Jayden was given a marshmallow and a syringe in class to experiment with. She placed the marshmallow in the syringe and sealed t

he end. When she depressed the plunger of the syringe what happened to the marshmallow and why? A) The increased pressure, pushed the molecules closer together, and caused the marshmallow to shrink. B) The decreased pressure, pushed the molecules closer together, and caused the marshmallow to shrink. C) The increased pressure, allowed the molecules to spread apart, and caused the marshmallow to grow larger.

0.85 x 45 x 128 = 4896

Change in energy = specific heat capacity x mass x change in temperature

Birdman is flying horizontally at a
zavuch27 [327]

Answer:

X=92.49 m

Explanation:

Given that

u= 21 m/s

h= 97 m

Time taken to cover vertical distance h

h= 1/2 g t²

By putting the values

97 = 1/2 x 10 x  t²          ( g = 10 m/s²)

t= 4.4 s

The horizontal distance

X= u .t

X= 21 x 4.4

X=92.49 m

If two opposite charges get farther apart, does their attraction for each other increase, decrease, or remain the same?​
wlad13 [49]

The force between them <em>decreases</em><em>,</em> as the square of the distance.

For example ...

-- If you move them apart to double the original distance, the force becomes (1/2²) = 1/4 of the original force.

-- If you move them apart to 3 times the original distance, the force becomes (1/3²) = 1/9 of the original force.

-- If you move them apart to 5 times the original distance, the force becomes  (1/5²) = 1/25 of the original force.

(Gravity works exactly the same way.)

FromTheMoon [43]

Answer:

  I = 1.875 A

Explanation:

For this exercise we use Ampere's law

             ∫ B . ds = μ₀  I

We use a circular path around the wire whereby B and ds are parallel, whereby the dot product is reduced to the algebraic product

               ds = 2π dr

               B (2πr) = μ₀  I

              I = B 2π R /μ₀  

              r= 7.5 cm = 0.075 m

calculate

             I = (50 μ₀ /π) 2π 0.075 /μ₀  

             I = 1.875 A
