Answer:

14.07W

Step-by-step explanation:

Mass of ice = 3.64 kg

Δt = 1 day

Initial temperature = 0°c

Final temperature = 0°c

Convert 1 day to seconds

1 * 24* 60 *60= 8.64 * 10^ 4 secs

Latent heat of fusion of water (Lf) = 334 * 10^3 J/kg

Average power = W/Δt

Energy that leaves and enters the system is heat energy. Therefore,

Average power = Q/Δt

Q= m(ice) * Lf

Q = 3.64 * 334 * 10^3

Power = (3.64 * 334 * 10^3)/ 8.64 * 10^4

= 1.21576 * 10^6 / 8.64 * 10^4

= 0.1407 * 10^2

= 14.07 W

The answer is A.

5 × 6 = 30
4 × 5 = 20
30 - 20 = 10

so there are ten more red apples so A is the answer

The sum of two numbers is 2. The sum of three times the larger and twice the smaller is 14. Find the numbers.
anzhelika [568]

For this case we have to:

x: Be the variable that represents the largest number

y: Be the variable that represents the smallest number

We propose a system of equations:

x + y = 2\\3x + 2y = 14

From the first equation we have to:

x = 2-y

Substituting in the second equation:

3 (2-y) + 2y = 14\\6-3y + 2y = 14\\6-y = 14\\-y = 14-6\\-y = 8\\y = -8

We look for the value of "x":

x = 2 - (- 8)\\x = 2 + 8\\x = 10

Answer:x = 10\\y = -8

What’s the y- intercept and x-intercept of y = 3/4x + 3
DochEvi [55]

Answer:

see below

Step-by-step explanation:

y = 3/4x + 3

To find the y intercept, let x =0 and solve for y

y = 0+3

The y intercept is 3

To find the x intercept, let y =0 and solve for y

0 = 3/4x+3

-3 = 3/4x

-3 *4/3 = 3/4x*4/3

-4 =x

The x intercept is -4
