An inductor is connected in series to a fully charged capacitor. which of the following statements are true?

1 answer:

4 0

The true statements would be ; the stored field energy can be greater than the stored magnetic field energy, the stored electric field energy can be equal to the stored magnetic field energy, As the capacitor is discharging, the current is increasing and the stored electric field energy can be less than the stored magnetic field energy. A capacitor in a series circuit with a resistor charges by passing charges through the resistor. As charging proceeds, the p.d across the capacitor increases until it reaches the value of the supply voltage. When a capacitor is charged it stores energy, which it can supply to other components when it discharges.

the Earth exerts a gravitational force of 500 newtons on an object what is the mass of the object in kilograms

MAXImum [283]

Use Newton's second law F = mass * acceleration
In your problem F = 500, and we know gravity is working on it so use a = 9.81
Substitute into the equation
500 = m * 9.81
m = 50.97 kg

In a city grid, each block on the east-west streets is 100 meters long. Each block on the north-south streets is 20 meters long.

alex41 [277]

Answer:

72.1 m

Explanation:

Hello!

When the walker walks west, each block he walks will be of 100 m, so the walker walked 4*100m = 400 m west.

Similarly, when the walker walks south, he walks 20 meters per block, therefore, the walker walked 4*20 m = 80 m south.

Since the directions west and south are perpendicular, the distance between the start ad end point is:

d = √(400^2 + 80^2) m = 407.92 m

However the walker traveled 480 m

Therefore, the walker traveled 480 - 407.9 m = 72.1 m farther than the actual distance

Which of the following graph is used for determining the instantaneous velocity from the slope?

hoa [83]

Answer:

B. x - t graph

Explanation:

A position-time (x-t) graph is a graph of the position of an object against (versus) time.

Generally, the slope of the line of a position-time (x-t) graph is typically used to determine or calculate the velocity of an object.

An instantaneous velocity can be defined as the rate of change in position of an object in motion for a short-specified interval of time. Thus, an instantaneous velocity is a quantity that can be found by measuring the slope of a line that is tangent to a point on the graph.

Hence, the x - t graph also referred to as the position-time graph is used for determining the instantaneous velocity from the slope.

<u>For example;</u>

Given that the equation of motion is S(t) = 4t² + 2t + 10. Find the instantaneous velocity at t = 5 seconds.

Solution.

$S(t) = 4t^{2} + 2t + 10$
