Answer:
As Per Given Information
Mass of Car 4000 Kg
Acceleration of car 20m/s²
we have to find the force required to make the car car accelerate at given magnitude .
Using Formulae
- Force = Mass × Acceleration
On Putting the value we obtain
↝ Force = 4000 × 20
↝ Force = 80000 N
↝ Force = 80KN
So, the force required to maintain the given acceleration is 80 KiloNewton .
Charles law gives the relationship between temperature and volume of gases. It states that the volume of gas is directly proportional to temperature at constant pressure.
V / T = k
where V - volume and T - temperature in Kelvin and k - constant

where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 - 20 °C + 273 = 293 K
substituting these values in the equation

T = 586 K
temperature in celsius = 586 K - 273 = 313 °C
new temperature is 313 °C
The correct answer is B. balance
Answer:
maybe number b is correct. ...thank you
