Answer:
Q = 675 [J]
Explanation:
We can calculate the amount of heat transfer by means of the following expression that includes the mass and temperature change in a body as a function of the specific heat.

where:
m = mass = 25 [gr]
Cp = specific heat = 0.9 [J/g*°C]
Tinitial = 55 [°C]
Tfinal = 25 [°C]
![Q=25*0.9*(55-25)\\Q=675 [J]](https://tex.z-dn.net/?f=Q%3D25%2A0.9%2A%2855-25%29%5C%5CQ%3D675%20%5BJ%5D)
Answer:
The allowed current in the cable is 1.15 A.
Explanation:
Given that,
Distance = 1.00 m
Suppose the magnetic field is
and if the experiment is to be accurate to 1.0 %
We need to calculate the current
Using formula of magnetic field


Put the value into the formula


If the experiment is to be accurate to 1.0%
Then,
We need to calculate the allowed current in the cable



Hence, The allowed current in the cable is 1.15 A.
a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.
No ice is either 32 degrees Fahrenheit or 0 degrees Celsius but that's only normal ice, dry ice is a different story but I'm assuming you're talking about normal ice
