Answer:
Complete Circuit
Explanation:
A circuit is defined as a completed path for voltage to flow from a source of voltage through a load and back to the source. A complete circuit or path is often referred to as a(n) ? circuit. Before current can flow in a circuit, the circuit must be closed. 100% right
Explanation:
EE = ½ kx²
EE = ½ (0.55 N/m) (0.15 m)²
EE = 0.62 J
Force = mass * acceleration. Therefore, given the force of 120 N and the mass of 46 kg:
120 N = 46 kg * acceleration
120 kg-m/s^2 = 46 kg * acceleration (in m/s^2)
acceleration = 120/46 = 2.61 m/s^2
Answer:
C) Acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
Explanation:
- Velocity is a vector quantity, which consists of a magnitude (the speed) and a direction. In the case of the circular motion, as in this problem, the speed is constant (45 m/h), but the direction is constantly changing, so the velocity is changing as well.
- Acceleration is also a vector quantity, whose magnitude is equal to the rate of change of the velocity, and the direction is given by the change in direction of the velocity. Therefore, since the velocity is changing, the acceleration in this problem is changing as well.
because as the distance increases the gravitational force decreases so the weight of a body decreases
