I) Kinetic Energy

Physics
1 answer:
MAXImum [283]3 years ago
7 0

Answer: D

Explanation: In the energy conversion of a nuclear power plant, uranium acts as nuclear fuel, so, Intranuclear Potential Energy (uranium) is converted to thermal energy which is Kinetic Energy (high-pressure steam) which is converted to mechanical energy that is,

Kinetic Energy (spinning turbine) then to Kinetic Energy (generator) and finally Kinetic Energy (electricity in

transmission lines)

Therefore, the best option is D which is

D. III, I, II, V, IV

A spring is hung from the ceiling. When a block is attached to its end, it stretches 2.5 cm before reaching its new equilibrium
Brums [2.3K]

Answer:

0.99Hz

Explanation:

Using F= -mx ( spring force)

At equilibrium the gravitational force will be balanced by the spring force so mg= kx

K= mg/ 0.25 N/m

But

Frequency f= 1/2pi √g/0.25

Frequency is 0.99Hz

Una persona A tiene cierta cantidad de masa y una persona B tiene la mitad de masa de la persona A ¿como es el peso de B respect
musickatia [10]

Answer:

El peso de la persona B es la mitad del peso de la persona A.

Explanation:

El peso de la persona B puede calcularse con la siguiente ecuación:

P_{B} = m_{B}g   (1)

En donde:

m_{B}: es la masa de la persona B

g: es la gravedad

Dado que la persona B tiene la mitad de la masa de la persona A, tenemos:

m_{B} = \frac{m_{A}}{2}  (2)

En donde:

m_{A}: es la masa de la persona A

Al introducir la ecuación (2) en (1) nos queda:

P_{B} = \frac{m_{A}}{2}g   (3)

Sabemos que el peso de la persona A está dado por:

P_{A} = m_{A}g   (4)

Entonces, al introducir la ecuación (4) en (3) tenemos:

P_{B} = \frac{P_{A}}{2}

Por lo tanto, el peso de la persona B es la mitad del peso de la persona A.

which component of the Star Wars movies is possible according to our current understanding of physics?
Alex777 [14]
 Star Wars uses science and technology<span> in its settings and storylines, although its main focus is not necessarily on science. The component of the Star Wars movies which is possible according to our current understanding of physics is their interstellar travel.
</span><span>The behavior of spacecraft engaged in battle is another aspect of the films is troubling the scientists. According to them,  when hit in space by a blaster, the crafts should continue moving in the same direction as the impact rather than falling downwards as the effects of gravity would not apply while in orbit. </span>

A positive charge is placed midway between two equal negative charges. what is the direction of the total force on the positive
iragen [17]

The total force is the vector sum of the individual forces. The force from either electron has the same magnitude at the midpoint, but the directions of the forces are opposite, so the sum of the two forces is zero. I hope this helps! Thanks
