Mario and Patience are making cookies. They are ready to drop balls of dough on baking sheets. They have baking sheets made of t

reated glass, aluminum, stainless steel, and copper. The specific heats of these substances are: Treated glass = 0.75 J/g • °C Aluminum = 0.90 J/g • °C Stainless steel = 0.50 J/g • °C Copper = 0.39 J/g • °C Based on the specific heat values, which sheet is going to warm up the quickest, and, therefore, bake the cookies the fastest?

Answer:

Copper

Step-by-step explanation:

Heat = specific heat•mass•temperature change

Assuming that all sheets have the same mass and the oven transfers the same amount of heat to them, then the quantity: heat divided by mass is constant in all 4 cases.

Heat/mass = specific heat•temperature change = constant

As specific heats increase, temperature change of the material decrease, so that, their multiplication remains constant. Then, the material with the lowest specific heat will have the greatest temperature change, i. e., warms up quickest. Cooper is that material.

mart [117]

Answer:

Since the Frog makes a Jump every 10 seconds

   ( using the digits on a random number table )

  • It will take 7 jumps with 2 jumps in reverse direction i.e. either left or right for the frog to be off the board in 60 seconds
  • it will take 3 jumps in similar direction as well to get the frog off the board
  • also 5 jumps with 1 jump in the opposite direction is what it will take to get the frog off the board as well within the time frame of 60 seconds

Step-by-step explanation:

A frog sitting exactly in the middle of a board which is 5ft long : frog is 2.5 ft from the edge of the board

every 10 seconds the frog jumps ; L or R

If he jumps ; LLRLRL ( still on Board on the left-most square )

if he jumps ; LLRLL ( He is off the Board in fifty seconds )

Since the Frog makes a Jump every 10 seconds

   ( using the digits on a random number table )

  • It will take 7 jumps with 2 jumps in reverse direction i.e. either left or right for the frog to be off the board in 60 seconds
  • it will take 3 jumps in similar direction as well to get the frog off the board
  • also 5 jumps with 1 jump in the opposite direction is what it will take to get the frog off the board as well within the time frame of 60 seconds

A campus radio station surveyed 500 students to determine the types of music they like. the survey revealed that 199 like rock,
Ostrovityanka [42]
<span>There are 24 who like both rock and country. There are 8 who like all 3 types, and these eight have been counted under the 24. This means that the number who like rock and country but not jazz is 24 - 8 = 16.
We are given a total of 155 who like country. We subtract the 16 who like both rock and country, and are left with 139 people who like country but not rock. (It does not matter whether they like jazz or not).
The probability is 155 out of the total of 500, so 155/500 = 31/100 = 0.31.
