Answer:
convection
Explanation:
The only way convection can only take place in liquids and gas.Since the marshmello is neither,convection is the least effective way
The answer should be D but if its not then im sorrry, idk
Answer:
The spring constant is 215.6 N/m.
Explanation:
Given that,
Distance = 39 cm
Compresses length = 29 cm
Mass = 2.2 kg
We need to calculate the distance
Using formula of distance

Put the value into the formula
We need to calculate the spring constant
Using formula of restoring force


Where, F = force
x = distance
Put the value into the formula


Hence, The spring constant is 215.6 N/m.
The closest answer i would go with is b, I'm not completely sure because I'm not sure what the question actually means because there could be any meaning
