Find the magnitude of the vector 33 i^+ 15 j^m.

Physics
1 answer:
Olenka [21]3 years ago
7 0
The magnitude of  33 i  +  15 j  is

                   √ (33² + 15²)

               =  √ (1089  +  225)

               =   √ 1314   =   36.25   (rounded)

If a current of 0.5 A flows in a 75 W light bulb when the voltage difference between the ends of the filament is 150 V, what is
serious [3.7K]
Power is current times voltage.  Using Ohm's Law V=IR, we can express power in two additional ways:
P=I^2R \\ P= \frac{V^2}{R}
So for P=75W, we can use either of these to get R.  Let's use the first one:
75W=(0.5A)^2R \\  \frac{75W}{0.25A^2}=300 \Omega

Close a door by pushing on the doorknob. Close the door again using approximately the same force but applying it 5 centimeters a
AURORKA [14]

Answer:

Check below for the explanation

Explanation:

a) Torque, \tau = rfsin \theta

The larger the distance , r, the smaller the force needed to push the door, but the higher the torque.

The torque was larger when the force was applied 5 cm away than when it was applied at the knob because the distance becomes larger. The higher the distance, r, the larger the torque produced.

When the force was applied on the edge of the door in a direction pointing towards the hinge, the torque, τ became zero because the force was applied in the same direction to the the distance, r. i.e the angle, θ = 0.

b)Force is applied in a straight line, and the body accelerates in the direction of the force. The unit of force is Newton

Torque is the force applied at a distance from the center of rotation. It's unit is newton meters.

Torque is the time rate of change of angular momentum while force is the time rate of change of linear momentum

When electrical is "used by a light bulb", what really happens to energy
Paha777 [63]
It gets converted from one form to other forms.

The great thing about the incandescent light bulb ... the original kind,
invented by Thomas Edison ... is that it can take electrical energy and
instantly turn it into light energy and heat energy.  So you can use the
bulbs in your house to see at night without burning candles or oil, and
you can even use them in your chicken coop to keep the chickens warm.  

I used one a few years ago when I found a tiny abandoned baby possum under the bush in my front yard.  The poor thing was almost frozen.  I put
it in a box with a few of my old T-shirts, and put an incandescent light bulb
under the box to keep it warm.  In the morning, I took it to a wildlife rescue place on the lake-shore here in Chicago.  They told me that the baby would
not have survived without the heat overnight.  And three months later, they
sent me an email saying that my baby possum had grown big and strong,
and that they took him to the forest preserve and released him in the wild.

That was a rare occasion.  We don't actually use light bulbs for heat too
much any more, so it's considered wasted energy in light bulbs. We have
better ways to generate heat now, and for light, we're changing to devices
that run cool and make a lot more light with the same amount of electrical
energy ... like fluorescent tubes, CFL curly bulbs, and LED bulbs.  The
incandescent bulb is going away. 

But the principal is still the same ... convert electrical energy into light energy.
