A 10.0-kg box starts at rest on a level floor. An external, horizontal force of 2.00 × 102 N is applied to the box for a distanc
Harman [31]

Answer:

vf = 11.2 m/s

Explanation:

m = 10 Kg

F = 2*10² N

x = 4.00 m

μ = 0.44

vi = 0 m/s

vf = ?

We can apply Newton's 2nd Law

∑ Fx = m*a   (→)

F - Ffriction = m*a  ⇒  F - (μ*N) = F - (μ*m*g) = m*a   ⇒  a = (F - μ*m*g)/m

⇒    a = (2*10² N - 0.44*10 Kg*9.81 m/s²)/10 Kg = 15.6836 m/s²

then , we use the equation

vf² = vi² + 2*a*x    ⇒    vf = √(vi² + 2*a*x)

⇒   vf = √((0)² + 2*(15.6836 m/s²)*(4.00m)) = 11.2 m/s

If the time for 20 vibrations is 100 second then find
Lilit [14]

hey guy

the vibration per second is frequency

then for 20 vibration time taken is 100 second

in 1 second 20/100 vibration took place

it means 0.2 is frequency

for time period , we have

t=1/f

=1/0.2

=5

<span>A molded bread is a good example of a chemical change. A chemical change is a kind of change in which a new substance is formed. In a chemical change, the original substance which started the reaction can not be recovered.The molded bread formed in this given instance is a new substance which is different from the original bread, so also, the original bread can no longer be retrieved from the molded bread.</span>
