B is what u are looking for something specific
In 1869, the Fifteenth Amendment prohibited government from denying a citizen the right to vote based on that citizen's "race, color, or previous condition of servitude". Ratification of the Nineteenth Amendment gave women the right to vote in time to participate in the Presidential election of 1920.The Twenty-sixth Amendment, ratified in 1971, required all states to set a voting age no higher than eighteen. District of Columbia citizens had voting rights removed in 1801 by Congress, when Congress took control of that portion of Maryland. Congress incrementally removed effective local control or home rule by 1871. It restored some home rule in 1971, but maintained the authority to override any local laws. Washington, D.C., does not have full representation in the U.S. House or Senate. The Twenty-third Amendment, restoring U.S. Presidential Election after a 164-year-gap, is the only known limit to Congressional "exclusive legislature" from Article I-8-17, forcing Congress to enforce for the first time Amendments 14,15,19, 24, and 26. Amendment 23 gave the District of Columbia three electors and hence the right to vote for President, but not full U.S. Congressmembers nor U.S. Senators. In 1978, Congress proposed a constitutional amendment that would have restored to the District a full seat for representation in the Congress as well. This amendment failed to receive ratification by sufficient number of states within the seven years required.
<span>Answer:
For the old car:-
By v = u + at
=>v = 0 + 10a
=>a = v/10 m/s^2
By s = ut + 1/2at^2
=>s = 0 + 1/2 x v/10 x 10 x 10 = 5v
Thus F = ma
=>F = m x v/10 = mv/10
=>P(old) = F x s = mv/10 x 5v = 1/2mv^2 ------------------------(i)
For new car:-
By v = u + at
=>6v = 0 + 10a
=>a = 3/5v
By s = ut + 1/2at^2
=>s = 0 + 1/2 x 3/5v x 10 x 10
=>s = 30v
By F = ma
=>F = m x 3/5v = 3mv/5
Thus P(new) = F x s = 3mv/5 x 30v = 18mv^2 ------------------------------(ii)
=>P(new) : P(old) = 18mv^2 : 1/2mv^2 = 36 : 1</span>
