The next step to take is to used the scientific method to explore the observations she has made in order to discover the facts behind her observations. She should ask questions about the hotness of the pavement and form an hypothesis to support her observation. She should then set up an appropriate experiment to confirm her hypothesis. After the conduction of the experiment, she should analyze her results and then draw a conclusion.<span />

An electric generator converts kinetic energy into which kind of energy?
dem82 [27]

Answer:

Electrical Energy

Explanation:

An electric generator is a device that changes kinetic energy to electrical energy through electromagnetic induction. Electromagnetic induction is the process of generating electric current with a magnetic field. ... Because the coil is rotating in a magnetic field, electric current is generated in the wire.

A wagon is rolling forward on level ground. Friction is negligible. The person sitting in the wagon is holding a rock. The total
Rudik [331]

Answer:

a) 0.41 m/s

b) 0.51 m/s

Explanation:

(a)

M = total mass of wagon, rider and the rock = 93.1 kg

V = initial velocity of wagon = 0.456 m/s

m = mass of the rock = 0.292 kg

v = velocity of rock after throw = 15.4 m/s

V' = velocity of wagon after rock is thrown

Using conservation of momentum

M V = m v + (M - m) V'

(93.1) (0.456) = (0.292) (15.4) + (93.1 - 0.292) V'

V' = 0.41 m/s

b)

M = total mass of wagon, rider and the rock = 93.1 kg

V = initial velocity of wagon = 0.456 m/s

m = mass of the rock = 0.292 kg

v = velocity of rock after throw = - 15.4 m/s

V' = velocity of wagon after rock is thrown

Using conservation of momentum

M V = m v + (M - m) V'

(93.1) (0.456) = (0.292) (- 15.4) + (93.1 - 0.292) V'

V' = 0.51 m/s

hallar un numero de dos cifras sabiendo que la suma de las cifras es 12 y que la primera de ellas es el triple de la segunda
Natali [406]

Answer:

93 o 39.

Explanation:

Hola.

En este caso, podemos resolver este problema por medio del planteamiento de las siguientes ecuaciones:

1. Definimos <em>x</em> como el primer dígito y <em>y</em> como el segundo, por lo tanto, como su suma es 12, escribimos:

<em>x</em> + <em>y</em> = 12

2. Ahora, dado que el primer dígito, x es el triple del segundo, escribimos:

<em>x</em> = 3 <em>y</em>

De este modo, podemos resolver para <em>y</em>:

3 <em>y</em> + <em>y</em> = 12

4 <em>y</em> = 12

<em>y</em> = 12 / 4

<em>y</em> = 3

Y para <em>x</em>:

<em>x</em> = 3 <em>y</em>

<em>x</em> = 3 * 3

<em>x</em> = 9

Así, el número puede ser 93 o 39.

¡Saludos!
