Answer:
Q= -6900 J
Explanation:
use the formula Q=mC(T_2 - T_1) and sub in givens
Q=mC(T_2 - T_1)
Q= (200 g)(0.444 J/g°C)(22-100)
Q= -6900 J
The negative sign means heat is lost, which agrees with the decrease in temperature
Underhand serve is a type of volleyball serve in which a player holds the ball with one hand and swings the other hand in an arc motion, striking under the ball with a fist to put it into play. An underhand serve is the most common serve for beginners.
Answer:
Social psychologists utilize experimental techniques to study how people are influenced by groups. Health psychologists rely on experimentation and research to better understand the factors that contribute to wellness and disease.

Answer:
Mutual inductance, ![M=2.28\times 10^{-5}\ H](https://tex.z-dn.net/?f=M%3D2.28%5Ctimes%2010%5E%7B-5%7D%5C%20H)
Explanation:
(a) A toroidal solenoid with mean radius r and cross-sectional area A is wound uniformly with N₁ turns. A second thyroidal solenoid with N₂ turns is wound uniformly on top of the first, so that the two solenoids have the same cross-sectional area and mean radius.
Mutual inductance is given by :
![M=\dfrac{\mu_oN_1N_2A}{2\pi r}](https://tex.z-dn.net/?f=M%3D%5Cdfrac%7B%5Cmu_oN_1N_2A%7D%7B2%5Cpi%20r%7D)
(b) It is given that,
![N_1=550](https://tex.z-dn.net/?f=N_1%3D550)
![N_2=290](https://tex.z-dn.net/?f=N_2%3D290)
Radius, r = 10.6 cm = 0.106 m
Area of toroid, ![A=0.76\ cm^2=7.6\times 10^{-5}\ m^2](https://tex.z-dn.net/?f=A%3D0.76%5C%20cm%5E2%3D7.6%5Ctimes%2010%5E%7B-5%7D%5C%20m%5E2)
Mutual inductance, ![M=\dfrac{4\pi \times 10^{-7}\times 550\times 290\times 7.6\times 10^{-5}}{2\pi \times 0.106}](https://tex.z-dn.net/?f=M%3D%5Cdfrac%7B4%5Cpi%20%5Ctimes%2010%5E%7B-7%7D%5Ctimes%20550%5Ctimes%20290%5Ctimes%207.6%5Ctimes%2010%5E%7B-5%7D%7D%7B2%5Cpi%20%5Ctimes%200.106%7D)
![M=0.0000228\ H](https://tex.z-dn.net/?f=M%3D0.0000228%5C%20H)
or
![M=2.28\times 10^{-5}\ H](https://tex.z-dn.net/?f=M%3D2.28%5Ctimes%2010%5E%7B-5%7D%5C%20H)
So, the value of mutual inductance of the toroidal solenoid is
. Hence, this is the required solution.
Its physical weathering and physical weathering can be sometimes called mechanical weathering it includes the processes which break rocks apart changing their chemical composition.
