Answer:

The current in an oscillating LC circuit is zero when the charge on the capacitor is equal to zero coulombs.

Explanation:

Because when the charge would not flow through the circuit then current in an oscillating circuit will be zero.

Calculate the pressure of water at the bottom of 6m depth well.( g= 9.8m/s square<br>

Alexeev081 [22]

Answer:

58.8NM-²

Explanation:

The pressure is the product of density,depth(height) and acceleration due to gravity

here the density of water is 1gm-³ it a constant so it not given

pressure= 6×9.8×1

pressure = 58.8NM-²

2 ways to change frictional force between 2 objects

Zanzabum

In order to change the frictional force between two solid surfaces, it can be changed by shorter distances and by the amount of weight it has or the amount of force that is pushing that object to go however distance it can.

If a car takes a banked curve at less than a given speed, friction is needed to keep it from sliding toward the inside of the cu

zubka84 [21]

Answer:

minimum speed is 15.35 m/s

frictional coefficient is 0.26

Explanation:

given data

radius = 84 m

angle = 16°

speed = 16 km/h = 4.43 m/s

to find out

minimum speed and minimum coefficient

solution

we will apply here formula for velocity that is

velocity² = radius × g × tanθ

v² = 84 × 9.8 × tan16

v² = 236.04

v = 15.35 m/s

and

we find first friction force here

friction force 1 = m v² /r

friction force 1 = m (15.35)² / 84 = 2.80 m

and

friction force 2 = m v² /r

friction force 2 = m (4.43)² / 84 = 0.245 m

so total friction force = f1 - f2

total friction force = 2.80 - 0.245 = 2.55 m

so frictional coefficient = friction force /g

frictional coefficient = 2.55 / 9.8

so frictional coefficient is 0.26
