A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 5.12 g coins stacked over the 24.2 cm mark, th

pashok25 [27]

Answer:

The mass of the meter stick is $1.66054054054g$

Explanation:

Here since the meter stick is in equilibrium position its net torque and net force should be equal to zero

Since at the begging the meter stick is balanced at center of the meter stick that means its center of mass should be present at $50.0cm$

Now lets consider the later case where stick is balanced by two 5.12 g coins .

Here torque due to two coins = $t_{c} = 5.12\times(27.8-24.2)\times2\times9.8$

Torque due to weight of meter stick = $t_{m}$ = $m\times(50-27.8)\times9.8$

where m = mass of the meter stick

Here $t_{c} = t_{m}$ .

Upon equating we will be getting mass of the meter stick = $1.66054054054g$

The equivalent resistance of two resistors connected in series is always greater than the equivalent resistance of the same two

seraphim [82]

Answer:

True

Explanation:

Because the resistors in series is the sum of the two resistors given as

R= R1+R2

While that of resistors in parallel is the sum of the reciprocal of the resistance given as

1/R = 1/ R1+ 1/R2

So that of series connection will be greater

a bus starts from rest and attains 40 kilometres per hour velocity after 10 seconds calculate the acceleration of the bus in km

igomit [66]

Answer:

Acceleration = Final velocity-initial velocity/time

In m/s^2

a = 40000-0 /10

= 4000m/s

in km/h

a = 40/10÷360

= 1440km/h
