A1.0-kg block and a 2.0-kg block are pressed together on a horizontal frictionless surface with a compressed very light spring between them. they are not attached to the spring. after they are released and have both moved free of the spring
the lighter block will have more kinetic energy than the heavier block.
the magnitude of the momentum of the heavier block will be greater than the magnitude of the momentum of the lighter block.
the heavier block will have more kinetic energy than the lighter block.
both blocks will both have the same amount of kinetic energy.
both blocks will have equal

Explanation:

Remember that momentum is not the same as energy or speed. Momentum or quantity of motion can be defined as the product between the mass of the object and its speed. This means, if the object is heavy, it has a lot of mass, therefore it will have more momentum. On the other hand, if it's a light object, it won't have greater momentum.

So, in this context both blocks have different mass, and according to Momentum's definition, the block with more mass, will have more momentum.

Therefore, the answer is the second option.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
