If an object with more mass is pushed with the same force as an object with less mass the object with more mass will accelerate?
expeople1 [14]

Answer:

smaller acceleration, so lower change in velocity

Explanation:

To answer this question we examine the equation that relates mass with force and with acceleration: F=m*a.

Since we want to know what happens to the acceleration, we solve for it in the equation: a=\frac{F}{m}

Notice that we are asked what happens when the force applied is the same, but now it is applied in an object with more mass (M).

We therefore would have to compare our initial form:

a=\frac{F}{m} with the new one: a=\frac{F}{M} wher the denominator is a larger quantity, therefore making our division/quotient smaller. Then, we conclude that the acceleration will be smaller, and therefore the change in velocity of the object will be lower.

A 45-year-old man is meeting his doctor for his annual physical. He suffers from Type 2 diabetes and has a family history of cor
shutvik [7]

Answer:

The man is on the verge of having a heart attack or a stroke.

Explanation:

If he has a family history of coronary (heart) disease, it means it could normally affect. Normally here means without anything aggravating it. It's already in his lineage so he could have it.

Now, he's past middle age - he's 45. He's past the growing stages of life. His organs are fully developed herefore.

Now also, he suffers from Type 2 diabetes. Although this is sometimes milder than Type 1 diabetes, it increases the risk of having a heart disease or a stroke!

Soda, especially sweetened one, is not to be taken too often because it can cause Diabetes Mellitus. For a diabetes patient, this should be a "no-go-area". Taking this constantly (everyday at work) will now put this 45-year-old man in harm's way.

He is no more at risk of having complications but already on the path to a heart disease or a stroke.

Which of the following best models the changes in energy of a blackbody radiator?
Pani-rosa [81]
We have that a blackbody radiator either constantly absorbs energy or constantly emits energy, depending on its surroundings. In this case, the energy is continuously and smoothly decreasing, thus it cannot be like B and C.
The energy loss or gain is also monotonous, it has the same direction; a radiator cannot gain energy at some point and then lose some. Hence, it does not resemble a wave either. The most appropriate model is the ramp. Energy is constantly emitted to surroundings and it decreases monotonically.
