Which material would be best to use for heating up food? a) aluminum b) ceramic c) foam d) plastic eliminate

Correct answer is option A (Aluminum)

Explanation:

 option A is correct because aluminum can be used both on stove and in Electric oven and it does not melt on heating and also aluminum is not harmful for health.

option B

Ceramic can only be used in microwave but it cannot be used on stove. If we use ceramic on stove it will break.

option C

Foam cannot be used on stove and it is not safe to use in microwave.

Option D

We cannot used plastic on stove because on heating plastic will melt and in microwave the chemicals which are used to create will contaminate the food.

b

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
