Weight of the automobile</h3>
The weight of the automobile is calculated as follows;
P = F / A
F = (W/4)
P = (W/4) / A
P = W/4A
W = 4AP
where;
W = (4)(217 x 10⁻⁴ m²)(2.02 x 10⁵ Pa)
W = 17,533.6 N
Thus, the weight of the automobile is 17,533.6 N.

Hello.
The answer: D. The conservation of momentum
The conservation of momentum is for a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.
Have a nice day
Answer:
Position of x at t = 1.44s is - 0.0817 m
Explanation:
For the harmonic motion of the spring, the displacement is given by
x = A cos wt
A is the amplitude of displacement = 0.14 m
t = time = 1.44 s
w = angular frequency and for a spring's motion, it is given by
w = √(k/m)
k = spring's stiffness = 6.5 N/m
m = 2.8 kg
w = √(6.5/2.8) = 1.524 rad/s
x = 0.14 cos (1.524 × 1.44) = 0.14 cos 2.194 = 0.14 × - 0.5836 = - 0.0817 m
The correct answer is oxygen since they have different charges
I hope this helped and good luck
thank you
