Explanation:
The heat transfer through brick wall is:
The heat flow in a 18.6-h period is:
<u>Answer:</u>
Both the objects A and B will have the same acceleration.
<u>Explanation
:</u>
The objects will have the same acceleration as both are under free fall condition. When objects are under the free fall condition, the only force that acts on the object is its weight.
Weight is the force acting on a body of some mass, and the formula for finding the weight of a body is- Weight = mass × acceleration due to gravity(g).
Therefore, here the different weight is due to the difference masses of both bodies, and not due to the different acceleration values.
We have that heat flow out of the copper sample is mathematically given as
Q=8.86809J
<h3> Heat flow</h3>
Question Parameters
- A temperature of a 0.349 kg sample of copper
- decreases from 87.0 °C to 21.0 °C.
Endothermic Reaction
It is common knowledge that an endothermic reaction is one where the system absorbs heat energy from the <em>environs</em>.
Exothermic Reaction
An exothermic reaction is one where the system releases heat energy to the <em>environs</em>.
Generally the equation for Heat is mathematically given as
Q=8.86809J

Answer:
I = 33.04A
Explanation:
The magnetic field at the center of a loop of wire is proportional to the current flowing through the wire and inversely proportional to the radius
So therefore we have:
20/23 = I/38.0
We then solve for I
cross multiplying we have 20 x 38 = 23 x I
I = 20 x 38/ 23
I = 33.04A
