A bowling ball has a mass of 10.0kg. If a net force of 35N is applied to the ball, what’s the acceleration?
Paraphin [41]

Answer:

Acceleration =  3.5 m.s⁻²

Explanation:

Definition:

The acceleration is rate of change of velocity of an object with respect to time.

Formula:

a = Δv/Δt

a = acceleration

Δv = change in velocity

Δt = change in time

Units:

The unit of acceleration is m.s⁻².

Acceleration can also be determine through following formula,

F = m × a

a = F/m

Given data:

Force = 35 N  (N = Kg. m.s⁻²)

Mass = 10.0 Kg

a = ?

Formula:

a = F/m

a = 35 Kg. m.s⁻²/ 10.0 Kg

a =  3.5 m.s⁻²

Number of moles = 8.3 x 10⁻¹³

<h3>Further explanation </h3>

The mole is the number of particles(molecules, atoms, ions) contained in a substance

1 mol = 6.02.10²³  particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's =  6.02.10²³

5 x 10¹¹ atoms of Silver :

\tt mol=\dfrac{5\times 10^{11}}{6.02\times 10^{23}}=8.3\times 10^{-13}
