Answer:
KE=1/2mv*
Explanation:
write the numbers inorder to the symbols
Ans use this formula to solve the problem
Answer:
Part a)
Part b)
Here final kinetic energy is more than the initial kinetic energy
This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks
Explanation:
Part a)
As we know that there is no external force on the system of two gliders
So here we can use momentum conservation for two gliders
So we will have
Part b)
now we will have
initial kinetic energy of both gliders is given as
Final kinetic energy of two gliders
so here final kinetic energy is more than the initial kinetic energy
This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks
Answer:
B. a conversion factor
Explanation:
The expression "1 in. = 2.54 cm" is called a conversion factor.
With this expression inches can be converted to centimeters.
Inversely the expression can also be used to convert centimeters to inches
By rearranging the equation we get
The statement which shows the equal nature of two different expressions is called an equation
Rule of thumb is a general approximation of a result of a test or experiment.
Answer:
option C
Explanation:
given,
Q = +3.2 x 10⁻¹⁹ C
E = 5.0 X 10⁵ V/m
B = 0.80 T
ion's acceleration is zero
when acceleration is zero the magnitude of both the forces becomes equal.
q E = q V B
v =
v=
v = 6.25 × 10⁵ m/s ≈ 6.3 × 10⁵ m/s
hence, the correct answer is option C
