The specific heat capacity of silver is 0.06 cal/g°c. how much energy is needed to flow into a 5-gram sample to change its temperature from 10°c to 11°c?

Answer : Energy needed, Q = 0.3 cal

Explanation :

Given that,

The specific heat capacity of silver, c = 0.06 cal/g °C

Mass of the sample, m = 5 grams

It changes its temperature from 10°C to 11°C,

Energy need to flow is given by :

So, the energy needed to flow into this sample is 0.3 cal

Hence, this is the required solution.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
