The formula for force is F=ma. Because weight is a measure of force, then we can substitute the weight of the meteor, 3204 N, for F in the the equation for force. We also know that the acceleration of gravity on Earth is 9.8 m/s^2. To find the mass, simply divide both sides of the equation by the value of acceleration to get
![m = \frac{f}{a} = \frac{3204}{9.8} = 326.9](https://tex.z-dn.net/?f=m%20%3D%20%20%20%5Cfrac%7Bf%7D%7Ba%7D%20%20%3D%20%20%5Cfrac%7B3204%7D%7B9.8%7D%20%20%3D%20326.9)
Therefore, the value of the mass of the meteor is 326.9 kg.
This answer would be heat capacity
Answer:
1.The Aluminum block
2.its surroundings absorb energy from it.
Explanation:
In this question it is important to remember that density of an object is the mass of that object divided by its volume.
The expression applied here is density=mass/volume
Given that the mass is constant,lets say mass= m=1g
and density of aluminum=2.7g/cm³ and that of iron is 7.8 g/cm³ then volume=?
Volume=mass/density
Volume of aluminum= 1/2.7 =0.3704 cm³
Volume of iron = 1/7.8 =0.1282 cm³
Here we see volume of Aluminum block is the largest.
2.As water in an ice cube tray freezes, its surroundings absorb energy from it.When the water freezes, latent heat of freezing is given out to the surrounding.When water is freezing, it stays at a constant temperature of 0°C, the heat energy released ensures that there is no cooling past 0 °C.
Answer: Option (B) is the correct answer.
Explanation:
A change which brings change in composition of atoms of a substance to result in the formation of new substances is known as a chemical change.
Therefore, in a chemical change new substances are formed which have different properties as compared to their reactants.
For example, ![2Na + Cl_{2} \rightarrow 2NaCl](https://tex.z-dn.net/?f=2Na%20%2B%20Cl_%7B2%7D%20%5Crightarrow%202NaCl)
Thus, we can conclude that during all chemical changes atoms rearrange to form new substances.
