When you are sitting in a car that is turning around a circle, you feel your body is being thrown outward. However, your physics

Degger [83]

Answer:

Explanation:

Centripetal force acts towards the center of the circle. However, our body is not attached to the car, it is only kept in the car. Therefore, when an external force acts on the car, inertia acts on the body due to the sense that it will try to remain in the same state.

Although the car takes the turn, but due to the inertia, the body will try to move forward; but since the seat belts are on, it is enforced to move with the car in a circular motion

Some volcanic eruptions are quiet and others are violent what causes this difference?

Step2247 [10]

Volcanoes that produce explosive eruptions tend to have thicker, more viscous magma, and a greater volume of gas. <span>Different types of volcanoes tend to produce different types of eruptions. Shield volcanoes, those with broad, gentle slopes, produce the quietest eruptions. The main difference is the shape of the volcano.

Which of the following will increase the resistance of a wire? Check all that apply. Check all that apply. Increasing the cross-

Lostsunrise [7]

Correct answers:

- Increasing the resistivity of the material the wire is composed of will increase the resistance of the wire.

- Decreasing the cross-sectional area of the wire will increase the resistance of the wire.

- Increasing the length of the wire will increase the resistance of the wire.

Explanation:

The resistance of a wire is given by:

$R=\rho \frac{L}{A}$

where

$\rho$ is the resistitivity of the material

L is the length of the wire

A is the cross-sectional area of the wire

From the formula, we can notice that:

- The resistance (R) is directly proportional to both the resistivity ( $\rho$ ) and the length of the wire (L), so when one of these quantities increases, the resistance will increase as well

- The resistance (R) is inversely proportional to the cross-sectional area (A), therefore when the resistance increases when the cross-sectional area decreases.

Based on these observations, the correct statements are:

- Increasing the resistivity of the material the wire is composed of will increase the resistance of the wire.

- Decreasing the cross-sectional area of the wire will increase the resistance of the wire.

- Increasing the length of the wire will increase the resistance of the wire.

Distinguish between average speed and average<br>velocity

Butoxors [25]

Answer:

The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.
