Answer:
0.000136kg/m3
Explanation:
13.6 / 1000 = 0.0136kg/cm3
0.0136 / 100 = 0.000136kg/m3
The correct answer to the question is : C)The problem is asking to solve for work; W = F × d
EXPLANATION:
As per the question, the distance covered by the object d = 29 m.
The force that acts on the object is F = 289 N.
We are asked to choose the correct equation for work done.
Work is said to be done on a body or by a body if the applied force has a component along the direction of displacement.
Mathematically work done W = force × displacement
= F × d
As per the question, we are given distance covered and applied force.
Hence, the correct equation for calculating work done by the object is equation C.
Answer:
no
Explanation:
this is because its valency shell is full so it wont want any other electrons in its valence shell.
Answer:
Time elapsed
Explanation:
Acceleration is a vector quantity. It is defined as:
where
v is the final velocity
u is the initial velocity
t is the time elapsed
Acceleration is measured in meters per second squared (m/s^2). It must be noticed that acceleration is a vector, so it also has a direction. In particular:
- when acceleration is negative, it means that the object is slowing down, so acceleration is in opposite direction to the velocity
- when acceleration is positive, it means that the object is speeding up, so acceleration is in the same direction as the velocity
To compare and rank each one's acceleration, get the acceleration of each person by using the formula, Acceleration = Velocity/Time
Xander = 4.5mps / 3.5s = 1.29m/s^2
Finley = 3.6mps/4.2s = 0.86m/s^2
Max = 7.3mps/1.2s = 6.08m/s^2
Based on the answers above, the least acceleration was done by Finley, then Xander had higher acceleration than Finley, while most acceleration was done by Max.
