A parallel plate capacitor has a capacitance of 6.78 μF and it is connected to a 12V battery. What is the charge on the capacitor?
Answer:
8.136×10⁻⁵ J
Explanation:
Applying,
Q = Cv................ Equation 1
Where Q = Charge on the capacitor, v = voltage of the battery, C = capacitance of the capacitor.
From the question,
Given: C = 6.78μF = 6.78×10⁻⁶ F, v = 12 V
Substitute these values into equation 1
Q = (6.78×10⁻⁶ )(12)
Q = 8.136×10⁻⁵ J
Hence the charge on the capacitor is 8.136×10⁻⁵ J
3 - An object is being pushed with a net force of 15 N. If the net force is cut in third to 5 N, how will the acceleration be changed?
Answer:
Explanation:
F = ma is a linear equation. This means that the Force change as the accleration changes. And vice versa. If the Force is cut in thirds, then the acceleration is also cut in thirds. Let's do some math on this just to prove it, shall we?
We know that at first, the F = 15. Let's give this object a mass of 5kg. That means that
15 = 5a so
a = 3
Then the F is cut into thirds, so
5 = 5a so
a = 1
The second acceleration is one-third of the first one, where the Force is 3 times greater.

Answer:
Direction: north-west (45 degrees)
Magnitude: 500 N
Explanation:
The wind exerts a force upwards, a.k.a. north.
The water exerts a force to the left, or west.
The directions are 90 degrees apart from each other, so the angle of the je force is 45 degrees (north-west).
We can use the Pythagorean theorem to calculate the magnitude.

Answer:
B. 175 N
Explanation:
Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.
Mathematically, net force is given by the formula;
[tex] Fnet = Fapp + Fg[/tex]
Where;
Fnet is the net force
Fapp is the applied force
Fg is the force due to gravitation
In this scenario, we observed that both forces are acting in the same direction.
Therefore:
Net force = 100 N + 75 N
Net force = 175 Newton

Write a complete scientific explanation to account for why the ball that was moving faster caused more flour to spread out.
Answer:
It is due to the large impulse is imparted on the flour.
Explanation:
A ball is moving faster.
When a ball is moving faster strikes to the flour, the change in momentum is large and thus the impulse imparted on the flour is large.
Impulse = change in momentum
So, as the flour experiences large impulse and large momentum so that the flour spreads out.
If the change in momentum is large so the flour spreads out is more.
When a ball moves with faster velocity, then a greater impulse force is generated that causes more flour to spread out.
What is momentum?Momentum can be defined as the mass in motion. It is the product of mass and velocity. It is given by the formula,
p = mv
where p is the momentum, m is the mass, and v is the velocity.
As we know that the ball has some mass and the ball is moving with some velocity, therefore, the ball will have some momentum. Also, we know that when the ball will hit the flour the momentum of the ball will become zero, therefore, the change in momentum in such a short time will generate an impulse.
Thus, if the velocity of the ball is more than the impulse generated will be more which will cause more flour to spread out.
Hence, When a ball moves with faster velocity, then a greater impulse force is generated that causes more flour to spread out.

Answer: hello the options related to your question is missing attached below are the missing options
answer : The molecules with the highest temperature will bounce off their neighbors, losing energy to them and so on until the system is at a new equilibrium with the piston moved out ( option B )
Explanation:
What best describes the situation of what will happen next as explained in the question is in Option B
Because molecules with higher temperatures will always posses higher kinetic energy and they will collide more frequently with surrounding molecules passing on their energy in the process until the energy gets to the molecules closest to the piston. The molecules closest to the piston will then hit the piston until a new equilibrium is achieved
