A) they have no effect on air temperature over land on the coast is False

Explanation:

warm and cold ocean currents can influence the coastal areas only when the air is blown into the land from the sea.
the temperature over the land increases when warm ocean currents heat the air above the ocean.
the temperature over the land decreases when cold ocean currents cool the air above the ocean and can bring colder winds to the coastal regions.
so, ocean currents play a major role in regulating the air temperature over land on the coastal region.

$\huge\red {\underline { \overline{ \bf \mid\: \: \: ↓ANSWER↓ \: \: \mid}}}$

Explanation:

Snell's law (also known as Snell–Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.

Q.4. What is the kinetic energy of a 10 kg car that is moving 4 m/s?

kodGreya [7K]

An object of mass $10 \mathrm{~kg}$ is moving with a uniform velocity of $4 \mathrm{~ms}^{-1}$ . The kinetic energy possessed by the object is $80 \mathrm{~J}$ .

Given:

Mass of an object $=10 \mathrm{~kg}$

Velocity $=4 \mathrm{~ms}^{-1}$

Kinetic Energy $=1 / 2 \times$ Mass of Object $\times(\text { Velocity })^{2}$

$\Rightarrow$ Kinetic Energy $=1 / 2 \times 10 \times 4 \times 4$

$\Rightarrow$ Kinetic Energy $=\underline{80 \mathbf{J}}$

What is Kinetic Energy?

In physics, an object's kinetic energy is the energy it has as a result of its motion.
It is defined as the amount of work required to accelerate a body of a given mass from rest to a certain velocity.
The body retains its kinetic energy after gaining it during acceleration until its speed changes.
Kinetic energy is present in a speeding bullet, a walking human, and electromagnetic radiation such as light. The energy associated with the continual, random bouncing of atoms or molecules is another type of kinetic energy.

The closest star to our solar system is Alpha Centauri, which is 4.12 × 10^16 m away. How long would it take light from Alpha Ce

bonufazy [111]

Time = (distance) / (speed)

Time = (4.12x10^16 m) / (3 x10^8 m/s)

Time = 1.37 x 10^8 seconds

Divide the seconds by 86,400 to get days. Then divide the days by 365 to get years.

Time = about 4.35 years
