1 horsepower is equal to 746 W, so the power of the engine is
The power is also defined as the energy E per unit of time t:
Where the energy corresponds to the work done by the engine, which is
. Re-arranging the formula, we can calculate the time t needed to do this amount of work:
Answer:
Is this for zoommmmmmmmmm?
Explanation:
It had to be 20 letters I had to do something
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
Explanation:
Answer:
True
Explanation:
As we know that total charge is always quantized and in the terms of multiples of charge of single electron
so we have
Q = Ne
here we know that
also we know that
so we have
Since this charge is in multiple of micro coulomb units so yes it is possible to measure it
and the magnitude of this charge is given as
Answer:
Option (a) is correct.
Explanation:
For us to be able to visualize an object, there are basic processes that takes place in a split second.
First Light which strike the object reflect into our eye. This reflected light passes through the pupil as the iris gives way for it. This light moves through other layers and impinges on the retina and stimulates it. This is the process of within the eye processing. The light is then converted to a signal by the optic nerve and sent to the brain for interpretation. The image produced by the retina is inverted. The brain helps to interpret this image as upright. This is the reason why we see objects just the way they are
