Answer:

_20 to 25_ mph

Explanation:

Low beam headlamps are only effective for speeds up to __20 to 25_ mph.At higher speeds Low beam headlamp prove to be ineffective.Low beam headlamps are more effective in Fog, mist or snow. High beam headlamp directly shine in fog or precipitation, reflecting the light back into you.  

hope this helps! ask doubt in the comment section.

The heating element of a coffeemaker operates at 120 V and carries a current of 4.50 A. Assuming the water absorbs all of the en
Bond [772]

Answer:

It will take 313.376 sec to raise temperature to boiling point

Explanation:

We have given that potential difference V = 120 Volt

Current i = 4.50 A

So resistance R=\frac{V}{i}=\frac{120}{4.50}=26.666ohm

Heat flow in resistor will be equal to Q=i^2Rt

It is given that this heat is used for boiling the water

Mass of the water = 0.525 kg = 525 gram

Specific heat of water 4.186 J/gram/°C

Initial temperature is given as 23°C

Boiling temperature of water = 100°C

So change in temperature = 100-23 = 77°C

Heat required to raise the temperature of water Q=mc\Lambda T

So 4.50^2\times 26.666\times t=525\times 4.186\times 77

t = 313.376 sec

So it will take 313.376 sec to raise temperature to boiling point

Consider that 168.0 J of work is done on a system and 305.6 J of heat is extracted from the system. In the sense of the first la
Ilia_Sergeevich [38]

To solve this problem we must resort to the Work Theorem, internal energy and Heat transfer. Summarized in the first law of thermodynamics.

dQ = dU + dW

Where,

Q = Heat

U = Internal Energy

By reference system and nomenclature we know that the work done ON the system is taken negative and the heat extracted is also considered negative, therefore

W = -168J \righarrow  Work is done ON the system

Q = -305.6J \rightarrow Heat is extracted FROM the system

Therefore the value of the Work done on the system is -158.0J

aleksandrvk [35]

Answer:

Explanation:

a) I = ½mR² = ½(19)(0.15²) = 0.21375 kg•m²

b) τ = Fnet(r) = (25 - 12)(0.15) = 1.95 N•m

c) CCW

d) a = τ/I = 1.95 / 0.21375 = 9.12280701... = 9.1 rad/s²

e) CCW
