Answer:

90 ohms

Explanation:

1/r = 1/180 + 1/180

1/r= 2/180

take the reciprocal of 2/180 which is 180/2 and its 90 ohms

The force of attraction between a -165.0 uC and +115.0 C charge is 6.00 N. What is the separation between these two charges in m

Molodets [167]

Answer:

r = 5.335 meters

Explanation:

Given that,

Charge 1, $q_1=-165\ \mu C$

Charge 2, $q_2=115\ \mu C$

Force of attraction between two charges, F = 6 N

The force of attraction between two charges is given by :

$F=k\dfrac{q_1q_2}{r^2}$ , r is the separation between two charges

$r=\sqrt{\dfrac{kq_1q_2}{F}}$

$r=\sqrt{\dfrac{9\times 10^9\times 165\times 10^{-6}\times 115\times 10^{-6}}{6}}$

r = 5.335 m

So, the separation between two charges is 5.335 meters. Hence, this is the required solution.

Calculate specific heat of liquid if a 450. g iron block is heated to 98.0 C and then droped into a calorimeter with 125 g of un

Naya [18.7K]

Answer:

Specific heat of liquid $1.258 \ J/g^0C.$

Explanation:

We know in thermal equilibrium :

Loss in heat by iron block = Gain in heat by liquid .

Specific heat of iron = 0.45 $J/g^0C.$ { source internet }

Now , loss in heat by iron block = $mC_{iron}\Delta T=450\times 0.45\times 57.6=11664\ J.$

Heat gain by liquid= $mC_{liquid}\Delta T=450\times C_{liquid}\times 20.6=9270\times C_{liquid}.$

Equating both we get :

$C_{liquid}=1.258 \ J/g^0C.$

Two objects are held close together. When they are released, they move toward one another. Which conclusion is supported by this

Liula [17]

Answer:

The objects have opposite charges.

Explanation:

The object when released are moving towards each other simply because they attract each other.

According to coulombs law of charges, like charges repel and will move away from one another.
Unlike charges attracts and moves towards one another
Since the objects are coming towards each other, they are of opposite charges.
