Answer:

Four states of matter are observable in everyday life: solid, liquid, gas, and sometimes plasma.

Shape is a characteristic property of matter.

The amount of matter in an object doesn't really affect the characteristic properties of the object

Suppose that a certain battery produces a voltage of 1.55V without a load connected (open circuit) and a current of 500mA when s
lubasha [3.4K]

Answer:

Explanation:

Let the internal resistance be r .

Since in open circuit the volt is 1.55 V , this will be the source voltage .

Source voltage = 1.55

If external resistance be R .

1.55 / (R + r ) = .500

R + r = 3.1 ohm

So sum of internal resistance and external resistance will be 3.1 ohm.

URGENTTT PLEASE HELPPPP. You put m1 = 1 kg of ice cooled to -20°C into mass m2 = 1 kg of water at 2°C. Both are in a thermally i
STatiana [176]

Answer:

Explanation:

heat lost by water will be used to increase the temperature of  ice

heat gained by ice

= mass x specific heat  x rise in temperature

1 x 2090 x t

heat lost by water in cooling to 0° C

= mcΔt  where m is mass of water , s is specific heat of water and Δt is fall in temperature .

= 1 x 2 x 4186  

8372

heat lost = heat gained

1 x 2090 x t  = 8372

t = 4°C

There will be a rise of  4 degree in the temperature of ice.

A 1.5m wire carries a 3 A current when a potential difference of 86 V is applied. What is the resistance of the wire?
Iteru [2.4K]
We know, R = V / I
Here, V = 86 V
I = 3 A

Substitute their values, 
R = 86 / 3
R = 28.67 Ohm

In short, Your Answer would be 28.67 Ohms

Hope this helps!
