Katen [24]

Moles Pbl2 = 0.8628 g : 461.01 g/mol = 0.001871

moles I = 2 x 0.001871 = 0.003742

[I-] = 0.003742/ 0.0429

= 0.0872 M

How much force is required to move a sled 5 meters if a person uses 60 J of work?

Brut [27]

W=F*S

W - Work
F - Force
S - Distance (from latin word 'spatium)

so...
S= 5 (m)
W=60 (J)

W=F*S
F=W/S
F=60/5=12 J/m = 12 N (Newtons)

A 4.0-kg mass is moving with speed 2.0 m/s. A 1.0-kg mass is moving with speed 4.0 m/s. Both objects encounter the same constant

Kazeer [188]

Answer

given,

mass of object 1 = 4 Kg

Speed of object 1 = 2 m/s

mass of object 2 = 1 Kg

speed of object 2 = 4 m/s

KE of the object 1 = $\dfrac{1}{2}MV^2$

= $\dfrac{1}{2}\times 4 \times 2^2$

= 8 J

KE of the object 2 = $\dfrac{1}{2}MV^2$

= $\dfrac{1}{2}\times 1 \times 4^2$

= 8 J

Kinetic energy of both the object is same hence,Work done by both the object will also be same.

It is given that braking force is same in both cases.

So, distance travel by Both the object will be same.
