Answer:
3.422 m/s^2
Explanation:
A useful relation is ...
v2^2 -v1^2 = 2ad
(25 m/s)^2 -(3 m/s)^2 = 2a(90 m)
(616 m^2/s^2)/(180 m) = a ≈ 3.422 m/s^2
The acceleration is about 3.422 m/s^2.
Net force required to accelerate the car is 6000 N
Explanation:
- Force is calculated by the equation, F = Mass × Acceleration
- This is based on Newton's Second Law of Motion which states that the force acting on an object is its mass times the acceleration of the object.
Here, mass = 3000 kg and acceleration = 2 m/s²
⇒ Force = Mass × Acceleration
= 3000 × 2 = 6000 N
⇒ F = 6000 N
⇒ M = 3000 kg
⇒ a = 2 m/s²
A capacitor is connected to an ac supply. increasing the frequency of the supply increases the current through the capacitor
A capacitor is a device for storing electrical energy that consists of two insulated conductors in close proximity. The parallel-plate capacitor is a simple example of such a storage device.
A capacitor (also known as a condenser) is a two-terminal passive electrical component that stores energy electrostatically in an electric field. Practical capacitors come in a variety of shapes and sizes, but they all have at least two electrical conductors (plates) separated by a dielectric (i.e., insulator).
Capacitors exist in various shapes and sizes, and their value is measured in farads (F). Capacitors are utilized in both alternating current and direct current systems.

Explanation:
<h2>Answer:-</h2>
The Object was at rest. So, Initial Velocity is Zero.
- [Initial Velocity]u = 0
- [Final Velocity]v = 20 m/s
- [Time]t = 2 seconds
- Mass = 4kg
- Force = ?
We know that:-
Applying it, we get:-
