Answer:

$T_2=12\°C$

Explanation:

Hello there!

In this case, according to the Charles' law equation which help us to understand the directly proportional relationship between volume and temperature:

$\frac{T_2}{V_2}=\frac{T_1}{V_1}$

Thus, by solving for the final temperature, T2, and making sure we use the temperatures in Kelvin, we can calculate the final temperature as shown below:

$T_2=\frac{T_1V_2}{V_1} \\\\T_2=\frac{(27+273)K*19L}{20.0L}\\\\T_2=285-273\\\\T_2=12\°C$

Best regards!

What are the magnitude (size) and direction of the cumulative force acting on the car shown in the picture A. 30 N to the right

UNO [17]

Answer: The correct answer is option(A).

Explanation:

Total forces exerting on the car = F

$F_r=50 N$ = Force on car exerting in right direction

$F_l=20 N$ = Force on car exerting in left direction

$F_u=2500 N$ = Force on car exerting in upward direction

$F_d=2500 N$ = Force on car exerting in downward direction

$F=F_r+F_l+F_u+F_d$

$(-F_u)=F_d$ (negative sign shows the direction)

Since, upward force are equal in magnitude but opposite in direction by which they will balance out each other.so, the net force car will be due to two forces $F_r$ and $F_l$

$F=F_r+F_l=50 N+(-20 N)=30 N$ (negative shows the direction)

The magnitude (size) and direction of the cumulative force acting on the car will 30 N towards right direction.Hence, correct answer is option(A).
