Sound travels faster in cold air bro
Answer:
Torque; τ = 4.712 × 10^(-3) J
Magnetic moment; M = 0.0248 J/T
Explanation:
Torque is gotten from the formula;
τ = BIA
Where;
B is magnetic field
I is current
A is area
We are given;
B = 0.19T
I = 6.2A
Rectangle dimensions = 5cm by 8cm = 0.05m by 0.08m
Thus;
Area; A = 0.05m × 0.08m = 0.004 m²
Thus;
τ = 0.19 × 6.2 × 0.004
τ = 4.712 × 10^(-3) J
Formula for the magnetic moment is given by;
M = IA
M = 6.2 × 0.004
M = 0.0248 J/T
Answer:
The final temperature is 85.86°C.
Explanation:
Given that,
Mass of tea = 200 g
Mass of glass = 150 g
Initial temperature = 25°C
We need to calculate the final temperature
When equilibrium is reached, assuming no heat flows to the surroundings
So,
We know that,
Specific heat of tea = 1.00 cal/gm° C
Specific heat of tea = 0.20 cal/gm° C
Put the value into the formula
Put the value of initial temperature
Hence, The final temperature is 85.86°C.
