Answer;
The temperature change for the second pan will be lower compared to the temperature change of the first pan
Explanation;
-The quantity of heat is given by multiplying mass by specific heat and by temperature change.
That is; Q = mcΔT
This means; the quantity of heat depends on the mass, specific heat capacity of a substance and also the change in temperature.
-Maintaining the same quantity of heat, with another pan of the same mass and greater specific heat capacity would mean that the change in temperature would be much less lower.
2 J / 4 C = 1/2 joule per coulomb.
That's 1/2 volt.
Answer:
Explanation:
To calculate the momentum of a moving object multiply the mass of the object times its velocity. The symbol for momentum is a small p. So, the momentum of the object is calculated to be 8.0 kg-m/s. Note the unit for momentum.
Answer:
Explanation:
The centripetal acceleration of the child, which is moving by uniform circular motion, is given by
where
v = 5 m/s is the tangential speed of the child
r = 1.2 m is the radius of the circular path
Substituting the numbers into the equation, we find
