Answer:

Sample Response: Different objects contain different amounts of matter, even if they are the same size. Therefore, two objects of the same size can have different masses.

Hi I know im late on this but for people who are looking for the answer.

Answer:
The statement is not correct.

Reason:
If two objects have the same mass, their respective densities determine their volumes.
By definition,
density = mass/volume.
or volume = mass/density.

Therefore if two objects have the same mass, the mode dense object (with higher density) will occupy less volume than the other object.

Tanzania [10]

While ice melts, it remains at 0 °C, and the liquid water that is formed with the latent heat of fusion is also at 0 °C. The heat of fusion for water at 0 °C is approximately 334 joules per gram, and the heat of vaporization at 100 °C is about 2,230 joules per gram. So it will be C

Which of the following is not in our sun's future?
fenix001 [56]
The answer would not be A, because if the sun converts into a giant, the star will eventually become a white dwarf due to the fact it was previously a giant. Thus the answer would be B, since the sun does not become a supergiant.

The Nardo ring is a circular test track for cars. It has a circumference of 12.5 km. Cars travel around the track at a constant
KIM [24]

Answer: 50 km, 0, 27.78 m/s

Explanation:

Given

Circumference of the track is 12.5\ km

Speed of car is 100\ km/h

Car drives for 30\ \text{minute}\ or\ 0.5\ hr

(a)Distance traveled is

\Rightarrow D=100\times 0.5\\\Rightarrow D=50\ km

(b)displacement of the car

It can be observed that 12.5 is a multiple of 50, that is, 50 km can be interpreted as 4 complete rounds of the track.

Therefore, the displacement of the car is zero.

(c)To convert kmph to m/s, multiply the entity by \frac{5}{18}

\Rightarrow 100\times \dfrac{5}{18}\\\\\Rightarrow 27.78\ m/s

A train of mass 320000 kg accelerate uniformly from rest. It takes 57 s to travel a distance of 810 m in a straight line. Find t
Nastasia [14]

Answer:

160,000 N

Explanation:

Given:

m = 320,000 kg

v₀ = 0 m/s

a = constant

t = 57 s

Δx = 810 m

Find: Fnet

Apply Newton's second law:

∑F = ma

Fnet = ma

To find Fnet, we must first find the acceleration.

x = x₀ + v₀ t + ½ at²

810 m = 0 m + (0 m/s) (57 s) + ½ a (57 s)²

a = 0.50 m/s²

Fnet = (320,000 kg) (0.50 m/s²)

Fnet = 160,000 N
