Explain subduction simply.

Answers

Answer 1

Answer:

Answer:

Subduction is when two tectonic plates meet. One of the plates is pushed under the other into the Earth's mantle. Subduction causes the most powerful earthquakes in the world. Earthquakes caused by subduction can lead to tsunamis.

a long wire carries a current toward the north in a magnetic field that is directed vertically downward. what is the direction of the magnetic force on the wire?

Answers

The magnetic force on the wire will be directed to the east.

The direction of the magnetic force on the long wire carrying a current toward the north in a magnetic field directed vertically downward would be to the east.

This is because of the right-hand rule, where if you point your right thumb in the direction of the current and your fingers in the direction of the magnetic field, the resulting force would be perpendicular to both, pointing to the east in this case.
When a long wire carries a current toward the north in a magnetic field that is directed vertically downward, you can determine the direction of the magnetic force on the wire using the right-hand rule.

Step 1: Point your right thumb in the direction of the current (north).
Step 2: Curl your fingers in the direction of the magnetic field (downward).
Step 3: The direction of the force on the wire will be the direction your palm is facing.

Following these steps, the magnetic force on the wire will be directed to the east.

Which of the following graphs best shows the velocity v of the clay ball from when it is dropped until it hits the ground?

Answers

Answer:

The correct option is;

Explanation:

The given information is that a clay ball is dropped from a certain height.

Therefore, the clay ball has an initial potential energy and zero kinetic energy

Which gives that the initial velocity of the clay ball = 0

As the potential energy is converted into kinetic energy, the velocity of the clay ball increases

However, if the direction of measurement of the velocity is opposite to the direction in which the clay ball is falling, the velocity of the ball progressively increases negatively as shown in option C

Final answer:

A graph of the clay ball velocity from the moment it's dropped until it hits the ground would be a straight line with a negative slope. This is because the velocity increases in the negative direction as the ball accelerates downwards under the force of gravity.

Explanation:

The graph showing the velocity v of a clay ball from when it's dropped until it hits the ground would look like a diagonal line descending from left to right with a negative slope. This is because the moment the clay ball is dropped, it starts accelerating downwards under the force of gravity. Therefore, its velocity increases in the negative direction, making the velocity-time graph a straight line with a negative slope. The slope represents the acceleration due to gravity.

During a baseball game, a baseball is struck at ground level by a batter. The ball leaves the baseball bat with an initial speed v0 = 38 m/s at an angle θ = 34° above horizontal. Let the origin of the Cartesian coordinate system be the ball's position the instant it leaves the bat. Air resistance may be ignored throughout this problem.

Answers

Answer:

The horizontal distance is 136.6 m.

Explanation:

Given that,

Initial speed = 38 m/s

Angle = 34°

Suppose, Calculate the horizontal distance $x_(max)$ in meters the ball has traveled when it returns to ground level.

We need to calculate the horizontal distance

Using formula of range

$R=(v_(0)^2\sin(2\theta))/(g)$

Where, v= speed

g = acceleration due to gravity

Put the value into the formula

$R=((38)^2\sin(2*34))/(9.8)$

$R=136.6\ m$

Hence, The horizontal distance is 136.6 m.

When a charged body is brought close to an uncharged body without touching it, a(n) _______________ charge may result on the uncharged body. When a charged body is brought into contact with an uncharged body and then is removed, a(n) _______________ charge may result on the uncharged body.

Answers

Explanation:

When a charged object is brought near a neutral object without touching each other a charge arises on the neutral object. This method of charge development is known as induced charge.

On the other hand, when a charged object touches a neutral object and then the charged object is removed will lead to the development of a charge on the neutral object. This charge is known as residual charge.

Thus, we can conclude that when a charged body is brought close to an uncharged body without touching it, an induced charge may result on the uncharged body. When a charged body is brought into contact with an uncharged body and then is removed, a residual charge may result on the uncharged body.

A car travelling at 32 m/s decelerates at a rate of 6 m/s ^ 2 over 4 secondsWhat is the final velocity the car

Answers

Answer:

v=8m/s

Explanation

The initial velocity, u, of the car=32m/s

Since the car has decelerated, we negate the acceleration

This implies that,

$a=-6m{s}^( -2)$

Time,t=4s

Let v be the final velocity,

using the relation,

$a = (v - u)/(t)$

We obtain the below by substitution

$- 6= (v - 32)/(4)$

By cross multiplying we obtain,

$- 6 * 4 = v - 32$

$- 24=v-32$

$- 24+32=v$

v=8m/s
