The amount of boiling water required to raise the temperature of 25. 0 kg of water in the bath to body temperature is 4. 80 kg. In this process, the heat lost by the boiling water is equal to the heat gained by the room-temperature water. How much heat was transferred in this process?.

Answer:

4 hours

Explanation:

From hour 2 to 6   the family was not changing distance...they were stationary at the beach for 4 hours

Answer:

whether you can view the eclipse depends on where u live that is why it happens less than every 18 months in your place of residence

Answer:

Accelaration: 2 - 1.875 - 2.167 - 2.25

Explanation:

Acceleration is [tex]\frac{ Ending Velocity-Starting Velocity }{Ending time-Starting time}[/tex]

Acceleration to Time graph and the conclusion would be the description of that slope

Latent heat can not be detected by a thermometer. The mass of water lost is 0.25 g.

The latent heat is the heat that can not be detected by a thermometer but it acts to break the intermolecular bonds in a substance.

Now we know that;

Heat added = 565 * 10^3 J

Heat of vaporization of water = 2,260,000 J/kg

H = mL

m = H/L

m = 565 * 10^3 J/ 2,260,000 J/kg

m = 0.25 g

KE= 1/2 mv^2 = 1/2  1120  40^2 =  

Answer:

The mass=0.169

The height=57.8

The power=1.63 watts

Explanation:

The formula for mass is 2KE/v^2

v=34×34 KE=98 therefore 2*98/34^2=0.169

The formula for height is v^2/2g

v=34*34 therefore 34^2/2*10=57.8

The formula for power is work/time

in which the work is the kinetic energy =98

and time 1*60secs =60 therefore 98/60=1.63watts

How far from a point charge of +2.4x 10-6C must a test charge be placed to measure a field of 360 N/C? E-AV = 400 V = 2X104 N/C d =( 0.020 m 7.)

Explanation:

Answer:

The only way to increase the work output is to increase the work input. You can't get more work out of a machine than you put into it. The moving parts of a machine must use some of the work input to overcome friction. Because of friction, the work output of a machine is always less than the work input.

Answer:

i guess 0.8 miles away

Explanation:

mathematically:-

speed is given in question

Time is given

and we have to find distance

simply by using speed formula (s) = d/t

we get answer

The bolt of  lightning is  0.8 miles far away.

The speed of any moving object is the ratio of the distance covered and the time taken to cover that distance.

Given, is a bolt of lightning and 4 s later we hear the thunderclap. If the speed of sound in air is 0.2 mi/s,

Speed = d/t

D = 0.2 x 4

D = 0.8 miles

Thus, the lightning is  0.8 miles far away.

Answer:

add add more hot water in the flask painted shiny white while less of it in the one painted Matt black

Explanation:

Let's name the flasks A and B respectively

flask A due to the nature of its exterior will tend to reflect heat from the environment thus will need more hot water while flask B since it painted in Matt black the heat will be absorbed from the environment thus will require less hot water

Answer:

There are 6.02*10^23 atoms in each mole (Avagadro no.) That is x moles * avagadro no. According to that, in 23 grams of sodium we have 6.02*10^23 atoms of Na.

Explanation:

The required equation for the sine function can be written as; V = 120sin120πt

A sine function is a regular repeating function. We know that the voltage is represented using a sine function of the general form V= V-o sin2πft

Hence;

f = 60 cycles per second

V-o = 120 volts

So from the values that we have stated above;

V = 120sin120πt

Answer:

Explanation:

Part One

Current = 0.6 amps

Voltage = 12 volts

R = ?

R = E / I

R = 12/0.6

R = 20 ohms

Part 2

Rt = Rspeaker + R

Rt = 20 ohms

R = 4 ohms

Formula

Rt = Rspeaker + R

20 = Rspeaker + 4          Subtract 4 from both sides

Rspeaker = 16 ohms

Part 3

Rspeaker = 16 ohms

I = 0.6 ohms

E = 0.6 * 16

E = 9.6

The strength of the electric field will be 215760 NC⁻¹. The concept of the electric field strength is used in the problem.

The electric field strength is defined as the ratio of electric force and charge. Its unit is NC⁻¹.

The given data in the problem is;

E is the Electric Field Strength

k is the Colomb's constant = 8.99 x 10⁹ N.m²/C²

q is the magnitude of charge = 6 μC = 6 x 10⁻⁶ C

r is the distance = 0.5 m

The electric field strength is given by the formula;

[tex]\rm E = \frac{Kq}{R^2} \\\\ \rm E = \frac{8 .99 \times 10^9 6 \times 10^6 }{(0.5)^2} \\\\ E=215760 \ NC^{-1}[/tex]

Hence the strength of the electric field will be 215760 NC⁻¹.
