Answer:

a_x = 0

Explanation:

When projectile is in air then the force on the projectile is only due to its weight

It is vertically downwards

F_g = mg(-\hat j)

so here since we don't have any air drag or friction due to air so there will be no force along its tangent or along x direction

so the acceleration along x direction will be zero

a_x = 0

a_y = - g

Without air resistance, there is no horizontal force on the projectile,
so it has no horizontal acceleration.  The answer is "zero".

grandymaker [24]
<span>Pressure = force / area</span>

I assume that 350kg is the mass 
Therefore, 

350 x 9.8 (gravity) = 3430N

3430 / 1 = 3430Pa

3.43 KPa

Yanka [14]

Answer:

Either heat added or mechanical work done.

Explanation:

Since he found stirring rod on the desk and a cigarette lighter. This means that the beaker was probably either heated with the aid of fire from the lighter.

Also, the stirring rod could have been used to stir the water which will increase the kinetic energy which also means an increase in temperature.

Thus, it's either heat was added or mechanical work was done as a result of stirring.

Answer:It turns out the Venus flytrap is a power plant, capable of generating electrical signals. Each trap is actually a modified leaf: a hinged midrib, which would be the central vein of a more familiar leaf, joins the two lobes, which secrete a sweet sap to attract insects.

Explanation:The leaves of Venus' Flytrap open wide and on them are short, stiff hairs called trigger or sensitive hairs. When anything touches these hairs enough to bend them, the two lobes of the leaves snap shut trapping whatever is inside.
