I=2\times 1.7 kg\times (0.08m)^2= 0.022kg-m^2$

Torque exerted by the ax on the grind stone is:

$\tau=I\alpha\\\tau=0.022\times (-8.48) \\\tau=0.186N-m$

A point charge has q=1.0×10-6

dmitriy555 [2]

Since the 2 points form a triangle with hypothenuse of √5 [ √(1²+2²)],

I guess apply the formula :

$v = kq \div r$

with r as √5 and q as 1x10^-6

not sure about this answer tho

draw a diagram first to understand better

A body of mass 400 kg is suspended at a lower end of a light vertical chain and is being pulled up vertically. Initially the bod

yKpoI14uk [10]

Answer:31.62 m/s

Explanation:

Given

mass of body $m=400 kg$

Pull on chain is $F_1=6000g N=60 kN$

Pull get smaller at the rate of $F_2=360g N/m$

Net Upward Force $F=6000 g-360 g\times 10=24 kN$

net acceleration $a=\frac{F}{m}$

$a=\frac{24\times 1000}{m}$

$a=\frac{24000}{400}$

$a=60 m/s^2$

but g is acting downward

$a_{net}=a-g=60-10=50 m/s^2$

using $v^2-u^2=2 as$

here initial velocity is zero

$v^2=2\times 50\times 10$

$v=31.62 m/s$
