For any force and any mass, the acceleration is always
(the strength of the force) divided by (the mass) .
If a force of 5 newtons is applied to a mass of 5 kg, the acceleration will be
(5 Newtons) / (5 kg) = <em>1 m/s²</em>
Answer:
Left to right and top to bottom
Explanation:
On the periodic table, the properties repeat from left to right and from top to bottom.
Periodic properties have a pattern from the top to the bottom or down a group or family.
Also, across the period from left to right, they also show a repeating pattern.
- Certain properties increase from left to right and decreases from top to bottom. E.g. electronegativity.
- Also, some properties decreases from left to right and increases from top to bottom e.g. atomic radius.
Answer:
if he is chasing his tail faster with each circle, then that would be acceleration, If not then no
Answer:
The work done by this engine is 800 cal
Explanation:
Given:
100 g of water
120°C final temperature
22°C initial temperature
30°C is the temperature of condensed steam
Cw = specific heat of water = 1 cal/g °C
Cg = specific heat of steam = 0.48 cal/g °C
Lw = latent heat of vaporization = 540 cal/g
Question: How much work can be done using this engine, W = ?
First, you need to calculate the heat that it is necessary to change water to steam:
Here, mw is the mass of water
Now, you need to calculate the heat released by the steam:
The work done by this engine is the difference between both heats:
