Lera25 [3.4K]3 years ago
5 0

Answer:

1.25 m/s2

Explanation:

m = 1000 kg

F = 800 N

F = m*a, which means ==> a = F / m

Fill in the formula and you get:

a = 1000 / 800 = 1.25 m/s2

PtichkaEL [24]

All of that fluff at the beginning is interesting, but completely irrelevant
to the question.  The question is just asking for the mass of an object
that weighs 3.6N on Earth.

                           Weight = (mass) x (acceleration of gravity)

                              3.6N = (mass) x (9.8 m/s²)

Divide each side
by  9.8 m/s :           Mass = 3.6N / 9.8 m/s² = <em>0.367 kilogram</em> (rounded)

What is the approximate value of the gravitational force between a 73 kg astronaut and a 7.1×104 kg spacecraft when they're 89 m
Luden [163]

Answer:

F = 4.3671 * 10^{-8}\ Newtons

Explanation:

The gravitational force between two corpses is given by the following equation:

F = GMm/d^2

Where F is the force, G is the gravitational constant

(G = 6.67408*10^{-11}\ m^3kg^{-1}s^{-2}), M and m are the masses of the corpses and d is the distance between them.

So we have that:

F = 6.67408*10^{-11} * 7.1*10^4 * 73/89^2

F = 4.3671 * 10^{-8}\ Newtons

You place ammonium nitrate crystals in water and stirred. As you do so, the container becomes cold to the touch. This an example
ankoles [38]

The process of flask becoming cold is due to endothermic reaction.

Answer: Option B

<u>Explanation:</u>

So two kinds of heat transfer can be possible in any chemical reaction. If the sample is considered as system and the sample container is considered as the surrounding, then heat transfer can occur between them.

If the heat is transferred from the surrounding to the system , then it is an endothermic reaction. And in those cases, the sample holder will be becoming colder. This is because the heat from the surrounding that is the container will be utilized to complete the reaction.

While when there is transfer of heat from the system to surrounding , it will be exothermic reaction and the beaker will be getting hot in this process. So in the present case, the container is becoming cold because of occurrence of endothermic process.

A solid object has a mass of 104 kg and a volume of 1,278 m3. What is its density?
MrMuchimi
The density is 81.4 g/m3. Before you start plugging numbers into the density formula (D=M/V), you should convert 104 kg to grams, which ends up being 104,000 grams. Then you can plug in the 104,000 grams and 1,278 m3 into the formula. When you divide the mass by the volume, you get a really long decimal, which you can round to 81.4 g/m3, or whatever place your teacher wants you to round to.
