What is the relationship between the line current i l and the phase current i1 in a balanced delta system?

1 answer:

6 0

<span>In a star connection the line current is equal to the phase current . While in Delta connection the line current is divided by under root 3 to get the phase current.</span>

What does the force of gravity between two objects depend on?

lawyer [7]

-- The equal, mutual forces of gravity between two objects depend on the product
of the two masses ... it doesn't matter whether the masses are equal or there's
one huge mass and one minuscule mass. It's the product that counts.

-- The force also depends on the distance between the centers of the two objects.

A light bulb has a voltage of 36 and a current of 8 A. Calculate the resistance of the light bulb

timurjin [86]

R = U : I. U is in Voltage and I is in Ampère. That gives you R = 36 : 8 = 4,5 Ohm

A woman does 200 j of work on a shopping cart as she pushes it down an aisle that is 20 m long. What was magnitude of the force

Ann [662]

Answer:

10N

Explanation:

Given data

Work done = 200J

distance= 20m

We want to find the applied force

From

Work done= Force * distance

substitute

200= F*20

F= 200/20

F= 10N

Hence the force applied is 10N

How far will a stone travel over level ground if it is thrown upward at an angle of 30.0° with respect to the horizontal and wit

Elis [28]

Explanation:

It is given that, a stone travel over level ground if it is thrown upward at an angle of 30.0° with respect to the horizontal.

Speed with which it is thrown, v = 11 m/s

We need to find the maximum height above the ground level. The maximum height attained by the stone is given by :

$h=\dfrac{v^2sin^2\theta}{2g}$

$h=\dfrac{(11\ m/s)^2sin^2(30)}{2\times 9.8\ m/s^2}$

h = 1.54 m

So, the stone will travel a distance of 1.54 meters.

Range of a projectile is given by :

$R=\dfrac{v^2sin\ 2\theta}{g}$

$R=\dfrac{(11\ m/s)^2sin(60)}{9.8\ m/s^2}$

R = 10.69 m

So, the maximum range achieved with the same initial speed is 10.69 meters. Hence, this is the required solution.
