Answer:

Its physical change

Explanation:

because if you break the glass you can put it back together, chemical change says you cant be converted back to its original form( for example burn wood once wood burns it turns to ashes)

I think it’s physical change, because the objects aren’t changing into another substance, just changing their physical shape. Hope this helps!

Red laser light passes through a single slit to form a diffraction pattern. If the width of the slit is increased by a factor of
SCORPION-xisa [38]

If the width of the slit is increased by a factor of two , then the central maxima will get decreased by half.

since , width of the central maxima is inversely proportional to the width of the slit . Which implies if width of the slit get increased then width of the central maxima will get decreased and vice versa.

central maxima = (2 * wavelength * D) / width of the slit

                          = (2 * lambda * D) / d

if initially width of the slit = d

then, after increasing it by a factor of two it become =  2d

central maxima  =  (2 * lambda * D) / 2d

                           = (lambda * D) / d

If the width of the slit is increased by a factor of two , then the central maxima will get decreased by half.

How is work affected when an object is lifted straight up instead of using a ramp? Work will increase.
kifflom [539]
Without friction, the amount of work only depends on the final height,
and is not affected by the route used to get there. 

If the ramp has no friction, then it has no effect on the total amount
of work done.  The work to lift the load straight up is the same.

If the ramp has some friction, then it takes more work to use the ramp
than to lift the load straight up.  Then the work to lift the load straight up
would be less than when the ramp is used.

What's the difference between speed and velocity
Natasha_Volkova [10]

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
