Answer:
C. A Covalent Bond
Explanation:
two covalent bond form between the two oxygen atoms because oxygen requires two shared electrons to fill its outermost shell
Answer:
F= 9492.12 N
Explanation:
Given that
mass, m = 1598 kg
Initial velocity ,u= 0 km/h
Final velocity v= 93.9 km/h
v =26.08 m/s
Distance ,d= 57.2 m
We know that
v² = u² + 2 a d
a=acceleration
u=initial velocity
v= final velocity
d=distance
26.08²= 0² + 2 x a x 57.2
a= 5.94 m/s²
We know that
Force = mass x acceleration
F= m a
F= 5.94 x 1598 N
F= 9492.12 N
Answer:
Every individual part of a cell has a very important and specific purpose. If even one of these went wrong it would throw off the other parts and most likely damage the cell. They all work in a bit of unison, so it's very important nothing bad happens to one. Hope this helps you out! :)
Answer:
12.46 joules
Explanation:
The formula of potential energy is:
where m is mass, g is gravitational force (9.8 m/s^2) and h is height.
- Mass is given to be 2.3 grams.
- Gravitational Force is defined as 9.8 m/s^2.
- Height is given as 553 meters.
However, mass must be in kilograms (kg) unit so we will be converting the gram to kilogram:
We know that a gram equals to 0.001 kg so 2.3 grams will equal to 2.3 * 0.001 = 0.0023 kg.
Therefore, substitute known information in the formula of potential energy:
Therefore, the potential energy is 12.46 joules.
The correct answer is:
B. Ethel is correct because energy is not carried from one place to another.
Brody and Ethel are arguing about waves. Brody says that waving his hand back and forth is a scientific wave. Ethel says that it is not. Ethel is correct because energy is not carried from one place to another.
