The average net force exerted is 36000 N.
<u>Explanation</u>:
According to Newton's 2nd law of motion,
The net force acting upon the object is the product of mass and acceleration of an object.
Force = ma
where m represents the mass,
a represents the acceleration.
Acceleration = (change in speed) / (change in time)
Acceleration = (45 m/s) / (7 sec) = (45 / 7) m/s²
Force = (5,600 kg) x (45 /7 m/s²)
Force = (800 x 45) Newtons
Force = 36000 Newtons.

C. 0.37V. A capacitor of 650x10⁻⁴F that stores 24x10⁻³C has a potential difference of 0.37V between its plates.
The key to solve this problem is using the capacitance equation C = Q/Vᵃᵇ, where C is the capacitance, Q the charge stored in the plates, and Vᵃᵇ the potential difference between the plates.
A 650x10⁻⁴F capacitor stores 24x10⁻³C, clear Vᵃᵇ for the equation:
C = Q/Vᵃᵇ -----------> Vᵃᵇ = Q/C
Solving
Vᵃᵇ = 24x10⁻³C/650x10⁻⁴F = 0.37V
I think your answer is D
because you already said its not a B is a liquid and not a solid so its harder to have a chemical change C is solutions and D is compound and I know for a fact that a compound is a solid and if C is also a solid then that could also be a possible answer choice.
Answer:
The acceleration is 30 m/s²
Explanation:
Given that,
Maximum speed = 120 m/s
Time = 4.0 sec
We need to calculate the acceleration
Using equation of motion
Where, v = speed
u = initial speed
a = acceleration
t = time
Put the value into the formula
Hence, The acceleration is 30 m/s²
