Answer:

Temporary? You have two options

If you have a positively charged object, bring it close to the LEFT side of the ball (not touching it!).

If you have a negatively charged object, bring it close to the RIGHT side of the ball (again, not in contact).

Either way, the electron cloud will migrate towards the right side of the of your sphere.

Another option is to have a capacitor large enough to house the sphere inside it, and polarize it by attaching it to a DC source making sure that the negative plate of it is to the right of the sphere.

An underwater observation room at an offshore oil rig has a 50-cm diameter window. The center of the window is located at a dept

Murljashka [212]

Answer:

$F = 3.17 \times 10^4 N$

Part b)

Force will act at the center of the window

Explanation:

Pressure at the centre of the window is given as

$P = P_o + \rho gH$

here we know that

$P_o = 1.01 \times 10^5 Pascal$

$\rho = 1.028 \times 10^3 kg/m^3$

g = 9.81 m/s/s

H = 6 m

$P = (1.01\times 10^5) + (1.028\times 10^3)(9.81)(6)$

$P = 1.615\times 10^5 Pa$

now the area of the window is given as

$A = \pi r^2$

$A = \pi(0.25)^2 = 0.196 m^2$

Now force on the window is given as

$F = 0.196(1.615\times 10^5) = 3.17\times 10^4 N$

Part b)

Force will act at the center of the window

SI units is an improved version of MKS system why

nataly862011 [7]

International union of Physics had recommended the MKSA system to serve as the basis, but without forcing the abandonment of CGS by Physicists. The end result was SI approved in 1960. MKS system was based on three base quantities.

Is calculating the change of velocity the same as calculating acceleration?

koban [17]

Answer:

Yes! Thinking about it graphically a position vs time graph models meters per second in most cases, making every point on the line have the units m/s. If we want the find the slope we are finding the change between each point and those units would change to m/s/s or m/s^2 giving us the same units for acceleration. Simply put, slope of a velocity graph gives us acceleration.

When the light bulb is lit, a current is flowing through it. what condition must be met so that a current flows

BlackZzzverrR [31]

Closed loop, conductor medium and presence of current in the wire are the conditions must be met so that a current flows.

<h3>What are the basic conditions for the flow of electric current?</h3>

The loop from where the current passes must be closed. There must be some current in the circuit in order to lit the bulb. The medium through which current flows should be a conductor.

So we can conclude that closed loop, conductor medium and presence of current in the wire are the conditions must be met so that a current flows.

A wooden block has a mass of 12 kg and is experiencing a force of 6 N. Calculate the acceleration that the wooden block will exp

Ierofanga [76]

Use the formula f = m•a and rearrange it to solve for a.

f = m•a
a = f/m
a = 6N / 12 kg
a = 0.5 m/s
therefore the block is experiencing an acceleration of 0.5 m/s.
