Answer:

Explanation:

The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements, such as hydrogen H, oxygen O and chlorine Cl. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas. The shared electron pair is common to the two atoms and holds them together.

In a double covalent bond each atom contributes two electrons to the bond, that is, two pairs of electrons are shared between the atoms that form the covalent bond.

The Hydrogen atom is made up of a proton and an electron, which is located in its outermost layer and allows the covalent bond to form. So <u><em>hydrogen cannot form a double bond </em></u>because it does not have the electrons necessary to form the bond. It needs two electrons in the valence shell or last shell and it only has a single electron.

Answer: Mars has lower gravity and lower magma buoyancy

Explanation: The gravity in mars is low. Low gravity affect the occurrence of volcanic eruptions. The buoyancy of the magma in Mars is lower and the depth of the magma chamber deeper (Buoyancy is the difference in density between the surrounding crust and the magma ascending for eruption). Olympus Mons which is larger and wider than mount Everest was formed as a result of overcoming of the low gravity and buoyancy by the magma to release enormous volume of magma to the surface.

Another reason why the volcanoes on Mars are so large is because the crust on Mars is static unlike Earth.

A 70kg car drives through a curve with radius 50m. What is the minimum angle the road should be tilted to keep the car on the ro

worty [1.4K]

when car moves along a circular path then centripetal force for taking turn will be provided by the component of normal force

Let the road is tilted by some angle

so force equations are given as

$F_n cos\theta = mg$

$F_n sin\theta = \frac{mv^2}{R}$

now divide two equations

$tan\theta = \frac{v^2}{Rg}$

now as it is given to us that

$v = 80 km/h$

$v = 80* \frac{5}{18} = 22.2 m/s$

$R = 50 m$

now we have

$tan\theta = \frac{22.2^2}{50*9.8}$

$tan\theta = 1$

$\theta = tan^{-1}1$

$\theta = 45^0$

so it is inclined at an angle of 45 degree

Since distance is a scalar and not a vector, the total distance traveled is the sum of all the distances covered throughout the journey.

In Physics, we have two categories of quantities;

Vectors
Scalars

The difference between vectors and scalars is that vectors has direction but scalars do not have direction. Both quantities posses magnitude.

The total distance covered can be obtained algebraically since distance is a scalar.

Hence, total distance covered = 2 cm + 6cm + 5 cm = 13 cm
