I am made of literally THOUSANDS of compounds ... too many to list here.
But the one compound that's most abundant, and actually comprises almost
80% of my entire beautiful body, is the compound DiHydrogen Oxide, with
the molecular formula H₂O . This compound is commonly known as "water".
Answer:
cohesive properties
Explanation:
The property of cohesion allows liquid water to have <u>no tension on the surface</u>.
Answer:

Explanation:
We are given that


d=1.9 cm=
Using 1m=100 cm
We have to find the electric field strength.

Using the formula





Mass of electron,m

Substitute the values


Answer:
At time 10.28 s after A is fired bullet B passes A.
Passing of B occurs at 4108.31 height.
Explanation:
Let h be the height at which this occurs and t be the time after second bullet fires.
Distance traveled by first bullet can be calculated using equation of motion

Here s = h,u = 450m/s a = -g and t = t+3
Substituting

Distance traveled by second bullet
Here s = h,u = 600m/s a = -g and t = t
Substituting

Solving both equations

So at time 10.28 s after A is fired bullet B passes A.
Height at t = 7.28 s

Passing of B occurs at 4108.31 height.
Answer:
External force on him = 257.40 N
Equation is; F = ma (where 'f' is force, 'm' is mass and 'a' is acceleration)
Explanation:
The mass of the sprinter is 58.5 kg
His acceleration is 4.40 m/s²
According to Newton's second law of motion; F = ma
External force on the sprinter = 58.5 kg × 4.40 m/s² = 257.40 N
