Answer:

Sample Answer: The lightbulb will not light because this is a short circuit. The branch without the bulb has almost no resistance, so all the current will flow through that branch instead of flowing through the bulb.

Answer:

It will.

Explanation:

For a circuit to function properly, everything has to be connected. As the diagram shows that everything is connected and there are no gaps, it will light.

An object is dropped from a height of 50 meters. Ignoring air resistance, how long doe take to hit the ground?

Arte-miy333 [17]

here given that object is dropped from height h = 50 m

So here we can say

initial speed is ZERO

acceleration is due to gravity

now in order to find time to reach the ground we can use kinematics

$y = v_i*t + \frac{1}{2}at^2$

now plug in all values in it

$50 = 0 + \frac{1}{2} \times 9.8(t^2)$

$t = 3.2 s$

so it will take 3.2 s to reach the ground

The electric field in a region of space increases from 0 to 2150 N/C in 5.00 s. What is the magnitude of the induced magnetic fi

Feliz [49]

To solve this problem we will use the Ampere-Maxwell law, which describes the magnetic fields that result from a transmitter wire or loop in electromagnetic surveys. According to Ampere-Maxwell law:

$\oint \vec{B}\vec{dl} = \mu_0 \epsilon_0 \frac{d\Phi_E}{dt}$

Where,

B= Magnetic Field

l = length

$\mu_0$ = Vacuum permeability

$\epsilon_0$ = Vacuum permittivity

Since the change in length (dl) by which the magnetic field moves is equivalent to the perimeter of the circumference and that the electric flow is the rate of change of the electric field by the area, we have to

$B(2\pi r) = \mu_0 \epsilon_0 \frac{d(EA)}{dt}$
