Answer:

Coefficient

Explanation:

For an object on level ground, the ratio of the friction force to the weight is the coefficient of friction.

F / W = μ

What is the mass of a 100-N crate of delicious candy
Svetach [21]

Answer:

Explanation:

weight ( w ) = 100 N

mass (m) = ?

WE know

g = 10 m/s²

w = m * g

or

m = w / g

m = 100 / 10

m = 10 kg

hope it will help :)

Experiments using "optical tweezers" measure the elasticity of individual DNA molecules. For small enough changes in length, the
GalinKa [24]

Answer:

Spring constant, k = 0.3 N/m

Explanation:

It is given that,

Force acting on DNA molecule, F=1.5\ nN=1.5\times 10^{-9}\ N

The molecule got stretched by 5 nm, x=5\times 10^{-9}\ m

Let k is the spring constant of that DNA molecule. It can be calculated using the Hooke's law. It says that the force acting on the spring is directly proportional to the distance as :

F=-kx

k=\dfrac{F}{x}

k=\dfrac{1.5\times 10^{-9}\ N}{5\times 10^{-9}\ m}

k = 0.3 N/m

So, the spring constant of the DNA molecule is 0.3 N/m. Hence, this is the required solution.
