Answer:
Option A
The drag force goes up by a factor of 4
Explanation:
Fact:
Drag force is directly proportional to the square of the velocity of a moving object
Therefore, when drag force pushes opposite to the motion as one rides a bicycle, the magnitude of drag force increases by a factor of 4
Answer:
The set of coefficients that would correctly balanced the equation
NaCl → Na + Cl2 is the option D
(2,2,1)
Explanation:
In this reaction sodium chloride splits into sodium and chlorine.
For balancing the equation we should have number of atom of the element in the left hand side equal to the number of atom of the same element in the right-hand side.
so here in left hand side only one sodium and one chlorine is given and in the right-hand side one sodium and two chlorine is given.
So for the balancing the equation both the side should be same.
So we will write the balanced equation as
2NaCl → 2Na + Cl2
So, right now it is balanced that is two sodium and two chlorine on the left hand side as well as the right hand side.
Hence the coefficients are
2, 2, 1
Answer:
big
Explanation:
if its big Ryan it gives it a lot of momentum because the bigger the more distance covered
Answer:
The object's maximum speed remains unchanged.
Explanation:
The speed of a particle in SHM is given by :
Maximum speed is, 
If A' = 2A and T' = 2T
So, the maximum speed of the object remains the same i.e. it remains unchanged. Hence, this is the required solution.
