Answer:
Covalent bonding
Explanation:
Covalent bonding is the type of bonding found in all molecular substances much as water, carbon dioxide or methane. Unlike ionic bonding which is found in ionic substances, covalent bonding involves sharing, not transfer, of electrons between the bonding atoms to form molecules.
Answer:
Explanation:
Given,
mass of the bullet, m = 0.0233 Kg
Mass of the block, M = 2.41 Kg
horizontal spring constant, k = 845 N/m
Amplitude of oscillation, A = 0.196 m
Using conservation of energy when the bullet is embedded
PE = KE
Now using conservation of momentum to calculate the initial velocity of bullet
d is diameter, A is the area and v is the speed ,
Area*speed is the quantity of air flowing per second.
A v = πd² v/4 = 1.5 liters /second = 0.0015 m^3/s
v = 0.0015*4/(π*0.0074²) =35 m/s

Using Bernoulli equation
ρ v₂²/2 = hdg where ρ is density of air and d is density of water
h = ρ v₂²/ (2dg) = 1.25*34.8769² /(2*1000*9.8) =0.07758 = 0.078 m
Answer
A reference point is the starting point you choose to describe the location, or position, of an object. The reference point in the first example is your friend. ... The direction is north, and the reference point is your school. A position is an object's distance in a certain direction from a reference point.
