5mole

Explanation:

Given parameters:

Mass of element  = 190g

Atomic mass = 38

Unknown:

Number of moles = ?

Solution:

A mole is a unit of measurement for quantifying particles.

 Number of moles = \frac{mass }{molar mass}

 The molar mass is the atomic mass here:

  Number of moles = \frac{190}{38} = 5mole

Which of the following point towards the center of the circle in uniform circular motion?
Luba_88 [7]

Answer: E) Acceleration, net force

Explanation: In order to explain this problem we have to consirer that the uniform circulat motion has constant angular velocity (ω) and the vector velocity is changed its direction for any point that cover the circle but its modulus is contant and its value is v=ω*R.  In order to ensure these conditions, the net force also the accelaration called centripetal must point to the center of the circular trajectory.

Water is poured into a bowl at a constant rate of 17.0 cm^3/s. The bowl has a circular cross section, but does not have a unifor
7nadin3 [17]

Answer:

10.29 cm/s

Explanation:

Discharge in to the bowl = 17.0 cm³/s

Diameter of the bowl, d₁ = 1.45 cm

Now,

Rate at which water level rise at its diameter = \frac{\textup{Discharge}}{\textup{Area of cross-section}}

also,

Area of cross-section = \frac{\pi}{\textup{4}}\times1.45^2

or

Area of cross-section = 1.651 cm²

Therefore,

Rate at which water level rise at its diameter = \frac{\textup{17}}{\textup{1.651}}

or

Rate at which water level rise at its diameter = 10.29 cm/s

If the ball is stationary just before it is hit and goes 5.40 m high, what impulse did she impart to it?
weeeeeb [17]

Energy is conserved. If the ball reaches a height of 5.50 m, it has gained a certain amount of gravitational potential energy. That energy had to come from somewhere. From this fact, you can deduce the speed of the ball at the end of the impact with the racket.

<h3>What is gravitational potential energy?</h3>

Gravitational energy or gravitational potential energy is the potential energy a huge item has corresponding to one more monstrous article because of gravity. It is the potential energy related with the gravitational field, which is delivered (changed over into active energy) when the articles fall towards one another. Gravitational potential energy increments when two articles are brought further apart. It is the potential energy related with the gravitational field, which is delivered (changed over into dynamic energy) when the items fall towards one another. Gravitational potential energy increments when two items are brought further separated.
