B, heat, is the correct answer. Heat is represented by a capital q in thermodynamic equations.
Answer: Yes
Explanation:
A ruber band can be described by his mas, M, the spring constant K, and his rest radius, wich is the radius of the circular rubber band when there is no force applied to it, so yes, a uniform thin circular rubber band of mass M and spring constant k has an original radius R
Metals are not brittle so it can’t be the first one or the third one, both metalloids and metals are shiny so it can’t be the second one. Therefore, it would be the last one because both metalloids and metals are shiny and both are solids at room temperature because it is not a high enough melting point.
ANSWER: Both are shiny and are solid at room temperature.
Answer:
Explanation:
Given:
time (t = 10.0 sec)
power = 150 Hp
We need to find the energy transformed by a 150 Hp engine in 10 s.
Solution:
First we convert 150 Hp in watt.
So, power (p = 111900 watt)
We know that, if we multiply power by time, we get energy transform by engine.
-----------(1)
Where:
P ⇒ power.
E ⇒ Energy.
t ⇒ time.
Substitute p = 111900 watt and t = 10 s in equation 1.
Therefore, a 150 Hp engine could transform 1,119,000 joules energy in 10 s.
