Answer: polar covalent bonding

Explanation:

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.

Ionic bond is formed when there is complete transfer of electron from one atom to another atom.

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms.

Water molecules are bonded by strong hydrogen bonding between the hydrogen atom and the electronegative oxygen atom by sharing of electrons and thus form polar covalent bonds.

Answer:

In a polar covalent bond, the electrons are unequally shared by the atoms and spend more time close to one atom than the other.

17. A 25 kg block is initially at rest on a rough, horizontal surface. A horizontal force of 75 N is required to set

lapo4ka [179]

Answer:

0.30581

0.24464

Explanation:

$\mu_s$ = Coefficient of static friction

$\mu_k$ = Coefficient of kinetic friction

$F_f$ = 75 N

$F_k$ = 60 N

Normal force

$F_n=mg\\\Rightarrow F_n=25\times 9.81\\\Rightarrow F_n=245.25\ N$

Frictional force

$F_f=\mu_sF_n\\\Rightarrow \mu_s=\frac{F_f}{F_n}\\\Rightarrow \mu_s=\frac{75}{245.25}\\\Rightarrow \mu_s=0.30581$

The coefficient of static friction is 0.30581

Kinetic force

$F_k=\mu_kF_n\\\Rightarrow \mu_k=\frac{F_k}{F_n}\\\Rightarrow \mu_s=\frac{60}{245.25}\\\Rightarrow \mu_s=0.24464$

The coefficient of kinetic friction is 0.24464

You accidentally slide a glass of orange juice off a table that is 1.1 m tall. How long does it take the juice to hit the ground

sasho [114]

First write down all the known variables:

d = -1.1m

a = -9.8m/s^2

vi = 0m/s

t = ?

Now use the kinematic equation that relates all the variables:

d = vi*t + (1/2)at^2

(-1.1) = (0)t + (1/2)(-9.8)t^2

-1.1 = -4.9t^2

0.22445 = t^2

0.47s = t

It takes 0.47 seconds for the juice to reach the ground.

Assoli18 [71]

Answer:

An reversal in the magnetic fields of the north and south pole. This would be the most logical option for me...correct me if I'm wrong.

Explanation:

New seafloor is formed when magma is forced upward toward the surface at a mid-ocean.
