Answer:

Vaporization.

Explanation:

When we heat or raise the energy of any sample, it evaporates. Evaporation is known as a form of Vaporization. When some sample evaporates, then they basically take in heat and when the sample condenses, it cools down by giving out the heat into the surrounding, atmosphere and the energy goes into the atmosphere.

An example of evaporation is the rain cycle. Where it's cooler, water on earth's surface evaporates and travels up through the atmosphere. The cool temperature causing the vapor to condense and back into water drops. When the cloud becomes saturated, the droplets fall to the ground in the form of rain.

This is the constructive or destructive overlap of waves.

natima [27]

Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium.

Two long, straight wires are parallel and are separated by a distance of d = 0.210 m. The top wire in the sketch carries current

love history [14]

Answer:

$1.88\cdot 10^{-5} T$ , inside the plane

Explanation:

We need to calculate the magnitude and direction of the magnetic field produced by each wire first, using the formula

$B=\frac{\mu_0 I}{2\pi r}$

where

$\mu_0$ is the vacuum permeability

I is the current

r is the distance from the wire

For the top wire,

I = 4.00 A

r = d/2 = 0.105 m (since we are evaluating the field half-way between the two wires)

$B_1 = \frac{(4\pi\cdot 10^{-7})(4.00)}{2\pi(0.105)}=7.6\cdot 10^{-6}T$

And using the right-hand rule (thumb in the same direction as the current (to the right), other fingers wrapped around the thumb indicating the direction of the magnetic field lines), we find that the direction of the field lines at point P is inside the plane

For the bottom wire,

I = 5.90 A

r = 0.105 m

$B_2 = \frac{(4\pi\cdot 10^{-7})(5.90)}{2\pi(0.105)}=1.12\cdot 10^{-5}T$

And using the right-hand rule (thumb in the same direction as the current (to the left), other fingers wrapped around the thumb indicating the direction of the magnetic field lines), we find that the direction of the field lines at point P is also inside the plane

So both field add together at point P, and the magnitude of the resultant field is:

$B=B_1+B_2 = 7.6\cdot 10^{-6} T+1.12\cdot 10^{-5}T=1.88\cdot 10^{-5} T$

And the direction is inside the plane.

A firecracker sitting on the ground explodes into two pieces. Immediately after the explosion, one of the pieces has momentum of

Misha Larkins [42]

Answer:

other part will move with momentum 0.5 kg m/s towards west

Explanation:

As we know that the during the explosion event the time interval is very small and there is no impulsive force on the firecracker during this time

so here we can say that the momentum will remains conserved during the this event

now if the initial momentum of the firecracker is zero

then the final momentum must be zero

so here we can say

$P_1 + P_2 = 0$

$P_1 = 0.5 kg m/s$ towards east

now from above equation

$P_2 = - P_1 = -0.5 kg m/s$

so the other part will move with momentum 0.5 kg m/s towards west

Why sound heard better at night than at day?

vodomira [7]

Answer:

it is because it is quieter at night than in the daytime. Therefore it is easy to hear the sound far away. However, it is only one of the reasons. Actually, sound transmits farther at night may be related to refraction of sound waves! First, sound is the vibration of air, and it is a kind of wave motion.
