Question

U1=0 м/сu2=4000 м/сm0=9,1•10-31кгn=1e=1,6•10-19кмu-?​

Answer 1

Ответ:

U, u — двадцать первая буква базового латинского алфавита. В латинском алфавите называется «у»; такое же или почти такое название сохранилось в итальянском, немецком и многих других языках. Но в английском алфавите эта буква называется «ю».

я точно не поняла что надо u 12

Answer 2

To find the unknown quantity "u," you can use the conservation of momentum equation:

m1 * u1 + m2 * u2 = m0 * u

Where:

• m1 is the mass of the first object,
• u1 is the initial velocity of the first object,
• m2 is the mass of the second object,
• u2 is the initial velocity of the second object,
• m0 is the mass of the combined system after the collision (which is still m0 since there are no external forces involved),
• u is the final velocity of the combined system after the collision.

You provided the following values:

m1 = 0 kg (assuming this is the mass of the first object) u1 = 0 m/s (initial velocity of the first object) m2 = 0 kg (assuming this is the mass of the second object) u2 = 4000 m/s (initial velocity of the second object) m0 = 9.1 x 10^-31 kg (mass of the combined system, which seems to be related to subatomic particles) n = 1 e (which is 1.6 x 10^-19 C)

First, we need to find the mass of the first and second objects. It seems that you haven't provided the mass values for these objects. If you have the mass values, please provide them, and I can calculate the final velocity (u) for you.
