Answer:

Because electromagnetic waves can travel through empty space

Explanation:

The energy that is emitted from the sun is transferred to the earth in the form of radioactive waves. These waves are originated due to the vibration between the electric and magnetic fields. As this energy reaches the earth, it warms the earth's atmosphere, resulting in the transfer of heat energy in three possible ways namely the conduction, convection, and radiation.

This electromagnetic waves do not require any matter for the transmission of energy, and can easily travel in empty space from the core of the sun to the earth and other nearby planets. Whereas other types of waves cannot travel in space, so it is transferred in the form of electromagnetic waves only.

Suppose that a car traveling to the west (-x direction) begins to slow down as it approaches a traffic light. Which statement co
dalvyx [7]

Answer:

Its acceleration is positive

Explanation:

As the car is moving in the negative x-direction than after applying brake then there will be a decrease in the acceleration but in the opposite direction.

As decreasing acceleration consider to be negative but the car is moving in negative direction which means increasing acceleration is negative by sign convention but by applying brake acceleration decrease but in opposite direction than it will give positive value of acceleration.

This equation is used to calculate the properties of a gas under nonideal conditions.
goblinko [34]

Answer:

Van der Waal's equation

Explanation:

The Van der Waal's equation is use to calculate the properties of a gas under nonideal or real gases conditions.

(P + \frac{an^2}{V^2})(V-nb) = nRT .

Here P, V ,T ,n and R have usual meaning as in the ideal gas equation

that is PV=nRT

with the difference of constant a and b.  a and b are constants representing magnitude of intermolecular attraction  and excluded volume respectively respectively.

Value of x<br>Guys plz answer <br>and get marked as brainliest :)​
lakkis [162]

Answer:

80⁰

Explanation:

triangle AOB = 180

So, a = 50

triangle CAB = a+a+x=180

CAB = 50+50+X=180

CAB = X = 180-100

X=80

The resistance (R) of a copper wire varies directly as its length (L). Write this relation as a formula using k as the constant
Drupady [299]

Answer:

Explanation:

According to ohm's law current flowing in a conductor is directly proportional to the voltage applied across two end of conductor.

i.e. V\propto R

V=R I

where R=resistance

R\propto L

R\propto \frac{1}{d^2}

whee L and d are length and Diameter

thus R=k \frac{L}{d^2}

where k=constant of Variation
