Answer:
0.25 J
Explanation:
Given that
Force on the spring, F = 30 N
Natural length of the spring, l1 = 20 cm = 0.2 m
Final length of the spring, l2 = 35 cm = 0.35 m
Extension of the spring, x = 0.35 - 0.2 = 0.15 m
The other extension is 40 - 35 cm = 5 cm = 0.05 m
Work done = ?
Considering Hooke's Law of Elasticity.
We're told that the spring stretches through 15 cm, and thereafter asked to find the work done in stretching it through 5 cm
The question is solved in the attachment below
Answer: Kinetic theory or kinetic theory of gases attempts to explain overall properties of gases, such as pressure, temperature, or volume, by considering their molecular composition and motion. The theory basically states that pressure is not caused by molecules pushing each other away, like earlier scientists thought.
Explanation:
Answer:
<h2>15 m</h2>
Explanation:
The distance covered can be found by using the formula
f is the force
w is the workdone
From the question we have
We have the final answer as
<h3>15 m</h3>
Hope this helps you
Answer:
Low specific heat values
Explanation:
Metals are generally known to have very low specific heat values because they are good conductors. It simply implies that it takes very little heat energy to cause a rise in temperature of metals compared to other substances.
- Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by 1°C.
A material that can conduct heat i.e allows it to flow readily and thereby, will require little amount of heat.
Average acceleration is the change in velocity divided by an elapsed time.
