Because of the differences in physical properties, the lithosphere is effectively detached from the asthenosphere, allowing layers to move separately.

<h3>What is Lithosphere?</h3>

The Lithosphere, the earth's powerful outer layer, lies over the weak Asthenosphere.
Under the lithosphere is the Asthenosphere, a hotter and weaker portion of the mantle.

The lithosphere is divided into roughly twenty-four smaller pieces, or lithospheric plates.
These plates are always moving.

<h3>What is the theory of plate tectonics?</h3>

According to the widely recognised scientific hypothesis known as plate tectonics, the Earth's lithosphere is made up of many sizable tectonic plates that have been steadily moving for nearly 3.4 billion years.

Across what potential difference does an electron have to be accelerated in order to reach the speed v=3e7 m/s?

zmey [24]

When an electron is accelerated through potential difference then the speed that it attain will be explained by energy conservation

here by energy conservation we can say that

change in kinetic energy of electron = electrostatic potential energy gained through given potential difference

kinetic energy is given as

$KE = \frac{1}{2}mv^2$

electrostatic potential energy is given as

$PE = qV$

now by energy conservation

$qV = \frac{1}{2}mv^2$

given that for electron

$m = 9.1 * 10^{-31} kg$

$v = 3 * 10^7 m/s$

$q = 1.6 * 10^{-19} C$

now by plug in values

$1.6 * 10^{-19} * V = \frac{1}{2}*9.1* 10^{-31} *(3*10^7)^2$

$V = \frac{4.095 * 10^{-16}}{1.6 * 10^{-19}}$

$V = 2559.4 Volts$

So here it is accelerated through potential difference of 2559.4 Volts

3. How does the centripetal force change when

OLga [1]

Answer:

The centripetal force increases.

Explanation:

Centripetal force is given by $F_c=ma_c$ ; where $a_c=\frac{v^2}{r}$ .

Given these two equations, we can rewrite the formula for centripetal force as:

$F_c=m\frac{v^2}{r}$

As shown, radius is in the denominator, thus, a smaller radius would lead to a larger centripetal force.

The passengers are facing forward in the direction that the train is moving. What will happen to the passengers sitting on a tra

marysya [2.9K]

Passengers which are facing forward in the direction that train is moving, their bodies will move forward in application of sudden stop of train.

<h3>What is force of inertia?</h3>

Force of inertia is the force which acts in the opposite direction of the force of acceleration acting on the body.

Given infroamtion-

The passengers are facing forward in the direction that the train is moving.

The train comes to a sudden stop.

Lets see what happens step wise-

Here, the train in moving in the forward direction and the passengers are also facing forward in the direction that the train is moving.

Now the train comes to a sudden stop. By this sudden stop the train stops suddenly but all the object including the passengers is still travelling forward due to the inertia force.

Thus all the passenger will tend to move in the direction as they are still travelling.

Hence, passengers which are facing forward in the direction that train is moving, their bodies will move forward in application of sudden stop of train.
