The specific heat of a certain type of cooking oil is 1.75J/g°C. How much heat energy is needed to raise the temperature of 2.63kg of this oil from g

Complete question:

The specific heat of a certain type of cooking oil is 1.75J/g°C. How much heat energy is needed to raise the temperature of 2.63 kg of this oil from 23 °C to 191 °C?

The heat energy required to raise the temperature of this cooking oil is 773220 J

Explanation:

Given;

mass of the cooking oil, m = 2.63 kg = 2630 g

specific heat capacity of the cooking oil, C = 1.75J/g°C

initial temperature of the cooking oil, T₁ = 23° C

final temperature of the cooking oil, T₂ = 191° C

The heat energy required to raise the temperature of this cooking oil;

Q = mcΔT

Q = 2630 x 1.75 x (191 - 23)

Q = 773220 J

Therefore, the heat energy required to raise the temperature of this cooking oil is 773220 J

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.
