Answer:

933.804423995 m/s²

Explanation:

q_1 = Charge on particle 1 = 67 µC

q_2 = Charge on particle 2 = -25 µC

r = Distance between the particles = 47 cm

k = Coulomb constant = 8.99\times 10^{9}\ Nm^2/C^2

m = Mass of particle = 73 g

Electric force is given by

F=\dfrac{kq_1q_2}{r^2}\\\Rightarrow F=\dfrac{8.99\times 10^{9}\times -25\times 10^{-6}\times 67\times 10^{-6}}{0.47^2}\\\Rightarrow F=-68.1677229516\ N

The magnitude of force is 68.1677229516 N

Acceleration is given by

a=\dfrac{F}{m}\\\Rightarrow a=\dfrac{68.1677229516}{0.073}\\\Rightarrow a=933.804423995\ m/s^2

The acceleration is 933.804423995 m/s²

How does adding more of a substance affect it's density?
fomenos
I’m going to use molasses as an example of a substance.

The mass and volume both change when changing the amount of molasses.
However, the density does not change. This is because the mass and volume increase at the same rate/proportion!

Even though there is more molasses (mass) in test tube A, the molasses also takes up more space (volume). Therefore, the spacing between those tiny particles that make up the molasses is constant (does not change).

The size or amount of a material/substance does not affect its density.

The blank the value of coefficient of friction the greater the resistance to sliding
expeople1 [14]

Answer:

The <u>HIGHER</u> value of coefficient of friction the greater the resistance to sliding

Explanation:

As we know that friction force is given by

F_f = \mu F_n

so friction force is the product of friction coefficient and normal force.

So here we can say that if friction coefficient is higher then the friction force will be more as it is product of friction coefficient and normal force.

So correct answer will be given as

The <u>HIGHER</u> value of coefficient of friction the greater the resistance to sliding
