The heat is exchanged when two different temperature objects come in contact. The energy gained by an ice block is 2.3 Joules.
<h3>What is temperature?</h3>
Temperature is the degree of hotness and coldness of the object.
A 7g block of ice was added to a coffee cup full of 103.4 grams of water. The water had an initial temperature T₁ = 24.5 C and a final temperature T₂ = 19.2 C after all the ice had melted.
Heat lost by water = Heat gained by ice
Qgain = ms(T₂ -T₁ )
Substituting the value for mass of water m =103.4 g= 0.1034 kg , specific heat of water s = 4.18 kJ/kg and temperature values, we get
Qgain = 0.1034 x 4.18 x (24.5 - 19.2)
Qgain = 2.3 Joules
Thus, the energy gained by an ice block is 2.3 Joules.

Answer:
78 miles
Explanation:
The average velocity of the bus is given by:
where
d is the displacement (the distance between the two cities)
t is the time taken
In this problem, we have
t = 1.5 h
v = 52 mph
So, we can solve the formula to find d, the distance between the cities:
Answer:
Technician B
Explanation:
This can be explained as a fuse is a protective device which blows in order to protect the circuit and the equipment from short circuiting.
Short circuit is a condition where a very heavy current flow through the line with no low line impedance which is not the intended path for the current to flow.
Thus when heavy current flows through a fuse it blows out thus disconnecting the path for the current flow.
Therefore, if a fuse burns out when switch is on, short circuit is present after the switch
