Answer:

The speed of elevator fast and slows down shows through the diagram.

Explanation:

Given that,

Amanda has just entered an elevator. The elevator rises and stops at the third floor.

Let us consider the elevator at rest then the speed will be zero.

When elevator start from rest then the speed increases with constant acceleration and near the third floor it slow down with constant deceleration and finally becomes at rest at third floor.

We need to draw the diagram distance and time

Using given data,

First, the displacement A to B will be increases fastly and B to C the displacement increases slowly slowly.

Hence, The speed of elevator fast and slows down shows through the diagram.

Which group was guaranteed voting rights by the Fifteenth Amendment?

castortr0y [4]

Explanation:

The 15th Amendment to the U.S. Constitution granted African American men the right to vote by declaring that the "right of citizens of the United States to vote shall not be denied or abridged by the United States or by any state on account of race, color, or previous condition of servitude." Although ratified on February 3, 1870, the promise of the 15th Amendment would not be fully realized for almost a century. Through the use of poll taxes, literacy tests and other means, Southern states were able to effectively disenfranchise African Americans. It would take the passage of the Voting Rights Act of 1965 before the majority of African Americans in the South were registered to vote.

Juliette [100K]

<u>Out of all given choices, the following statements are true:</u>

An ammeter is used to measure current.
A voltmeter is used to measure voltage.
A voltmeter must be placed in parallel with a resistor to measure the voltage across the resistor.

Options A, E, and F

<u>Explanation:</u>

An instrument by which the current in a circuit is measured is called ammeter whereas an instrument in which voltage is measured in a circuit is called a voltmeter . The ammeter is placed in series with the resistor while the voltmeter is placed in parallel with the resistor.

For the option B, since the ammeter must be placed in series with the resistor to measure current, it is false. Option C is false because an ammeter has zero internal resistance. Option D is also false because a voltmeter has a high internal resistance and is actually infinite.
