Explanation:
It is given that,
Initial velocity of the car, u = 14 m/s
Final velocity of the car, v = 21 m/s
Time taken, t = 6 s
Acceleration of the car is equal to the change in speed divided by time i.e. it can be written as :
a = 1.166 m/s²
or
a = 1.17 m/s²
For finding how fat it travel in this time is calculated using third equation of motion :
s = distance
s = 104.7 m
Hence, the acceleration of the car is 1.166 m/s² and distance covered by it is 104.7 m
Answer:
Decreases ,,clockwise
Explanation:
When the switch is reopened then magnitude of magnetic flux through the loop will decreases and the direction of induced current will be clockwise (when seen from clockwise.
So the answer of the fill in the blank is decreases and clockwise.
Answer - B and B.
B) Decreases ,B)clockwise
The car's average acceleration would be 1.25m/s^2 or 1.25meters/second/second. That looks to be the fourth one you've listed.
Answer:
Explanation:
Given that,
Mass of a toy, m = 0.62 kg
Horizontal force, F = 16.3 N
Force on the opposite direction, F' = 15.8 N
We need to find the acceleration of the toy.
Here, two forces are acting in opposite direction, the net force will be the difference of forces.
Net force = 16.3 N-15.8 N
=0.5 N
The formula for net force is given by :
F = ma
a is the acceleration of the toy
So, the acceleration of the toy is 
.
Magnesium chloride is an ionic compound which means a compound composed of an anion and cation.
A cation is a positively charged atom and this happens when it loses an electron. An anion is a negatively charged ion. It becomes negatively charged when it gains and electron
When magnesium reacts with chlorine gas, magnesium gives up its two electrons found in its outermost energy shell and thus become a positively charged ion (cation). Chlorine gas on the other hand gains these two electrons to become negatively charged ion (anion). The opposite charges of these two elements cause them to attract each other creating ionic bonding between them and thus form a new compound, magnesium chloride.
