A 70.0 kg ice hockey goalie, originally at rest, has a 0.170 kg hockey puck slapped at him at a velocity of 33.5 m / s . Suppose

Sergeeva-Olga [200]

Answer:

Final velocity of both goalie & puck = 0.018116 m/s

Explanation:

M1U1 + M2U2 = (M1+M2)V

70 x 0 + 0.17 x 33.5 = (70+0.17)V

V = 0.08116m/s

Before leaving the house in the morning, you plop some stew in your slow cooker and turn it on Low. The slow cooker has a 160 Oh

guajiro [1.7K]

Answer:

Total charge flow through the cooker is 21600 C

Explanation:

As we know that the current flow through the cooker is given by Ohm's law

here it is given as

$V = i R$

$i = \frac{V}{R}$

$i = \frac{120}{160}$

$i = \frac{3}{4} A$

now the charge flow through it is given as

$Q = i t$

total time is t = 8 hours

$Q = \frac{3}{4}(8 \times 60 \times 60)$

$Q = 21600 C$

Se tienen 500g de alcohol etílico a una temperatura de -40 °C ¿Cuánto calor se necesita para transformarlo a vapor a una tempera

Feliz [49]

The question is: You have 500g of ethyl alcohol at a temperature of -40 ° C. How much heat is needed to transform it into steam at a temperature of 150ºC?

Answer: 233700 J heat is needed to transform ethyl alcohol into steam at a temperature of $-40^{o}C$ to $150^{o}C$ .

Explanation:

Given: Mass = 500 g

Initial temperature = $-40^{o}C$

Final temperature = $150^{o}C$

The standard value of specific heat of ethyl alcohol is $2.46 J/g ^{o}C$ .

Formula used to calculate the heat energy is as follows.

$q = m \times C \times (T_{2} - T_{1})$

where,

q = heat energy

m = mass of substance

C = specific heat

$T_{1}$ = initial temperature

$T_{2}$ = final temperature

Substitute the values into above formula as follows.

$q = m \times C \times (T_{2} - T_{1})\\= 500 g \times 2.46 J/g^{o}C \times [150 - (-40)]^{o}C\\= 233700 J$

Thus, we can conclude that 233700 J heat is needed to transform ethyl alcohol into steam at a temperature of $-40^{o}C$ to $150^{o}C$ .

Ammonia is a weak base because produce ____ ion in solution?

AnnZ [28]

Ammonia is a weak base because it produces ammonium and hydroxide ions. Weak bases are so called weak because in the solution, these bases do not fully convert itself into hydroxide ions or in other words, it does not fully ionize in the solution.
